Overview
In this episode we test out new modifications for the super cost effective chinese diesel car parking heater, including underfloor heating and auxilary radiators by utilising the waste heat from the exhaust.
I also discus in the last part my thoughts on climate change in relation to using cheap fuels and CO2 production specifically. While I'm not convinced about focil fuels being the main problem, I'm certainly not an advocate for what big oil has done to devistate the plannet in other ways.

Been working with underfloor heating for 16 years. Running pipes through insulation tends to insulate against heat. We put aluminium diffusion plates in the grooves which spread the head out like a heat sync. You’re right about spiral patterns being more efficient than meander patterns 👍

@@chriswharrier3571 Yep. The screed becomes the regulating thermal mass.

Take care M.
As well as the heat exchanger (one from an old combi boiler would work incredibly well, try passing the exhaust air through an old cast iron radiator (empty of water(obvs), get it from a salvage yard) entering in from the bottom on one side and out of the top on the opposite side, it's a larger thermal mass that you need. It will condensate inside so you will need to use the other bottom rad port as an external drain point.
@@RichardFoley3 that's definitely an idea that would work. Cheers J
What would happen if you ran the exhaust through an old car radiator with fan? Massive surface area and blowing the hot air into the room?
@@Fish-bw9yh Probably not enough pressure in the exhaust to overcome the radiator resistance which would back pressure the boiler and cause it to cut out.
@@peterjones6322 Even though it's designed for liquid for rather than just gas? Must admit I've never tried blowing through one 😁 I was also wondering if they were too easily damaged to make them leak fumes.
Otherwise maybe feeding it liquid from the heat exchanger then?
My main thought was that either way the radiator fins and fan would extract more heat directly into the room. 🤔
Yes a car radiator..but dont over heat since may only have SOLDER joints rather than brazed ??
I randomly clicked on this video, then I expected poorly quantified statements but you're pretty on point. The overall topic of global warming is not the main point of this.

@@joshuadelisle Ah - I didn't realise heating oil was actually kerosene LOL :D
I'm a welder/fabricator at a farm in western upstate NY,1200 acre/small farm.I get all the free wood I can cut off hundreds of acres of forest. I heat my shop with wood from the stove I made myself-it's not efficient by any measure,but it works! Love your content BTW
@@garthland wood stoves are the best, I actually have an open fire hearth in our house and I love it. Cheers J
For inexpensive and efficient wood heat, Rocket Mass Heaters are one of the best options.
33:35 CO has basically the same density as air. YES it is technically less dense, but perturbations like a heater fan will just mix it up with the rest of the room air. You need a minimum of 4" from the ceiling/wall/floor so the meter isn't reading only less mixed air, which settles more easily in corners, leading to an inaccurate whole-room reading. It can go anywhere 4"+ away from any surface, so up high is just convenient for being out of the way. If you want a source, Kiddie (a common detector brand in the US) says you can put it 6"+ away from ceiling AND floor.
Silly question but why don't you evacuate the exhaust directly into the radiator. This would avoid going through an air/water exchange. So of course you would have to use an "old" type radiator and I imagine putting a filter or something for carbon deposits.
Small piston airplanes actually use this method, just an exhaust to air heat exchanger.
You should be the next Prime Minister bud - a voice of reason, common sense and sanity!! Thanks for your videos - always a pleasure to watch!!
You're kind to think that. However I make too many mistakes to be that kind of public. I like the fact that I can edit out all my own nonsense. Cheers J
A point on the heat pump Heat Geek installs are averaging 430% efficiency and my install is sitting at 610% so far this heating season. With the OVO 15p tariff that works out to 3.5 or 2.5p per Kwh.
Is that in winter because I don't even turn on the heating until November. Cheers J
@@joshuadelisle So the average for heat geeks would be for the whole heating season so its the SCOP figure.
The figure for my house was just for so far this year.
After a couple of tweaks the system is now sitting at 640% so far this year (if you include hot water 620%). This will obviously go down when the weather gets colder. I'll try and remember to come back and update when spring arrives.
EDIT up to 1st Dec 590% (570% including hot water)
@@MaxIngramRedmayne When its like -2 outside my heat pump runs full chat and barely creates any heat.

Interesting, but what was your capital outlay (in total!) to achieve that? A customer of mine spent £54,000 on a ground source HP, solar panels, and Tesla batteries. However, I worked out that £54,000 would pay his entire energy bill for 18 years minimum. And he has already had to pay for work as the equipment went out of warranty and failed.

