- 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.
Amazing people are sharing ideas.
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
thats a really good idea thanks.
thank you for your comment did you see my other heater vids, www.youtube.com/@andyfireblade let me know what you think, cheers andy
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".
brilliant!!!
cheers andy
@@andyfireblade on my second unit because I ran my first on low a lot and got a TON of carbon buildup. I thought it was completely broken when it quit starting one day and later learned the cause when I was swapping in the new unit.
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
Crawl space heating under a home or cottage! Keep it dry & mold free! Great job thinking out of the box! *cheers*
Great idea!
and thanks...cheers andy
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
you have some really good ideas my friend, thanks again
cheers andyxxx
Or weld some cooling fins to the outside of the bottle.
Yeah, I agree. You need to extract the heat before it gets saturated and the end pipe will heat up again.
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.
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!
this is a good idea. I have a diesel heater in my greenhouse. I could heat the sand filter up overnight with the heater on and turn the heater off during the day and just let the sand heater Keep the greenhouse warm during the day over the winter months. Definitely worth doing 👍
That's a great idea!
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!!!
brilliant thanks.
yes you are spot on, smoother pipe and bigger is the way to go
cheers andy
Hi guys.
Instead of a bigger pipe, 2 standart pipes or more in paralell would give more surface area to exange heat with the sand.
Cheers.
Your some man for one man Andy, loving your interesting videos, thank you.
Much appreciated, thanks for looking andy xxx
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.
sound good cheers andy
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.
sounds good , great comment thanks andy
I agree with this ! I had the exact same thought then seen somebody already commented it !
That sounds nice and simple and cheap.
Just remember a pressure relief valve incase the radiator coolant overheats from the sand
@@chrisdick9860 I as well! Similar idea. Wrap copper tubing around the exhaust. I wonder if it would be hot enough to get a thermosyphon going. Running it into a car rad will give you the ability to use the rad cap as a pressure blowoff if it got to hot. Rad fan on reverse to pull the heat off the rad into shop.
I have always thought the best idea for these is the EGR cooler to heat water, then to run that to an independent radiator. but the nutty professor in me has always though…. Boil water using the exhaust gas… to create steam… to turn a turbine… to create electricity… to run the heater 🤣 or just charge a battery
yes the egr cooler is a great way. but that sounds a good idea too.
we are all nutty professors arnt we? hahahahahah.
but we are not hearting anyone are we? hahhahaah
cheers andy
A genius idea Andy. I shall be using it in my shipping container. Star
thanks a lot andy
Thanks 👍. I think I might try something similar with my wood burner in my garage.
bloody brilliant !! i,m thinking of using an aluminium beer keg to create similar .
i like that idea
cheers andy
The brumie accent the most friendly accent in UK imho. I Lived up there for a few years Wolverhampton to be exact Dixon Park and loved it as a scouser we both have strong accents 👍
thanks mate
Nice video Andy. I bought a dieselheater to, and will try out youre tips. Thank you and i subscribed.
Greatings from the Netherlands!
Awesome, thank you!
What about when the heater needs to go through a cooling down operation before shutting off . The sand will then get cold as the pipe will be blowing cold air back through. Only thing to do is to have two exhaust pipes one with a y piece coming off the heater with a shut off valve so you can still keep the heat in the sand !!!
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.
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
It would be nice to try to see your burner chamber after you do this test. to see if the condensation it produces causes soot to enter the burner chamber. Due to excessive resistance in the exhaust
good comment, thanks andy xxx
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.
Built mine yesterday works great
Good to hear
great cheers andy
Great going, bet stays hot for ages after the diesel heater is turned off, nice going
yes it does.

Brilliant experiment
Cmon guys give this dude a like a subscription 💪👍
Much appreciated! hahhaahahahaha

Thank you! Cheers!
Now you should put a wood stove heat generated fan on top of the sand. Spread the heat from the sand to around the room.
cheers andy
New drinking game - each time you say “you can put your hand on it”. 😂
hahhahaa, cheers frank
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 👍
great thanks for taking the time to watch my vids and comment cheers andy
Brilliant stuff from Andy once again.

