Compost heated shower

Wilbur:
Not sure the best location for this thread but this story was pretty interesting about the simplicity of an alternative heat source for hot water, in this case for a shower. But I also think this could easily be adopted for hot water for a cabin, a shop or any off grid method. I think with more piping it could be used as a type of radiant heat source for a building although that woukd abviously require more piping and is a different system. Plus you would need to "shut it off" during the summer.

This is really simple- hook a water source through a hose to plastic piping that gets run in a serpentine fashion through a compost "pile". In this case it's about 8' x 5'. The guy in the article starts it with a pickup truck load of wood chips and another of sawdust. Obviously any yard scraps would work- grass clippings, hay, food waste etc.

Surprisingly this guy uses it to heat water for a hostel for 10 ppl a day so if this is for an off-grid cabin or BO location that would give you plenty of water for a variety of sources beyond just showers. It gets hot enough for him (120 to 150 degrees) that he needs to mix cold water with it.

Like a lot of these things you may not do exactly what this guy did but it might stimulate you to come up with a version that works for you. Oh....and always....YMMV ha!

Here's the link to the article that stimulated this:

Don I was thinking about your hide site as a possible place something like this could be put in and used pretty effectively. And you make your own sawdust and wood chips so you have the feedstock already.

That is awesome. Why haven't we heard of this before now!!
