Not sure if you need a boiler repair?

Although some issues with boilers are obvious and easy to spot, some can go unnoticed and develop into larger issues. By calling out a heating engineer to repair your boiler at these early stages, you can save money and also save your boiler from further damage. Here are some signs to look out for: 


Boilers tend to have a low frequency operating noise that resembles a humming noise. If you notice a change in your boiler’s usual operating noise, it could be a sign of a loose central heating pump or a loose part.

Low pressure

Naturally, boilers tend to lose pressure over time as they get towards the end of their lifespan. However, any dramatic drops in pressure will require further investigation by a Gas Safe  Registered engineer. An easy way to check for low pressure is to read your boiler’s pressure gauge - usually located on the front of your boiler. A healthy pressure is between 1 and 2 on the dial. 

Not responding well to thermostat settings

Take note if your boiler does not seem to respond to the setting on your thermostat. It could be a sign of a deeper problem developing in your central heating system. Call out a heating engineer as soon as you notice an unresponsive boiler.

Regular servicing can go a long way in preventing your boiler from breaking down or needing repair. At McGrath Heating Services Ltd we offer a comprehensive boiler service in which our engineers revitalise your boiler and spot any issues that may otherwise go unnoticed.
