Free Heat from Waste Exhaust Gases Heating Radiator Home Oil Diesel Heater Chinese Recovery Exchange

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

[@robsteve7043]

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.

[@andyfireblade]

[@jim4556]

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.

[@elfillari]

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?😊

[@user-zt2hi8mq2r]

Good man, this is exactly what I have been looking for. Thanks

[@fasteddy664]

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.

[@andyfireblade]

@@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😁😁😁

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.

[@andyfireblade]

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

[@monkeynuts1268]

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.

[@andyfireblade]

great comment thank you cheers andy and happy new year

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

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.

[@allynonderdonk7577]

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.

[@andyfireblade]

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

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

[@TonyLeach-airguntech]

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.

[@NordicDan]

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.

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.

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.

the exhaust straight through got hotter. but for a long term lasting system , i would use the heat exchanger . cheers andy

[@hisroyalblueness]

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.

[@andyfireblade]

thank you my friend cheers andy xx

[@richardcooney7789]

Very good. I was wondering if you ran that exhaust pipe through a metal tank of sand if you could capture longer lasting heat .

[@andyfireblade]

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 kzbin.info/door/3sYHaAZtJI-vrD64K7Qe9w kind regards andy

[@mickgatz214]

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......

[@elbuggo]

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.

[@mickgatz214]

[@jonmorby]

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.

[@andyfireblade]

you are exactly right. i have tried this with out a pump and it works just as well. thank you for your comment did you see my other heater vids, www.youtube.com/@andyfireblade let me know what you think, cheers andy

Wonder how good using a car radiator and pumping the exhaust gases through it and have a fan behind it.

[@andyfireblade]

good idea, cheers andy

[@christopherlewis2274]

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

What if you filled the rad almost 90%full of h2o and having the pipes passing through the 2 top inlet and outlet holes?

[@roberthammock2759]

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.

[@andyfireblade]

Great idea thanks , and thanks for looking did your see my other heater videos www.youtube.com/@andyfireblade let me know what you think cheers andy

[@rabvtec999]

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

[@andyfireblade]

with hose clamps worm drive or jubilee clamp

[@XxTWMLxX]

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

[@Fish-bw9yh]

What about a car radiator? That should help with the centre cold spot and you could even mount a fan to blow into the room! Loads of 2nd hand around and I've seen a new custom built aluminium (not sure if that's a suitable material) for just £30.

[@andyfireblade]

thats a brilliant idea cheers andy

[@Will-x1]

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?

[@andyfireblade]

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. kzbin.info/www/bejne/bKO0cqJuobh_frs regards andy

[@anthonyjulson8840]

Maybe some exhaust header wrap from the parts store around the exhaust pipe on you heater. That way more heat makes it to the radiator.

[@andyfireblade]

yes, good idea kind regards andy

[@robsteve7043]

I wouldn't waste my money. The heat's radiating into the room from exhaust pipe anyway, so why wrap it unless it's for protection from burning something.

[@anthonyjulson8840]

@@robsteve7043 I kinda thought about that after the fact. You're right though.

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

[@thatscrazy4487]

I would put some computer fans at the bottom to force air upward faster so it recovers even more heat and also to not cook the paint on the radiator because those gases are toxic.

[@andyfireblade]

thanks for looking. did you see my other heater videos www.youtube.com/@andyfireblade cheers andy

[@danjason2167]

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.

[@andyfireblade]

thanks cheers andy

[@jibbyjabby7499]

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.

[@regwatson2017]

Or through sand as a sand battery - that would be even better (unless you wanted hot water). Sand can hold heat for hours.

[@andyfireblade]

yes, long term, i think thats the way to go. good comment. regards andy kzbin.info/www/bejne/bKO0cqJuobh_frs this is the other one in the house.

[@afiftwemeh8102]

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!

[@andyfireblade]

Thanks for the info!

[@alexanderwest1623]

just a thought you could use an old inter cooler as there is a lot more surface area on them and there made to cool air not let of heat from hot water

thank you my friend there are a few here, but the prices have gone up slightly. amzn.to/4a1oqkV cheers andy

[@para144]

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

[@andyfireblade]

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. kzbin.info/door/3sYHaAZtJI-vrD64K7Qe9w have a great day andy

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.

[@andyfireblade]

yes, it does give some exhaust restriction, but none leaked out where it shouldnt. did you see my other heater vids, www.youtube.com/@andyfireblade let me know what you think, cheers andy

[@unogazzy84]

@@andyfireblade Yeah but only two including this one. I'll take a look at the others ones.

[@oliver90owner]

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.

[@JohnSnow-lb6xi]

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.
