We are always keen to ensure our customers can get the most out of their central heating system. One way to help ensure that your system is working efficiently is to have it power flushed, power flushing will clear the “gunk” from your system by using chemicals which can dissolve the iron oxide blocking your system. Our machine uses ultra strong magnets to pull out all of the black sludge out of your system.

Our power flushing services are available across the capital, at highly competitive prices. We provide a service that customers can rely on, and our power flushing service makes sure that your systems performance will be optimal.


What is Power Flushing?

Power flushing is essentially the process of using a machine to push water with cleaning chemicals through a central heating system at high pressure. This should dislodge blockages, clear away sludge, and generally clear your system.

While the chemicals work on the sludge, the dirty water will be purged from the system, and new, clean water will replace it. Once the process has finished, your system should have much better circulation, and be working to maximum efficiency, reducing your bills.

Our service

We use modern high standard equipment to carry out power flushing, with high performance chemicals such as Sentinel X800. This chemical cleans the iron oxide and re opens your pipes. This means that you’ll get a highly effective flushing service, leaving your heating system flowing as it did when new.

We use the latest Norstrom powerflush machine which contains magnetic filters to extract the large particles and prevent them re-entering the system. More details on our machine can be found here: Proflush Professional Magmaster – Proflush

Our friendly team are industry veterans, and will be able to carry out the service quickly and efficiently. We’ll do everything we can to minimise disruption, and get your central heating system back to the way it should be as soon as possible.

FAQs

What problems can bad circulation in my central heating system cause?

Bad circulation in a heating system can cause a few problems, and can cost you in energy bills – especially in winter. Poor circulation can mean that some radiators, or even all of them will take a long time to heat up, pushing your boiler to work hard and your bills to rise.

What are the warning signs?

There are a few signs to look out for that may mean you should consider power flushing. If your radiator water is dirty with small black particles or doesn’t get to the right temperature, you should speak to us about power flushing.

How long does powerflushing take?

The time taken to power flush depends on the amount of radiators you have and how badly they are clogged. up to 6 radiators can take around 2-3 hours and up to 15 radiators can take a whole day. The radiators are flushed individually to make sure they are all clean.

What do i need to prepare before having a power flush carried out?

The area around the radiators needs to be clear to access the pipework. The boiler area will also need to be clear so we can access all pipework associated to the heating system. We use water and dust sheets so your floor wont get messy.

It that time of the year to have a Gas Certificate (GSC) done, so as usual for me, I’ve reached out to Efficient Home Energy to have this done. I’ve booked a bundled GSC + EICR (as I thought that I was also due on the Electrical certificate as well). After proceeding with the booking, I got an email from Elle who informed me that my flat still had a valid EICR for another 2 years. After clarification she also proceeded to the refund (since I didn’t need the EICR). It’s this sort of honesty that makes me appreciate soo much businesses like Efficient Home Energy. The GSC certificate was also processed within 24h. The technician that came to the flat was also super professional and such a pleasant person to talk with. Amazing service! Can’t recommend enough for whoever needs services from Efficient Home Energy. Thank you so much!!

I used Efficient Home Energy to produce an EICR. Some remedial work was required which was done effectively by competent and polite technicians though we did have a payment issue that needed resolving and they were not able to replace the faulty sockets with similar looking parts.