@@kingalf4828 thank you so much. Cheers J
Wow what a great channel! Just watched this one and your wood gasification/generator. Heating engineer myself, living in france. The advice in the comments on the underfloor heating is spot on. I myself have just finished my installation of a wood gasification boiler my next challenge is to build a stirling motor from the exhaust gassers that will run the circulating pumps in my heating system. Idea being that the central heating system will run solely on wood! No external electricity supply needed! Keep up the good work!
Nice, well done, I want to also harvest the excess heat for my central heating once i've finished building mark 2 gasifier. cheers J
Love the videos. Just got my deisel heater after a friend demonstrated his in his camper van... and as I spend a lot of time in my manshed with my telescopes, I could do with a little warm.. I was wondering if the exhaust fumes could be pushed through a radiator first before going outside..
@@alecireland5709 thank you. You can but cleaning one may prove to be difficult than less you class it as a consumable part. Cheers J
@joshuadelisle I would use rads that are being thrown out, so it shouldn't be to much of an issue. Possibly cleaning could be done by taking the rad off and giving it a bash with a rubber mallet.. I'm just thinking of ideas before I set mine up..
Nailed it. Thanks for the extensive video. I have a heater sat in a box for the last year waiting on a good idea... Your the best so far and love the gusto in which you present and evaluate. Brit in Finland... Our cold is brutal.... Be lucky.
Thank you so much. All the very best and keep warm. Cheers J
Great content Joshua! Recovering the exhaust heat can of course not only save on heating costs but is also beneficial to the environment by making maximal use of the fuel burned.
I see that you are planning to make your own heat exchanger with a barrel of water. I have long thought that the most efficient way to capture all of this heat is to feed the exhaust directly into a sizeable stainless steel water cylinder (200 - 300ltr) and use a CP fan on the outlet to mitigate backpressure combustion issues. The exhaust pipe would be as short as possible, insulated and connected directly to the flow inlet of the tank. As this pipe spirals downwards inside the tank to the return outlet all condensate will self drain.
The coil is several metres and I suspect will remove the heat extremely efficiently. However, this would result in too much friction for the heater's fan to push and so a cheap low wattage CP fan can be added at the return outlet with the construction of a bespoke adapter. The outlet temperature should be well within the fan's safe operational range. A condensate drain can be added just before the fan and depending upon its size can be used to balance the fan with the heater for good combustion.
The water tanks are plentiful and cheap these days, are insulated, and should already come with the much needed expansion vessel and pressure release valve so that you can't overcook it. If tuned correctly and burning efficiently, an annual service and clean should easily keep the system spotless. I've been wanting to try this out for a couple of years but have not got around to it. Good luck with the next experiment, I look forward to it! :)
Those are great ideas. Thank you. Cheers J
If You need new flooring then that experyment says it all. Thermal insulation under, then pipes on top of that (not into it) then cover with sand or concrete. Edges of the floor need to be insulated, the heat exchanger bit bigger. You can add a water heat buffer (100l /200l) because 40C is max for underfloor central heating. Your heater generates too much heat in a short time (to run efficiently). It's like a wood burner using a gasification process, very efficient, eco friendly, but needs buffer for extra water and a big heat exchanger.
Best plant for o2 production is hemp. There are loads of types without psychoactive substances. As a side effect, (other than o2 production) it grows extremely fast and is better for paper production. Clothes can be made out of it..... Ford made a car out of it, and it ran on hemp seeds oil 1941. Yet someone is blocking that idea.
All the best.
Likely you'll want the pipes running in the middle (height wise) of sand/cement.
@@marcindawid8485 interesting, thank you for the tip. Cheers J
@@mkeyx82 Technically, You should use aluminium foil and tape on top of insulation, Minimum 5cm of mass heat storage (sand cement) up to 10cm, but that depends again on heat saurs, time to heat up, time to cool down ect. In an experimental small scale lab putting pipes on top of insulation will do, and will be much more effective than digging them into insulation. I have downstairs with floor heating at my house, and regret not being able to do upstairs. It is a big energy saving step for a house.
@@marcindawid8485 not sure if we got the wires crossed, I did not claim pipes should be dug into the insulation, just that I expect a more uniform heat transfer to the heat mass (sand, cement) if the pipe is neither on the bottom of the mass nor it is on the top.
This should be easily achievable if the pipes are laid on some sort of spacers, at half the height of the heat mass.
BTW, I am thinking about how a properly insulated floor should look like. Your comment about need to put a tape between the insulation and the mass makes sense. I would expect a moisture membrane should go below the insulation, as well. How to avoid the cold bridge between the wall and the wall?

Top man - brilliant monologue at the end - spot on !
To increase the underfloor heating people wrap the pex pipe with thin aluminium plates that extend outwards parallel with the board on the top (your checker plate) to increase the surface area of the pipes.
Yes you're right. I'll try something like that. Cheers J
I love watching your videos about the diesel heater. I have spent hours trying to research a decent device as it seems they’re all built the same.
Thank you. Lots more to come. Cheers J
Thank you Josh for these updates.
Love your closing dialogue, epic
@@manicminer8813 thank you so much. Cheers J
I rembember watching you last year or two with the previous experiment with the sand and air tunnel. As to your floor heating, you are using an insulated wall panel, with insulation in the name, so all the heat that goes into it is being insulated, so it all goes back out. It is not "lost" into the panel. I don't know how the inside of your eat exchanger looks but surface area/fins are needed to get all that hat into the water. Something like a car radiator, but backwards. In any case, quite impressive getting 45-50°C on a room heater from waste heat. Great results this time.
EDIT: Thought about it right now, you might be able to get a car water cooled intercooler from a turbodiesel, push the exhaust through that and scavange the hot water from it that way. A junkyard will probably have plenty of them. Also as you mentioned, a cooled EGR might also work for this.
As to your initial and last point, even aquarium people inject CO2 into the tank for he plants. Waste energy and efficiency is a much more important part of the equation.
Rubber hose between the copper and Aluminian pipes. Agreed on All else. 🔥
@@bust2boom596 you're right. Cheers J
Silicone rubber hose (sold for cars) is excellent stuff. A straight 18mm bore will comfortably stretch/squeeze to these pipes. Use an inhibitor in the water. Or even car antifreeze.
A long corrugated exhaust run inside a 50mm (2”) aluminium tube with a fan blowing air through will extract the heat. 3 metres of pipe should be enough.
Since they are electrically connected by the medium inside (water) I suspect galvanic corrosion will occur regardless.
Hi Josh, I installed a 8Kw unit on the outside of my house last year when e.on wanted £700 per month for my existing heating system so now that's turned off and I run my heater for 12-15 hrs a day on heating oil and it only cost £2 per day. I have 2x holes in the wall so I don't have the draft issue and I use 2x 10ltr fuel tanks so I only need to top up once every 8 days, on setting No4 which is all I use only uses 3 ltrs every 12 hours.
Im going experiment with an old oil boiler and swap the burner for one of these units as my next project.
Nice. Well done. Cheers J

