- Using Waste Exhaust Gases to Store Heat Energy and make use of wasted exhaust gas heat. This heat would have been wasted. Off Grid Life. PLEASE COMMENT, HOW CAN WE TAKE THIS FURTHER?
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.....

Hi Andy, great idea, perhaps using a large truck radiator as the exhaust gas heat catcher and use the fan to push radiant hot air out of the core also using the rads own tap at the bottom to drain off any moisture from the inside.
A spiral tube creates less turbulence. They should sell something like this as an accessory. Several could be daisy-chained together to heat bigger garages. Great improvement in heat conservation - especially the sand idea!
yes! spiral tube sounds good.
i need to do another experiment.
thanks cheers andy
good idea, using exhaust gases as extre heat
thanks for your comment andy
Hi Andy we bought one after watching your videos
Thanks
brilliant good luck andy
We run the exhaust into our wood burning boiler and it gives some heat to our underfloor heating .also all of the diesel is free and the power is from our solar
Hi Andy.
I do store heat in sand, when I produce too much solar, the energy is diverted into a french fries coocker, the sand replacing the coocking oil. Its a 230V appliance, but I feed with 28V in, so, the température can not rise much, about 85C° after 8 hours it is still at about 40C° , it’s nice like the beach in the sun. 😄
For your gaz bottle, the goal is to exchange as much energy as possible inside, i suggest pushing as much exaust tube as manageable in a spiral or coil or any shape it would take. Pass the tube thru in out before, so no gases go in the bottle. Fill with sand from the top, leave a breather hole, if vapor is produced from moisture in the sand.
Cheers.
thats a great idea thanks, i will look into it
cheers andy
Re my earlier comment about the paint. Maybe use VHT (very high temperature) paint in a matt finish.
The flat top is a novel idea. Not too sure how well it would work but it's always worth a try. You need to cut the top off anyway to fill it with sand. Maybe don't weld it on to start with and even just place the coffee pot on top of the sand.
How about topping the last 3inches off with black sand for better thermo efficiency.
Keep up the great content Andy. This stuff is not only informative and interesting. It is also very entertaining.
Always remember:-
Necessity is the mother of all inventions.

If your outlet pipe was near the top of the tank you would get more heat out of the tank. The tank will likely fill with condensation so you should probably have a drain.

With regards to danger, at school in the 90s British gas did a demonstration. They had a treacle can with a hole in both ends sat on top of a Bunsen burner. They lit the flame on the lid hole and after a while the lid is blown off with a loud bang. I would avoid this setup for the reason if the heater fails it could potentially fill the red hot gas bottle with an explosive mixture resulting in a huge bang due to the strength of the metal cannister. Maybe this is far fetched but still. A sand battery would be a better hugely safer idea. 👍😎
good tip. thanks andy
Andy that gas bottle would make an ideal sand battery cut the top off that bottle then coil exhaust pipe working down exit at the bottom and then fill up with fine sand. you could weld the top that you cut off back on..
That would extract loads of heat :)
Great idea
Now you need to weld some vertical fins on it as a heat sink.
thank you for your comment did you see my other heater vids, www.youtube.com/@andyfireblade let me know what you think, cheers andy
Get another gas bottle do the same as before. don't take valve off turn it upside down and then you have a drain for the condensation. I would put the inlet at the bottom and outlet at the top as heat rises. Just a thought 👍
good idea thanks
Really been enjoying these videos 👍👌. As for utilization of the exhaust heat, I think some kind of waterbased heatexchanger would be best. If you could lead the exhaust through a coil inside that gas tank. Fill the tank with water and pump that water through a simple heat exchanger. An old radiator of some kind. The more water and size of the radiator the better. Maybe an old household water heater. Should probably step up the dimension of the pipe for the coil and on the exit side to account for the added back pressure caused by a longer exhaust pipe
thank you my friend.
yes, i agree, a water heat exchanger is a good long term method. yes, like a mini central heating system!
and a wider pipe is also the way to go.
i can feel a new video coming on.
hahhha cheers andy
Install a 12 volt fan on the top and circle the exhaust pipe all the way up to top and then open the end up
thanks for your comments.
please see the next vid.

