Central heating is something we take for granted. We just always expect it to and when something goes wrong, we are shocked. Here we look at some of the most common boiler problems:

There is no heat or hot water

This is often caused by a defective component, failure of the valve, the water level too low or a problem with the thermostat. The first place to check is the thermostat and boiler pressure to see if it needs adjusting. If the diaphragm is damaged, these parts will likely need replacing. If you cannot identify a problem or suspect that something needs replacing, call a registered gas engineer.

Odd sound

If you start to hear noises other than the usual sounds of humming from your boiler, air in the system is a common problem. Perhaps the water pressure is too low, or your boiler is kettling. Kettling is a sound like a kettle about to boil and is caused by the buildup of limescale in the heat exchanger.

Pilot light

A pilot light going out can be caused by a breeze or a dirt accumulation on the thermocouple stopping the supply of gas. Check if there is a problem with your gas supply as a whole, but if not, you can try to reignite the pilot light with reference to the manual. If this does not solve the problem, contact an engineer.

Cold radiators

When your radiators don’t feel as hot as they should, this could be an accumulation of debris or air causing an uneven heat distribution of heat. This can normally be alleviated by radiator bleeding which is an easy action.
