Straight answers

Power flush, your questions

How do I know my system needs one?
Radiators cold at the bottom, brown bleed water, a noisy boiler and a warm pump are the classic four. Two or more and a flush will make a difference you can feel.
What does a power flush cost?
£480 for up to ten radiators, then per-radiator beyond. Larger or heavily sludged systems are quoted honestly after the first readings.
Is it worth it on an old system?
Mostly yes, but a system with existing pinhole leaks can have them unmasked by cleaning. We check radiator condition first and warn you if yours is the rare case where a flush is the wrong money.
