Radiators & power flushing

Cold radiators, banging pipes? Usually a balancing job, not a new boiler.

We diagnose the system properly before recommending a flush, replacement or rebalance. Most cold-radiator calls are sorted in a single visit.

What we do

Heating-side work, from one radiator to the whole loop.

New radiator installations

Properly sized for the room. Old radiators removed and recycled. TRVs added where they make sense.

Radiator replacements

Like-for-like or upgrades. Tidy pipework. Bled, balanced and tested before we leave.

Full power flushes

Magnetite cleared, fresh inhibitor added, system balanced top to bottom. Magnetic filter fitted as standard.

Chemical cleans

For systems where a full power flush is not appropriate. Less aggressive, longer dwell, same end result.

System balancing

Every radiator heating evenly. Often resolves "cold radiator" calls without a flush.

TRV upgrades & smart valves

Thermostatic radiator valves replaced. Smart radiator valves zoned with your heating controls.

The promise

We will not sell you a flush you don't need.

Power flushing is the right answer about 30% of the time we are called for cold radiators. The other 70% is balancing, a stuck pump, a failed valve or fresh inhibitor. We tell you what your system actually needs.

FAQs

Common radiator & flushing questions.

Can't see your answer? Call 07708 089515.

Only if your system shows the signs — cold spots at the bottom of radiators, short-cycling boiler, kettling sounds, magnetite (black sludge) on the filter. We test the system first and tell you straight.
