Compost pile heater
The Compost pile heater is one of several types of a compost heater. This one exploits the heat of a big compost heap in the garden to warm up a house. This type requires a big compost heap in the Garden, interveined with a spirally water hose. The water circulation conducts the heat to the building, where it can be fed to a heating circuit.
The compost heap must contain at least 8000 liters biomass to be able of holding a temperature during the freezing winter, allowing the thermophilic microbes to continue their work.
