Problem Solving: Central Heating

From time to time, you will encounter some issues with your central heating that can be quite a nuisance, particularly in the colder months of the year. Being able to spot a problem early can save you a lot of time, money and hassle by rectifying the issue before it causes too much damage to your home or building.

Faulty Radiators

Checking your radiator can be a very effective way to determine the nature of a fault in your home. A common problem is air pockets forming in the top of your radiator, which stops hot water from reaching that section. This issue can be identified by feeling the top of the radiator while the heating is on; if it’s cold, there is an air pocket.

This can be solved with the method that is known as ‘bleeding’ the radiator. Simply turn off the heating, use the radiator key to loosen the air bleed valve and release the air (you will hear a hissing sound as the air escapes). Once that’s done, simply mop up any water and tighten the valve again.

Similarly, if the bottom of your radiator is cold, it is a sign that there is a rust and sludge build-up in the system. This can be removed by using a sludge-remover product, and this same product can also help the efficiency of your system.

Knocks and Creaks

If you can hear knocks and creaks in your pipes, the reason for this is often that the area they pass through is not wide enough to accommodate for the expansion that occurs when water flows through the pipes. If the area is too narrow, the pipes will rub against the joists and create that knocking noise. To solve this issue, you may need to make some alterations to the joists where the rubbing is occurring, cutting a bit away to make it wider.

Noisy Boiler

While a boiler usually heats your home with minimal noise or fuss, a common fault that can occur is the onset of noises and banging from the system. This can be caused by a number of issues, from a build-up of sludge and scale which causes some areas to heat up more than others, to excess air in the boiler. If there is sludge and scale in your system, pockets of steam are created which are the reason for the banging sounds, along with noises resulting from the restriction of water flow. To remedy this issue, it is important that you seek the assistance of a registered, licensed professional.
