Abstract: A forced air range is part of a domestic appliance system which includes hot and cold thermal reservoirs. A thermal exchange fluid can circulate between a heat exchanger in one of the thermal reservoirs and a heat exchanger within a duct in the forced air range. For operation, an ordinary houseware such as a pot, is placed on the range and temperature and heating rates are programmed. A blower circulates air through the heat exchanger and under the houseware. Thermal exchange fluid flows through the heat exchanger to maintain the circulating air at the programmed temperature.
