Underfloor Heating

Underfloor Heating

Wet systems operated from your existing central heating system and/or electrical underfloor heating can be supplied and installed.



Radiators rust internally producing black iron oxide 'sludge'. This sludge moves around the heating system blocking pipes, valves and boilers (pumps/heat exchangers/diverter valves, etc). Using professional powerflushing machinery we can remove sludge, rust, scale and other debris from heating systems. Water pumped at high velocity combined with chemical agents will clean your heating system, leading to a warmer home, reduced fuel bills and an increase in the lifespan of your boiler.
