Are your radiators cold at the bottom, do you have fluctuating water temperature, a noisy boiler or even a cold house due to blocked pipes?
If so, then a power flush could be the answer to your problems. A power flush and high pressure jetting is a cleansing process which aims to remove deposits of sludge, rust and any other debris from your central heating system. These contaminants, if left, can seriously affect the efficiency of a heating system and in severe cases a power flush is the only option available.
Over a period, the central heating system may start to show signs of inefficiency due to various reasons. A noisy boiler or fluctuation in water temperature could mean that your heating system needs power flushing.
