This video details how to make a super-efficient water heater thermo siphoning process. Not only are all the parts he uses cheap or free discards, the project does not need electricity or solar power.
To match this video you will need:
Copper Tubing
Stove Pipe
Water heater
Valves
And of course, water and something to burn.
See the process video after the break and then get started on your own source of endless hot water:
there’s another one with coils of black pvc hose. have ;you seen the heater made from coke cans and copper tube? it does water and air.
What’s your “off grid” water source?
You can do this without fire as well.
AWESOME
You can do that with a small tank inside your wood stove only count on one shower every 3 hours we had a set up to pre heat the water before it went in the hot water heater seems to be most efficient and user friendly no one wants to have to stoke a fire in bathrobe tank worked better than copper
If you really want to get off the grid, buy a steam boiler, set it up with automatic controls, and use it to power a turbogenerator. Use the “waste” heat from the turbine exhaust for heat, hot water, and even steam absorption A/C in summer. As long as you have firewood (or better yet, wood chips- easier to harvest and can be fed automatically) you have your own power company. Unfortunately, when I run the numbers, when you add up all the capital costs and amortize them over the life of the boiler and the rest of the hardware, it still costs less to buy electricity than to generate it yourself. 🙁
Wait a minute, are you telling me we can heat water with….fire? Inform the masses!
Needs a small recycling pump to make it more efficient.
It’s not really endless if you have to keep stoking a fire though, is it?
unless you kept stoking the fire endlessly.
