Central Heating Power Flushing in St Leonards-on-Sea

Feel each radiator when the heating is on. Cold patches at the bottom or middle while the top is hot point to sludge. Other giveaways are radiators that need bleeding every few weeks, dirty water when you do bleed them, and a boiler that has become noisy. Any of those and it is worth getting the system looked at.

Mostly magnetite, a black iron oxide sludge produced as steel components corrode inside the system, along with limescale and general debris. It settles wherever water moves slowly, which is usually the bottom of radiators and low pipe runs, blocking heat and restricting flow.

Price is based on the number of radiators and the condition of the system, and for most homes it comes to a few hundred pounds. You get a fixed written quote before we book the job in, and the price we quote is the price you pay.

Yes. We flush systems in flats and conversions across St Leonards regularly. We will need access to the boiler and all the radiators on your circuit, and we take care to contain water and protect communal areas. If your flat shares any heating infrastructure we will check the setup first.

Plan for most of a day. A small flat with a handful of radiators can be done in a morning, while a large house with a badly sludged system can take eight hours or more. We confirm a realistic timescale when we see the system.

It is the best time to do it. A clean system heats the house faster and uses less gas through the coldest months, and you avoid discovering a failing system in December when every heating engineer in East Sussex is flat out. Autumn bookings are popular, so it pays to plan ahead.

If the noise is kettling, which is caused by scale and sludge on the heat exchanger making water boil locally, then a flush usually cures or greatly reduces it. If the noise has another cause our Gas Safe engineers will diagnose it while we are there.

Always. Corrosion inhibitor is what keeps the system clean after we leave, coating the internal metal surfaces to slow rust formation. We dose the system as the final step of every flush, and we recommend having the level checked at each annual boiler service.

We stop, show you the problem and talk you through the options before doing anything else. Occasionally a corroded radiator or valve that was already on borrowed time shows itself during a flush. As plumbing and heating engineers we can usually repair or replace it there and then if you want us to.

Yes, every part of it. We are based next door in Hastings, so St Leonards is home turf for us. We also cover Bexhill-on-Sea and Rye, and emergency callouts are available when heating fails outright.
