this is the last video where we don't have a microphone. all videos going forward are better audio quality. thank you!

We had baseboard heating in the house I grew up in. Copper pipe from a furnace run along the baseboard in portions of each room, encased in a 9” tall sheet metal radiator that was piped into each room., aluminum fins surrounding the pipe. This got hot to the touch. You might look around for something salvaged if you had a benefit to running the heat further from the source.

Really enjoying what you are sharing. 🎉

very cool idea. I currently am trying to utilize a sand battery. I am charging some 600watt 24v hot water heater elements with 200 watts 24v of solar throughout the day. Today is my first day. it didn't heat up like I wanted. But ur video has really made me think, definitely might get some 55gallon drums n replicate ur system, just with solar panels n some type of heater element for the sand. also solar on the pump, so during the day it'll heat it up n hopefully throughout the night it will retain the heat.

Left wing qualty aaaah sound.

Thx for your work mate ! Love y'all ❤

Protect your pipe from galvanic corrosion. Copper and ferrous metals don't play well together. The beauty of this system is in its thermal battery effect. The heat will continue to dissipate into your space long after the fire is out. THAT is why I love mine so much. There is no need to get up through the night to feed the stove.

Nice Job! My only suggestion is to insulate the bucket so your sand battery doesn't immediately send that energy to the air. I'd use a fireproof vermiculite cement mix (3verm+2sand+1cem) for the insulation as a 1" liner inside the bucket.

I hooked up a couple solar panels to a heater coil and put that in a bucket of sand and it got as hot as a wood stove. Melted my first heater coil. I think instead of sand I need to use pea gravel so it can have some dispersion of the heat.

Thanks. Im looking to build a greenhouse house heater. Same in theory but different in scope. I have a hobbit stove from a defunct school is project. It has the boiler built in. I have salvaged electric water heater tanks, using them as passive heating. After watching this im now planning to open one tank run the copper coil thru it fill it with sand then run the cooper to the water tank above it then run it back to the stove.
The only thing i would do differently if i was building with what you have is to jave the water closer to the stove otherwise fantastic build. Thank you for helping me work my build out.

Hmm this is interesting. I have a sauna where I heat the water using SS flex pipe around the flue heating a tank of water that is a few feet up in the ceiling. The water heats pretty fast when inside the sauna, unlike when I had it outside. I already tried by placing another SS flex pipe inside the hot tank which also gave me instant warm to really warm water. Now you have a cool idea here with using sand and it seems like it maybe providing even better water output. I'll have to test this, plus sand doesnt cool off as fast.

this may be what I need here in the Philippines....

Man I absolutely love what you’re doing! 🙌🏻👊🏻
Your experiments are way cool and I hope to do some of them as well!
Definitely interested in seeing more on this experiment! I’d like to know what the temp is in the morning after a night of cooling.
What is the little sensor computer board your using?
Y’all definitely should throw in some more cooking videos with that neat little oven.

If you put the barrel above the stove you could eliminate the pump and it would thermally siphon

[Really]

Those copper connections usually need a bit of welding, or they leak, often not good enough to be sealed 100%

[afishl]

Wonder if it would work better if you had the hot water return near the bottom of the barrel (cause heat rises, then the pickup at the top (so you aren't cooling your sand. The way you have it, the hot water is dumped near the top and naturally wants to stay there where you will lose that energy from the steam coming out

[bonsaitree]

Can you eliminate the pump with check valves?

[didgeridooblue]

Since sand batteries can get very hot (> 212 F), how do you go about removing heat from a sand battery that's hotter than boiling water?

[koskos]

What are you gonna do with that hot water? Heat exchanger?

[dmitriust]

Would this same style system work with a siphon, instead of the electric pump??

[nathanborders]

Tell me the source of the water pump? Maybe from Amazon?
