The unit ''stere'' can be used in this context directly to calculate the needed capacity of the compost heater, because the filled in biomass (for example chipped wood) contains a comparable fraction of air. 2100 kWh heat energy are, therefore, generated per m³ composting space. The residual moisture does not diminish the usable energy output and can be ignored in this case. It may vary without any impact. In contrast to a wood stove the residual moisture is not vaporized in a compost heater, so the energy conversion efficiency is not reduced. | The unit ''stere'' can be used in this context directly to calculate the needed capacity of the compost heater, because the filled in biomass (for example chipped wood) contains a comparable fraction of air. 2100 kWh heat energy are, therefore, generated per m³ composting space.

While the heating of older dwelling houses require more than 20,000 kWh per year, the recently developed well insulated houses require less than 10000 kWh. For example, the [[House in a house|House-in-a-House]] can be easily served by a compost heater silo of the size 2000 l | While the heating of older dwelling houses require more than 20,000 kWh per year, the recently developed well insulated houses require less than 10000 kWh. For example, the [[House in a house|House-in-a-House]] can be easily served by a compost heater silo of the size 2000 l, making the interior of the house comfortably warm throughout the year. | ||
