At TOTAL Plumbing & Heating we provide power flushing 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 corrosive inhibitor will be added to your central heating system. This will be clearly labelled as containing this chemical substance. Power flushing usually takes from 4 hours to a day to complete. This all depends on the size, number of radiators and the type of system you have. By removing dirt and blockages in the pipework, you’ll extend the life of your central heating system and make sure it works more efficiently as it heats your home.
