PURPOSE:To make it possible to heat warm water without waiting until an engine is warmed up by providing the engine with a heat accumulator mounted on an outboard bound pipe, and with a pump mounted on a return pipe between the engine and a heat exchanger. CONSTITUTION:In case that a cabin is heated with the temperature of a heat accumulator 5 developed, when No.1 and No.2 solenoid valves 8 and 9 are closed, warm water from an auxiliary pump 7 is circulated starting from a bypass pipe 10 to the heat accumulator 5, a heat exchanger 3 and the auxiliary pump 7 in order so that an independent heating circuit is formed, which does not belong to an engine 2. And when a trigger mechanism 13 is concurrently actuated, the substance of the heat accumulator 5 is solidified from a gel condition so as to have it heated. Owing to the heating action, warm water is reheated so as to have it radiated via the heat exchanger 3. In this stage, when air is blown off onto the heat exchanger 3, the cabin is thereby heated. |
