The water heater 1 of the present invention suggests the use of a gas water heater, not an electric water heater. The reasons are three: firstly, a family generally has 3-4 people, an electric water heater can only supply hot water for 2 continuous people, and the later needs to wait; secondly, the occupied space of the water heater is larger; thirdly, the water outlet temperature is too hot, and the handle is carelessly beaten to the hottest gear at the hot water end, so that the water outlet is extremely easy to scald.
Both of the above solutions do not go to the control panel to press the hot water circulation button and return to the faucet when the user needs hot water.
