If the tank's water sensor detects that water is full when the tank is full, the user is notified of the end of replenishment by displaying a remote controller and turning off a display lamp or a display LED.

Here, since the user closes the manual valve promptly, the heating water is not replenished more than the full level, so that the outflow of the water from the overflow port at the time of the replenishing water and the thermal expansion of the water of the total heating system are prevented. It is possible to solve the problem that an amount of water flows out of the overflow port.

A third aspect of the present invention has an overflow sensor for detecting that the water in the heating water tank has overflowed. This is a heating water rehydration device having a remote controller having a function of displaying that the user has forgotten to tighten or to perform maintenance of wastewater treatment.

Thus, when the drainage treatment at the end of the overflow uses a container or the like which the user regularly treats,
Before the water overflows from the container and wets the building, causing serious damage to the user, inform the user of the danger of water overflow by using the remote control based on the outflow time of the water at the overflow port and the outflow detection pattern, and take the risk in advance. Can be avoided.

Still further, a fourth aspect of the present invention has a drainage treatment tank having a drainage fullness sensor below the overflow port of the hot water heater, which detects fullness when the water is full. This is a heating water replenishment device having a remote controller having a function of displaying drainage treatment.

As a result, even in the current hot water heater having many additional functions, even if the drainage from these additional functions and the water including the overflow of the heating tank are drained from the overflow port,
When the drainage treatment at the end of the overflow port uses a container that the user regularly processes, by using a wastewater treatment tank that has a drainage full sensor that detects the fullness of the container when this container is full, Before the water overflows and wets the building, causing a great deal of damage to the user, the danger of the overflow can be notified to the user with a remote controller to avoid the danger in advance.
