Power Flushing


Over long periods of time, central heating systems usually clog up with iron fibres and minerals in the water. Power flushing is a natural process that reduces the flow of water and in turn reduces the heating efficiency throughout your property. By using us and our Kamco flushing machines we can restore your central heating system to the best of its abilty by flushing your complete system.