Love your videos mate. Not only the technical parts but your views at the end. So true!
Good work, Joshua. The difference between the thermocouple and IR thermometers sensing the glossy metals is due to the emissivity coefficient compared to the default 0.95 like in paper. To make them show the same reading, put some paint over that spot you test or maybe a piece of matte plastic tape. I have built a few of these systems and noted that the best system consists of the burner being outside and circulating building air through it. That is the safest option.

Agreed. I came here for the great energy management ideas and stayed for the based perspectives on climate alarmism.
Just wondering your take, since you have a good amount of experience running these machines and tinkering with lots of things, do you think you could mix in used beef tallow instead of vegetable oil? I generally make my own Tallow and use that in cooking instead of vegetable oil, and was wondering if that was a viable option for one of these heaters
Theoretically you can however it needs to be pre heated so it's wet and runny and maybe purge the lines with diesel before and after using the tallow so when its cool it doesn't get blocked up. Cheers J
@joshuadelisle awesome, thanks for the quick reply. I'll try it out, and let you know how it worked
5:00 Joshua, you're making far too much sense. Watch out, or they'll be coming for you!
Lol, probably. Cheers J
Quite honestly your videos pack a ridiculous amount of valuable info on a wide ranger of home-tech matters into them, and links for all of the parts is a massive timesaver. You definitely earned a sub. The lazy part of me wants to get someone with your skillset to come and do all this for me, but your enthusiasm and practical approach has inspired me to start doing this. 8KW base kit just ordered from ebay in the background while watching the vid LOL... I'm sure my bank account is going to get hammered as I work through your kit-list but as it's all modular I guess I can do it in stages.
Off-grid low voltage power and light circuits has been one of my big investments over the last 10years as I've been renovating a little ruin in Northern France but as we all know, there is no real scope for heating with just PV systems so this heater and rad setup is an excellent solution even if I never get around the doing the underfloor heating project. Luckily I have an abundant supply of LiPO 12W batteries from Hospital trolleys linked to some ridiculously cheap solar panels and a good MPPT controller which has allowed me to build up a very large powerbank and this can easily feed the power requirements of the heater, I love that this heater just needs an average 12v power requirement... 12v is king for me ! Nothing worse than having to run an inefficient invertor to get 240v just so I can connect some 15 or 19v psu's
Love the content my friend and once again, thanks for all of the info. You are a credit to TH-cam... Raffall tickets also bought ;-)

I am going to put one if these into my caravan but I think putting the burner high up and use flow tubing to port the hot air into the original hot air outlets of the caravan.
Port the heater exhaust into the top of a radiator and port it's outlet to drip under the caravan.
Your views on this ?
wouldn't it be easier to put a coil of copper tubing inside a barrel filled with water then have the exhausted go trough the copper pipe? seems easy to make and gives you a barrel full of hot water allowing you to store some for later use!
@@kingjustjefgames723 I'm thinking exactly that. A big tank like an oil drum with an exhaust coil inside it to heat the water. Cheers J
@@joshuadelisle
You could see if you can find a second hand single or better still a twin coil hot water cylinder. This will already have nice efficient coils inside, as that's how a boiler would heat the water. The heated water could then be stored in the cylinder, ready to pump around a radiator system.
8:00 in AZ, love your clip,I just would like to say if you were to want hot water & still heat floor mount a tall water heater or tall water tank next to vevor but should mount as low as possible then make your heat exchanger as tall or a little taller & a t at the bottom so u can clean your exhaust of soot, now with thermo syphon flow you will not need a pump but if you use antifreeze you'll need a second heat exchanger the use pump for that, I've experimented with thermo syphon floor heat with a pellet stove exhaust, heated my upstairs apt. No pump, 20' stainless double wall chimney & with the height created more thermo syphon flow plus a tapered poured concrete upstairs floor, apt had a vaulted ceiling on chimney side which created more thermo flow, entered wall at highest point then manifold with 5 lines running down the wall & through the pitched floor then back down to basement to bottom of chimney to cycle again, pellet stove in basement but exhaust heated apartment

This is probably an off the wall suggestion but have you thought of running the exhaust through a thermal store cylinder instead, they are meant to be filled with hot water not exhaust gases but you can take different feeds off for heating or hot water but they arent cheap
Excellent last 10 minutes, agreed with it all!
@@johngibson8900 yes I'm thinking of using a large barrel of water as a thermal mass storage for the next upgrade. Thank you so much. Cheers J
@@joshuadelisle - Water sounds logical enough, but how about simply setting the exhaust in a metal container filled with an appropriate amount of sand, while running the exhaust ports into and out of the metal cantainer filled with sand(?) The metal container of sand, of course, would/should act as an ultra-cheap and hassle-free passive heat sink. However, I could see using water over sand "if" the application is better suited for taking advantage of the steller heat absorbing qualities/efficiencies of water(!?)
@@__WJK__ I already tried that. The sand is a poor conductor but works well above 600°c which the exhaust does not produce. Cheers J
Love it. Can’t wait until you nail this underfloor as I have a garage waiting on it.
Josh I've watched a bunch of your vids, but this one really packed a punch. They way you matter of fact harpoon the madness of the current epoch is brilliant and while I was always a kindred spirit following your maker stuff, I now feel we have even more affinity based on everything you espoused here. Bravo!

