Next, a conventional operation sequence is shown in FIG.
This will be described using 6. When the operation is started by the indoor unit 8, the temperature of the hot water is set according to the room temperature t detected by the room temperature thermistor 11, as shown in FIG. α,
β is a determination value for determining the room temperature t detected by the room temperature thermistor 11. When the room temperature is t <α, the set temperature of the hot water is set to a high temperature, and the hot water of high temperature is generated in the outdoor unit 1,
Since the circulation pump 5 conveys the hot water to the radiator 10 of the indoor unit 8 through the hot water flow path 7a, the warm air blown to the front of the device by the blower fan 9 becomes a high temperature to warm the room. Further, since the outdoor unit 1 produces high-temperature hot water, the combustion unit 6 consumes a large amount of fuel. When α ≦ room temperature t ≦ β, the set temperature of the hot water is set to the medium temperature, and thus the warm air has the medium temperature. When the room temperature is t> β, the set temperature of the hot water is set to a low temperature, and thus the warm air becomes a low temperature. Further, since the outdoor unit 1 generates low-temperature hot water, less fuel is consumed in the combustion section 6 than in the high-temperature hot water.

For example, when the room temperature t <15 ° C., if the temperature of the hot water is set to 80 ° C., the hot air will be about 70 ° C.
If 5 ° C ≤ room temperature t ≤ 18 ° C, set the hot water temperature to 70 ° C
If the room temperature t> 18 ° C., the hot air will be about 60 ° C., and if the hot water temperature is set to 60 ° C., the hot air will be about 50 ° C. Thus, when the room temperature t is low and the heating capacity is required, the temperature of the hot air is increased to increase the heating capacity, and when the room temperature t is high and the heating capacity is not required so much, the temperature of the warm air is decreased to perform the heating. The heating efficiency is improved by keeping the capacity low.

On the other hand, as shown in FIG. 6, the room temperature control by warm air heating of the indoor unit is such that when the temperature is lower than a preset temperature T which is arbitrarily set by a certain value (for example, 1 ° C. or more), strong air is blown and the room temperature is The air flow rate is controlled such that medium air flow is performed up to a temperature higher than the set temperature T, weak air flow is performed when the temperature is higher than the set temperature T, and air blowing is stopped when the temperature is higher than the set temperature T by a certain value (for example, 2 ° C.). This keeps the room temperature at the set temperature.

FIG. 7 is a diagram showing the flow of warm air in a conventional hot water heating device. The same parts described in FIG. 3 are designated by the same reference numerals and the description thereof will be omitted. Reference numeral 30 denotes a flow of warm air during strong blowing, and since the amount of air is large, the temperature of the warm air becomes low and reaches a relatively long distance. 31 is the flow of warm air during medium ventilation,
Since the air volume is a little large, the temperature of the warm air is a little low and hits the floor directly. Reference numeral 32 denotes the flow of warm air when the air is weakly blown, and since the air volume is small, the temperature of the warm air rises and immediately rises.

However, in such a conventional hot water heating apparatus, the heating efficiency is improved by changing the set temperature of hot water according to the room temperature, but when the room temperature becomes high. Since the set temperature of hot water is set low regardless of the set temperature of room temperature and the heating capacity is kept low, when the set temperature of room temperature is set high and heating is performed in a large room, the heating capacity becomes insufficient. Had a problem that it did not reach the set temperature and the room did not warm up.

For example, the set temperature of the hot water temperature is 80 ° C. when room temperature t <15 ° C., and 15 ° C. ≦ room temperature t according to the room temperature t.
70 ° C for ≤18 ° C, 60 for room temperature t> 18 ° C
Set to ° C. If you set the room temperature to 25 ℃ and heat it in a room with a size of 16 tatami mats, the room temperature will be 18 ℃.
Until room temperature t rises, the room temperature t rises to 19 ° C or higher and room temperature t reaches room temperature.
Since the set temperature of the hot water temperature is set to 60 ° C. even though the temperature does not reach ℃, the heating capacity is insufficient and the room temperature t does not reach the set temperature of 25 ° C., and the room is not warmed.

Further, when the room temperature is low, the set temperature of the hot water is set to be high irrespective of the amount of air blown, so that the temperature of the hot air is high during the air blow, and the warm air directly hits the floor surface, so that the floor surface is dried. There was also a problem that it might crack or be deformed.

When that is not right, it transfers to step S23 and sets the temperature setting of hot water to high temperature (for example, 80 degreeC) (step S23). Step S24 detects the temperature of the hot water with the hot water thermistor 3,
The combustion unit 6 is controlled so as to reach the set hot water temperature, and the hot water temperature is controlled to be constant. When the room temperature t ≧ α in step S22, the process proceeds to step S25, where the room temperature t ≦ β (α <
In the case of β), move to the next step. Step S30
Determines whether the amount of air blown by the blower fan 9 of the indoor unit 8 is medium air blow. When the air blowing amount of the air blowing fan 9 is medium air blowing, the process proceeds to steps S29 and S24. When that is not right, it transfers to step S27, 24. Room temperature t> in step S25
In the case of β, the process proceeds to step S29 and the temperature of hot water is set to a low temperature.