Andy, Dunno if it has been mentioed anywhere, but the laser being reflected is just that - the light is not being absorbed by the surface - but thst laser only serves to indicate where the temperature is being measured, so nothing to do with the actual measurement. The infrared heat given off at that point, by the surface is the heat measured by the gun. The gun really needs to measure rays from a flat surface, unless calibrated for anything else.
Good point, i do need a new gun as well.
i really want one of these thermal cameras, but they are really expensive.
thanks , and thanks for looking
did your see my other heater videos
www.youtube.com/@andyfireblade
let me know what you think
cheers andy
Cut the top off, put spiral tubing (coiled), fill with sand or pea gravel, (sand is better), weld top back on (suggest putting wheels on it, or using dolly to move it around. inlet on bottom, outlet opposite side top. Tada!!
Thermal battery!
i just did this, please see my other videos
cheers andy
Maybe if you cut off the top and bottom of that gas bottle, put a coil of tube inside of it, ran the exhaust through the coil, put a fan on one end of the bottle, then blew air across the coil. It would kind of be like a forced air fan
good idea cheers andy
www.youtube.com/@andyfireblade
I think that maybe offsetting the inlet and the outlet would produce more heat in the recovery chamber.
Also if the heater unit was placed above the chamber and the exhaust was coiled inside and filled with kiln dried sand, the recovery chamber would become more effective/efficient and any exhaust contaminants would still flow/drain down and out of the exhaust.
Just one other small point:-
The chamber would be better painted in a matt finish. That way your readings will be more accurate. As you pointed out in this video. Those Lazer thermometers don't really like reflective surfaces.
🇬🇧👍😎👍🇬🇧
that sounds like a really good idea. i can feel another video coming on.
hahahahaha, cheers andy
I thought they advised the exhaust pipe to be straight so is winding it around safe?
A good vid. Any vids that can suggest ideas or.improvemeents to domestic heating and savings is a good video. We have to improvise because we have been sold out by out elites and parliament. With that in mind. Id. Offset the entry and exit pipes purely to stop the immediate flow out, allowing as much circulation as possible. Condensation over time may need to be considered, sand to allow long retension of stored heat, but above all. If it works. It works and this could ultimatley save. Good on ya
Consider a slow 12v fan to distribute ommitting heat around the area. I do with my house set up. It gets my 2nd floor 2 or 3 degres warmer using it.
Be lucky, also keep em coming, ive no tv licence so youtube is my entertainment
great! thanks for your comments
cheers andy
I fitted one of these in my kitchen, everything is fitted in 2 electrical boxes outside and only the heat is coming into the kitchen using kerosene as fuel. It cost me €20.00 a month and that's using it all day every day. My wife is so happy with it I've ordered another one for the hall which will heat most of the house as well. For anyone wanting one of these, its a great little system to have and very cheap to run. I set mine at 2.9hz for me its the best heat to fuel ratio.
that sounds great. i am happy that you are saving money.
thanks for letting us know andy
Nice one Andy 😉😉
Glad you enjoyed it, hope your well, cheers andy
Andy, firstly, take the valve off and dunk the bottles in a water butt until filled, to ensure all gas has been vented fully and then zero explosions. the gas bottles are designed to keep heat out, so you will need a heat shrink like damp sand in there , water will alllow quick movement of heat being a liquid, then will move into the sand, water would evaporate off, you can just unscrew the valves off them and put them back when water has vented off, any pressue would come out of the pressure relief valve if it gets too hot. That would leave a brilliant heat. Also put a solid exhaust pipe through the cylinder to get a quicker transfer of heat through the cylinder from direct metal contact, hot gases which are instantly cooled by touching the thin metal of the cylinder are not efficient, the exhaust close to the heater is hotter so move the battery towards the heater! Pipe wise ideally around a 30 degree angle. In the shoulder and through the bottom half. Like a javelin having been thrown to maximise the straight line internal surface... use the heater itself to heat the cylinder from turn on to maximise the initial warmth and temperature gradient difference... i think thats it 🤣👍
Use it like a bong😊
thats a great comment, thanks. i will look into it
thanks steven
The condensate will be collecting in that bottle if that pipe isn't coiled inside.
Of course best if the entry point is at the top and exits at the bottom so the condensate doesn't collect.
Of course as with my point about the sand battery, you could detach it and move that some else.
You'd want that bottle filled all the way up with sand.. :)
Loving this :)
i think i need to do this.
great ideas
cheers andy
@@andyfireblade Hahaha yes you do so I can get to see it ;)
Put the heater up so the exhaust runs down hill, inlet in the bottle higher than the outlet, this will allow the corrosive condensate to run off..
i will do that thanks andy
You could also cut the top off and put a spiral inside and fill it full of kiln dried sand so it should keep warm for hours
thanks for your comments.
please see the next vid, i did exactly that!!!!
www.youtube.com/@andyfireblade
cheers andy
I would have put the exhaust from the burner into the top of the cylinder
100% agree with previous comments .
If you have a length of exhaust tube formed into a spiral .
Heat in the bottom . Out a few inches from the top .
Fill with dry sand . Probably best if tube is 1 to 2 inches from sides of bottle .
Possibly cut top off to allow internal construction and initial filling .
Yes you could fit a plate for a cuppa etc .
The Scandinavians can’t remember which .
Are heating a whole village with a solar powered Sand Battery .
They are getting internal temps of 500c plus .
Wish I could remember where I saw it .
He ho old head haha .
please see my next video, thats what i did!
hahahaha

