Power Flushing Services, Newbury, Reading and Swindon

Efficiently and effectively clean your central heating system internally by removing limescale and corrosion debris with Power Flushing to improve your radiator performance and heat output. 

Power flushing is not a high pressure operation making it suitable for most domestic wet central heating systems. Carried out with minimal disturbance and disruption to the normal operation of the system, often without disconnecting the boiler or any radiators, 

Power Flushing circulates a cleansing chemical and water mixture under controlled conditions to remove debris from the system. 
Watermarcs Plumbing and Heating provide Power Flushing services throughout Newbury and surrounding areas with a typical cost of £350 for a house with up to 10 radiators, plus £35 per radiator for properties with more than 10 radiators.
