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.....

I’d make the exhaust pipe about twice as big to improve exhaust flow and maintain or improve a clean burn, reducing carbon buildup.

@pepijng9164 Месяц назад

Critical thinking error here is that sand has a lower specific heat than water; about 5,2 times lower. As the exhaust doesn’t get hot enough to make sand a useful thermal storage medium, you can better make a water based system. Water can go up to 100 degrees unpressurised so to get the same energy density you’d need to heat the sand to 520 degrees. Of course this would make the system slightly more complicated as you would need a pressure release valve. Nevertheless cool build to improve on energy efficiency!

@icebluscorpion 5 месяцев назад

The sand baterry idea is a good one you should use more sand though. The more sand you use the more heat can be stored. I personally would insert a second pipe spiral where you can push through air or water to get hot air or water on demand make sure to isolated the thermal battery well to store the heat. This could be a great heat exchanger. The exhaust pipe is big enough to get easily cleaned and a thinner copper pipe with much more windings to get air through with gets enough time to get hot

@allsortsabouteverything 6 месяцев назад

Tuen the diesel heater back down to a lower setting and fill the tank last thing at night. Leave it running over night and see how well the sand battery is doing the following morning. It will take time to absorb the heat from the exhaust but the results of the heat release will suprise you. The next step would be to use the actual heater to heat one room whilst the sand battery and a small to medium sized fan would heat a second room at no significant increase in cost. Now that's what I call "free".

I imagine a draw through air intake tube through the center of the tank while it’s inverted that pulls the fresh air into the diesel heater. The additional heat removed from the sand battery will be expelled into the room increasing its total heat output. If the outside exhaust output becomes ambient I would be amazed.

Thinking about what there doing commercially. They have a huge sand battery in a silo with pipes to heat the sand, this is done by heating and circulation of air to about 800 degrees centigrade when the sand is to around 800 degrees they turn off the heating air and extract the heat slowly, distributing it to the local community to heat homes, it takes approx 4-6 months to extract the heat until the battery needs recharging again. Your next phase is to extract the heat, not to fast and not to slow. And look into expanding the battery size

@rkeantube 6 месяцев назад

yep, now to extract the heat faster from the sand , get a EGR Cooler and put a pipe with a plate attached in the middle, the pipe will draw the heat up and the fan with spread it to the room

@Volvoamazon62 6 месяцев назад

@jamminjim1208 3 месяца назад

That kinda defeats the purpose of sand. If you wanted to draw the heat off faster. Just use porpolene glycol. Heat will dissipate in an hour and would draw it off faster.. just saying. The point of sant is time delay.

@@jamminjim1208Let me be specific that my suggesting is when he wants to heat up a room quickly vs letting the battery slowly heat it up, also yes al loop of propylene glycol will work but he would need to make a water tight heating exchanging loop. My method of a pipe and plate much simpler and will still work.

@Volvoamazon62 6 месяцев назад

Remember a friend building a mansory heater (fireplace) with limestone, cement, stone. The heated pipe that normally would go outside, runs around in this mass, heating up the stone. Fires it up at max for a few hours and then it releases heat throughout the day. A bit the same as this.. Maybe an upgrade would be a mini mansory heater that can absorb hours of heat. Looks nice too.

Add a large coiled mass of 1/2" copper pipe to the sand mass. Then mount a car radiator on the wall with a fan to blow air through it. Place a small circulating pump between the one side of the copper pipe and the radiator, connect the other side of the copper pipe to the the radiator to circulate water through the sand mass and the radiator. You now have a heat exchanger to extract heat from the sand and circulate it around your shop.

@aweexplore1328 5 месяцев назад

Technically not a sand battery, more of a radiant heater. The gas bottle needs to be sealed and fully insulated, a true sand battery will also contain pipework to pass water through for creating hot water. An insulated container could hold the heat for many hours or days.

Great idea. The closer to where it comes out the better, heat is lost quickly on extended uninsulated tubing. I have a long length that I bought specifically for mine, so that it would cool enough to go out the window through a 2 x 3 with a hole in it wrapped in heat tape. It gets pretty cool by the time it gets to the window. I'll try putting the sand bin right under the heater so I can capture as much as possible. No reason to throw therms of heat outside when trying to heat inside.

@asbestomolesto 6 месяцев назад

A problem is that a 2 meter exhaust pipe offer too much resistance for the exhaust to flow freely. This change the combustion and so it can not be so good as with a short pipe. I use a bigger smooth pipe having no problems. I use a 10 cm extensible aluminium pipe because my heater is about 6 meters from any wall and I have a 10cm hole in the wall. Using a big pipe I have really no issue with the exhaust flow. Maybe you wanna try with a smooth pipe inside of the sand battery, maybe 5cm? IDK how to do that but I think a bigger pipe can really make a difference. If you wanna see my setup (very sketchy, but it works!) I have it on a playlist on my channel. It's in italian language, but since I speak very clear, the automatic subtitles work very well on my videos. Cheers! PS I subscribed!!!

