- a combined heating and hot- water gas boiler heats water circulating through a heat exchanger and circulates the hot water to a heating pipe or to a hot- water heat exchanger.
- the hot water heated by the heat exchanger circulates through a hot-water circulating circuit for hot- water supply and heating.
- FIG. 1 illustrates an example of the hot- water circulating circuit of the combined heating and hot- water gas boiler.
- Water is supplied to a heating pipe 4 of the gas boiler, and air in the heating pipe is discharged to a water tank 3 through a hot- water restoration pipe 1.
- the water in the heating pipe 4 is restored by the driving force of a circulation pump P and heat-changed when passing through a heat exchanger 6 heated by a burner 6.
- the hot water circulates into the heating pipe 4 through a hot- water supply pipe 7 by guidance of a direction-switching valve 2 in which a hot- water heat exchanger 8 is branched off.
- the typical gas boiler having the above-mentioned pipe arrangement is controlled by a controller incorporated in a control box.

- the hot- water restoration temperature gradually increases.
- the controller of the thermostat 14 controls the flow controllers 18 so that the amount of hot water required to maintain the restoration temperature of 62 0 C can flow through the hot- water restoration pipe 1.
- the amount of hot water should be greater than the minimum amount of restored hot water to prevent the boiler from stopping operating.
- the restoration setup temperature of 62 0 C is maintained by gradually closing the flow control valve 18b while monitoring the restoration temperature of hot water.
- the boiler stops operating.
- the restoration temperature of hot water is maintained within a predetermined range, such that the indoor temperature gradually increases.
