Repressurising a heating system

Many boilers will need to have their system pressure topped up with water at some stage. To check if your boiler needs to be topped up, locate the pressure gauge on the front of the system. If the dial is too low and is in the red, then you will need to repressurise it.

If your boiler's pressure is too low, it can prevent the system from heating up efficiently, which could lead to a loss of hot water.

If your boiler's pressure is too high, please complete an appointment form.

Watch the below videos on how to repressurise your boiler.