You are right. There is condensation. It needs to be drained off... how about putting a chamber at the bottom of the tank before it goes upholl... then putting a pisser on a timmer? Shouldn't cause but buildup in the chamber untill after about 5m or 15 ft shouldn't be a problem... but if the piss chamber is about 4" could probably get another 10m. I need to start my own channel. The sand battery needs to be bigger... 50gal drum mabey.

@hisroyalblueness 6 месяцев назад

My hat’s off to you Andy, sand batteries are currently seen as future common battery to compliment the inconsistency of solar and wind production. The process involves using solar or wind produced electricity to heat sand to massively high temperatures and then to convert that heat to electricity when solar and / or wind aren’t producing. The key take from that is that sand holds heat very well. . . as your experiment also proves 👍

Press the start button to use the glowplug to burn all of the flooded diesel from the exhaust, chamber and it will also come out of where the fuel pipe was.

I'm considering doing something like this. What if you ran a piece of 3 or 4" aluminum duct through the middle of the bottom out the top, with the sand packed around it. The aluminum duct would absorb some of the heat from the sand, and if you pumped air through the duct with a small fan, you could transfer the heat into the room. The way you have it now, you are mostly storing the heat for later, not adding much heat to the room.

@oliver90owner 6 месяцев назад

Andy, you should really abide by the Eberspacher listed exhaust parts for your heater. Their maximum length of exhaust is 4m of 30mm diameter pipe without extra bends (ie straight pipe run). Your excessive length of 25mm exhaust will exceed the required system maximum back-pressure and thus affect the fuel combustion and possibly the warmed air flow. Result will be increased CO in the exhaust gases and possible sooting within the burner/heat exchanger. Maybe not too bad if the heater fuel and fan speed can be altered - but that is not available on many of the current controllers. Eberspscher design safe systems, but these chinese heaters are only designed with short exhaust piping (maximum 2m of 25mm pipe and 270 degrees of total bends) as they are expected to be used as parking heaters or as a simple ducted warm air supply from an outside position into the warmed area. Better to be safe, than operate in a less-than-optimal fashion.

@AquaTech225 6 месяцев назад

Pour all the sand out. Stick a 6” or so pipe down into it. Coil the exhaust back in around that 6” pipe. Than you’ll only be heating a few inches of sand around the exhaust and not a the sand within the center. So it may have the outer of the tank warmer since their would not be sand completely to the center that’s pumping heat further in. A get less condensation also. Just a guess

Thermal mass or Heat battery... JUST THE FACTS All Materials have whats called K value or thermal mass value.. Kind of or basically the inverse of R value in insulation ratings. This K value is the amount of heat that can be stored in any Material. BY the way the unit of measurement is based off of water having the thermal mass of 1. This is the standard. Numerous charts can be looked up, and referenced for verification. Water has a thermal mass of 1 as mentioned HOWEVER rock only has .2 or one fifth of the thermal storage potential of water by Weight. Rock is more dense Pea gravel has 95 pounds in a cubic foot. BUT water only weighs 63 pounds per cubic foot. This weight advantage of Rock VS the HIGHER thermal storage capacity of water Results in WATER stores 3.26 times more heat per cubic foot than pea gravel. Even HEAVY dense stone solid Marble is only 150 pounds a cubic foot and STILL does not beat water for BTU storage. It takes about 1340 BTU to heat one gallon of water from 40 degrees F to 200 F That means a 55 gallon drum of water heated to 200 would let off about 77,000 BTU's of heat before it went back down to 40 F. To get the same heat storage you would need to heat Four 55 drums full of stone to store the same amount of heat

@@andyfireblade Upon further research, heating fluids with the sand is far too much trouble and requires specialized glycols and whatnot. Not very practical so forget that idea.

One could take a 5 gal METAL bucket (19L for the non Americans) or perhaps even smaller metal container, run the coiled exhaust through it, fill with sand, then bury a bunch of copper or aluminum pipes (or any metal sheets) in the center of the bucket so that it sticks out a foot or so above the sand. The metal moves heat out of the sand bucket into the air.

Excellent work Andy and so quick to get it all setup. My thoughts are... The coiled pipe was close to the edge of the bottle so would lose some heat to the bottle skin, deeper in the bottle might be better, but bending those pipes with tight curves is not easy. Looking at it another way, it's partly slow release and partly instant heat, which can't be bad. There was a mention somewhere else about using salt rather than sand which they said stores more heat, but getting salt in that quantity is not easy. I wonder if there is anything better than sand? Stoney sand for example, big stones, small stones etc. I think the ultimate would be finding a way to heat the hot water in the house, therefore saving even more money. Keep up the excellent work, i actually look forward to seeing what you have done next 😊 Andy Cz.

