- This is the second video of me putting the exhaust gases through a radiator. in the first one, i put both pipes at the bottom of the radiator. this is a test to see if it is better to put the inlet pipe at the top of the radiator.
This is a quick experiment to see if i could heat up a normal radiator with the exhaust gases from this diesel heater. well... it worked, it got nice and hot.
nothing exploded or melted.
this is totally free heat, that would have just gone outside!
PUMPING HOT AIR INTO MY HOME
I bought one of these for my garage, and then thought....... I could heat my home with this! So that's exactly what i did! It is working great pumping hot air into my home. It is keeping us nice and warm and super economical.
I have a carbon monoxide detector just in case, but you don't get any fumes indoors at all
.
I hope this may help you in some way. Even if it just makes an idea pop up in your head, of how you can heat your home in cheaper way.
Thanks for looking at my videos cheers Andy..... If you can be anything, be Kind.....

This is very much how a condensing boiler works, it passes the spent flue/ exhaust gasses through a secondary heat exchanger, your secondary heat exchanger is the steel radiator which will rot due to the acidic water produced from the hot gasses condensing inside the initial cold radiator That's why flue's and secondary heat exchangers on boilers are either plastic or stainless steel. Strongly recommend a non corrosive radiator and a Carbon Monoxide detector
Great point!
thanks for looking.

@@andyfireblade Hi! Any chance you can please provide the search string for your radiator? The link itself is not working in the US, at least.
@@taliaperkins1389 try this one amzn.to/3tqQii3 merry christmas andy
I think that's a great idea! The only caution I would recommend is keep an eye on the bottom of the radiator if it's not stainless steel. I know in Canada Natural Gas furnaces use a stainless steel secondary heat exchanger because when the exhaust gases condense into droplets they are very corrosive so it has to be stainless steel. I don't know if this applies to diesel or oil but I just thought I'd mention it.
Thanks for the info! good point.
kindest regard andy
th-cam.com/video/6rQAo8lSLHY/w-d-xo.html this is the other one in the house.
Yes it is very corrosive with diesel too. Probably more so than natural gas. But I bet that radiator will still last several years. I think he said he paid only $20 for it so if it only lasts a hand full of years. I'm sure it would pay for itself.
@@jim4556 this, i wouldn't be concerned at all I'd just replace it when it went bad. These junk/free or cheap radiators are everywhere.....
It’s not just moisture it’s carbonic acid. Uk radiators are ferrous metal. You would be better using an aluminium one if you can
Have you measured the temperature difference between the exhausted gas when radiator connected and when the line is directly without radiator? So you could calculate the temperature "collected" inside the room?😊
I'm an heating engineer. Heating elements usually work better when placed at the bottom of whatever is required to be heated ie, a kettle or oil filled radiator, immersion etc and the heat itself is used to do the circulating. To get the best and maintenance free output from the set-up it's best to have a stainless steel pipe passed through the bottom of the radiator for the exhaust gases to pass through and the radiator sealed to it allowing no leaks from the radiator. Then fill the radiator with diathermal oil to 80% capacity to allow for expansion, heat and bleed air until hissing stops then seal bleed valve. Have radiator very slightly tilted by a few degrees to allow condensate to expel naturally.
great comment
thank you cheers andy and happy new year
Location of heating elements isn't part of this equation. "Engineer"
Well done! My Thermodynamics professor would be very happy with this setup. I’ve just “discovered” these diesel heaters and am very interested in possibly using one to heat my garage here in Western Washington, 🇺🇸. Thanks for the excellent video!
Good man, this is exactly what I have been looking for. Thanks
Awesome set up
Great idea

Keep up the good work, it's a cracking idea to make more use of the lost heat/energy.
Thanks, will do!

