Variants of safety devices relate to water heaters in circulation heating systems, in particular of operating on solid fuel. Temperature regulation element (3) of the devices is placed in contour of hot water. Telescopic rod (4) is tightly pressed to slide valve (2). Body of distributor (1) is connected to output hot water tube in such way that the rod (4) of temperature regulation element (3) is in contact with hot water. Body of slide valve (2) is connected to tube for hot water takeoff and to source of cold water inflow to heater. At exceeding given temperature of water valve (2) is switched with temperature regulation element (3) and connects the circuit of hot water with respective discharge pipe, and source of cold water – to the system. According to the second variant cold water is under pressure directed to exchanger through which hot water from heating system goes and cools it. The invention prevents for water temperature in heater exceeding emergency one even after de-energization. |