@@colinhaig8083 thank you so much. All the very best. Cheers J
37:50 not sure if you get to this but wouldn’t it make more sense to run the in floor heating through something that isn’t such a great insulator? Like you want something that will absorb the heat and conduct it away. Instead you’ve just run the hot water through an insulated loop! Probably running it directly through concrete or some sort of radiator ( that I’m sure you could cook up ) would work better
Maybe a big water bladder or a flat tank. Something that has both a big heat capacity and conducts heat efficiently. The foam insulation has neither and the aluminum top will probably not work fast enough to pull the heat from the water passing through
@@chir0pter you're right but it definitely needs insulation underneath otherwise you lose up to 50% of the energy into the ground and it doesn't come back. However running the pipes through a concrete floor covering as a mass heater is definitely a good idea. Cheers J
@@chir0pter the problem with water is that it's water. Sand would likely do a lot better. Or maybe stone with some cob holding it together. Or simply concrete.

Finally someone who I agree with as far as diet and CO2 goes, we need to form a movement to drive over the Just Stop Oil clan
Thank you. I get why just stop oil are so passionate but they've gone about it all wrong. The important thing is to have dialogue and to have your argument heard and tested in a debate where everyone's perspective is taken into account. It's important to be open to an alternative idea and not be locked in one way of understanding. That's the only way to the truth to come forward because lies don't stand. Everything I've said can be checked but there is even more that I've learned from other commentators which is very interesting. Cheers J
Literally?😁
To be fair there has been dialogue for decades. The oil companies have known about industrial climate change for much the same amount of time. But nothing changes. I applaud JSO for their guts to stand up to it.
@@joshuadelisle It always annoys me when I see the JSO people out with their freshly bought Gortex outdoor gear and plastic hi viz stuff on. Theyre almost covered in new oil products from head to toe, after meeting up and drinking coffee shipped from the other side of the planet out of disposable plastic cups! ut I suppose they have a great day out living on the edge, because roads are dangerouse places to sit down.
I drive an old 300 TDI, run a veg oil mix, and spend many hours weekly working there repairing deer fencing, and lots of maintenance in 80 Achres of young woodland, of which seven of us have our areas and work restoring hard wood woodland. It was a farm 20 years ago, and provides me with fuel to heat my home and water, and is a wonderful place to work, just on the edge of the Cairngorms in Scotland.
I wish JSO would see the light and get into coppicing, pollarding and maintaining what woodlands we have left which are mostly not managed. Managing woodland increases biodiversity and produces lots of wood for fuel and making things; it is also good for your soul.
So I agree, they are going about helping the enviroment by helping destroying it IMHO too.
If you are looking for a more efficient heat exchanger one recovered from a dead gas boiler may be useful. Heat exchangers on house ventilation systems are very useful to save energy.

