What is Powerflushing?

We carry out central heating powerflushes across Harrow, Stanmore, Watford, St Albans, Hemel Hempstead, Luton, Dunstable, Tring and surrounding areas. If your radiators have cold spots, your system is noisy, or your boiler keeps cutting out, a powerflush removes the sludge and debris causing the problem. We add inhibitor after every flush to protect the system going forward.

Using specialised equipment, we pump a powerful cleaning solution through your entire heating system at high velocity, dislodging and flushing out years of accumulated debris.
