A Water Heater Temperature Controller is a mechanical device that uses a sensing bulb and capillary tube filled with a temperature sensitive fluid. As the water heats up the fluid expands and creates pressure that switches the heating element off when the desired temperature is reached. When the water cools the fluid contracts and switches the heating element back on to maintain the set temperature. Known for its reliability, simplicity and cost effectiveness this controller is used in residential, commercial and industrial water heaters and provides temperature control without electronic components.
Jaye Heater Technology Co., Ltd. is one of the most reliable manufacturers and suppliers of water heater temperature controller in China, also supports custom service. Welcome to wholesale high quality water heater temperature controller at competitive price from our factory.
