Wood burning stoves with good heat retention

Supplementing a soapstone fireplace with an powerstone will provide a greater output of heat for larger areas; in laboratory tests the cooling period of the stove was 12 hours with a closed damper and 8 hours with an open vent! A fan can also be added (instead of a heat tank) which will provide an additional kick of hot air and help the warmth circulate throughout the room to nearby areas.
