In 1990 Powerflush's founder, Tarquin Purdie, owned a house which had expensive gas bills and cold radiators full of dirty black water. Plumbers explained that sludge causes blockages in pipes, making it harder for heat to circulate to radiators.

The boiler stayed on for long periods, wasting gas, trying to get everything hot, costing much more money than a clean system would and the house still did not get warm. The plumbers, however, were not properly equipped, experienced and more importantly they were not enthusiastic.

Tarquin had 10 years experience of corrosion whilst working as a mechanical engineer for ESSO and Shell. He was soon writing technical guides for Corgi and later Gas Safe showing them the best way to thoroughly clean central heating systems. Nowadays Powerflush Ltd is recommended by Boiler Manufacturers from Ariston to Worcester Bosch, working for home owners across the country.