@@joshuadelisleI’ve learned soooo much from you 👍
Tickets bought 👍
At work our wall convection heater failed and they supplied an oil heater, a bit like the old looking ones. The hut it was trying to keep warm was freezing. I used a summer desk fan to blow the heat through the radiator and this made an amazing difference. Have you thought about just using small radiators with fans to radiate the heat?
Its an idea a few others have done. I'm not convinced a radiator as an exhaust is easy to clean though. cheers J
@@joshuadelisle you could try a fan on the existing radiator that's running on water. Not sure how much heat you'd get though
I completely agree with you. And I will only add that electric cars are not salvation at all if batteries continue to be produced in this way and we do not have a more developed system for obtaining clean, cheap electricity, after all, they also use energy produced from something (coal, oil, gas, nuclear), and everyone seems to think that they are powered by wishful thinking.
EVs are much more efficient than anything with an internal combustion engine, that's a proven fact.
As long as the battery or any other of an EVs components are made using renewable energy, then the initial carbon emissions are also low.
Obtaining oil and gas is a massively destructive and polluting process, this is before the refining and transportation of it are considered. Electricity on the other hand can be produced with little or no CO2 emissions, and the delivery system is already in place, as it's via the existing electric grid.
It dumb to say the EVs alone will solve global warming, but the introduction of efficient mass transportation is a start.
There are plenty of other ways to help reduce CO2, like planting millions of trees, but those are often ignored.
Looking at the bigger picture is the way to clarity of mind, and not fixate on something you might personally not like, like EVs.
I agree that there is a lot of destructive processes that affect the environment in battery manufacturing. Big oil on the other hand is still doing atrocious things to the environment. Both I think can be improved to be low impact and clean. It's the ease of recycle ability that makes me lean towards a combustion engine as it's mainly metal whilst a battery isn't so simple to turn back into a new battery and also the sustainable energy system isn't as sustainable as it appears if you've seen Michael Moore's documentary 'the human planet'. Cheers J
@@johnnodge4327 It's not true that I don't like EVs. I really like their acceleration and larger cargo space, the possibility of using them as an emergency power supply at home or a mobile silent generator for welding machines or other tools. I do up to 100 km on a daily basis and an electric car would be a great solution for me if I had solar panels at home, otherwise it doesn't make financial and ecological sense. Not to mention that I won't earn enough money for such a car for 3 years, saving every penny from my paycheck. But what if the temperature drops to -20 C (and the batteries need to be heated) and I have to drive 200 km somewhere pulling a small, only 700 kg trailer? Of course, another transport option is out of the question because that's why I have my own car available at any time of day or night. And the most important question is how can I fix it myself at home when even manufacturers do not want to fix damaged batteries and this creates a problem of thousands of electric cars in scrap yards because they had a minor accident (Germany/Sweden/Finland/Denmark)? Even in Poland no one wants to touch them, and in Gniezno there are specialists who do miracles with cars after accidents. I can do a major engine overhaul myself, of course by sending the elements for regeneration, but I do not have to take a car with a combustion engine to a special workshop.
I do not know how it is in other countries, but access to public chargers does not exist, not to mention that it is 3 times more expensive there than charging at home. My sister lives in Warsaw (the capital of Poland) and has 20 minutes to the nearest charger by tram!!!! The power grid leaves a lot to be desired, only 5 years ago the power line to my house was modernized (3x240v standard in Poland), after more than 10 years of me asking for some repairs and calling the power emergency service because the voltage dropped below 200v. And now imagine what about charging trucks and, for example, electric tractors for farmers? I'm not an engineer, but I have electrical qualifications and I know what expensive solutions and strong power lines are needed for this. And I will mention that Poland is the largest copper miner in the world.
I won't mention the power plants themselves because in Poland we still don't have nuclear power, we produce from coal and gas. Supposedly, panels and windmills give something there, but it will get very interesting because many houses are switching to heat pumps and the demand for electricity will increase when it's dark and cold and probably windless. Not to mention that everyone will plug in an electric car in the evening to charge. Read a bit about how electricity production looks like for the entire country, it is impossible to change the amount of electricity produced in a split second (even in an hour). When you look at an individual house, the values are tiny, 6 kW per day. Unless I go to weld something or turn on some other tools. Where I work, 60 kW is used per minute of production of one plastic bumper for a passenger car.
And what about industry, construction, emergency services and agriculture or the military? Recently we had a huge flood in Poland in the Silesian region and I wonder how people would charge their cars now since the network is not fully operational yet and that was over a month ago. Why doesn't the military use electric tanks or fighter jets or electric-powered missiles (ion engines are not a myth)? How long would it take a farmer to charge a tractor that was in the field for 16 hours and had to plow 200 hectares per day? Do you know how much energy it takes to literally drag an anchor (plow) driven into the ground?
Why aren't the huge ships that transport these wonderful electric cars between continents powered by electricity? Is it because the energy density in lithium batteries is too low??????
And as for CO2, I understand that you don't mean carbon dioxide but other toxic compounds such as nitrates, sulphates, ring benzoates, soot and other dusts? Because everyone keeps trumpeting about CO2 emissions that nature can handle perfectly well (all you had to do was pay attention to photosynthesis in primary school) but no one mentions plastic production, no one is trying to introduce the trend of using a smartphone for 10 years, or a car for 25 because many things can be repaired but why replace them? Passenger planes have to fly for at least 25 years and that's possible because no airline would buy a plane for 3-5 years.
@@johnnodge4327 the CO2 we have already released into the atmosphere weighs several times more than all of the plants currently on earth combined. 450 Gt of plants vs 1500 Gt of Human released CO2 only since the beginning of the industrial revolution.
Also when trees due they rot and release the CO2. Same if they're burned. The only solution with them is to preserve the wood by doing something like burying it or building something out of it.
You are such a incredible inventor and wise man!
You're very kind to think so. Cheers J

In Brazil our electric bill is at least 2.4x cheaper per kWh and at most 4x cheaper depending on weather. Since we have mostly renewable energy from hydroelectric dams. So we use heat pumps both for cooling and heating. Which makes the equipment cheap as well.

