Power Flushing
Andover, Marlborough & Hungerford
Expert power flushing to remove sludge, scale, and debris from your central heating system. Restore efficiency, eliminate cold spots, and extend the life of your boiler.
Restore Your Heating System's Efficiency
Power flushing is a deep cleaning process that removes sludge, rust, and limescale from your central heating system. Over time, iron oxide (magnetite) and other debris accumulate in your pipes and radiators, causing cold spots, noisy boilers, and reduced efficiency.
Using a high-powered pump, we flush fresh water and cleaning chemicals through your system at high velocity, dislodging and removing years of accumulated debris. The result is a cleaner, more efficient heating system that heats faster and costs less to run.

Common questions about power flushing services in Andover, Marlborough & Hungerford.
How do I know if my heating system needs power flushing?
Common signs include cold spots on radiators (especially at the bottom), discolored or brown water when bleeding radiators, noisy boiler (kettling sounds), slow heating response, and frequent boiler lockouts. If your system is over 5-10 years old and has never been flushed, it likely has some sludge buildup.
How long does power flushing take?
A typical power flush takes 4-8 hours depending on the size of your system and the level of sludge present. Most homes with 8-10 radiators can be completed in a single day. We'll provide a time estimate after assessing your system.
What's the difference between power flushing and chemical flushing?
Power flushing uses a high-pressure pump to force water and chemicals through your system at high velocity, removing stubborn sludge. Chemical flushing is a gentler process using cleaning agents left to circulate for a period. Power flushing is more effective for heavily contaminated systems, while chemical flushing suits mild buildup.
Will power flushing damage my radiators or boiler?
When performed by a professional, power flushing is safe for your heating system. We use industry-standard equipment and chemicals designed for heating systems. In fact, power flushing can extend the life of your boiler and radiators by removing damaging sludge and improving water quality.
How often should I have my heating system power flushed?
Most heating systems benefit from power flushing every 5-10 years, depending on water quality and system age. Installing a Magna Clean magnetic filter after flushing can extend this interval significantly by continuously removing metallic debris.