th-cam.com/video/6rQAo8lSLHY/w-d-xo.html
@@andyfireblade yes I did, I'm waiting to see whether it's going to be any cheaper to heat a home with 1😃👍
I like this idea and will adapt it to my garage. I have a dehumidifier that runs 24x7 to protect the expensive motorbikes from corrosion. It samples the air every 30-minutes to see if it needs drying. Your solution would raise the temperate to allow the air to hold more moisture and reduce the energy used to dehumidify the cold damp air. This could reduce my household bill by 50% because maintaining a damp free garage doubled my energy bill. Great informative video.
thank you graham, your set up sound great. the good thing about these heaters , is that the heat given off is dry. the "burn" fumes go outside though the exhaust. i have had diesel heaters in the past, and the condensation would be dripping down the coldest walls and rust my tools .
i have a Kawasaki er6n 650 at the moment by the way, no fireblade at the moment.
thank you for your comment did you see my other heater vids, www.youtube.com/@andyfireblade let me know what you think, cheers andy
I had a similar idea when I saw these diesel heaters, well done for having a bash. Some thoughts I had were rather than passing the exhaust gases directly through the radiator, another way would be to feed it into a shell and tube heat exchanger. The radiator can then be filled with thermal oil and a small pump attached to circulate. Should eliminate the condensation/corrosion problems and the heat will also be retained for longer in the radiator. You can easily expand the system with more radiators as well if required.
brilliant idea my friend. yes just experimenting but thats a good one, i might have a go at that.. and thank you for watching.
kind regards andy , did you see my other heater , heating the house.
th-cam.com/video/6rQAo8lSLHY/w-d-xo.html
@@andyfireblade Just watched your latest video. Awesome job and seems to be working a treat, are you going to try it with thermal oil? The oil should be able to get much hotter than water as it won't boil. Might also be worth considering bringing the exhaust pipe straight down from the heater to the tank, at the same level as the bottom of the radiator and then out the wall , sloping slightly downwards to ensure any condensation is exiting the pipe. I think this is a fantastic first attempt though and proves the concept very well😁😁😁
hey fast eddy

great idea! If the exhaust still comes out that hot, my guess is the heater could even handle a much bigger radiator.
yes, thats true

I often thought about putting the exhust through an indirect cylinder and seeing if it would heat the water. Judging by your through a rad experiment I feel confident this could work and therefore a cheap hot/warm? water supply for off grid.
yes , please see my other vids www.youtube.com/@andyfireblade
Nice job Andy. I have a similar set up, only I ran my exhaust gas thru a 10 ft long 1" & finishing through 3/4" copper pipe which is a fabulous conductor of the heat keeping that much in the room.
(Summer house)
Regarding the condensation / steam from your exhaust. Almost a definite result of clash of temperatures. I tested the heater without the extension pipe and yes it ran clean & dry (no steam)
I would advise from my findings that your exhaust needs to be heading downhill the whole way out as you will eventually have condensation blocking on that low point on your exhaust.
Thanks for the vid. Ray

Improvement idea:
Put the radiator in the next room.
This maximize the use of the heat.
The heater itself heats up the room you place it in.
thats true, you get enough heat from the heater its self in that room.
thanks for looking.

This is a great idea though you really want to have hot gasses going into the bottom of the radiator and out the top but then you have to deal with condensate. This could be done with a separate narrow pipe coming out the bottom. Also get a stainless radiator as the cheap steel ones will corrode like crazy because diesel exhaust gases are corrosive.
Great point! cheers andy
I'd love to see a couple of those little sterling engine fans on top of the radiator to move the air around, this is a really efficient set up overall..
good idea, cheers andy
@andyfireblade Love the channel man, I've been binging your content. I plan to Insulate my two car garage and get an "8kw" Heater for the winter. Your content is full of great ideas, And I'll be putting them to good use next fall. Keep rockin
Hi Andy.....I think this is a great idea. What is the size of the radiator? Do you think you would it be better to use a larger one? What connectors did you use to attach the exhaust pipe to the radiator.
hello john, yes this is just a small 500mm x 400mm i think.
it was just the cheapest one at selco builders yard. for the experiment.
a much bigger cast iron one would be better.
i have been told that you can heat the biggest rad with one of these.
did you see my other videos, i have one of these heaters heating my house.
kindest regards andy
Nice to see the experiment and thanks. It would be interesting to cut a generic radiator open after a couple of months and see what it looks like inside ! Obviously not yours Andy !🙂
Thanks for the idea reg! another video? hahah . thanks for your comment regards andy
It will badly corrode a cheap steel radiator like this, you really want to use a stainless radiator.
Let’s look at some simple Physics/Chemistry.
Supposed 5kW (likely provides circa 4kW of warmed air), running at only half speed (H3) setting (~2kW) is very unlikely to be providing the ‘more than 2kW’ from exhaust heat recovery - it would be virtually all the energy input to the heater!
Temperature is not the same as energy.
Fuels contain some sulphur which will burn to suphur dioxide/trioxide and dissolve in any liquid water to form sulphurous/ic acid which will dissolve both mild steel and copper.😮
Exhaust gases should be kept above dew point or condensation will occur. Above 100 degrees Celsius, at the exhaust outlet, would alleviate the condensation problem, but restrict the amount of heat recovery from those exhaust gases to approx 2/3rds of the total available. Cold surfaces in a household radiator will always allow condensation within the flow path.
Apart from the risks of eventual exhaust gas leaks (these heaters are not certified for indoor use because of potentially lethal CO poisoning), an EGR cooler from a diesel engine with exhaust gas recirculation would, I think, be a better/safer way to recover any reasonable amount of the exhaust heat available.
But, as always, there will be those that ignore (or haven’t a clue of) the safety, to try to extract a little extra heat, so will carry on regardless.
You can get something that comes in a tube like a silicone gun thats for sealing up industrial furnaces (EFW Plant) I think it goes to 800c you should seal up the exhaust. It may be ok if your room has a positive room pressure, if it goes negative with the likes of doors opening you risk drawing fumes back in.
Love your set up. Keep an eye out for corrosion in the rad and keep detectors near by
brillian thanks.

