Compost-heated shower
Thermophilic compost heaps get hot from bacterial activity. If you coil a long, thin water pipe through compost heap, the water gets heated. The one in the video has 400 feet (122m) of 1 inch (2.5cm) thick hosepipe running through a 2m3 (70 cubic feet) compost heap. This heats water to 90°F (32°C). It stays at that temperature constantly, night and day, and the water quickly reheats after it is used. The hot water could also be used for radiators. Thermophilic compost can get up to 70°C (158°F) if air is pumped in from underneath.