If you want to try to heat up some water, Go out to a marine junkyard, and find a small 6 or 10 gallon electric marine hot water tank.... they have an inner heat exchanger built into them, so that while you're underway running the boat it uses the engines water recirculation pump to pump hot water through the water heater thus heating up the house water inside the water heater. So, instead of hoses circulating hot water through the heat exchanger, you could pipe the exhaust from your diesel heater through it to heat up the tanks water! Add some piping from your houses hot water system and a recirculation pump and you could possibly lower your hot water energy bill. The only question would be if the exhaust would fill up with condensate inside the heat exchanger and error out your heater. Also if the heat exchanger fails and starts leaking CO2 into the water.

This works on a similar principle as a rocket Mass stove. Where excess heat is run through a thermal mass to help increase the efficiency.

yes this is true. you are right. did you see my other heater vids, www.youtube.com/@andyfireblade let me know what you think, cheers andy

@stevecole9674 6 месяцев назад

I think what youve made there is a sand radiator. If the gas bottle was fully insulated it would get a lot hotter and the heat would be stored to use elsewhere .

You shuld reduce the pump speed, because the exhurst gases are already contain carbon. That wil cloak up your burner

I like your sand battery, but you need a way to recover the heat from the sand.May I suggest using finned copper tube from electric/fluid baseboard heaters, or you can buy the aluminum fins and slide them on. The problem is they are 3/4" and you need 1", but you still might be able to use. You will then be using the radiant immediate heat instead of storage, which i believe you would have to supplement anyway

Under floor heating next take a long time to heat the sand up but a long time to cool down to.

if you could put a copper or stainless steel coil into the sand and produce boiling water as well??

@michaelmcguigan1908 6 месяцев назад

I wonder what it would be like if you could coil up more pipe inside tight then pour sand inside the gaps would this increase the heat temperature 15:36

@egonmarder9168 5 месяцев назад

Good video! But you could have measured the temperature of the tube entering the balloon and the temperature of the tube immediately leaving the balloon. Then it would be good to understand how much the balloon stores in itself. I also believe that it would be a better solution if the turns of the exhaust pipe were smaller in diameter, then the pipe inside the balloon would be completely surrounded by sand. Just little thoughts

@funnyminky 6 месяцев назад

Brilliant work - the sand is storing the heat well, this would be an advantage if you were to combine a water storage system that then pumps the hot water into a radiator on the wall?

@andyfireblade 6 месяцев назад

@Ghostdog4 6 месяцев назад

I'd put the input on the bottom and let the heat from the hottest section exhaust pipe heat travel through more sand as it rises. I know nothing about thermodynamics and no doubt what I'm suggesting will probably result in a raging inferno or death by asphyxiation. I'm betting a clever man has already figured out how to extract every possible BTU out of this. Help me out because I think I like this design and will soon be making one

@JonathanNagy 6 месяцев назад

The exhaust needs to slope downward, or moisture will collect in it, and it will plug.

@ardennielsen3761 6 месяцев назад

if one had a refrigeration compressor system, that could be modified to heat the refrigerant creating a pressure side and with the associated valving and purge canisters and compressor it could be used for generating a small amount of electricity off the exhaust heat with a modified compressor motor now turbine generator in the cold side loop spun by the exhausting hot side refrigerant. re-engineered smoke stack? 20 to 50 degrees... cant do that with a water based system but the R12/R14 has a very good range in its boiling point. some geo-thermal power stations may be able to do the same thing...

@icabobcrane8984 4 дня назад

How about making a heat exchanger with the flexible exhaust pipe, and put a box fan behind the exhaust pipe heat exchanger. Bend the exhaust pipe in a zig zag ,from top to bottom, pipe in exhaust from the top and them out the bottom ,like the radiator you had and put a box fan behind to blow the heat into the room .

I tried putting a large diameter copper coil over an outdoor fire, trying to use the warm air from the coil to heat my tent. The condensation on the coil was so bad that it put out the fire.

put a pipe up the middle with a fan and use it as a heater ...

@unmanaged 5 месяцев назад

also see what the savings are for running heat a different times see how little you can run the heater and still get a longer run out of the sand ... when does the sand equalize and does running the heater at different speeds matter.

@Tinman6354ty 5 месяцев назад

You need the coil to be in the middle of the cylinder as you are heating the external surface and heat transfer to the central part of the sand is distant...

Hi Andy, no issues with back pressure ? I know only a tiny bit about those heaters. Running one in my wooden shed the last 18 months. Really toying with the idea of a sand battery or radiator ideas.

i would recommend the radiator way. the results are a lot better. cheers andy

@SuperHaptics 6 месяцев назад

How about soaking the sand with oil. Assuming you are not leaking oil out of the container, that would probably increase the heat transfer a considerable amount. From pipe to sand and from sand to the tank walls.
