Power Flushing in Gillingham

What Happens During a Power Flush?

A power flush is a thorough cleaning process for your entire central heating circuit. We connect a specialist pump unit to your system and force a high-strength cleaning chemical through every radiator, every length of pipe, and your boiler's heat exchanger. The chemical breaks down the iron oxide sludge, limescale, and corrosion deposits that have built up over the years.

Each radiator is flushed individually until the water running through it comes out clean. Once the entire system has been cleared, we drain the dirty water, refill the system with clean water, and add a chemical inhibitor to protect against future corrosion.

Gillingham sits in a hard water area, which means limescale forms more quickly inside heating systems compared to properties in soft water regions. This limescale coats the internal surfaces of your boiler's heat exchanger and your radiators, acting as an insulating layer that forces the boiler to burn more gas to produce the same amount of heat. A power flush removes this layer and can improve heating efficiency by up to 25 per cent.

Warning Signs You Need a Power Flush

• Radiators cold at the bottom but warm at the top
• One or more radiators not heating up at all
• Boiler making kettling, banging, or gurgling sounds
• Heating system slow to reach temperature
• Dark water when you bleed your radiators
• Boiler cutting out or showing fault codes

Gillingham Properties and Heating Systems

Gillingham's diverse housing stock means a wide variety of heating systems are in use across the town. The older properties near Gillingham High Street and around the Green Street area often have heating systems that were retrofitted decades ago, sometimes using small-bore or microbore pipework. These narrow pipes are particularly vulnerable to sludge blockages because it takes less debris to restrict the flow.

The large post-war estates in Twydall and Parkwood feature mainly semi-detached and terraced houses, many of which had their central heating installed in the 1970s or 1980s. While the boilers in these properties have usually been replaced at least once, the original pipework and radiators often remain. After 30 to 40 years of use, these systems accumulate significant quantities of sludge.

The ex-Ministry of Defence housing near Brompton Barracks presents its own characteristics — these properties were often built to a standard specification with heating systems that may have been maintained to varying degrees depending on ownership history.

Wherever your property sits in Gillingham, if the heating system has not been power flushed in the last 5 to 8 years, it will almost certainly benefit from one.
