Most people do not know that low pressure in a boiler can have a drastic effect on it's longevity, and many have concerns over whether low boiler pressure is dangerous. A boiler can lose pressure for multiple reasons, it can be due to a leak in the pressure relief valve, an issue in the expansion vessel, air in the system, or a leak in the heating pipework.

How to increase your combi boiler’s pressure
If your boiler pressure needs increasing, we recommend consulting a professional. Our team will be more than happy to help you, taking the following steps to get your boiler back in working order in no time.
1. Identify the filling loop and pressure gauge, the filling loop handles should be at a 90-degree angle.
2. Ensure that you can see the pressure gauge whilst accessing the filling loop.
3. Turn off your boiler.
4. Turn both filling loop handles to match the direction of the pipe until you hear water flowing.
5. Once the correct boiler pressure has been reached (1.5), make sure the handles are fully closed - try not to over-pressurise the boiler, keep your eyes on the gauge at all times.
