HOT WATER BOILER OF HOT WATER MAT TO IMPROVE NATURAL CIRCULATION TYPE WATER FLOW BY PISTON PUMP

摘要

The present invention relates to a hot water boiler of a hot water mat to improve natural circulation type water flow by a piston pump. Therefore, the present invention improves the water flow (improved water circulation rate-improved performance) of a natural circulation type non-powered hot water boiler. According to the present invention, in the natural circulation type non-powered hot water boiler, a piston pump is formed between a water tank and a heater to significantly improve a circulation (supply) rate of water in a circulation hose toward the hot water mat. A piston pump is formed between the water tank and the heater to significantly improve the circulation (supply) rate of the water in the circulation hose toward the hot water mat. A check valve is built inside the water tank to promote one-way flow of the water to facilitate a smooth circulation cycle, while the piston pump is formed so that multiple (two) pumping units can be operated through one drive unit motor, enabling lower manufacturing costs when manufacturing separate heating mats, including singular heating feature. Accordingly, an amount of applied motor can be reduced by 1/2 compared to a conventional impeller circulation pump, so that not only initial manufacturing costs can be reduced, but also an AS cost and maintenance workability such as after exchanging/replacement are greatly improved.;COPYRIGHT KIPO 2019
