Looking for a Central Heating Powerflush Company In London?

Maintaining your heating system is essential to keep it running at maximum efficiency throughout the winter months. Over time, sludge buildup can occur in your radiators and pipes, which can cause poor circulation and lead to breakdowns. That’s why we offer a ‘deep clean’ service that removes sludge and debris from the central heating system.

At our heating system cleaning service, we understand the importance of efficient heat distribution in your home, especially during cold days. If there are visible cold spots on your radiators, it could be a sign of buildup inside your system. This buildup can lead to reduced heat output and higher energy bills. That’s why we use the latest flushing technology to clean your heating system thoroughly. Remember, a radiator should radiate heat uniformly throughout, not just at the bottom. Our professional boiler engineers can assess your system and offer a power flush to remove any buildup and get your heating system back to peak performance, just like a new system.

Contact our helpdesk today or ask for a quote online and ensure the proper flow of new pipes.

Maintaining a clean heating system ensures maximum efficiency and reduced energy bills. The process involves water flushing out the central heating system using powerful chemicals and a specialised machine that removes debris and sludge from the system. Any obstinate blockages are removed under force (1 – 2 bar) to ensure the circulating water reaches every part of the central heating system and gives heat and hot water, when needed, throughout the property.

If you’re experiencing cold spots or lower than usual heat output, it may be time for a powerflush to improve the system’s performance.

Radiator cold spots, the boiler runs almost continuously without the radiators reaching the pre-set TRV temperature or pre-set room temperature. Usually, it’s down to sludge in the system, which must be removed.

Should you experience any of the aforementioned scenarios, it may be time for a comprehensive system assessment and powerful flush.

If you’re experiencing poor central heating performance, a powerflush may be necessary to get your system back on track. During the powerflush, a boiler engineer will use specialised equipment to flush out any solid particles or contaminants clogging up your pipes and radiators. To begin this process, the engineer will isolate the boiler, shut off the water, and open all the radiator valves, ensuring the diverter valve is also open.

Next, the engineer will use a powerful chemical mix to break up any debris and push it out of the system. Once the flushing process is complete, your central heating will run efficiently again. If you’re considering a powerflush, be sure to have a quote from a professional service provider to understand the costs.

There’s no need to suffer another winter with only partial heating as the solution is right here at serviceteam.

The central heating will be tested and put through its paces, and every radiator will be checked to see if maximum heat output has been restored. Not only will your heating system work more efficiently, but you may also see a reduction in your energy bills.

Timing. There isn’t the best time to complete a powerflush; just get it done as soon as the above signs are evident. However, summertime is usually the best time as engineer availability is plentiful compared to winter.


We recommend having a Magnetic System Filter installed at the same time as the powerflush.

A system filter captures any metallic debris circulating the system, stopping it from reaching the boiler and causing a breakdown!

Frequently Asked Questions

Q: Does a powerflush work?

Yes, it’s a powerful way to drive out any unwanted debris from the boiler/heating system and return it to maximum performance. It also protects against damage and future breakdowns caused by sludge and debris accumulation.

Q: Can a powerflush cause a leak?

Depending on the age of the radiators, the pipework, and the initial installation process, radiators can leak during a powerflush when under pressure if they are old and show signs of rusting. If they are, then consider replacing them. Our engineer will check all visible pipework and ensure the system holds pressure before leaving the property.

Q: Do I need a PowerFlush?

It depends on the age and the symptoms you are experiencing. If you have never had a system powerflush before, then your boiler system probably needs one. The best way is for a heating engineer to carry out a few tests to understand if one is needed.

Q: How long it takes for a powerflush?

It depends on how much sludge is in your boiler system and the system design. Usually, a powerflush can take half to three-quarters of a day, depending on the system size.
