Central heating repair

Need a central heating repair or upgrade?

We cover everything from a new installation, a system upgrade to installing new radiators, replacing radiator valves and carrying out a central heating repair.

Your central heating system is an integral part of your home. We can offer a professional service to install a brand new system from scratch or upgrade part or all of your central heating so you can benefit from a heating system that works perfectly throughout the whole year through all seasons.

So, you’ve decided the time has come to finally replace your old boiler and give a much-needed upgrade to your heating system. The next question is, should I overhaul the whole central heating system and replace my radiators too, while I’m at it?

Think about efficiency

You may think all radiators are born equal, but you’d be wrong. Radiator performance has improved a huge amount in response to quality and performance regulations.

In fact, modern radiators can be up to 50% more efficient than their year 2000 counterparts. This increased efficiency leads to a decrease in energy bills, meaning that your new radiators will eventually pay for themselves.

Modern radiators also channel water more efficiently, with hot water coming into contact with more radiator surface space, whilst using much less water.


Over time the metal pipes and radiators in your heating system can rust, this rust is collected by the water running through your system and returned to the boiler where it can collect. This collection of debris is called ‘sludge’ and it’s a good reason to replace old radiators.

Sludge can build up in old radiators and stop them from heating to full capacity. Powerflushing can sometimes remove sludge build-up but starting from £500 it’s a costly treatment without a guaranteed end result. Sludge formation will begin to build up again after the powerflush as there will still be corrosion occurring in your old radiators.

System filters can be fitted to the return pipes on your boiler, which collects sludge as it passes through using powerful magnets. This can cost anything between £150-£200 for the filter and installation. Many boiler manufacturers offer an additional warranty period if you install their system filter with your new boiler.


Gone are the days of radiators being a purely functional part of the home aesthetic. Modern radiators can be a focal point of a stylish room, with a wider range of styles and sizes than ever before. If you’re updating your boiler then not only can you increase the efficiency with a new radiator but you can also improve your home decor with a designer radiator.


If you are looking to make your system as efficient as possible then you may also want to consider adding thermostatic radiator valves into the mix.
Thermostatic radiator valves have a dial allowing you to control the temperature of each individual radiator in your home. Smart thermostatic radiator valves will monitor your activity in each room and heat them accordingly, you can also programme them from your smartphone.

If you’re thinking about installing new radiators then it would make sense to add thermostatic radiator valves too.


Installing a new, more powerful boiler can lead to leaks in older radiators, due to the pressure increase as water is pumped around the system at a more powerful rate. Leaks can be fixed relatively simply if you have a little DIY knowledge but it can be an unwelcome side-effect of a new boiler if you have older radiators.
Often some of the central heating components are forgotten about and never maintained which can lead to malfunctions or failures, At heathlands our fully trained and experienced heating engineers can investigate and diagnose problems quickly and will advise on the next steps to take.


If you’re thinking about a complete overhaul to your central heating system and wondering whether you need to replace the central heating pipework as well as the boiler and radiators, there are a few factors to consider.

If your boiler is ‘kettling’, also known as ‘dry boiler kettling’, the term for noise created by a boiler not working as it should do, then some further investigation is required. It’s called kettling as it sounds like a kettle boiling, makes sense so far.

So what causes kettling? I’m glad you asked. There are a few issues that can lead to kettling.

A leak in your system, either from the boiler or from your pipework can lead to kettling. Check your system for any noticeable leaks, starting from the boiler and the pipework leading from it. Next, check the pipework around your radiators – a leaking radiator could also lead to your boiler kettling.

If you aren’t able to detect any leaks with a manual search, then it may be time to call in the experts, unless you fancy pulling up some floorboards.
Another common cause of kettling is a build-up of ‘sludge’, as described earlier in this article.

If your boiler is suffering from kettling, then you may want to get your pipework checked out prior to installing a new boiler to make sure it’s not causing any of the issues listed above.

Still unsure about your central heating repair or upgrade?

If you are considering installing a new energy efficient boiler, you won’t maximise savings on your heating bill if it has to pump water through old, inefficient radiators and pipes, so an upgrade might be better than a central heating repair.

Whilst boilers are replaced every 10-15 years on average, radiators often get overlooked as they can’t ‘break down’ as such, but they can underperform. Radiators that haven’t been updated in the last 10-15 years will have a high likelihood of internal corrosion and sludge deposits, hampering efficiency and putting a strain on your heating system.

If you haven’t had a look at new radiators for a while, you’d be surprised how appealing the designs can be and just how many different styles are available. Gone are the days of white block radiators, you can now choose a radiator that will actively complement the style of your room.

Obviously, the cost is a consideration in deciding whether to replace your radiators at the same time as your new boiler; there are other cheaper options you may wish to consider to remedy any issues with the performance your radiators have, before committing to a larger spend.

We would recommend only replacing central heating pipework if it is causing an issue with your boiler, or if any pipes are leaking, as it isn’t worth the disruption and the cost otherwise.

Replacing your radiators when installing a new boiler is recommended if you can afford it, as there are a range of benefits to installing new radiators.

Always ask an expert if you aren’t sure of anything and need some additional advice. Don’t worry, we’re here to help you with your central heating repair or upgrade.
