Free Hot Water from Compost Wheelie Bin - The Permaculture Research Institute
This is a very cool method of making hot water post-apocalypse. “What I have made is a compost heater, inside a wheelie bin...A few years ago I helped build a large compost heap that had about 300 meters of 25mm rural pipe going through it. After 4 weeks this system was providing enough hot water for 35 people to wash up and shower with. I was there for 3 months and we kept adding compost onto the heap and it worked the whole time I was there."
