Our Process
How It Works
System survey & risk check
A Gas Safe engineer (Martyn) inspects the system, identifies radiators with cold spots, checks magnetic filters and notes boiler/warranty needs before any work starts.
Powerflush & chemical treatment
Attach a high‑flow powerflushing machine, circulate cleaning chemicals and reverse flow through radiators to dislodge sludge; capture and remove debris using inline magnetic filters.
Balancing, inhibitor and report
Re‑balance radiators, fit or recommend a magnetic filter if needed, dose long‑term inhibitor, and provide a written report with before/after checks and maintenance advice.
Benefits
Why Choose us for Powerflushing?
Restores heat and reduces breakdowns
Powerflushing removes the black iron oxide and sludge that cause cold spots, kettling and early boiler failures, improving circulation so radiators heat evenly and boilers work less hard.
Safe, compliant work by Gas Safe engineers
All powerflushing work is carried out by Gas Safe‑registered engineers with manufacturer experience (Baxi, Vaillant, Viessmann, etc.) and covered by £5 million public liability insurance.
Local, practical service with clear advice
Based in Poringland, Norwich Heating Services offers fast local response, honest recommendations (filters, inhibitors, radiator replacement) and clear written reports after every job.
What a powerflush does: Over years of use central heating systems collect rust, magnetite (black iron oxide) and other debris that sit in radiators, valve bodies and the pipework. A professional powerflush uses a high‑flow pump, approved cleaning chemicals and targeted flow reversal through each radiator to loosen and remove that debris. We capture solids with inline magnetic filters and either flush to waste or cart away captured sludge, leaving the system clean and circulating properly.
How Norwich Heating Services approaches the job: Martyn carries out a full pre‑work inspection to protect boiler warranties and check for vulnerable components. During the flush we monitor water quality and temperature, dose a long‑term inhibitor at completion and test for trapped air, pressure stability and radiator balance. You get a written before/after report plus our recommendation on fitting a magnetic filter or TRV replacement where necessary.

FAQ
Frequently Asked Questions
Common signs are cold spots on radiators after bleeding, noisy boiler kettling or gurgling, slow warm‑up times and magnetised copper pipework. If several radiators are cold or the boiler trips frequently, a powerflush can usually diagnose and clear the problem.
