- This is a quick experiment to see if i could get hot water with the exhaust heat from this diesel heater. i didn't think it would work.. well... it worked, it got Really hot!
nothing exploded or melted.
this is totally free heat, that would have just gone outside!
please send comments.
• Heating My Home with a... this is the other one that is heating the house.
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.....

You could run a few metres of flexipipe coiled up into a sealed water barrel and that would heat up during the day and keep the garage warm overnight due to the thermal mass. I'm considering something like this for my outside office as it's always freezing in the morning . One good thing about this (intentional?) energy crisis is that it makes this kind of mad experimentation become mainstream and that's a great thing :) Keep up the great work mate!
thank you my friend
great idea. we are all trying our hardest arnt we.
cheers andy
The flex pipe would have to have a reservoir with a safety relief valve to avoid making it a bomb if it overheats and creates steam.
Another great video. After your radiator video I bought a Galaxy EGR exchanger which turned up yesterday - looking forward to a bit of free radiator heat.
thank you my friend.
brilliant, i hope it goes well let me know how it goes, and have fun.
kind regards andy
Apart from the inventive aspect.... what a nice guy you are Andy 👍My missus and I are just starting on our heating adventure and given us some fantastic 'food for thought'...... and spirit in the current (cold) climate. Just had our gas bill in and had to break open the smelling salts !!!!! 🤣 Subscribed.
hahaah.
thats brilliant my friend
thanks a lot. and good luck with your projects.
message anytime.
kindest regards andy
Brilliant use of wasted exhaust energy! 👍 in the process of fitting a heat exchanger to my diesel heater!👍
Glad it was helpful! thanks for looking in,
good luck with yours, cheers andy
Brother I absolutely love you 😂 please keep up these experiments. I do look forward to them
Glad you like them!
thank you so much for your support.
kindest regards andy
Hey, just a suggestion for better exchanger efficiency - use counter-flow. Meaning that the flow of gas is opposed to the flow of water. I am studying thermodynamics right now and the difference is noticeable
hello my friend
, i am sure there are loads better ones out there. i only got this one because it was just £15.
thanks for looking and good luck with the thermo- watsabobthingy
have a fab evening my friend
regards andy
I'd have never thought of that!
@@andyfireblade he's saying to have the water flow the opposite direction as the exhaust. Like make the exhaust go left and water go right type of thin.
@@anthonyjulson8840 Yep, the coldest water should be extracting heat from the coolest exhaust gas. Consider [the] (your) best system where the exiting water is as hot as the exhaust gas - it won’t be collecting any further heat in that scenario.
Edited so you can ignore the square bracket ‘the’ and insert the curved bracket ‘your’ instead, to make more sense.
Another great idea there Andy,I just got my heat exchanger today,so I will have a play with a radiator tomorrow
brill, Have fun, let me know how you get on,
message me anytime.
regards andy
Proper loving the experiments your doing. Give it a another few weeks and you’ll be bathing, washing, and heating the house, if not the street from this!! If you do go down the moonshine/poitin route, I’ll have a jugs! 😂
hello paul hahahahahha. thanks for popping by again.
have a fantastic day regards andy
Glad you got round to doing my early suggestion all be a little different for hot water.
Another thing I was thinking of was heating the water via a heat exchanger but running it through a car heater matrix with a fan behind it blowing hot air out just like a car heater setup.
Thanks for the idea! i will get one.
and thanks for watching kevin
have a lovely evening andy
Loving the experiments
Keep them coming
thank you my friend
have a lovely evening regards andy
Another great video Andy, Thank you .👍
Glad you enjoyed it
thanks gary
have a lovely evening andy
Should try getting hold of an old car heater box (mini or landrover), and then pipe the exhaust through the heater matrix. With its own integral fan it might work as an additional fan heater..
hello my friend
thanks for watching.
i have just picked up an intercooler with a fan.
that i might try!
cheers andy
Cool. I agree with the earlier comment that it would be worth checking for an internal leak in the cooler, that condensation should have quit showing after a few minutes of running. I'm giving the oil cooler fan heater version a go soon, using a Mercedes cooler in a low volume closed loop pressurised setup in the hope the temps get that far, they all seem pretty similar, I went for this one because the exhaust fittings are best for me to work with. We'll see 😁
hello my friend
good comment, you probably right there!
good luck with yours
cheers andy

