It's the reason some radiators are cold at the bottom while warm at the top, why heating up takes longer than it used to, or why you're hearing banging or gurgling from the pipes. A power flush is the fix: a deep clean of the whole system using a specialist pump and cleaning chemicals, done properly rather than as a quick top-up. We connect a power flushing unit to your system, circulate the cleaning solution, and work through each radiator until the water runs clear. It's not a quick job, usually five to eight hours depending on the size and condition of your system, and your heating and hot water will be off while we work. Once everything's flushed through, we add a corrosion inhibitor to help protect the system going forward. > A clean system heats faster, runs quieter and puts less strain on your boiler. It's worth being upfront that a power flush isn't a magic fix for everything. If there's a mechanical fault, a leak, or a failing part somewhere in the system, that needs sorting separately, and we'll always tell you honestly if that's what we're seeing rather than just flushing and hoping. More information ### Who tends to need one Most people come to us because a radiator's been cold at the bottom for months, or their boiler's started making noises it never used to. Others are having a power flush done as part of a wider job, for instance before we fit a new boiler, since installing a new one onto a sludgy old system just shortens its life. As an accredited Vaillant installer, we know how important a clean system is to keeping a new boiler running well and its warranty intact. We are based in Woodingdean and cover Brighton, Hove, Worthing, Lewes, Shoreham-by-Sea, Haywards Heath, Seaford, Burgess Hill and surrounding Sussex towns. Whatever the age or type of your system, we'll take a proper look before we start, explain what we find, and only recommend a flush if it's actually going to help. > We'd rather tell you a flush won't fix it than take your money and hope for the best. If you're dealing with cold radiators, a noisy heating system, or you're planning a new boiler installation, get in touch and we can talk through whether a power flush is the right next step. ### Ready to talk?

[Underfloor Heating Repair→](/services/underfloor-heating-repair) ## Before you book Here's what people usually want to know before booking a power flush. How do I know if I need a power flush? Common signs include radiators that are cold at the bottom, radiators that take a long time to heat up, or a boiler that's noisier than usual. We'll check your system first to confirm a flush is actually the right fix. How long does a power flush take? Typically five to eight hours, depending on the size of your heating system and how much sludge has built up. Your heating and hot water will be off while we carry out the work. Will a power flush fix my heating problems completely? It clears sludge, rust and debris from the system, which solves most circulation and cold radiator issues, but it won't fix a mechanical fault, leak or failing part. If we spot something like that, we'll flag it separately. Do I need a power flush before a new boiler is fitted? It's often recommended, since fitting a new boiler onto a sludgy old system can shorten its life and affect warranty conditions. As an accredited Vaillant installer, we'll advise honestly on whether your system needs one first. Is R.K Plumbing & Heating qualified to do this work? Yes.
