My radiators are cold at the bottom — what does this mean?
Cold spots at the bottom of radiators usually means sludge and debris has built up in your system — a powerflush will fix this.
Over time, rust, scale, and sludge accumulate inside your central heating system. This causes:
- Cold spots on radiators (especially at the bottom)
- Noisy boiler or banging pipes
- Slow heating times
- Higher energy bills
- Premature boiler failure
Key Point
A powerflush clears all the sludge from your system and restores full heating performance. Most homes see an immediate improvement in how quickly radiators heat up.
- 1We connect a powerflush machine to your system
- 2High-flow water with cleaning chemicals breaks down the sludge
- 3Each radiator is flushed individually
- 4A magnetic filter is fitted to prevent future build-up
- 5Inhibitor is added to protect the system going forward