cheers andy
cut top off, insulate around the body, coil exhaust gas in body from top to bottom, fill body with sand, top will rad heat for hrs after heater is off
that sounds a really good idea. cheers andy
good experiment, as heat rises, a taller gas bottle would trap more of the heat, a piece of 100mm box section, flu from heater would be around six inches from the bottom and flu outlet out of the very bottom of the box section, capped at both ends, flu gases would slow down as they enter the larger box section, allowing the heat to rise and collect at the top, maybe add some heat sinks at high level.. keep up the experiments, a lot of heat is lost out of that exhaust..
great ideas, thanks for watching my friend
cheers andy
Andy, absolutely love your videos, informative and entertaining, thank you. It's the sort of stuff i would be doing if i had time.
Do you have a favourite method yet from the various ways you have tried to take exhaust heat?
I think this looks promising, but a safer and interesting way would be the coiled pipe in sand inside the bottle. My only concern would be the back pressure on the exhaust from a much longer pipe. Maybe time to invest in a wider bore exhaust pipe, at least for part of the exhaust exit.
Cheers
Andy Cz.
hello andy, thanks for your comments. yes, i have fun playing around with things like this. hahahaha. for good results, i found that putting the exhaust gases through a household radiator was best , but not long term. using a heat exchanger was better long term, but not as hot.
your idea is good , i might try it out. and a wider bore would help too.
thanks a lot my friend
cheers andy
thanks for watching andy
Great idea but. I think you should have the exhaust at an angle in the bottle. So that the exhaust gases can spin around in the bottle
brilliant! thanks andy
copper hot water tank and run exhuast throgh one of the heat excange loops plenty of hot water
thank you andy
The sand idea was next level 13:18 SUBSCRIBED !! ^_^
hahahah, thank you andy
You'd be better off putting the exhaust pipe going through the bottle with an upward "n" bend in it and fill the bottle with sand and then the sand would hold the heat for hours.
please see the new vid! i have done this....

cheers andy xx
Andy... great experiments... why don't you try using an old indirect water cylinder ? putting the exhaust through the primary circuit (where the boiler would have gone). The volume of water heated would be quite large and the SHC of water is very high... would stay warm for ages... slowly giving out it's heat. The higher primary connection being IN and the lower one being OUT so that the condensate can drain away.
Acidic condensate on copper ?? Well... it's not supposed to last forever...
Great idea, i will look out for one thanks andy
IMO heater itself should store that heat; why not redirect the gasses to the burn chamber until they are cool enough to be unusable? The only downside I see is that glow plug would need reheating
good point, thanks andy
try wood in it to make a wood gasifier
thanks for your comments.
please see the next vid.

