Even More Essentials Included

Magnetic Filter

A Magnetic Filter is a filter system which essentially stop your system from building up with Magnetite also known as sludge, increasing energy efficiency and output within the system.


A powerflush is a cleansing process which will clear sludge, rust and any other debris from your central heating system, pipes and radiators. These deposts if left can seriously affect the efficiency of your heating system and can cause cold spots in your radiators, even after bleeding them.

Water Flow

We measure your water flow to determine an accurate boiler size.