You've probably got a good bit of moisture building up in the bend after the heater but before the radiator. So raise the heater to make sure the exhaust goes downhill. You may need some ducting to ensure better mixing of the air down near the floor. So pull cold air from the floor and pipe the hot air out near the floor in such a way as to not put it in with the. Older intake air.
Thanks for the tips!
kind regards andy , did you see my other heater , heating the house.
th-cam.com/video/6rQAo8lSLHY/w-d-xo.html
Just after the heater before the radiator, it’s about 250c. No moisture is condensing in that section of the pipe it’s too hot
I was thinking it might benefit to have a fan running across the radiator, but I'm no expert.
I wonder if radiator back pressure would affect the heat-unit? Great idea & experiment! Bravo!
good comment, its quiet free flowing
cheers andy
It seems to me that the best option would be to use an antique cast iron steam radiator, mounting the heater higher than the lower fitting (so that any startup and shutdown condensation doesn't migrate back into the combustion chamber), then plumbing the exhaust into the lower fitting, out the top and then to the outside. This method would mitigate the condensation concern (especially if it's run long enough for everything in the exhaust stream to heat up enough and prevent moisture from collecting), along with hopefully creating more even heating in the radiator.
The only thing I'm completely stumped with is just how large of a radiator could be used before you see diminishing returns. Obviously you'd want the largest you could realistically use before reaching that point for the sake of scavenging as much heat as you can.
my thoughts exactly, i would like to try a big cast iron radiator.

Hi again.
Another good idea is to get a little temperature machine to see how much the room warms up and how fast.
yes , i must do that. although the garage is not that well insulated.
thanks for watching. kind regards andy
Add an STC 1000 or similar controller, they do 12v ones. Have the probe sensing the radiator. Add fans (on a plenum at the bottom of the radiator pushing air up the back of the radiator thru the fins) also 12v so computer fans. The stc needs to see 65c or so before switching the fans on. So you get an increase of air flow over the rad. This will again increase its efficiency.
Holding the fans off with the stc will allow the PSU to cope with the glow plug load etc.
STCs can have 2 probes, so you could in theory use the second one as a room thermostat, and control the heater with it, again adding efficiency.
hey tony, you know your stuff. thanks for watching and thanks for the great tips. kindest regards andy
very cool.
thank you for your comment did you see my other heater vids, www.youtube.com/@andyfireblade let me know what you think, cheers andy
Maybe you could coil a small diameter pipe around the exhaust pipe and pump water through it to the radiator !
Hi Andy,what gave you the best results with the rad.was it the direct exhaust input or heat exchanger ( cu pipe wrapped around the exhaust,) ? cheers.
the exhaust straight through got hotter. but for a long term lasting system , i would use the heat exchanger .
cheers andy
It would be interesting to see how you fitted the 24mm exhaust to the radiator as they usually have 15mm tube
thanks for your comment
i hadent put the valves in the radiator holes. so the hole was perfect.
thanks for your comment, kindest regards andy
That's really amazing!
I wonder if you got one of those thermal electric fans that go on top of wood stoves if it would help to move some of that heat around the room a little better.