Looks like your heatgun gives bad readings, if the bottle is 30 celsius it must be easy to place youre hand on the botlle. And for you its hard/to hot to touch it.
maybe, i will have to try a new one.
thanks andy
has anyone considered the all aluminum automotive heater cores ? They're fairly cheap and a 12v computer fan or any kind of fan would be fairly efficent I would think.
thanks for your comment.

Have you thought about keeping the silencer/muffler inside the room,exit pipe ouside through the wall.
You could add a thermo-electric fan,sat on top of the silencer,blowing heated air back over the length of the exhaust pipe.
Recirculating the rising hot air.
The cheapo silencers have a vent hole in them so they are not gas tight, the ones designed for yachts are gas tight. Be careful trying to attempt this unless you're certain the silencer is gas tight.
As @techtinkerin says... + I'd want a CO alarm too, just to make sure.
i will take a look at them.. cheers andy
Make it into a water heater I don't think I've seen anyone do that yet
i will do that thanks andy
You could use that through your central heating in your house even but you need some electricity to run the pump but I'm sure it's save a lot of money on running the heating coil in the central heating system
Have you ever used copper break line to heat a tank of water or even just hook up to mains water and a tap
yes. i did a vid with a copper break line.
please see it in my other vids.

also please see the latest video with the gas bottle
th-cam.com/video/9JljHjcjQ7g/w-d-xo.html
cheers andyx
So did you coil the exhaust in the tank or just run it through?
in this experiment the exhaust goes into the bottle where it is loose in side. and another pipe at the other side where it comes out. in another vid, i coil it around.
cheers andy
If you do it rite you could use it to heat the in floor heating..
If you do cut the top off you could coil a flex hose inside then close it back up..
If you do cut the top off you could coil a flex hose inside then close it back up..
what a great idea, i could do that thanks andy
May be if you put a metal screen around the gass bottle you get convection heat?
good idea, thanks andy
Why not use an old rediator
i did that in one of my other vids.
please take a look and tell my what you think

i put up cardboard on all my walls for insulation... the other week i woke up to 5 mice sleeping beside under the blanket with me hiding from the house cat that couldn't fit under the room door.
Are you telling porkies 😂

What is the BTUs of this heater Andy ??
i dont know the btus.
it is 8kw but many say these heaters are really only 5kw?
cheers andy
Thanks, Andy. @@andyfireblade
Sand and water can store a LOT of heat for weeks. If you could build a big tank with moist Sand, pipe a spiral of exhaust through then pipe a spiral of copper pipe through (ghetto heat exchanger) you could have a heat battery which you could claim the heat on demand (by pumping water through copper into a radiator )
I watched a TH-cam video about geothermal heat storage at a midwest U.S. university and they said the heat captured in the summer was stored underground and it lasted almost all winter. I still have trouble believing this. One would think the heat would quickly dissipate through the surrounding soil.
@DouggieDinosaur yeah I think there are a lot of fantastical claims out there. sand is a a good insulator which makes it good at "blocking" then absorbing energy before it heats up.
Being a good insulator means that a layer of cool sand will insulate a layer of hot sand. So theoretically, if the hot sand was buried deep enough it could retain the heat for a long time( my guess a month max?)
The problem is retrieving the stored energy from sand. Which is why I mentioned moist sand to allow phase change to help heat transfer.
good idea, i can see another experiment coming on hahahahaa
cheers andy
Where you buying the kerosene from mate?
hello my friend
hope you are well.

Cut the top off and fill with bricks like an electric storage heater, it might retain the heat longer..
good idea, yes.
thanks andy
How about filling with sand
yes, i am going to do it
