Our range of controls for your solar thermal heating system

Developed specifically for solar thermal applications, our range's solar water heating controls are manufactured from the highest quality materials to cater for extremely high temperatures.

With many of us taking advantage of the renewable heating options available and with the undeniable benefits of opting for solar thermal, we’ve made available a wide range of controls.


Used to detect temperature and irradiation, the most common type of sensor used with solar thermal heating systems is the collector sensor. The most popular sensor in our range is the platinum Solarlogic PT1000 low temperature sensor probe, suitable for use as a storage tank sensor.
