Power Flushing
About This Service
Reliable Power Flushing for Period Homes
One agreed price covering the survey, the powerflush, professional chemicals and a full post-service report, with no hidden extras. Our Gas Safe registered engineers use high-flow powerflushing rigs and magnetic filtration to remove sludge, magnetite and debris that block radiators and heat exchangers. We work on Victorian terraces, townhouses and modern semis across St Albans and neighbouring towns. After the flush we add corrosion inhibitor, rebalance the system and leave a clear service record.
Our Process
How It Works
Survey and system check
We inspect your boiler, pump and radiators, run diagnostic tests and confirm whether a powerflush is the correct solution. You get a written scope of work before we start.
Powerflush and chemical treatment
Our engineers connect a high-flow powerflushing rig and magnetic filter, flushing the system with professional cleaners, then neutralise and add a corrosion inhibitor.
Balancing, report and aftercare
We rebalance radiators, retest system pressures and leave a clear post-service report. Advice on maintenance and any follow-up work is included.

What a powerflush does: Over time central heating systems collect magnetite, rust and debris that restrict flow, cause noisy radiators and leave cold patches. Powerflushing forces a controlled, high-flow clean through radiators, pipework and the boiler heat exchanger to remove sludge and restore consistent heat delivery.
