The boiler is for heating and supplying a heat medium such as water to a constant temperature by any heat source,

Oil boilers or gas boilers are commonly used as boilers, and boilers using such oils or gases generate sparks by oil or gas and heat water heaters such as copper tubes by the sparks and the heaters. The heating medium (water) filled in the inside and the heated heating medium is to be supplied with heating and hot water.

On the other hand, due to the continuous rise in oil and gas prices, the use of oil and gas boilers is gradually decreasing, and in order to replace them, the use of electric boilers that are more durable and safer than the use of oil or gas is extremely high. It is the situation.

Therefore, in general, a conventional electric boiler system for heating a heat medium such as water or oil is composed of a heater having an inlet and an outlet formed therein and having a hollow portion for accommodating a heat medium therein. A plurality of rod-type electric heaters are incorporated therein, and the heat medium filled in the hollow portion is heated to a predetermined temperature by the operation of the heater to circulate the heated heat medium to the hot water and the heating water pipe by the circulation pump.
