We take central heating for granted. We look forward to the heating system turning on. But when it fails, we are left stranded without hot water or a way to stay warm. It is always a problem in the middle of winter! We will look at the most common problems with boilers:

No heat or hot water

A defective component is usually the cause. Other causes include valve failure, low water levels, or thermostat problems. To determine if the boiler pressure and thermostat need to be adjusted, check them first. Most likely, a diaphragm problem or an airlock will need to be dealt with. Call a registered engineer if you are unable to identify the problem or if you suspect something needs replacing.

Odd sounds

Air in the system is a common problem if you hear other sounds than your boiler’s usual humming. Maybe the water pressure in your system is too low or that your boiler is kettling. The buildup of calcium carbonate in the heat exchanger can cause kettling, which sounds like water about to boil. Dirt can accumulate and affect the flow of water, causing it to boil. Strange noises could also be caused by a pump failure.

Drop in the pressure

If your boiler pressure drops too low, it can cause central heating to not work properly. The pressure gauge can give you an idea if something is wrong, especially if the reading is lower than 1. A leak may be the cause of a sudden pressure drop, or you might need to replace the valve. Call an engineer if you have any doubts.

Pilot light

It can be due to a dirty thermocouple or a draught on the pilot. If your gas supply is not the problem, then you can use the manual to reinitiate the pilot light. Contact an engineer if this doesn’t solve the issue.

Radiators with cool spots

It could be that dirt or air has accumulated in your system, causing a distribution of heat that is not even. It is easy to fix this by bleeding your radiators. It may be necessary to balance your radiators if certain ones in your house do not heat up. This is a simple task that involves adjusting each radiator’s valves to ensure it receives enough water.

Thermostat

If your thermostat is not accurate or turns on and off randomly, it may be time to replace it. Check that it’s on and that the settings are correct. Call an engineer if you can’t identify the problem immediately.
