A circulation pump is provided between the return pipe and the discharge distributor, and a heating pipe embedded in the bottom of each heating zone, and an indoor temperature controller for controlling and setting the temperature of each heating zone in which the heating pipe is embedded.

The on-off valve is installed in the tap water distribution device of the heating water. Here, each (gas, oil, electric) boiler is operated according to the setting state of the room temperature controller to provide heating water, and the heating water provided by the boiler is buried as a circulation pump to each heating area through the distribution device of the heating water. After being used for heating and being used for heating, the heating return distribution unit is recovered and circulated back to the (gas, oil, electricity) boiler via the heating return pipe. The circulation of the heating water used for heating is essentially indoors. The circulation pump operates and stops depending on the temperature control and setting of the thermostat and the temperature of the boiler's heating water.

For example, when the heating water temperature and the room temperature are set through the (gas, oil, electric) boiler room temperature controller, the boiler operates the heating water until the heating water temperature reaches the set temperature and heats the heating water. The circulation pump operates to provide each heating. When the heating water temperature of the boiler reaches the same temperature, the boiler is stopped.
