Most of the time, our central heating systems work quietly in the background, providing us with heat and hot water exactly when we need it. With the weather turning colder, many of us are starting to turn our heating back on, to keep our homes cosy and warm throughout the winter.
This winter, if you find your central heating isn’t working as it should, read our guide to the top 5 reasons why this might be.
1. There is trapped air in the radiator system
Usually the radiators in our homes heat up quickly and provide enough heat to keep the entire space warm. If you have hot water, but no heating, it is likely that there is air trapped in your radiator system. This could lead to cold spots in the system leaving some of the radiators totally cold and others only reaching a tepid, lukewarm temperature even with the thermostat turned up high.
To resolve this problem, you can bleed the radiator system to clear trapped air and allow the water to flow freely once again. This is a very common problem with a comparatively easy fix, that will see your radiators heating up to their desired temperature.
2. There is a build up of sediment in your heating system
If bleeding the radiators didn’t fix the problem, then it is possible that there is a build up of sediment in your system that is preventing the flow of hot water. Over time, sediment and limescale can settle along the bottom of the water pipes, causing a blockage and preventing the heating system from working.
Ideally, you will want to avoid having to replace heavily scaled pipes as this can be time consuming and costly. In the first instance, a heating engineer will powerflush the central heating system, to try and clear any build up, allowing the water to run freely through the system.
3. Your pipes could be leaking
Pipework can deteriorate over time, leading to split hoses and loose joints. If your heating system is very noisy, it is possible that the pipes are coming away from their fittings, causing them to knock together and eventually leak. Your heating engineer will be able to visually examine the pipework and replace any old pipes that are corroded or broken. Larger leaks may require an extensive amount of replumbing that should only be handled by an experienced central heating firm.
4. Electrical faults in the control panel
Modern day boilers are controlled using electrical panels that start and stop the system as and when necessary. Electrical components can easily fail as they age, which can prevent the heating system from firing up when called upon to do so by the thermostat. An experienced central heating engineer will be able to fix the problem by resetting the system or replacing electrical components that are no longer operational.
5. Your central heating system is very old
Boiler, radiators and pipe work can remain operational for many years. Most though, will start to fail at some point during their lifetime. Older boilers often do not have the capacity to efficiently heat houses that have been extended or refurbished, they are also not as energy efficient as more modern condensing boilers. Before you decide your boiler needs replacing, speak to a heating engineer who can help you determine if its time to upgrade your boiler to a more energy efficient one.
