A few seconds after the start of combustion, the electromotive force of the thermoelectric conversion means 11 input from the input terminal 22 rises, and when the safety valve exciting coil 28 reaches the valve opening holding minimum voltage (FIG. 10 Va), the hand is released. At this time, the combustion heating means 9 enters the stable combustion state, but the heat medium transport means 13 is in a state before starting because the electromotive force of the thermoelectric conversion means 11 is small. When the combustion heating proceeds and the electromotive force of the thermoelectric conversion means 11 rises and the electromotive voltage reaches the starting voltage (FIG. 10 Vs) of the heat medium transport means 13, the transport of the heat medium starts.

When the motor 38 starts rotation, the drive magnet 38 directly connected to the rotation shaft rotates, and the rotor 31 in which the magnet portion M is installed rotates synchronously with the drive magnet 38 by a magnet coupling action. As the rotor 31 rotates, the vane 33 moves in and out of the groove 34 to perform a pumping action, and the heated heat medium is pumped to a utilization device such as a radiator.