I just had my diesel heater flood. Now I need to open it up and clean it out. I also bought a new one, waiting for it to arrive. Great ideas.
Good luck!
Faulty glow plug, perhaps
@@247SH no there is fire, but not enough, It also blows white smoke from the air intake and as leaking diesel from the air intake. I know it's flooded. Going to try blowing air in the air intake with no fuel and hope that it burns off the leftover fuel before I open it up.
@@andyfireblade Thanks, I need my basement heater, lol. Helps me save my boiler from cooling down too fast.
Don't strip it down. Just remove the fuel pipe that goes into the heater (the one between the air in + exhaust out) and rest the pipe in a container. 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. Do this a couple of times until the white smoke stops. The pump will also squirt the diesel into the container, so pour it back into the tank and fix the fuel pipe back where it was. It will now start as normal.
Great, now you can make a sand coffee!
hahhahaha yeah
If you added 6 or more 2” vertical stand pipes protruding through the bottom of the tank (welded) and raised the tank high enough to place a small fan underneath, with the sand poured in around the vertical pipes you could extract the heat😊
thanks for the comment cheers andy
You can also use a cast iron steam radiator for the same purpose as I have for years. It works very well with very little screwing around.
great! cheers andy
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.
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
thats a really good idea thanks andy
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.
Here is my idea :
Since you have the space against the wall..
Use a thin wall, long full length of elect conduit ,3 or 4 inches in diameter..
Use house hold tin cans for the end caps to retain
sand... get the long sand pipe off the concrete floor using some form of support ...
Bricks , or bent wire risers
thanks for your comments cheers andy
I was about to do something like this on my van diesel heater lol
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.
yes, your right and also Great idea
thanks , and thanks for looking
did your see my other heater videos

let me know what you think
cheers andy
Ok have exhaust go in bottom. Install wire that sits off bottom. Install small rocks 1/2 inch. Make this about 3 foot wide 4 ft high. Vent out top. Have pipe go through side or copper tube inside to warm water
thank you for your comment did you see my other heater vids, www.youtube.com/@andyfireblade let me know what you think, cheers andy
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.
i am listening to you my friend
good comms
good night andy xx
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.
You could buy the salt from a supermarket 😂
Take my 2 pence worth with a pinch of salt.. what about vertical troff like sand box with the exhaust running straight through about say 10" of sand .. hopefully you get my drift.. nice content as well you've convinced me to save some pennies and buy one .. cheers pal.
thank you for your comment.
thats a good idea, a couple of other people said exactly that to me.
great minds think alike!
did you see my other heater vids, www.youtube.com/@andyfireblade let me know what you think, cheers andy
Nice! I’m thinking of combining this with an old towel radiator to make a tall thin sand wall! If you have a guard for your grinder please use it! Accidents do happen. I have been very lucky so far, but grinders tend not to take prisoners when they bite 😬
ok, great idea with the towel rail, i am looking out for one or a big old cast iron radiator
thank you for your comment did you see my other heater vids, www.youtube.com/@andyfireblades let me know what you think, cheers andy
two channels , this is the other
www.youtube.com/@andyfireblade
cheers andy
@@andyfireblade yes thanks, I’ve seen a few now! Yes a cast iron rad should have a nice thermal mass and a bunch of material if the condensation/acids start to eat the insides out 😂
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 .
Add some Heat Transfer Fluid to the sand like Polyalkylene glycol (PAG) which can reach up to 260c and see what happens. Heat would transfer more efficiently and you could even run a copper coil through the oily sand to heat up water if you wished. I think this could work, especially for smaller setups like yours.
thank you for your great comment !
i will look into it.
did you see my other heater vids, www.youtube.com/@andyfireblade let me know what you think, cheers andy
@@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.
But, I was thinking of ways to improve the efficiency of this sand battery design.
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. You could even use a fan blowing over the whole thing or even better, just place that whole setup about a foot in front of the diesel heater's blower fan.
@@TheLitVic thanks a lot really good idea, i will look into it
cheers andy
I’m thinking of running exhaust through a sand filled clay drainage pipe, appreciate that doesn’t offer a compact battery but would mean exhaust run can be short/balanced and should capture and radiate some of the exhaust heat. You could always add that in line on the first part of yours I guess, steel flue would also work.
good idea cheers andy
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.

