On the other hand, a fan convector 7 is installed in the room, and a first going pipe 5 and a return pipe 6 can circulate and supply hot water through the hot water outlet 10 between the fan convector 7 and the boiler 2. It is arranged in. Further, a controller 3 is attached to the fan control vector 7.

A hot water heating floor 15 is installed in the room, and between the hot water heating floor 15 and the boiler 2, a second outgoing pipe 12 and a return pipe 13 supply hot water through a hot water outlet 11. It is arranged so that it can be circulated. Further, a controller 4 is provided near the hot water heating floor 15.

By the way, a hot water temperature controller 17 is provided in the middle of the circulation path of the hot water heating floor 15, and
5 to the temperature of the boiler 2 (for example, 8
0 ° C) or less (for example, 40 to 60 ° C). That is, the hot water temperature controller 17 includes a mixing valve 19 such as a three-way valve.
The first inlet is connected to the upstream portion of the access pipe 12, and the outlet thereof is connected to the downstream portion of the access pipe 12. A bypass pipe 14 is connected to the second inlet of the mixing valve 19 so as to communicate with the return pipe 13, and a pump 20 is attached to the bypass pipe 14. And the mixing valve 19
By appropriately adjusting the opening / closing degree of the second inlet and driving the pump 20, a part of the hot water returning from the hot water heating floor 15 to the return pipe 13 is guided to the mixing valve 19 via the bypass pipe 14.

A thermistor 16 is attached to the outflow pipe 12 near the outlet of the mixing valve 19, and the temperature of the hot water mixed by the mixing valve 19 and supplied to the hot water heating floor 15 can be detected by the thermistor 16.

The boiler 2 is provided with a board slide switch 18.
, The set temperature of the hot water heating floor 15 can be set in two stages (for example, 60 degrees) according to the user's preference and the heating environment.
° C and 70 ° C).

Further, as shown in FIG. 2, a main control unit 21 such as a microcomputer is incorporated in the hot water type heating equipment 1, and the main control unit 21 has the controllers 3, 4 on its input side. The thermistor 16 and the substrate slide switch 18 are connected to the mixing valve 19 and the pump 20 on the output side.

Since the hot-water type heating equipment 1 according to the present invention has the above-described configuration, when heating with the hot-water type heating equipment 1, the main control unit 21 uses the heating operation program PRG shown in FIG. , Heating is performed on one or both of the fan convector 7 and the hot water heating floor 15 in response to an operation command from the controllers 3 and 4. Here, the case where the set temperature of the hot water heating floor 15 is set to 60 ° C. by the board slide switch 18 will be described, but the same applies to the case where the set temperature is 70 ° C.

N, it is determined whether the operation command is not ON (it is OFF), and if it is determined that the operation command from the controller 3 is ON, the process proceeds to step S2 of the heating operation program PRG. Is determined. as a result,
When it is determined that the operation command is not ON (OFF), it is determined that there is no intention to use either the hot water heating floor 15 or the fan convector 7, and circulation of the hot water is not performed. Conversely, when it is determined that the operation command from the controller 3 is ON, the heating is started only with the fan convector 7, so that the heating operation program PRG is executed in step S
3 and after setting the hot water temperature of boiler 2 to 80 ° C,
In step S4 of the heating operation program PRG, the boiler 2
To the fan convector 7 via the outgoing pipe 5 and the return pipe 6. Then, the heating operation is started by the fan control vector 7, and the room is warmed. At this time, the temperature of the hot water circulated and supplied to the fan convector 7 is 80 ° C., so that the fan con vector 7 can sufficiently warm the room.

On the other hand, if the result of determination in step S1 of the heating operation program PRG is that the operation command from the controller 4 is ON, the process enters step S5 of the heating operation program PRG and the operation from the controller 3 is started. It is determined whether the command is ON. As a result, when it is determined that this operation command is not ON (is OFF), heating is started only with the hot water heating floor 15, so that the process enters step S6 of the heating operation program PRG and the boiler 2
After setting the hot water temperature to 60 ° C., the hot water of 60 ° C. is circulated and supplied from the boiler 2 to the hot water heating floor 15 via the going pipe 12 and the return pipe 13 in step S7 of the heating operation program PRG. Then, the heating operation is started on the hot water heating floor 15, and the room is warmed. At this time, since the temperature of the hot water circulated and supplied to the hot water heating floor 15 is 60 ° C., the room can be appropriately heated by the hot water heating floor 15.

If it is determined in step S5 of the heating operation program PRG that the operation command from the controller 3 is ON, heating is started by both the hot water heating floor 15 and the fan convector 7. Therefore, after entering the step S8 of the heating operation program PRG and setting the hot water temperature of the boiler 2 to 80 ° C., the heating operation program PRG
In step S9 of RG, the combined operation is started. Then
The heating operation is started by the hot water heating floor 15 and the fan convector 7, and the room is warmed up in a short time. At this time, the hot water temperature to the hot water heating floor 15 is reduced to 60 ° C. by using the hot water temperature controller 17. Then, the fan control vector 7 has 80 ° C
The hot water of 60 ° C. is circulated and supplied to the hot water heating floor 15 at the same time as the hot water is circulated and supplied, so that comfortable heating can be performed while preventing low-temperature burns on the hot water heating floor 15.

The heating in the hot water type heating equipment 1 is performed based on the operation command from the controllers 3 and 4 as described above. By adding various timer functions to the controllers 3 and 4, It is also possible to arbitrarily set the start time and the end time of the heating operation on the fan control vector 7 and the hot water heating floor 15.

In the above embodiment, the case where the hot water temperature controller 17 is used as the hot water temperature controller has been described. However, the hot water temperature controller is not limited to this.
For example, a heat exchanger having a predetermined heat exchange efficiency can be used as a simple type hot water temperature controller.

Further, in the above-described embodiment, the case where the fan convector 7 and the hot water heating floor 15 are employed as the hot water heater is described. However, the hot water provided with other hot water heaters (for example, a radiator panel or the like) is described. It is also possible to apply the present invention to the heating system 1.
