What Is a Power Flush and How Can It Help My Central Heating?

While many of us invest in looking after our boiler or other heating appliances, our radiators are often neglected; a power flush performed by a professional heating engineer will help to maintain your central heating system and improve its efficiency.

Over time and through use, radiators start to clog up with an unpleasant sludge and fragments of waste which can cause a whole host of problems. A flush will help to clean the system of this debris, allowing clean water to circulate more effectively around your system and giving you the best possible performance from your heating.

How does a power flush work?
During a power flush, your heating engineer will pump a mixture of fresh water and special chemicals through each radiator in turn. As this solution circulates, it removes the build up of sludge that's caused by iron oxide deposits and loosens other damaging and corrosive materials, carrying them back out and leaving your radiator free of obstructions. Radiators do not need to be removed or disconnected from the main system in order to carry out this process; this means minimal disturbance while getting maximum benefits from this service.

How do I know that I need a power flush?
There are several tell-tale signs that power flushing may benefit your central heating - and your pocket! If your system is slow to heat up, if your radiators need to be bled frequently or leak regularly, or if you have cold spots in the middle of them, they are probably a prime candidate for benefiting from power flushing. More serious indicators are lots of unusual noises emanating from your boiler, or if you're heating pump has needed replacing or repairing several times in fairly quick succession.

A power flush is also generally necessary if you're having a new boiler installed; and if you're paying over the odds for your heating bill then you should also look into the possibility of this option. By cleaning your radiators internally, you can improve heat output, prevent further corrosive damage, and help to keep your boiler in tip top condition. If you can improve the performance of your central heating system and save money and further potential problems via a process that only takes a few hours, then it must be worth looking into.

All heating engineers will have their own cost structure for power flushing, and this may be influenced by whereabouts you live. However, expect to pay anything between 瞿30 and 瞿50 per radiator and you should be on the right track. This may seem like a fairly large investment, but if it saves you replacing radiators, damaging your boiler or ultimately having to replace it much more quickly than is necessary, while also saving you money on your monthly gas bills, then it has to be an investment worth making.