Try useing a copper coil pipe in the sand battery copper is a good heat conducter great job 🙏
good idea thanks andy
mix wax in w the sand. it will fill the gaps. act as an oil when hot. takes even longer to cool, and when cooled you can move it without spilling anything
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 .
thanks for your comments.
please see the next vid.
www.youtube.com/@andyfireblade
cheers andy
Great work! How about placing your EGR Cooler (from your previous video) directly under the heater into the exhaust then into the sand battery for hot water into a radiator and sand storage?
great idea, new vid, thanks andy xxxxxxx
It will take all night to heat the sand up fully !!
Another option would be to get you about a 6” piece of pipe. Weld it to the bottom of the tank to take up some of the center space.
Get you some 1-2” wide thin strips of any cheap 1/16” steel. Weld it vertically around the outside of the vessel.
Coil the exhaust back into it. That outer space area between both the walls. Than fill that space with water.
I haven’t looked. I wonder if theirs another liquid safe to be heated. That has a pretty high boiling point/safe to be heated/easy to acquire. That may function better than plain water would.
Or maybe some kind of blend of something
thats a good idea
cheers andy
Glycol or RV anti-freeze would be great….. possibly run through a thermal siphon to an insulated tank. Add a circulation pump and pressure relief valve for safety, then you could use this to circulate through a closed loop hydronic floor heating loop (PEX or whatever). I’m going to try this in my workshop!
Could use exhaust pipe wrap on the hot side for insulation and maybe on a trolley and quick release to take the bottle into the house in the evening
good idea, thanks for sharing.

Gave me an interesting idea for my Camper. Sand jacket around the engine exhaust pipe and have a 28mm or bigger pipe, inside the jacket with a heater blower on one end and the other end terminating inside the camper? I will think on it! Thanks.
yes , it is good to stir up new ideas, thats what i like
cheers andy
Under floor heating next take a long time to heat the sand up but a long time to cool down to.
Now make a thermal mass bench heater based on the rocket stove bench heater for off grid lots of examples on yt
use a cast iron radiator
I was going to run the exhaust pipe through clay tubing, weeping tile clay pipe.... I've heard clay can retain heat very well...

fill up the gaz bottle with water put some copper reel pipe inside the gaz bottle plumed in to a house radiator with a water circulation pump and dont forget an expansion water tank from the copper reel .
great idea , thanks mate.
andy
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
Thanks for the tip!
Once its up to temp' i'd pop the top off and put a frying pan in the sand and try and cook a fry up !
hahahaha cheers andy
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
thank you for your comment.
great idea, i will look into it.

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
The exhaust needs to slope downward, or moisture will collect in it, and it will plug.
Hot tub heater heating water 👍
Adding a high temperature ceramic coating to the outside of the exposed exhaust between the heater and the battery would also scavenge the heat within the pipe... Just a suggestion but could better heat the sand as the heat would be INSIDE TJE EXPOSED EXHAUST
great thanks andy
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.

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
Next is a stove top with a sand and brick battery all powered from the exhaust
how about running some coils in the sand and do a heat exchanger for water ...
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?
good idea thanks andy
we did a thermal mass around our wood stove. night and day. even after stove is out the thermal mass keeps warming. bigger mass longer it gives back heat.
interesting cheers
An old fire extinguisher would with its wall bracket could be useful too
yes, cheers andy
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...

Add radiator fins to the bottle
good idea cheers andy
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...
great idea, i will look into it
thanks andy
You may find it clogs up with soot/carbon I had a 2 metre exhaust under my van and where it cools down so much it was all blocked just had to strip my heater to clean it
thanks for your comments.

Sand core with water jacket outer or other way round then pipe to rad in house with a circ pump 12v via solar n battery
good idea
cheers andy
You shuld reduce the pump speed, because the exhurst gases are already contain carbon. That wil cloak up your burner
thank you for your comment did you see my other heater vids, www.youtube.com/@andyfireblade let me know what you think, cheers andy
Now you have to figure out how to get the heat in the sand to heat you 🤔 or make into millivolts 😮😮
If you turned that sand heater upside down those handles would be the base then the concrete floor wouldn’t suck the heat out of the sand 🤔🍻
true, cheers andy
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.
good idea thanks andy
It would be interesting to scale up the sand battery using a 200 litre clip top drum. Something I would try if I can make space in my "garage".
sound good!
Seen a video making one out of a old water heater tank, guy did a nice job.

Try filling with pebble stones instead of sand that would be decent experiment
are stones better?
if you could put a copper or stainless steel coil into the sand and produce boiling water as well??
Should have a guard on that angle grinder.
haahahaha, cheers andy , please check out my other channel shedhermit and see more of my vids with tools.
cheers andy
put a pipe up the middle with a fan and use it as a heater ...
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.
I think your exaust pipe might rot faster if its not drying out from the heat.
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
how about a long oxygene bottles on its side can bracket to the wall like a wall heater same coil and dry kiln sand .just a thought
good idea, shame , i just got rid of one of those!
cheers andy
The problem you have with the thermometer is they need a dull surface and not a reflective one. Take a measurement from the sand and not the container.
And immediately after typing that, you did.
