How to maintain power with a powerflush

Powerflushing your boiler is one of those things you only hear about when you come to get your boiler serviced. And with a flush only needed once every 5 years, it’s easy to underestimate its importance. According to plumbing company, PTS’ John Byrne, “a recent survey of more than 1,600 installers by ADEY Professional Heating Solutions revealed that only 46% favoured either a traditional powerflush or a system flush to cleanse a central heating system”.

A powerflush is often the best solution for a water circulation problem and it’s a lot like owning a car. You need to keep it well oiled and fire it up every now and then to keep it running smoothly! Regular maintenance will give you the best results and help stop a problem from building. So, it’s something that we should all keep in mind.

Why powerflush?

Over time, sludge can build up in your radiators and reduce their heat output by as much as 15%. Because the heating system has to work harder, you’ll see an increase in your heating bills too. If you opt for the flushing treatment, the temperature will even out throughout the radiators and you won’t have any cold spots to deal with.

For an extra boost, it’s recommend to invest in a powerflushing pump to encourage future debris to move through the system. The water is pushed around much faster than with a standard system circulator and this discourages the waste from settling – warding off repeated visits from a heating engineer!

What exactly is it?

Well, without going into too much detail, the flush involves a pump and flow reverser device being connected into your heating system. Water and a sludge crust breaker work their way through the system to loosen any built up rust and sludge. A descaler breaks down limescale and the dirty water is washed out with a clean flow. To finish up, a corrosion inhibitor is pushed through the pump to prevent any future rust and sludge from sticking to your internal pipes.

How much will it cost?

Cost shouldn’t be a barrier when you remember that this is a once every 5 years job. But the cost of the treatment depends on the size of your home, how many radiators you have and the average gas engineer cost in your area. To give you an idea, you can expect to pay between £275 and £650 for the typical 3-bed home with 8-12 radiators.

As this works out at an average of £55-£130 a year, it’s really worth it, as an inefficient system will cost you at least that on top of your heating bill the next time around…
