How to check your central heating water pressure

If your central heating is not working you may want to check and refill your boiler’s water pressure before calling out an engineer. This step-by-step guide will show you how to do this.

A water pressure indicator can be found on the front of most boilers, they are either a dial or a digital display. The indicator should read between one and two bars of atmospheric pressure, if it is below one then your boiler pressure will need refilling. Here are a few simple steps to refill the pressure in your boiler:

1. Locate the cold water feed to your boiler (this is normally a plastic tube located either next to or under your boiler)

2. Find the small tap on your cold water feed and gently turn until your boiler pressure indicator display reads between one and two

3. Once it is between one and two, close the tap

4. Check to see if your boiler is working again

If you are unsure how to identify your cold water feed or any other stages of this process please contact an engineer. If you are a Central Heating Care customer you can call the Customer Services Team on 0845 872 8630, you just need your Central Heating Care account details.