@@andyfireblade No leak (well, very unlikely), just latent heat of condensation that you’ve not removed in the heat exchanger. Water of combustion has to go somewhere. If your heat exchanger cooling water was plumbed the other way, you would likely be getting liquid water in the exhaust pipe.
Love it. Can’t wait to see what you try next. 👍🏻
hello again my friend, thanks for looking in.
running out of diesel heater vids. only have about another 15 left.
hahahahaah kind regards andy
EGR coolers ally, so the tap water would destroy it pretty quickly, a coil with a scrap car reservoir in the bucket would work long term though. Then you can fill the coil reservoir with distilled water and auto antifreeze.
great cheers andy
Just a tip when using IR to measure temperature. The surface can't be shiny silver as the reading will be inaccurate, ideally you should paint a bit of matt black paint or similar.
thank you michael i didnt know that
kind regards andy

The condensation is coming from the fuel. You get it cool enough it will have water running out. It is the purpose of the drain in the muffler.
Add black matt high temperature paint to areas where you will measure temperature. Hold temperature meter close to measuring point. Laser red dot is for aiming but does not measure any temperature. Read manual and you will understand.
thanks
cheers andy

I'm glad you said condensation 😁👍
😁
I like the idea of using an EGR cooler as a heat exchanger but my worry is that once the water is boiling it will just make steam, potentially very dangerous. The only solutions with this setup are: 1 drain off some water and add more cold water; 2 turn the heater down/off.
An alternative heat exchanger would be one from a Mazda 2.2 diesel from about 2010. These have a bypass tube and diverter, operated originally by vacuum which could easily be modified to cable or electric servo.
hello chris, good point. i thought exactly this, but no one else has ever bought it up! the water will keep getting hotter! hhhmmm. i am going to do another similar experiment, but you have really got me thinking now, about that.

👍👍👍👍👍
hey
I'm really enjoying your video I'm really tempted to pick up one of them heaters
Could you possibly lose the red around your thumb nails, please, as it makes it hard to tell what videos I've already watched
hello my friend
thanks for watching
i never thought of that before. thanks for pointing it out.
have a lovely evening regards andy
Hi. Liking your great experiments. Do you know what the heaters maximum exhaust length could be? As I am thinking of running the exhaust pipe around my garage walls, using the hot exhaust until it cools, then feeding the exhaust outside. Keep up the good experiments.
hello Craig, thanks for looking in here.
well another youtuber told me that he had done exactly that!
using a 22mm copper pipe, going straight through a summer house. using the heat from the pipe whilst sending the fumes to a convenient exit location. so i think you will be ok.
cheers andy

Double up with the egr in series with each other to use up every bit of heat from the exhaust before it leaves
hello my friend
great idea, makes sense.
thanks for watching
kind regards andy

@@andyfireblade Noo. One heat exchanger,plumbed the right way, is probably adequate.
Thanks Andy. Wondering if you put the noisy "clack clack" diesel pump back on your test heater as it seemed to be a bit noisier ? I've ordered one of the quieter ones. Cheers Reg
hello reg, how are you my friend.
yes the quiet one was great and then it went a little noisy sometimes.
i am working on it. that it the old one in there today.
i have some plans, but i did wonder weather it was do with me using kerosene (being thinner than diesel).
what do you think?
kind regards andy
@@andyfireblade Hi Andy - yes that's an interesting one - and annoying after you paid twenty odd quid for it. I haven't seen anyone else reporting a problem with the silent ones going noisy after a while yet but of course they are probably mostly using diesel or thicker oil with them. I found this page which is talking about diesel engines (not specifically Chinese diesel heaters) but it does say that one negative with kerosene instead of diesel as a fuel is the lack of lubrication in kerosene that can affect diesel pumps. I know that ensuring proper lubrication to the chinese heaters original diesel pumps when running on diesel is why they need to be tilted on that angle. If your kero fuel is not lubricating the new pump properly then the wear and tear could possibly be the issue with it going noisy after a time. I wonder if there is an additive that you could safely add to the kero to add back in some lubrication without defeating the cost advantage of kero ? Not sure how the silent pumps differ from the standard noisy ones and whether kerosene would affect them more (ie what makes them silent) - if I find anything online (or anyone else might know) we can let you know. Also interesting that the link states that kero is less efficient and therefore produces less power (in an engine) than diesel whereas I originally thought the opposite. I don't know if that "less power" would translate into "less heat" from your heater though 🙂.

