If your central heating is not working properly, it could be anything from a simple thermostat setting to a major system fault. Cold radiators, uneven heating, noisy pipes, and high energy bills are all signs that something is wrong with your heating system.

Voltrade heating engineers in Deal diagnose and repair all types of central heating problems. Our AI analyses your symptoms before the visit so the engineer arrives with a clear picture of the likely fault.

Common central heating problems

The most common heating issues in Deal homes include radiators cold at the top (air trapped, needs bleeding), radiators cold at the bottom (sludge build-up, may need a power flush), some radiators hot and others cold (system needs balancing), heating comes on but only lukewarm (pump failure or low system pressure), and thermostat not controlling the heating properly (wiring fault or faulty thermostat).

FAQ

Is my heating system too old to repair?

Central heating systems can last 20 to 30 years with proper maintenance. If yours needs frequent repairs, the boiler is over 15 years old, or radiators are badly corroded internally, a full system upgrade may be more cost-effective.

Why are my radiators cold at the bottom?

Cold at the bottom with warm at the top usually indicates sludge and debris buildup inside the radiator. This restricts water flow through the lower section. A power flush clears the system, or individual radiators can be removed and flushed.

Why is one radiator not working?

A single cold radiator is usually caused by a stuck thermostatic valve, an airlock, or sludge blocking the flow. Try bleeding the radiator first. If that does not work, the TRV head may need replacing or the radiator may need flushing.

What is central heating balancing?

Balancing means adjusting the flow through each radiator so they all heat evenly. Without balancing, radiators nearest the boiler get too hot while those furthest away stay lukewarm. It is done by adjusting the lockshield valve on each radiator.

How do I bleed a radiator?

Turn off the heating and wait for radiators to cool. Use a radiator key to turn the bleed valve at the top of the radiator anticlockwise until air hisses out. Close the valve when water appears. Repressurise the boiler if the pressure drops.
