How our power flushing works.
1. Pre-flush survey
Radiator-by-radiator temperature readings logged so we can prove the improvement.
2. Power flush
High-flow pump connected; chemical cleaner and magnetic filtration pull out sludge and rust.
3. Inhibitor & filter
Fresh corrosion inhibitor added and a MagnaClean fitted to keep the system clean long-term.
4. Final test
Re-read every radiator. You'll see hotter tops, hotter bottoms, faster warm-up.

FAQs
Power Flushing — your questions answered.
Do I really need a power flush?+
If radiators are cold at the bottom, the boiler is noisy or your heating is slow to warm up, yes — sludge is the cause in 9 out of 10 cases.
How long does a power flush take?+
Most 3–4 bed homes are completed in 4–6 hours. Larger systems may run into a second visit.
Will a power flush void my boiler warranty?+
The opposite — most manufacturers require the system to be clean. Worcester Bosch and Vaillant specifically recommend power flushing on system changes.