Lot of potential lost from the heated air also - i fitted a 4 outlet end cap and connected one to a length of Arris fence frame tube to carry the air to the other end of the workshop - tube got so hot you couldn't touch it .
Still had the heated air coming out the end as well as the tube radiating extra heat along the way .
What you need for the underfloor heating is the likes of a back off a fridge freezer to spread the heat directly onto the floor plate . Maybe a layer of reflective foil on top of the insulation with the fridge heat exchanger laid on it .
That carbon buildup can be massively reduced if you increase the air into it making it more lean making it burn more efficiently.
I think the long exhaust was a factor as it was set on maximum rpm. Having a short exhaust I think has increased the efficiency of the burn but not the recovery. Cheers J
@@joshuadelisleI just finished watching the video I think the main issue is heat loss through the exhaust so it would make sense to build a massive water to air heat exchanger that is the shortest run possible to not effect the efficiency of the burn, as you stated in the video an EGR cooler would be best but personally i think you can DIY something better with a two part heat exchanger.
Water is funnily enough not a great heat conductor at room temperatures but once it heats up past a certain point it's properties change into a conductor of heat so it'll transfer the heat of the water more efficiently, I would say get rid of the entire hot air portion of the heater & exchange that for a water heating setup then have that plumbed into your DIY EGR heat exchanger for the exhaust which would be a bunch of small pipes that equal if not are greater than the exhaust then have that run outside.
I have a diesel powered central heating system, which also heats a hotwater tank (calorifier) for our domestic needs. What it has, which your system does not, is an aquastat on the hotwater return. This allows the heater to cycle on and off but keep the water pump running. Having more radiators and a larger underfloor system would also help the efficiency.
Great content as usual. Thanks,
Thank you. This heater can't work with an aquastat because it needs to go through a cool down cycle. I theoretically program a controller for it but it's not simple to do. Cheers J
Whilst I agree with your points around the environment and policy. The fact about humanity only contributing 3% of the co2 emissions is false. Also although sunspots activity has increased, the total solar irradiance recieved by earth has only changed from about 1360w/msq to 1361w/msq average
What's your source for it not being 3%. I'll check it out. Cheers J
@@joshuadelisle Do you have one saying it is? I can't find it. Not a credible one anyway. Just social media posts.
Evidence it isn't 3% is in your video: The hockey stick CO2 levels where it goes exponential at the beginning of the industrial revolution. We're on track to double CO2 levels and are currently at about a 33% increase. My best guess at where the 3% claim came from is that someone mistyped/misremembered 33% as 3%.
Humans have released about 3 times more weight of CO2 from burning fossil fuels than the weight of all plants currently on earth. You can't just plant some trees to get rid of that.
are you sure about that solar irradiance? earths magnetosphere catches the energetic particles and gets excited, magnetosphere bands literally pop in and out of place, warming the earth. Stop listening to the junk science.
Suggestion: Amazing video. I have been thinking about this for a while after watching your last video on diesel heater. What i think may work is having the exhaust pipe going down the heat exchanger in a coil shape to slow the flow of heat going outside but at the same time it allows the moisture to escape too.
A few things: firstly; yes human made CO2 is very small, but methane pollution caused by natural drilling etc creates more heating than all the CO2 put together; add that to human created deforestation, pollution creates more heating. On a different subject if you were to charge the storage with PV panels &/or wind turbine the running cost would be even smaller.
True but methane only lasts 10 years before it degrades. Cheers J
Human made CO2 is 33% of current CO2 levels. It's not small.
Natural drilling-as opposed to unnatural drilling?😅
Hi there
Great video.Definitely one of the cheapest and safer fuels to use.
Just a thought could you directly pipe the exhaust gasses through a radiator then to outside.
Maybe with full metal larger pipework and an old cast radiator.
Inlet at the top, outlet at the bottom.
This might get to temperatures like your heat exchanger body.
Then you may be able to run your generator for less time.
Then you could cage it off like you would a fire. To stop you burning your fingers 😂

It's certainly something many people do to their heater, however I like everything to be serviceable and a radiator would be hard to clean on the inside. Cheers J
narrative was a hoax, I decided to dig into the facts to set him straight once and for all. However, as I researched, I encountered information that genuinely challenged my perspective-much of which you cover in this video. This one conversation sparked a deep journey for me; it made me question what other beliefs I’d held as fact that were really just ideas I had absorbed without examining closely. From topics like cloud seeding to historical events, I began to realize that things aren’t always as we’re told.
As someone who has always struggled with weight, I also decided to rethink everything I knew about diet. This led me to a diet based on meat and natural fats, and I’ve now lost almost 40 kg. I feel fitter and healthier than ever before. Interestingly, even though I’m subscribed to your channel with notifications enabled, this is the first video of yours I’ve seen since you first installed the heater. Love your videos, dont be affried to keep speaking up.
Thank you so much Mark. I'm glad to hear you're doing well. May God bless you and keep you safe. Cheers J

Love the exhaust into the polly tunnel to use the free CO2 .
Take care M.
Bill Gates is a Globalist no a politician?
Just a heads COPs of 5+ are not unheard of, primarily with ground-source heat pumps.
Excluding solar, I pay about 0.05-0.0-8euro per kWh of heating and hot water...
Including solar (year round), it's... well.... not zero, but quite close. about 0.01-0.02euro per kwh of heating
Thats excellent. cheers J
Many people seem to think the power from solar panels/batteries is "free", but they cost a lot to install, and don't last for ever. The amortised cost of solar power over their life is approximately 9 p/kWh installed. Battery cost per kWh delivered between 7.5p and 20p. consuming power from a battery charged from solar panels could cost up to 30p/kWh. But using it at time of production could be 9 p/kWh. Use a heat pump with a COP of 4.5 for a well designed and implemented system and that's 2 p/kWh for heating if you only heat when the sun is shining, and 6.7p/kWh worst case. And it's completely carbon neutral (post production and installation).
The other thing I find supremely annoying is that due to the "energy crisis" fuel prices went up for whatever reason. And our response was to dramatically reduce the amount of energy we use. We turned things off, deliberately bought things to produce cheap heat, stuck solar panels our our homes and batteries in our lofts to use cheaper off-peak energy, worked from home to cut down fuel costs, etc.
So what energy companies did was increase the one part of our fuel bills we have no control of - the standing charge.
And all we did was shrug and pay it. There is literally no reason for our fuel prices to ever decrease ever again. We've proven we can pay this, and are willing to spend less money on other things to compensate. I wouldn't put it past them to introduce the threat of power interruptions as a way to make us do something beneficial to them.
Since either there's plenty of power/resources and no problems at all, this is just being done out of greed. Or the system is severely broken, has been broken for decades, and all the quick fixes and patches we've not noticed are starting to fail. It's hard to tell if you're part of the band playing on the Titanic or not until the water's around your neck, but then it's too late.
Very well said. Cheers J
EROEI - The costs of getting resources are rising as they become more scarce. Take oil for example. Now we are drilling in 3km of sea water. it's dangerous / risky and less investors and insurance companies are willing to take the risk. For those that do the pay offs are massive. But when it goes wrong, who pays??? Take Deepwater Horizon for example. Wind and Solar are coming down in price but are not as energy dense as oil. And the one thing you cannot do is reduce the shareholder dividends and CEO bonus.
UK: The richest 350 individuals and families together hold a combined wealth of £795bn - a sum larger than the annual GDP of Poland. Furthermore, the net worth of the twenty richest people in the country has more than doubled in the past decade.

