What are solar filling & testing equipment kits 

Solar thermal filling and testing kits are designed to be used during the installation or testing process of a solar thermal heating system.  

When installing a solar thermal system, the testing kit indicates to the installer the best orientation for the solar panels to ensure maximum solar energy collection and checks that the right antifreeze level is present in the thermal fluid.  

During maintenance checks of the solar thermal heating system, the solar testing kit can be used to check on the performance of the system and on the condition of the thermal fluid as, in time, degradation occurs and it will need replacing. If your solar thermal system requires a change of thermal fluid, we recommend having a look at our range of thermal fluids here. 

Helping you find the filling & testing equipment for solar thermal heating systems you need 

Solar thermal testing kits are a must for anyone installing a solar thermal system or carrying out maintenance work on one. Most solar thermal testing kits include a compass, a radiator key, pH papers, an infrared thermometer, a refractometer, a dropper and a sample bottle.  

Our most popular solar testing equipment is the Sentinel SolarCheck Testing Kit, perfect for installation validation checks and ongoing monitoring.
