Hints and Tips
Why does my heating stay on when the clock/programmer is off?
This is usually the result of a faulty actuator on a motorised valve.
Why are my radiators cold when my boiler is hot?
This is normally a result of the circulation pump or a motorised valve having failed.

This is usually caused by air being trapped in your radiator. Using a suitable radiator ‘airing key’, you should be able to release the trapped air through the ‘bleed point’ at the top of your radiator.

Your main oil shut off valve can usually be found at the bottom outlet of your fuel tank. The valve will have either a wheel type handle (clockwise to close) or a lever handle (quarter push to close).