In the 1980's, preservation was a dirty word among 'developing' nations. Instead, it was conservation only bespoken, lest your risked alienating your poor listener into thinking you were going to take away his remote control and make him go back to getting off the couch to change the TV channel. (hint here: the fear of losing was then made the winner) While conserving is good, something to be emphasized surely, a portion of our so-called growth in the past 40years has led to some dimly lit candles among us.

Thank you so much and for taking the time to comment. God bless. Cheers J
Your thoughts are damn right! 👍🏻
Thank you so much. Cheers J
Two things to point out, one that (as others have said) the pipes carrying the hot water for your underfloor heating are themselves insulators and will therefore not do very well at transferring the heat up to the floor itself. Replacing them with copper water pipe would make an enormous difference, but then you'd also need some sort of diffusion so you don't melt your shoes. Sticking with the PEX, stuffing some normal aluminium foil into the grooves above the pipe might be enough to help create a thermal channel to bring it to the larger metal plate, or you could use thermal transfer tape if you're feeling fancy.
The second point is that, while CO2 increases do lead to life bloom (much the same as radioactive fallout does), that's not the same thing as being good for *human* life. Humans aren't very well evolved at all & have real trouble adapting to changing conditions biologically. If we keep cutting down the trees then we will end up with more scrub land which, combined with further extremes of weather (whatever the cause; doesn't matter), will lead to greater amounts of fires, which will further pollute the air & raise the temperatures, which will block out the sun, which will tank the temperatures, which will lead to further extremes of weather. The species has not adapted to these extremes of weather at all, & it doesn't appear that anyone wants to fix that with technology either, so that's going to cause a huge amount of problems down the line.
There is far too much debate about whether humans are responsible, if CO2 is the problem, & so on when none of that actually matters at all. What matters is how we can adapt to the changes that are coming.
You make excellent points regarding climate change.
The contrail documentary seems a bit crazy ngl.
Thank you so much. Geoengineering is very real, Bill Gates has even been funding it. They're even saying that they want to use it to control climate change, that was on a channel 4 news reel that's a few years old now. Cloud seeding has been used for over 60 years. China used it to stop it raining in the Olympics by making it rain in another region. It is crazy stuff I must admit. Cheers J
@@joshuadelisle I remember an old documentary saying after 9/11 in New York there was higher temps due to lack of contrails in sky.
AFAIK Eberspächer, the original inventor of the D4 auxiliary heater that Chinese companies are now copying, recommends using kerosene as an arctic fuel.
That's why I don't think the pump will give up any time soon if you use kerosene instead of diesel.

You Asked: If CO2 Is Only 0.04% of the Atmosphere, How Does it Drive Global Warming?
A: Earth absorbs energy from sunlight, but as the surface warms, it also emits energy in the form of infrared radiation (which we know of as heat) out into space. Water vapor and CO2, however, act like a cap, making it more difficult for Earth to get rid of this energy. Without gases like these to absorb the energy, our planet’s average surface temperature would have been near zero degrees Fahrenheit.
About 99 percent of the atmosphere is made of oxygen and nitrogen, which cannot absorb the infrared radiation the Earth emits. Of the remaining 1 percent, the main molecules that can absorb infrared radiation are CO2 and water vapor, because their atoms are able to vibrate in just the right way to absorb the energy that the Earth gives off. After these gases absorb the energy, they emit half of it back to Earth and half of it into space, trapping some of the heat within the atmosphere. This trapping of heat is what we call the greenhouse effect. Because of the greenhouse effect created by these trace gases, the average temperature of the Earth is around 15°C, or 59°F, which allows for life to exist.
CO2 makes up only about 0.04% of the atmosphere, and water vapor can vary from 0 to 4%. But while water vapor is the dominant greenhouse gas in our atmosphere, it has *windows* that allow some of the infrared energy to escape without being absorbed. In addition, water vapor is concentrated lower in the atmosphere, whereas CO2 mixes well all the way to about 50 kilometers up. The higher the greenhouse gas, the more effective it is at trapping heat from the Earth’s surface.
The burning of fossil fuels affects the concentration of CO2 in the atmosphere. Before the industrial revolution, the amount of CO2 in the atmosphere was about 288 ppm. We have now reached about 414 ppm, so we are on the way to doubling the amount of CO2 in the atmosphere by the end of this century. Scientists say that if CO2 doubles, it could raise the average global temperature of the Earth between two and five degrees Celsius. We are already increasing the amount of energy that bounces back to the Earth. Because of the greenhouse effect, this is causing global warming with its many destructive impacts.
Both water vapor and CO2 are responsible for global warming, and once we increase the CO2 in the atmosphere, the oceans warm up, which inevitably triggers an increase in water vapor. But while we have no way to control water vapor, we can control CO2. And because we are increasing the amount of CO2 in the atmosphere by continuing to burn fossil fuels, even in relatively small amounts compared to the entire mass of the atmosphere, we are disturbing the entire heat balance of the planet.
For more information on how carbon dioxide traps heat, why water vapor isn’t the culprit, and answers to several other interesting questions, check out this post: How Exactly Does Carbon Dioxide Cause Global Warming?