Cool! One question though. If you read the manual, they say that you cannot obstruct or lengthen the exhaust pipe due to back pressure, inefficient burning etc. Causing waste buildup in the burner. How is this effecting the burner after a few months? Thanks
your right, but i havent used this long term.

Very interesting and FAB
thank you my friend xxxx
*EXCELLENT IDEA RECOVERING WASTE HEAT, TOP TO BOTTOM.*
thanks a lot, cheers andy
Nice!
Thank you! Cheers!
Panel rads have a baffle fitted inside the bottom part. So connection at bottom opposite ends will allow the top to get hot but will also cause condensate to become trapped.
thats good to know, thanks andy
I Russia where they have done this on several channels they used cast radiators as the exhaust condensate is quite acrid - they claim up to 1.5 kw of heat can be recuperated at full power
Thanks nice video, So how many radiators can you attach to one of those diesel heaters , do you think you can attach about 5 or 6 radiators, and what is the fuel cost when compared to gas or electric for the year?
i dont think you could att more.
maybe a bigger cast iron one would be good?

The reason for the moisture is the gases from the exhaust have cooled past the due point which means any moisture from the air prior to burning have started to condense back to water

You should put a PC Fan under the Radiator for better thermic and install a CO monitor next to the heater.
Any update on this? Id worry about it rusting out the bottom of the radiator. I'd be inclined to use the exhaust to heat water and plumb the water into the radiator. Maybe through the use of a separate heat exchanger. I have a diesel heater and im looking at my previous suggestion, or to build a sand battery
the heat exchanger with water is a really good way to go.
www.youtube.com/@andyfireblade
cheers andy
I’d like to see this with a heat exchanger and closed circuit loop. Does it need a pump to pump the coolant around the closed loop or does the coolant move due to pressure changes as the coolant becomes steam, etc? That should mean the radiator retains heat longer too if there is hot coolant in the system??
I actually want to apply this (theory) on my boat using the exhaust gases to heat my hot water tank through the integrated heating coil .. if it will work.
you are exactly right.
i have tried this with out a pump and it works just as well.

Hi Andy, great vid! 👍 How are you connecting the radiator to the exhaust pipes, please?

Maybe wrap the exhaust coming off the heater with Header wrap that race car drivers use.... Keep the heat in that pipe until it gets to the radiator.
good idea!

That’s marvellous, I really appreciate your ingenuity.
If I may make a suggestion? I think that if you connect both the input and output pipes to the bottom of the rad then the rising hot fumes will heat more of the radiator than that peculiar top in and bottom out arrangement.
That would also improve the flow because the input will currently be fighting against the tendency of the hot fumes to rise.
I must say that I share some mentioned concerns about the exhaust fumes causing the mild steel rad to corrode from the inside.
thank you my friend

Try a series of bends in the large pipe with a radiator at the end to keep the heat in the larger tube maybe heat sink on the top to put the hottest heat in the air while effective.

Great idea, I would though recommend to pay attention to the exhaust pipe slope, the highest point should be the exit point from the diesel heater itself then the lowest point should be the far end opening (outdoor), to make sure that all fluid condensation is out neither gathered in the radiator nor back to the diesel heater!
Thanks for the info!
Cool setup but from the angle I can see on the exhaust, it rises up to join the rad, meaning most liquid in the pipe is going to sit under the inlet to the rad
thank you for your comment did you see my other heater vids, www.youtube.com/@andyfireblade let me know what you think, cheers andy
What fixings did you use to go into the radiator from the exhaust pipe fella?
i didnt use a valve, so there is a bigger hole for the gases. and then i used a piece of the inlet flexy hose to go over the rad neck with a jubilee clip to hold it on.
great comment my friend.

