Signs Your System Needs a Power Flush
Several symptoms indicate your central heating system has accumulated sludge and requires power flushing. Cold spots on radiators, particularly at the bottom, suggest sediment buildup preventing proper heat distribution. If your boiler makes banging or kettling noises, or your radiators take longer to heat up than they used to, these are clear warning signs. Other indicators include:
- Discoloured water when bleeding radiators (brown or black indicates sludge)
- Slow warming of your heating system when turned on
- Cold spots on radiators, particularly at the bottom
- Unusual noises like gurgling or banging from the boiler or radiators
- Frequent boiler breakdowns or error codes
- Higher than usual energy bills despite normal usage
The Power Flushing Process
Our power flushing service uses specialist equipment to circulate cleaning chemicals through your heating system at high velocity. This process dislodges and removes years of accumulated sludge, rust, and debris without dismantling your system. We connect our power flushing machine to your heating system, add cleaning agents, and methodically flush each radiator until the water runs completely clear. The process typically takes a full day depending on system size.

Benefits & Results
After power flushing, your heating system operates as efficiently as when it was first installed. Radiators heat up faster and more evenly, reducing the time your boiler needs to run and lowering your energy costs. The removal of corrosive sludge extends your boiler’s lifespan and reduces the likelihood of breakdowns. Your entire home reaches comfortable temperatures more quickly, and your heating system runs quieter without the banging and gurgling noises caused by debris buildup.
