People are often surprised that a large number of boiler breakdown call outs are due to dirty water and sludge within the boiler system. If dirt and sludge have built up within your central heating system it can have a huge effect on how well your boiler runs and how efficient it is.
A central heating power flush is a great way to clean out your system and make sure it is working at its best.
We use the term power flush to describe a chemical solution that cleanses your central heating system and removes anything inside of pipes, such as rust or debris that may be causing it not to work as well.
If such debris is left inside of your system, it can cause serious problems to your home heating. You will find that over time the water in your pipes, boiler and radiators as they produce unwanted dirt can cause your radiators to not give out as much heat or indeed cause your boiler to break down completely.
A power flush removes the sludge in your system, preventing blockages and central heating inefficiency. This means that your radiators and your boiler can work better to heat your home, and thus prolonging the life of your heating system.
Our engineers at Coleraine Plumbers are well placed to advise you on whether this is something that will benefit your system. We’ll arrange for an engineer to check your heating system is suitable for a Powerflush. The following systems can't be Powerflushed:
Electrical heating systems
Twin-entry radiator valves
Pipes of less than 15mm in diameter
You may already be experiencing things within your home that are already giving indications that a power flush will be helpful.
The most common signs that your central heating system may need a power flush are listed below:
Leaks coming from your radiators or your radiators and boiler are noisy
Some radiators struggle to heat up as well as others
The radiators have cold patches, especially at the bottom
The radiators are not getting warm, even when the boiler is turned on
No water escapes when you bleed a radiator
If when you bleed a radiator, the water is discoloured.
The central heating takes longer than expected to warm up
There is excessive noise from the boiler or the heating system pump
The boiler keeps breaking down and needs to be restarted
The tap water is cloudy
If you have a new boiler, it is important that all sludge is removed from the system, or this could clog up your new boiler, making it less efficient and leading to future breakdowns.
Many times a Powerflush helps deal with heating problems that you can't always see. It helps prolong the life of your system, lower your bills and reduce the risk of breakdowns.
A common question people ask is how long does a power flush take? This will vary according to your house size and heating system. A power flush will take less time to perform if you have a combination boiler or sealed system because there isn’t a need to cap off the cold feed and expansion piping.
Usually it takes around half a day to power flush a system thoroughly. You can typically expect a power flush in a three bedroom house with a vented system to take around 5 hours to perform.
It is always advised to have a power flush performed by a qualified professional. Our reputable engineers are trained to handle the specialist chemicals and equipment that a power flush requires.
What happens is that we use a machine and three-step chemical process to thoroughly clean out your boiler, pipes and radiators, and replace dirty sludge with clean water using a cleansing agent. We'll need to drain the heating system down and flush every radiator individually. We can then get rid of the waste down a suitable outside drain.. After the Powerflush has removed sludge from your pipes, radiators and boiler, your system should work much better.
It will improve the circulation of water within your system and makes it more efficient. Your radiators will heat more quickly. It'll reduce the risk of breakdowns, cold radiators and noisy boilers. Reduces system wear and tear and helps to protect your boiler
It is also a good idea to think about having a power flush on your whole central heating system when you have a new boiler installed. A power flush to your central heating system is recommended every 5-6 years to keep your boiler in tip top condition and working as you’d expect.
