How often should a central heating system be serviced?

We recommend having your boiler and heating system serviced every 12 months. Annual servicing keeps the system running efficiently, extends its lifespan, and is often a condition of the boiler manufacturer's warranty. It also means any developing problems are caught early, before they become expensive repairs.

Why are some of my radiators cold at the top but warm at the bottom?

This is usually caused by trapped air in the radiator, which can be resolved by bleeding it. If bleeding doesn't help, or if the radiator is cold all over, there may be a sludge build-up in the system or a faulty thermostatic radiator valve. Our engineers can diagnose and fix the issue quickly.

What is a power flush and do I need one?

A power flush is a deep-clean of your central heating system that removes sludge, rust and debris from the pipework and radiators. Signs that you may need one include cold spots on radiators, noisy pipework, a boiler that cuts out frequently, or discoloured water when you bleed a radiator. It significantly improves system efficiency and is often recommended before a new boiler is installed.

Can you add a radiator to an existing central heating system?

Yes. We can add new radiators to an existing system, replace old ones, or reposition them as part of a home renovation. We'll check that your boiler has sufficient output capacity before any additions are made and advise on the best approach for your home.

My heating is on but the house isn't getting warm — what could it be?

There are several possible causes: a boiler working below its rated output, significant sludge build-up in the system, poorly balanced radiators, or inadequate insulation. Our engineer will carry out a systematic check of your boiler, controls, and radiators to find the cause and recommend the most effective fix.

Central heating problems we fix in Shepperton

If you need a plumber in Shepperton for heating faults, we help households across TW17, from riverside homes to family properties near Shepperton Studios. Our work is practical and tidy, with clear advice on what is causing the problem and how to put it right.

Cold Radiators

Cold radiators often point to trapped air, sludge build-up, a faulty pump or a circulation issue elsewhere in the system. Our engineer checks the system properly, bleeds and balances where needed, and looks for the underlying cause so the heat reaches every room evenly.

Power Flush Service

If some radiators stay lukewarm or heat up slowly, sludge and debris may be restricting flow through the system. We use power flushing to clear the pipework and radiators, which can improve circulation, reduce strain on the boiler and help the whole system run more efficiently.

Radiator Replacement

Old radiators can be undersized, corroded or slow to heat, especially in larger rooms or older village cottages. We replace tired units with the right size and style for the property, then test the system so the new radiator performs properly from the start.

Smart Heating Controls

Smart thermostats and heating controls can make it easier to manage temperatures in busy homes and lower wasted heating. We install and set up controls correctly, then show you how to use schedules, zones and temperature settings so the system matches your routine.

Noisy Heating Pipes

Noisy pipes can be caused by air in the system, loose pipework, high water pressure or heat expansion in older runs. We trace the source of the sound, secure anything that is moving and adjust the system where needed, so the heating runs more quietly and reliably in homes across Shepperton and Sunbury-on-Thames.

TRV Repairs And Fitting

Thermostatic radiator valves, or TRVs, help control the temperature in each room, but they can stick, seize or fail with age. We repair or replace faulty TRVs and make sure they are fitted and balanced correctly, so each radiator responds as it should.

Expert Advice

“Central heating in Shepperton works best when the radiators, valves and controls are balanced as one system. I pay close attention to cold spots, noisy pipes and uneven heating, because those are usually the first signs something is out of tune.”
