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.
THERMOSTATIC RADIATOR VALVES
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.
