Each month there are thousands of internet searches for ‘how to fix central heating’ ‘how to fix my boiler’. This is no doubt done in a rush as you wake up to a chilly home or are welcomed with a cold shower. However it is important to understand that ONLY a qualified Gas Safe engineer should EVER diagnose a fault(s) with your heating system and / or boiler. If you have an oil boiler then this should be done by an OFTEC technician.
Whilst it may not always be necessary to call out an engineer, you should NEVER remove your boiler’s exterior case to attempt to fix a fault as this can be very dangerous.
The first port of call is too attempt to ‘reset’ your boiler. Use your boiler manual to locate the reset button then hold this down for up to 20 seconds. After a short wait your boiler should start working again. If this fails to work you can try for a second time.
To check your boilers pressure, first ensure your boiler is cold. The pressure should be between 1 and 1.5 bar on the pressure gauge.
When the pressure is too high on your boiler then it is likely there is too much water in your heating system. If the pressure is too low then the system needs topping up with water to maintain the pressure.
