不快感や死水の無駄があった。Conventional configuration and its problems Conventional instantaneous hot water heaters open the faucet and allow low-temperature water to flow for a while because there is water stagnant in the piping connecting the hot water supply part and the faucet (hereinafter referred to as dead water). After flowing out, hot water at a predetermined temperature is supplied. Therefore, the user has to continue running water for a certain period of time after opening the faucet until the hot water flows out. Especially when using a water tap, the water that flows out when the faucet is opened causes discomfort and wastes dead water. there were.

There is a nearby tank, and when the tap is opened, the hot water in the electric water heater 3 flows out. As a result, compared to a hot water system without an electric water heater 3, the discomfort caused by the outflow of dead water in the hot water supply pipe 2 is reduced by 3/3, but on the other hand, the electric water heater must be kept energized at all times. However, the power consumption increases, which is uneconomical.