Great video,seen a view vids on recycling exhaust gas for extra heat,yours looks the most original and effective.
thanks for watching, not a long term. but some similar in my other videos. please take a look at them, let me know what you think?
i prefer the one where i heat the water up in the radiator, i think that is better long term

Interested to see how cold the exhaust is when it exits, gives a clue how much heat is being taken by the rad.
yes thats true.
it is cooler.
i will measure that
kindest regards andy
Always thought about running some pipe work from an exhaust whether it from a heater like that or even an open fire, have the heat from exhaust/burnt materials pass threw pipe work in my above ground pool, not sure how far exhaust gases would run horizontally before may become an issue, but as your getting quite a lot of heat as you show that you can’t even touch it suggests perhaps a straight length of stainless steel pipe running threw my pool water may just take the edge of it, the missus works in an outbuilding and we currently use electric panel heaters but are going to fit one of these heaters, as she works in there for 7-9hrs 5 days a week,,that’s would be a fair amount of spent heat passing threw our pool water, may just give this a bash. To me it’s all about trying different things that spent heat should be re used on something else,
I remember a workshop I worked in had these single tube type radiator bars running the length of walls and you couldn’t touch them they were so hot, that was the only source of heating and that workshop was always toasty.
good plan. yes stainless would be good and a wider bore to reduce back pressure.
please take a look at my other vids, let me know what you think?
www.youtube.com/@andyfireblade
cheers andy
i would have thought a exhaust heat exchanger would be a better way to do this, surely any resistance on the main exhaust outlet would cause the exhaust gasses to be forced out elsewhere as they aint the best made things?
yes you are right.it would be . or using heating water to go round the radiator. certainly for long term use. the gases dont really pressure up in there. there are fairly free flowing. but thanks for your comment. th-cam.com/video/6rQAo8lSLHY/w-d-xo.html regards andy
Wonder if you had 22mm copper pipe and bent it like a towel heater radiator and heated it from the top and the condensation out of the bottom

One question: Because of the restrriction of the exhaust, is it possible that the pressure might go too high which will cause some of the exhaust gasses to slip out the other end? I don't really know how these heaters work FYI.
yes, it does give some exhaust restriction, but none leaked out where it shouldnt.

let me know what you think,
cheers andy
@@andyfireblade Yeah but only two including this one. I'll take a look at the others ones.
An automotive heater core with a fan would probably crank out as good as the heater itself.
Just make sure to keep a co2 and low oxygen detector around.
This is much better solution as the exhaust gasses and the air flows against each other. This is the most effective method of heat exchange. I have a 🙋 how did you connector the exhaust pipe into the radiator. Could you describe it more precisely please? Maybe some sort video?
the flexy pipe goes over the neck of the radiator, then clamped with a jubilee clip
kindest regards andy
Very good. I was wondering if you ran that exhaust pipe through a metal tank of sand if you could capture longer lasting heat .
Great point!
like a storage heater?
i have another one heating my house up, it is outside in a box.
with a 4" hole in the wall piping the hot air in. heres a link if you would like to see it th-cam.com/channels/3sYHaAZtJI-vrD64K7Qe9w.html kind regards andy
Try positioning the heater so the fan will blow over the radiator also. Pick up a carbon monoxide detector also in case the radiator system develops a leak.
Great idea
thanks , and thanks for looking

I feel like you could be using a much bigger radiator here. I would be tempted though to try to coat the inside with something to protect from the condensate. If there is a suitable paint type coating one could fill the radiator up with it to ensure complete coating and then drain the excess and leave it at an angle to drip drain as it dries out over several days. Not sure what you would do with the leftovers 😂
good idea,
thank you for your comment did you see my other heater vids, www.youtube.com/@andyfireblade let me know what you think, cheers andy
Hi Andy just got a question how have u joined the exhaust from the heater to the rad as looks like black rubber pipe but won't that melt as I want to use a rad to make more heat from my diesel heater so I can just have mine on leavel 1 heating
i used a metal flexy pipe and pipe clamps.

let me know what you think,
cheers andy
@andyfireblade now goin to have a watch thank u mate
Yes ive seen that video before so how do u get the flex pipe to stay in the rad
Interesting ! You may get condensation between the exhaust on the diesel heater side and radiator.
as the unit cools, it will pull moisture from outside to the last bit of heat source.
I wouldn't be worried about radiator to exterior side.
it would be nice if a person could find a dual core radiator. and fill one core with water. and core two as the exhaust side.
it would be like a water battery.
Great point! that is what was in my head, but it didnt come out until you said it, cheers andy
Would the water side be sealed?
It looks good but you have a trap on the exhaust between the heater and radiator id either place the heater higher or further from the radiator to straighten the pipe or shorten the pipe.
thanks cheers andy
Hi Andy can you give the name of the heater and where you got it and a link for the pipes you got for it thanks
here are the links, kindest regards andy

