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.

The service was great this year which improved comparing with last year. The engineer text saying that was arriving in 30 minute which was assuring that will be coming. Last year I was waiting from 2 to 6 pm and noone came. When I called I have been told that the engeneer came but none was at home which was not true as I was inside the house the whole time. So I had to pay extra £50. But this year the service was improved so 5 stars well deserved.

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.

PAT Test. I asked them to give me 30 mins notice so I could get to the rental property which they kindly did. They were quick and efficient, and emailed me the PAT certificate the next day.

Elle and the team at Efficient Home Energy were great. Prices were brilliant, next day service and great communication. Certificates were issued day after inspection and works were completed. Couldn't ask for more. Great company and will be my first port of call going forwards. Highly recommended.
