Are your radiators failing to heat evenly? Is your boiler making strange noises or running inefficiently? If your central heating system is showing signs of wear, it could be suffering from internal sludge and corrosion. At PHS Engineers Ltd, we provide expert power flushing services across Hertfordshire, helping homeowners and businesses restore the efficiency, warmth, and reliability of their heating systems.
Whether you’re in St Albans, Watford, Hemel Hempstead, or a surrounding village, our Gas Safe Registered engineers are trusted throughout Hertfordshire to deliver fast, effective, and mess-free power flushing solutions that make a noticeable difference.
Over time, all central heating systems accumulate internal debris—sludge, rust, and scale—that clog radiators, damage pumps, and cause uneven heat distribution. These build-ups silently reduce your system’s efficiency, increase your energy usage, and shorten your boiler’s lifespan.
A power flush uses high-velocity, low-pressure water mixed with specialist cleaning chemicals to dislodge and remove this build-up. It clears every part of your system—radiators, pipework, and boiler—restoring optimal performance without dismantling your heating infrastructure.
The outcome? Warmer rooms, reduced energy costs, quieter boilers, and longer-lasting heating equipment.
Many of our Hertfordshire customers come to us after noticing some or all of the following:
These are classic indicators that your system is suffering from internal circulation issues—and that a power flush is urgently needed.