try the intake at the rad bottom & the exit at the top because as we all know hot air rises so the middle of the rad should benefit a little better ...your next experiment ..look forward to the results
i did this in another video, please have a look at my other videos.
cheers andy
Might make a good silencer as well.
good point!
What a racket it makes 😂
hello my friend
yes, these are quiet noisy. you have inspired me to do a video on the noise, so that people who are thinking of buying one understand.
cheers andy
Hi again Andy danny here again just asking as looks like u now got 3 diesel heaters to run ur home and garage not sure how much ur paying for fuel but what about getting a how oil tank to supply the heaters with fuel may be cheaper than useing diesel and having to keep filling them up every day just an idea let me know what u think mate
good idea, thanks danny
merry christmas
My gas whole home generator box when it's running even though exhaust is vented gets to around 40c from the air blowing through the engine. Using exhaust gas as a radiator is genius
I wonder if, when the gas heater is shut down any exhaust fumes can come back out. That might be a risk. Of course a CO detector (or two) would help plus maybe a valve on the exhaust pipe could be put on to shut it.
thanks andy
Heat always rises! (just look at our extreme weather!)
try placing the exhaust on the bottom, outlet to outdoor on top.
Actually, I run the exhaust indoors at only 5ppm (with a door open), for extra heat 'n warmth.
Specially that it's summer and hot weather makes it ideal for testing......
Placing the exhaust on the bottom, outlet to outdoor on top? Where should the condensate go? I think it is fine as it is, because pressure will push the heat down and through the system.
@@elbuggo The Heat should 'Vape' it mate. ;) Cheers! 👍
What about running the exhaust through or around a small water tank (separated) and have a pump circulating the water in the tank.i Imagine the radiator would stay hot much longer.
Or through sand as a sand battery - that would be even better (unless you wanted hot water). Sand can hold heat for hours.
yes, long term, i think thats the way to go. good comment. regards andy th-cam.com/video/6rQAo8lSLHY/w-d-xo.html this is the other one in the house.
Hi Andy , just fitted my heater in the garage nightmare to prime but sorted now , how are people fitting the control unit ? Double sided tape ? Had loads of smoke on start up but clean now and silencer isnt making any difference sound wise but fitted. Exhaust and air pipes at the moment go outside through some luckily existing holes . Andy all this is new to me and think am worried about everything lol , even put a flag stone at the end of the exhaust. Checked the cavity of the wall and cant see any rock wool . Andy bless you if you reply to all of this message 😂😂
i was totally the same, i was worried that it was going to blow up. the sound of these building up, like a jet engine is initially scary. yes smoke on start up is normal . and the initial prime problem is normal too. the exhausts are not really worth bothering with, but if you are resourceful you should be able to dampen or deflect the noise somehow. you can use a motorcycle exhaust. when i have the control unit separate to the machine, i used a couple of self tapping screws.
it sounds like you have served your apprenticeship now, you can now start to enjoy the rewards for you hard work, and you will be able to leave this on for hours without worrying cheers andy
@@andyfireblade cheers Andy
I am not sure whether I'd have put the input at bottom and outlet at top since heat rises. Only a thought. I haven't seen previous vids so may have missed info. The other thing is reflective surface behind the radiator. 🤔 Some kind of cover over rad to stop little hands
thats true, yes it does get very hot.
thanks for looking.
did you see my other heater videos www.youtube.com/@andyfireblade
cheers andy
@@andyfireblade What's the law governing these ?
Personally I'd have radiators stacked if this were installed in a property. Using convection to heat water..maybe install a pump to move heated water ? I'll check out the other vids at some point. 👍
@@whoisme678 thats a really good idea
Could you fill the radiator with oil (Kerosene), then make a closed circuit & a coil of copper pipe with exhaust running through he centre of the coil? The copper pipe coil would act as a heat exchanger & the radiator oil would retain heat for a while after shut-down
thats a good idea.
someone else said a similar thing about using an oil radiator. to store the heat, good point.
did you see my other heater heating the living room.

have a great day andy
@@andyfireblade no, I'll check it out. thanks
Great video, do you have a link for the radiator? It's not working.
thank you my friend
there are a few here, but the prices have gone up slightly.
