The resistance thermostat for the Cotherm solar water heater is an essential accessory for the proper operation of your water heater. Designed to regulate and control the water temperature, it measures the actual temperature and compares it with the one you have set, thus allowing the automatic activation or deactivation of the water heater. The correct operation of the thermostat contributes not only to energy savings but also to the protection of the water heater from damages caused by excessively high temperatures. Continuous temperature monitoring ensures that the water does not reach dangerous pressure levels, providing safety and long-term operation of your device.
