The Cotherm TSDH1107 immersion heater thermostat is designed for use with 11-inch immersion heaters, providing accurate temperature regulation and reliable control of hot water cylinder heating systems. Rated at 20A, it ensures safe switching of electrical load while maintaining consistent water temperature performance.
Thermostats are essential components in immersion heating systems, controlling when the element heats and preventing overheating of stored water. The TSDH1107 model is engineered for dependable operation under standard domestic and commercial conditions, helping maintain efficient hot water delivery.