Thank you but I didn't ask that. it is the % that humans have made compared to natural CO2 that is telling. The crabon isn't the issue its the other factors of heat absorption and lack of water absorption from destruction of ecosystems that are a much bigger issue. cheers J
I'm guessing that you're referencing the claim about 0.0012% of the atmosphere is human produced CO2 which you get from 0.04% CO2 current levels and "3% of that from humanity"?
I can't find a primary source for that 3% figure, do you have one? The closest I've got is an Australian news broadcaster and subsequent social media posts referencing that broadcast. It seems this is a typo/decimal place shift of the number you referenced which is a 33% increase in atmospheric CO2 levels since 1850? So it's actually 33% (of current atmospheric CO2 420ppm, or 0.04%. which is 138ppm or 0.014%) from humanity. Not 0.0012%.
Also, saying it's a small number doesn't say anything about how much of the effect it has contributed. The dose makes the poison. A 0.00001% change in botulinum content in a person would take them from healthy to death. The sensitivity of a system to an input isn't necessarily linear, meaning that small changes can cause big responses. An example being a hard ball balanced on another hard ball, where a miniscule disturbance might result in it falling much farther. You can't just say "it's a small amount so it's not that". The question we need to answer is "what is the sensitivity of the system to CO2 levels?" and as @cpcnw eluded, the current evidence suggests it's pretty sensitive!
Albedo of roads is 0.1 vs forest at 0.15 and 0.4 for concrete. Making a ~5% increase in heat absorption between replacing a forest with a road. and roads account for 0.15% of land area. 0.04% of total area. Not factoring in cloud cover. 0.04%*5% is 0.002% difference in how much heat is absorbed. And that's ignoring the decrease in heat absorbed from concrete vs forest. There are heat domes around urban areas due to this effect and it does contribute to global warming, but not massively.
Forests also suck up huge amount of water releasing it through the leaf pores and increase local humidity levels, which decrease local temperatures, but if the local temperature is over a comfortable level then since RH is ~100% people feel uncomfortably hot because they can't loose heat by sweating. They still sweat, it just stays liquid on them as the air capacity for water vapour is already saturated. This humidity condenses in the atmosphere forming clouds that both reflect heat back out of the atmosphere, and act like a blanket reflecting the earths heat back at it. It's a double edged sword. Whether it heats or cools depends on if it's day or night and what the earths local surface is covered with.
@@Leo99929 In the end it does not matter because when Net zero is finalised, we'll all be dead anyway, it's a scam and has been from day one. Regardless of co2 in the atmosphere, what good will it do when food production stops, electricity is switched off along with gas and the fuel pumps are left to run dry. It's all nice and fuzzy debating it, but in the end we will suffer because of a few, which by the way, has been implemented over thousands of years. IF you care for your kids (if indeed you have any) you will stop with the debating and get onboard with the rest of us in trying to stop this net zero madness ;)
Love it! Why not use the water coolant heater version of the diesel heater?
MAO MAO🤠👌
Thank you. Cheers J
Nicely done Josh. Regarding extracting the waste heat, have a think about doing it in multiple stages. Reason being, with direct to water (EGR cooler) if the water is running slowley, it can easily become over heated. Either boiling or creating a failure in the pipes thermal limit. Running the pump too quickly will not allow for the heat absorbtion to be efficient. This is why ERG coolers have multi pipes to extrease surface area for heat exchange and allows for a shorter heat eachange unit to extract the necessary heat, but this is balanced based on water flow speed to desired output temp. The remainder unfortunatly is pushed out as waste heat. Your short EGR with its water flow (as you demonstrated) tops out at 50degC for this reason. Increasing the heat exchange efficiency whether its multi cavity EGR or longer pipe will neccesitate you increasing the thermal mass that its heating (more pipe or radiators) to reduce the risk of high temp failure within the system and possibly increasing the water flow as the temperature rises. Personaly I would build in a high temp safety feature (either electronic cutoffs or a expansion vessle for closed system or a tall pipe from an open vented hot water tank) and also look to add in an air-to-air exchange first ahead of the EGR cooler, (becaise air can handle the higher tempertaures) and also improve your EGR cooler efficiency by either multi cavity or longer run or even multi versions of the same design. But what ever you do, make sure you remove any possibility of producing legionalla.
Excellent points. Thank you. Cheers J
The first 39 minutes was awesome, the last 10 is spectacular!
Thank you Josh, you nailed the climate discussion. I wish more people could understand.
And yes the sun has the biggest influence on our climate along with co2 being a plant food.
A great prospect is that trees grow from the air and not the soil. We see this everyday in our home just by observing house plants growing from a pot of soil. The plant gets bigger but the soil content changes minimal. Yet we are blind to this.
I’ll go just a little deeper, earth must have been smaller in the past
