Power Flushing

Over time, your central heating system can be blocked or suffer from reduced flow caused by a sludge build up.  To keep your central heating system flowing and working efficiently, prevent burst pipes in your home and reduce energy bills, a power flush is the answer to your problems. The main symptoms of sludge and scale are a noisy boiler and cold spots on your radiators from a build-up of this scale.


Hot and Cold Plumbers has a dedicated flushing pump, which uses high volume, velocity and low pressure to clean through your system. Special chemicals are used to loosen then mobilise any scale deposits in your pipes and radiators, effectively removing any stubborn coatings to the inside of your system and then flushing them out. The chemicals used to power flush your system will be chosen to suit its exact requirements.

It will be power flushed methodically and thoroughly, pipe by pipe, radiator by radiator, including the boiler. Once your whole system has been power flushed thoroughly we will refill it with clean water, and a corrosion inhibitor will be added to your central heating system. This will be clearly labelled as containing this chemical substance.

A Power Flush is usually completed within one day, but it does depend on the type of system you have and also the number of radiators. Power Flushing of radiators central heating systems will not damage them. However, it is also important to note that power flushing will not repair any existing internal corrosion, and the removal of deposits may expose small leaks. On rare occasions we do see that a leak may show which had been previously blocked by the deposits. These leaks can be remedied.
