System Cleansing & Power Flushing

If your radiators are cold at the bottom, slow to heat up, or your boiler seems to be working harder than it should, the cause is usually sludge and debris building up inside your central heating system. Buxton Heating provides professional radiator and central heating system cleansing and power flushing services across Surrey, Hampshire and West Sussex – clearing blockages and protecting your system from long-term damage.

Left untreated, the water inside your radiators (the primary water) will rust and corrode your system from the inside out. This creates sludge and debris that reduces or blocks heat circulation, making your heating less efficient and putting extra strain on your boiler. We offer three ways to resolve this, depending on how serious the build-up is.

Chemical Flush
For less severe build-up, we introduce a specialist chemical into your system and leave it to work for several days. We then drain the system down, refill it, and add a suitable inhibitor to protect against further corrosion.

PowerFlush
For more serious blockages, we connect a powerflushing machine to your system alongside a chemical treatment. This pumps high-pressure water through your pipework and radiators to break down and clear stubborn debris that a chemical flush alone can’t shift.

MagnaClean Filter
We fit a magnetic filter to your system that continuously captures iron oxide particles as they circulate. This extends the life of your heating system and protects your boiler’s efficiency long after the initial flush – an easy way to stop the problem coming back.

Do You Need a Power Flush?

Not every system needs a full power flush. As part of our assessment, we’ll always recommend the most cost-effective solution for your home – whether that’s a simple chemical flush, a full powerflush, or long-term protection with a MagnaClean filter.

System Cleansing & Power Flushing FAQs

How do I know if I need a power flush?

Common signs include radiators that are cold at the bottom but warm at the top, radiators that take a long time to heat up, banging or gurgling noises from your pipes, or a boiler that seems to be running constantly without properly heating your home. If you’re seeing any of these, we can assess your system and advise on the right fix.

How long does a power flush take?

Most domestic power flushes take a day, depending on the size of your system and the number of radiators. We’ll always confirm timings and cost before starting any work.
