温水式暖房装置

Hot water type heating device

Abstract

PURPOSE:To prevent the overheating of an indoor heat exchanger by actuating a heating means in conformity with the operation of a floor heater when it is necessary to supply hot water heated by the heating means to both the indoor heat exchanger and the floor heater and on/off controlling a fan for a longer on-state operation time than when the hot water is supplied to the indoor heat exchanger alone. CONSTITUTION:A control circuit 7 picks up a room temperature on a room temperature sensor 74 and compares the temperature with a setting room temperature set by a room temperature setting instrument 75. When a floor heating switch 73 is turned off at a temperature which exceeds the setting room temperature and a solenoid valve 55 cuts off a hot water supply passage to a floor heater 52, a gas burner 6 and a convection fan 3 are controlled in repeated on/off mode. When the floor switch 73 is turned on and the solenoid valve 55 supplies hot water to the floor heater 52 as well, the gas burner 6 is actuated in response to the operation of the floor heater 52 while the convection fan 3 is on/off controlled for an on-state operation time longer than when only an indoor heat exchanger 51 is operated. It is, therefore, possible to inhibit a rise in the temperature of the indoor heat exchanger 51 and bring the surrounding temperature of the room temperature sensor 74 near the room temperature.
