PURPOSE: A hot water boiler for mats is provided to increase the life time of a pump by preventing overload on the pump through regularly filtering foreign materials. CONSTITUTION: A hot water boiler for mats comprises a hot water mat, a water supply unit, and a connecting hose. The hot water mat comprises a cushion bed. The water supply unit comprises a water pail housing(210), a pump(220), a heater(230), a water level display unit(240), and an outer case. The water pail housing comprises an upper structure(210a), and a lower structure(210b). The pump pumps up the water passing through the water pail housing. The heater circulates water to the hot water tube of the hot water mat by supplying heat to the water passing through the pump. The water level display unit is formed in an outer side of the lower structure. The outer case cages the water pail housing, the pump, the heater, and the water level display unit. The connecting hose comprises a water output line, and a water input line. The water output line delivers water outputted from the water supply unit. The water input line delivers the water to the water supply unit again after circulating the water to the hot water mat. |
