、フロアパネルが暖まりにくい欠点があった。However, when combustion gas is passed through a water heating heat exchanger, the exhaust gas temperature drops significantly compared to when it is passed through an air heating heat exchanger, and the exhaust gas condenses inside the exhaust pipe and supply/exhaust stack. There was a fear that it would freeze. For this reason, the amount of heat exchanged by the water heating heat exchanger must be reduced so that the exhaust gas temperature does not drop too much, and although the room temperature tends to rise, there is a drawback that it is difficult to warm the floor panel.

増加させつつ、排気ガス温度の低下を防止できる。(*) Effect In the heating device according to claim 1, heat radiation in the combustion gas header is reduced, and the temperature of the combustion gas flowing from the combustion gas header to the water heating heat exchanger is increased accordingly. Since the amount of heat exchanged by the water heating heat exchanger is proportional to the difference in temperature between the combustion gas temperature and the water temperature, it is possible to prevent a decrease in exhaust gas temperature while increasing the amount of heat exchanged by the increase in combustion gas temperature.

The heat exchange amount of a water heating heat exchanger is proportional to the heat transmission coefficient, so
By increasing the heat transmission coefficient, the amount of heat exchange can be increased and a decrease in exhaust gas temperature can be prevented.
