Why your home radiator is too hot

Radiators usually keep rooms at your desired temperature, but occasionally they pump out too much heat or they’re too hot to touch.

Three reasons:

• The thermostat may not realize the temperature is too high. Then it will fail to send a message to the system to reduce the heat.

• The thermostatic valve can be stuck in a position where it fails to detect the extra heat. Unless it is stuck, the thermostatic valve will regulate the amount of hot water flowing to the radiator.

• I f you have a combi boiler the diverter valve may have accumulated enough debris that it no longer functions properly.
