The Tesla TS225 Dual Safety Thermostat (11") is a reliable and high-performance replacement thermostat designed for immersion heaters in domestic hot water cylinders. Combining precise temperature regulation with an integrated overheat safety cut-out, this unit ensures both efficient heating and essential system protection.
This dual-function thermostat controls the operation of the immersion heater by monitoring water temperature and switching the element on and off to maintain the desired setting. In addition, the built-in independent safety thermostat provides an extra layer of protection by cutting power if the water temperature exceeds safe limits, preventing overheating and potential damage.
The 11-inch probe length allows the thermostat to extend deeper into the cylinder, making it ideal for use with longer immersion heaters and larger hot water tanks. This ensures more accurate temperature sensing and improved control over the heating process.
Built for durability and consistent performance, the TS225 is suitable for both replacement and upgrade applications, restoring safe and efficient operation to the hot water system.
