As described above, a container storing a heat storage material is circulated in the cooling water circulation route of an automobile engine or in the hot water supply pipe. Store a part of the heat quantity of the cooling water or the hot water to be supplied, and use this heat quantity in the hot water supply pipe while the cooling water is being cooled by the engine stop or while the hot water is not used. When it is being cooled down, it can be taken out for immediate heating or hot water supply.
If the time until the vehicle is restarted or the hot water valve is opened again is long, the amount of heat stored in the heat storage container is worn due to cooling and immediate heating or immediate In some cases, sufficient results for hot water supply cannot be obtained.

The present invention has been made in order to solve this problem which has occurred in the conventional means, and is a heat storage container connected to the middle of the cooling water circulation path of the automobile engine or the middle of the hot water supply pipe. A new means to ensure that the amount of heat stored in the cabin is retained without being dissipated even after being left for a long time, so that immediate heating in the cabin or immediate hot water supply from the hot water tap can be sufficiently achieved. The purpose is to provide.