@@regwatson2017 hello reg thank you for your help. i have heard from someone running one kerosene for 4 years on the same pump with no prob. and if my pump did fail as a result of running on kerosene eventually i would mind to put a new one one for the price of them. and hopefully would have saved a lot already on the cheaper kerosene.
Hello Andy. Where can I get the extra exhaust pipe. My new heater only has 2 feet((
here is a link for you:

Is this feasible to heat water and store water for a shower? I’m reading it might be best to use heat exchanger for separate water tank?
yes
that would be a good idea
cheers andy
That water looks fucking hot Andy nice job
yes
thanks a lot dean
have a great day andy
@@andyfireblade You too man
Did that quiet fuel pump not work out ? Ticking away in background. Did you put the loud one back on ? Or did the quiet one become non quiet?? Need to know please 🙏🏼
hello larry. the quiet pump was great and then it went noisy.
i dont know why?.
the old one is in this heater at the moment.
and i am looking into it. got a few plans.
maybe me using kerosene, that is slightly thinner?
kind regards andy
@@andyfireblade thank you brother for replying. I watch a few van life channels and they all complain about that clicking while trying to sleep. It’s funny what some do to try and silence it. Do a video wrapping it In foam or something. Encase it in a ball of spray foam 🤣🤣 would be funny
@@larryferd1510 we all think alike dont we. i just had some materials arrive in the post for wrapping the pump!
the foam is one that i havent heard, but yeah. vid to come... hahaha cheers andy
I've never seen another controller that beeps like yours does
hello my friend
this was because i changed the settings a few times, thats all.
thanks for watching my friend.
cheers andy
th-cam.com/channels/3sYHaAZtJI-vrD64K7Qe9w.html
no need for pump in open application like yours , thermosiphon will do the job nicely :) also your laser probe if you pointing it at shinny objects your reading will not be correct .. like measuring water temp when probe said 22 degree iam pretty sure it was double that at least
thanks for comments cheers andy
The temperature gun won't work properly on reflective/shiny surfaces need to add some black tape or paint for best results
thanks
is it possible that the heat exchanger has a small leak in it which is causing the steam outside?
yes, good point
you probably right!
this is why i love the comms.
i would never have thought of that!
cheers andy
th-cam.com/channels/3sYHaAZtJI-vrD64K7Qe9w.html
@@andyfireblade As previous comment - not very likely!
Can I just ask where did you get the new vent? Great videos cheers
And is it any different running on kerosene to red diesel?
amzn.to/3JgGPiQ
thanks my friend
kind regards andy
@@ianarmitage3518 Yes, less heat per unit volume of fuel. Not a lot - and likely a lot cheaper on 28s kero. Less pump lube from kero, but many have run their heaters, on kero, for literally thousands of hours with no pump problems. All pumps are not equal, of course.
Just put a big coat on... im fine lol
You do know that's how a radiator works by heating water up. So was obvious it works 🤦🏻♂️
hello my friend
thanks for looking in.
yes, just had to try it this way , as i am putting a small set up in the shed, for hot water.
and you know things work in theory, but you cant beat seeing the real effects and consequences. and in doing this i have had some brilliant comments and ideas for my new shed tank.
kindest regards andy
I'm curious why didn't you take the heat directly from the copper pipe rather than going through the heat exchanger.
Simply coil the pipe and immerse it in the tank to get direct heat off the exhaust pipe.
i did a similar thing in another experiment.
thanks for your comment andy
you will be the reason why someone can't repair they ford galaxy
oh no, now i feel bad.
hahahahah
