Power Flushing

Power flushing is the term for cleaning a central heating system of the damaging sludge with the aid of chemicals and a powerful self-contained flushing unit that combines a flow-reversing valve to ensure a high degree of system cleanliness.

This improves performance of the heating system and reduces the energy consumption (i.e. gas). It also prolongs the life of the boiler and the central heating system.

Central Heating Installation

We can offer a full installation service of radiators, boilers and pipework for the central heating system if required. This is not always necessary. We can remove existing boilers and tanks and replace with a modern, condensing energy efficient combination boiler utilising existing radiators and pipework which we will power flush.

We can also add radiators to the existing system for extensions and loft conversions.

We can also replace old fashioned radiator styles with sleek, high efficient stylish radiators.
