Power Flushing in Strood

How Power Flushing Restores Your Heating System

Power flushing uses a high-flow pump and specialist cleaning chemicals to force contaminated water and debris out of every part of your central heating circuit. Our engineers connect the pump to your system and work through each radiator individually, reversing the flow to dislodge sludge from corners and low points where it settles.

The cleaning chemicals — typically Fernox Cleaner F3 or Sentinel X400 — dissolve the magnetite sludge and limescale that coats the inside surfaces of your pipes and radiators. In a hard water area like Strood, limescale is a particular concern. The minerals in Kent's water supply form a chalky deposit on the inside of your boiler's heat exchanger, which acts as an insulating barrier and reduces the boiler's ability to transfer heat efficiently.

After flushing, we refill the system with clean water and add a corrosion inhibitor to slow down future sludge formation. For ongoing protection, we recommend fitting an in-line magnetic filter that captures metallic particles before they can circulate through the system.

Signs Your Strood Home Needs a Power Flush

• Radiators hot at the top, cold at the bottom
• Individual radiators that refuse to heat up
• Loud banging, kettling, or gurgling from the boiler
• The heating system takes noticeably longer to warm up
• Black or brown water when you bleed a radiator
• Boiler frequently losing pressure or displaying fault codes

Why Strood Properties Are Prone to Sludge Build-Up

The older properties along Strood High Street, Knight Road, and the streets around Gun Lane were built during the Victorian and Edwardian periods. Heating systems in these homes are almost always retrofitted, with pipework routed through existing walls and floors. These runs often include low spots where sludge accumulates and is difficult to shift without a dedicated power flush.

The 1960s and 1970s housing along Darnley Road and around the Canal Road area commonly features small-bore pipework, which is more susceptible to blockages than standard 22mm pipe. Even a thin layer of sludge inside 8mm or 10mm microbore pipe significantly restricts water flow and creates cold spots.

Homes on the Frindsbury side of Strood tend to be newer, but even systems installed in the 1980s and 1990s will have accumulated considerable debris after two or three decades. A power flush every 5 to 8 years keeps these systems running cleanly and helps prevent costly boiler repairs.
