Abstract: PURPOSE:To prevent overheating of a housing by stopping the electric current supplied to a heater when the temperature of a thermal storage block exceeds a certain temperature and blowing air to the thermal storage block by activating a fan. CONSTITUTION:A thermal storage type space heater 10 is constituted of a thermal storage block 12, heater 14 to heat this thermal storage block 12, fan 16 that generates hot air by blowing air to the thermal storage block 12, and overheating prevention device 18. Heat is stored by heating the thermal storage block 12 by supplying electric current to a heater 14 with the midnight electric power zone utilized. And, the temperature of the thermal storage block 12 is monitored by a thermistor and when its temperature is over a specified temperature, an over-heating prevention device 18 activates a fan 16. With this arrangement air is sent to the thermal storage block 12 and the heat of the thermal storage block 12 is forcibly radiated to the outside air. An abnormal rise of temperature of a housing 22 is thus prevented.
