In this case, a total of about 10 to 20 complicated wiring works are required. It was necessary. In addition, if the piping and wiring do not correspond exactly one-on-one, the temperature control of each room cannot be performed accurately. Therefore, a pair tube in which two pipes for return and return and three lead wires are placed in the same sheath tube. However, there is a problem that it is easy to miswire in the hot water heat source unit where the piping and wiring from all radiators are concentrated. There was a problem that the lead wires in the pair tube were disconnected due to the difference in thermal expansion coefficient of the lead wires.

(Embodiment 1)
FIG. 1 shows a hot water heating system diagram according to Embodiment 1 of the present invention. A hot water heat source unit 1 includes a hot water heat exchanger 1b that raises the temperature of water by heat from a heating element 1a, and a pump 1c that conveys hot water. It has a heat source control unit 1d that controls the heating element 1a and the pump 1c, and a heat source side wireless transmission / reception unit 1e that operates in accordance with instructions from the heat source control unit 1d.

  Room A radiator 2 includes a heat sensitive body 2a for detecting the temperature in the room, an air heat exchanger 2b for receiving the hot water and raising the indoor air, a fan 2c for blowing the warmed air into the room, and opening and closing of the hot water. A heat radiation control unit 2e that controls the air heat exchanger 2b, the fan 2c, and the valve 2d according to information of the heat sensitive body 2a, and a heat radiation side wireless transmission / reception unit that operates according to instructions from the heat radiation control unit 2e. 2f.

  A room B radiator 3 having the same configuration as the room A radiator 2 is connected in parallel to the room A radiator 2 with respect to the hot water heat source unit 1. For example, when a user in the room A gives an operation instruction to the room A radiator 2, the heat radiation control unit 2 e opens the valve 2 d and rotates the fan 2 c, and at the same time transmits a driving instruction signal from the heat radiation side wireless transmission / reception unit 2 f by radio waves. .

  The heat source control unit 1d that has received the operation instruction signal by the heat source side wireless transmission / reception unit 1e drives the heating element 1a and starts conveying hot water by the pump 1c, and also receives the operation instruction signal and the hot water heat source unit 1 is in an operating state. A signal indicating that the signal has entered is transmitted by radio waves from the heat-source-side wireless transmission / reception unit 1e.

  When the room temperature of the room A eventually rises, the heat dissipation control unit 2e detects the increase in the room temperature with the heat sensitive body 2a and drops the output of the fan 2c, or the hot water flow rate with the valve 2d, and the heat radiation side wireless transmission / reception unit A warm water temperature lowering instruction signal is transmitted by radio waves from 2f.

  The heat source control unit 1d that has received the set temperature lowering instruction signal by the heat source side wireless transmission / reception unit 1e lowers the output of the heating element 1a and lowers the hot water temperature.

  Next, when the room temperature in the room A falls below a predetermined temperature, the heat radiation control unit 2e detects the room temperature drop by the heat sensitive body 2a and increases the output of the fan 2c, or increases the flow rate of hot water by the valve 2d. In addition, a warm water temperature rise instruction signal is transmitted by radio waves from the heat-radiating-side wireless transmission / reception unit 2f.

  The heat source control unit 1d that has received the warm water temperature increase instruction signal by the heat source side wireless transmission / reception unit 1e increases the output of the heating element 1a to increase the warm water temperature. The room temperature of room A is controlled in such a repetition.

  The room temperature of the room B can be controlled in parallel by the room B radiator 3 using the same control method.

  In the present embodiment, only the two rooms A and B are heated, but the number of radiators may be increased as long as the output of the heating element 1a and the capacity of the pump 1c are allowed.

  In the hot water heating system described above, as a prevention of freezing in winter, when the heat source control unit 1d detects an extreme decrease in the hot water temperature when no operation instruction signal is received from any radiator, the pump 1c is driven to generate heat depending on the case. The body 1a is driven, and a valve opening instruction signal is output by radio waves from the heat source side wireless transmission / reception unit 1e and received by each heat radiation side wireless transmission / reception unit (for example, 2f). 2d) is opened.

  Thus, in a hot water heating system that transmits and receives signals such as start, stop and temperature change requests from the radiator to the hot water heat source machine, valve opening instructions from the hot water heat source machine to the radiator and operation monitor signals, etc. by radio waves If there is a similar system in the neighboring house, for example, the following is a solution to the concern that the neighboring house's hot water heat source unit may be operated by the operation instruction signal transmitted from the heat radiation side wireless transceiver 2f. To do.

  When the contractor gives a trial operation instruction to the heat source control unit 1d during the construction trial operation of the hot water heating system, the heat source control unit 1d outputs a trial operation instruction signal together with a hot water heat source unit registration number registered in advance at the time of shipment from the factory. It transmits by radio waves from the heat source side wireless transceiver 1e.

  Then, all the radiators within the reach of the radio wave are received from the radiation side radio transceiver unit (for example, 2f), and the radiation control unit (for example, 2e) stores the hot water heat source unit registration number and drives the fan (for example, 2c). And opens a valve (for example, 2d) to enter a test run state.

  If it is a signal from a hot water heat source machine in a neighboring house to which no hot water pipe is connected, the hot water will not reach indefinitely. If it is a signal from the hot water heat source device to which the hot water pipe is connected, the hot water will eventually reach the air heat exchanger (for example, 2b), and the temperature rise can be detected from the heat sensitive body (for example, 2a).

  The heat dissipation control unit (for example, 2e) permanently stores the registration number of the hot water heat source unit that has detected the temperature rise, and at the same time when the operation instruction signal is transmitted from the heat dissipation side wireless transmission / reception unit (for example, 2f) in the normal operation after the trial operation is completed. Also send the registration number of the hot water heat source machine.

  The heat source control unit 1d determines whether or not to perform the heating operation based on whether or not the signal received from the heat source side wireless transmission / reception unit 1e matches the registration number of its own hot water heat source unit.

  If it does in this way, the hot water heat source machine of a neighbor will not operate.
