How to Tell if There’s a Problem with your Central Heating Boiler

Heating BoilerYour house can be a really miserable and uncomfortable place to be if your central heating boiler isn’t functioning properly. Especially if it’s the first day of October, which the BBC states is the day many homeowners across the UK switch on their radiators for winter.

Boilers can seem mysterious and complicated objects – the kind of appliance most of us are afraid to touch, let alone try to fix.

The most important thing you can do to ensure there’s never a problem with your central heating boiler is get a registered engineer to perform annual maintenance on it. If something does go wrong, there are a few things you can check on your own.

This will help you determine whether everything is hunky-dory, before you call an engineer.

Power supply
In addition to the obvious fuses and circuit breakers, your central heating boiler itself may need electricity – even if it’s gas. If your boiler isn’t working properly, check to see if the appliance needs electricity, and check to see whether anything else electrical isn’t working properly.

Gas supply
First check to make sure that your gas hasn’t been turned off and that the pilot light is on. If the pilot light it out, make sure the boiler’s programmer and thermostat are turned off, and wait several minutes between each attempt to light the pilot. Also ventilate the area if possible.

If neither of those is an issue, push the reset button. Sometimes a safety issue will trip your system and a reset will be required. The reset button can usually be found on the front of your central heating boiler, but it may be a dial that needs to be set to zero and then turned back on.

Finding yourself scratching your head as you try to locate it? Check your owner’s manual.

Heating controls
Your central heating boiler’s programmer and selector controls should be in the on position and the thermostat turned up. Details of these controls are available in your owner’s manual, which you should always keep safe.

Sometimes the controls will “lock” – if this happens, you’ll see a flashing light or a failure code. A simple push of the reset button should fix this problem as well. If the heating controls or thermostat requires batteries, check that those already installed are functioning. If they aren’t, just replace them for a new set.

System Pressure
Pressure is a big issue and a source of many problems, especially for combi boilers. Combi boilers require a minimal level of water pressure, so confirm that the pressure gauge reads between 1 and 1.15 bars. If it’s low, the built-in safety features will likely prevent the boiler from functioning properly. Directions for fixing pressure problems should be available in your owner’s manual.

Boiler Components
Your boiler may have faulty components. Although it’s often difficult to determine whether a part is faulty, especially in condensing boilers on which all parts are pretty integral to the system, there are a few things you can check. The easiest to check is the circulating pump. The pump should be warm to the touch. If it’s either cool or very, very hot, the odds are it’s broken. If it’s cool, check the power issues listed above. But if it’s hot, it can be dangerous, so cut the power supply to the central heating boiler, and get in touch with a repair engineer as soon as possible.

If you carry out all of these checks and still find yourself at a loss as to what’s wrong with your boiler, it may be a case of having to purchase a new one. If you end up in this situation, find out more about the Plumb Center central heating boilers range.
