Power Flush
A professional powerflush is one of the most effective ways to improve the performance of your central heating system. Using specialist equipment and cleaning solutions, we remove built-up sludge, rust, and debris that restrict water flow and cause radiators to heat unevenly.

It is also strongly recommended before or alongside a new boiler installation, helping protect your investment from contamination already present in your pipework and radiators.
