Generally, a heating plate or mat used for a floor or a bed in a home or the like is an electric plate with a built-in heating wire or a hot water mat with a built-in hot water pipe.

Although the electric laminate is thin and has a rapid heating and low cost, it has a built-in heating line inside the laminate, which is a method of heating, and the risk of fire is high due to the characteristics of the product. Especially, when the laminate is folded or used for a long time, There is a fear of fire caused by the electric heating line, and the electromagnetic wave emitted from the electric heating line is harmful to the human body, which is a social problem due to serious side effects.

In order to overcome the problem of the hot-wire type electric plate with the built-in electric heating wire, there has been a hot-water circulating type hot-water mat as a product that has been developed and sold in recent years.

Since there is no electric wire in the mat itself, there is no risk of fire due to electromagnetic wave or short-circuit in the mat. However, since a small boiler for boiling water is separately needed and a hose capable of circulating hot water is installed inside the mat, There is a problem that the burden on the consumer is increased and the burden of the consumer is increasing because of the use of electricity. Technically, there is a problem that the water leaks from the hot water tube and the boiler part, the noise due to the bubble generation occurs in the boiler hot water bottle, and the heating effect is deteriorated due to the water inside the tube when used for a long time.
