Power flushing - why you might want it

Power flushing is a process where a central heating system is cleaned of sludge, rust and dirt by flushing it with water containing cleaning chemicals. A power flush machine and filter is attached to your central heating system. Water is then flushed through which cleans the inside of the pipes and radiators.

How does the dirt get into the system in the first place?

Over time your central heating system accumulates limescale, dirt, corrosion and rusting. It comes from the inside of the radiators, pipes and boiler. A power flush will remove this build up from the system. It can also increase the efficiency of the system (by up to 25%) and reduce your fuel bills. By taking the strain off the pump and heat exchanger, a power flush can prolongthe life of the boiler itself. A power flush can reduce boiler noise and remove 'dead spots' or 'cold spots' in your radiators.

What symptoms will I have that require a power flush?

You may need a power flush if:

  • You have had a new boiler installed (as part of the guarantee)
  • If your hot water system is slow to heat up
  • If your radiators need frequent bleeding
  • If your boiler is excessively nosiy
  • If some radiators are partially or completely cold or blocked

Chemical cleaning your central heating system

If you have an old central heating system, it's not always a good idea to have a power flush. What! you say. Well, pushing high pressure water through it can cause leaks to form at the joints in old pipes. And this can be disastrous if those pipes are under the floorboards. In this situtation, a chemical clean is better option. Chemical detergents are placed into the water and the system itself is used to create enough pressure to push the chemicals through. The entire central heating system is drained. Individual radiators that are still blocked can be removed and cleaned individually.

TestimonialI had [sic] problem with my boiler making a loud 'knocking' noise. I called Multi-trade and they sent a plumber to my house. He said the problem was deposit [sic] in the system and recommended a 'flush'. It took around one day. The plumber was very good and very polite. Afterwards, just as he said, there was no more noise from the boiler. I'm really happy about this. It is a very good plumbing company.

Anka Pilsudski, London

TestimonialI am happy to recommend your company for 'power flushing'. I had a very good job performed by your engineer. I am happy to recommend you to anyone.

Victoria Pemberton, Landlord, London

TestimonialWe had dead spots in all of our radiators. The house is pretty old. As the winter was approaching, I wanted to get this addressed. The Multi-trade engineer recommended inserting chemicals into the system to cleanse it. Whatever he did, it worked pretty well. However, several days later, there were 2 radiators which were still not performing correctly, so I called back. I was very impressed when the engineer returned. He removed the radiators and cleaned them individually in the garden. After that they worked very well. And there was no extra charge, which is as it should be. I would say that Multi-trade are an excellent company and you should call them if you have probelms with your heating.

Elisa Saunders, Landlord, London

TestimonialAgain very good from Multi-Trade. I think that should be the end of it. [Radiator knocking noise]
