ているので循環水は沸騰することはない。The CPU 90a switches the switch 90b from off to on, that is, the operation of the heating device is only radiant heating (this is referred to as the first operation), and the radiant heating and the heating radiator are used to operate the heating (this is the second operation). Waiting until it is switched to off (referred to as operation), and when it is switched from off to on (S 1 ), the fuel supply amount to the combustor 20 by the electromagnetic pump 60 is changed from the steady supply amount of 16 ml / min. a predetermined amount of feed amount setting unit 90c is set, it is reduced to about 3 ml / min (S 2). Steady-state rotation of the blower 80 is, for example, 2400 rpm, and the rotation for performing proper combustion when the fuel supply amount is 3 ml / min is 700r indicated by the solid line.
If it is pm, the rotation set by the air supply amount setter 90d is, for example, 1500 rpm indicated by a broken line, and at the same time as the decrease in the fuel supply amount, the rotation of the blower 80 is reduced to the set rotation speed to supply the air supply amount. Is reduced (S 3 ). The timer is started by starting the counting with the CPU90a (S 4). In this case, the CPU 90a sets the timed time of the timer to, for example, 20 minutes, and the combustor 20 supplies a small amount of fuel 3 ml / m3 during the timed time.
Combustion is maintained by the minute, and excessive air is supplied during the combustion, so that the temperature of the heat exchanger 30 drops from the overheated state of the first operation. Wait until the time measured by the timer reaches 20 minutes, and when that time is reached (S 5 ), drive the damper motor 50 to close the first damper 51 and open the second damper 52. Combustion gas is made to flow into the heat exchanger 30 (S 6 ). Then the amount of fuel supplied to the combustor 20 by an electromagnetic pump 60 is controlled to a desired set supply quantity (S 7), at the same time by increasing the rotation of the blower 80 set supply quantity to meet the air supply amount to the fuel supply amount Control (S 8 ). Then, the circulation pump 70 is driven to circulate the water in the heat medium distribution pipe 31 (S 9 ). At this time, since the temperature of the heat exchanger 20 has dropped to the normal usable state, the circulating water does not boil.

Is reduced, and since excess air is supplied to the combustor at this time, the temperature of the combustion gas is lowered and the temperature drop of the heat exchanger is promoted. Therefore, the temperature of the heat exchanger is lowered in a relatively short time while maintaining the combustion, and the heat medium can be transferred to normal use without boiling.
