A problem with the underfloor heating is one of the commercial landlord's worst nightmares.
Tom, of Power Flush UK, came out yesterday to power flush our heating system. Prior to his visit we had several radiators which were not heating up and others which only got lukewarm. He did a first class job. The house is now much warmer and the 3 radiators which were the biggest problem are now red hot. He also gave me some excellent advise on how to best operate my system. Tom arrived precisely on time despite travelling nearly 2 hours to get here. There was no mess. I highly recommend them to anyone thinking they need a power flush.

I'm really pleased that Tom managed to get my central heating working again by flushing out the radiators and pipes. He did a very thorough, expert job and didn't leave until the heating was working correctly. This firm was recommended by a trustworthy plumber and they did not disappoint! I would recommend them to anyone as they sorted my problem out (radiators not heating up) in one day. All toasty for the winter now! Ben was an excellent communicator and I'm a happy customer.

Big shout out to Tom and Ben of power flush UK. Our system had cold spots all over it no matter how it was rebalanced but was roasting hot all over by time Tom had given it a good flush out. Everything was explained thoroughly so not only was I left with a working system, I gained a lot of knowledge for future maintenance. They even brought a separate pair of indoor shoes to limit any mess! Friendly and professional service all round. Jolly good show boys!

If your central heating isn’t working properly, these are the guys to call. I have a micro-bore system which had completely given up the ghost, with almost no heat output. Ben arranged a rapid appointment, juggling around his diary to suit my needs. Tom arrived as promised and was fantastic. He explained clearly what he was doing at each stage, and why. After flushing the system both ways, he then flushed out each radiator one by one until the water ran clear. I was amazed at the amount of gunk that was pulled out - literally the water was black. Once he was done the system I thought might never work properly again was perfect. Instant heat to all the rads and cylinder. Boiler runs smoothly now without cutting in and out. Tom cleared up what little mess there was, replaced two valves in the airing cupboard that were faulty, and added a new valve to isolate the header tank all free of charge. I couldn’t be happier. I thoroughly recommend this company and will definitely use them again in 5 years time to keep everything running efficiently.

Great job done by Tom. System clearly needed a flush out with all the grime and build up over the years. Tom arrived promptly as agreed and went through the job step by step showing what had been done. He also provided additional info on getting the best out of the heating system and was very tidy during his time here Would have no hesitation in recommending.

If your radiators are cold at the bottom while warm at the top, this can be an indication of rust or sludge build-up at the bottom, preventing the full circulation of hot water.
Strange noises, such as banging or kettling, coming from your boiler can be a result of build-up causing uneven water distribution.
When bleeding your radiators, if the water is discoloured or murky, this suggests there might be rust or sludge present in the system.
If you find yourself needing to frequently bleed your radiators to release excess air, this could indicate a circulation problem.
If your boiler frequently shuts off or needs to be restarted, there might be circulation problems due to blockages.
Check external pipework and radiator surfaces for signs of corrosion, which can indicate internal issues.
If your heating system is old and has never been power flushed, it might benefit from the procedure, even if there aren’t immediate signs of issues.
A noticeable increase in energy bills without a significant change in heating usage can point to an inefficient heating system, possibly due to sediment build-up.
Powerflushing is purely and simply a way of removing the rust that slowly builds up in your heating system and boiler over time. Water, chemicals, powerflush equipment and an experienced plumber are used to remove the rust and sludge from your central heating. The flow of the machine is reversed from time to time using special three-way valves attached to the flushing pump. This is an extra step to help clean the pipes and radiators.
Yes, at the end of each job we will give or post a certificate to you.
The reason that happens is generally one of two things:
1. Your pump has failed or is stuck. The water can’t circulate and therefore the water that is in the heat exchanger will boil very quickly. In some older boilers in particular it takes a while for the thermostat in the boiler to turn the gas off. In modern condensing boilers the thermostats are more sensitive and will extinguish the boiler flame quickly.
2. There is a blockage in the main flow or return pipework, or with the water ways in the boiler heat exchanger which is either completely or partially blocking the flow of water through the boiler – so the water in the boiler starts to boil and make steam again. Hence the popping, hisses and bangs.
If you have seen someone else’s system power flushed you will know what an amazing amount of rust and radiator sludge can come out, in all shapes and sizes. But, contrary to popular belief the vast majority of the sludge that you see does not come from your boiler. Most non-condensing boilers (those installed before 2006) have cast-iron heat exchangers and they, by and large, do not rust. The vast majority or rust and/or sludge in your heating comes from the radiators themselves as they are made from mild-steel.
Yes, there are other ways of cleaning your central heating system, but they are nowhere near as effective as using a the right machine when it is used by a competent and experienced heating engineer. You can add any chemical cleaner in to the system, leave for up to four weeks (Warning:careful here if you have micro-bore pipework) and then open up the system drain-cocks and let the water run out.
When you do that the only force moving the water out of the system is gravity and that will not pick up any larger bits of rust. Those will be left in nooks and crannies.
