5 Common Central Heating Problems and How a Professional Can Solve Them

A fully functional central heating system is essential for keeping your home warm and comfortable, especially during the colder months. However, like any other system in your home, central heating can develop issues over time. Recognising these problems early and seeking professional help can prevent further damage and ensure your system operates efficiently. At Buxton Plumbing & Heating, we specialise in diagnosing and resolving central heating problems for homeowners in Buxton, Derbyshire. Here are five common issues and how a professional can solve them.

1. Cold Radiators

One of the most common complaints homeowners face is radiators that fail to heat up properly. This issue is often caused by trapped air, sludge build-up, or a malfunctioning valve. If only the top half of the radiator is cold, trapped air is likely the issue. If the entire radiator remains cold, it may indicate blockages or a faulty thermostat valve.

Solution: A professional can bleed the radiator to release trapped air or flush the system to remove sludge build-up. They will also inspect and replace faulty valves to restore full functionality.

2. Noisy Central Heating System

Banging, gurgling, or whistling noises coming from your central heating system can be alarming. These sounds are typically caused by air trapped in the pipes, a failing pump, or kettling, which occurs when limescale builds up in the boiler’s heat exchanger.

Solution: A professional plumber can identify the root cause and take appropriate action, such as releasing trapped air, repairing the pump, or descaling the boiler. Regular maintenance can also prevent these issues from recurring.

3. Boiler Losing Pressure

A drop in boiler pressure can result in reduced heating efficiency or no heating at all. Common causes include leaks in the system, a faulty pressure relief valve, or recently bled radiators without rebalancing the system.

Solution: A professional will check for leaks, repair or replace the pressure relief valve, and re-pressurise the system to ensure it operates at the correct levels. They may also recommend a power flush if the issue is related to blockages.

4. Uneven Heating Throughout the Home

If certain rooms in your home are warmer or colder than others, the central heating system may be unbalanced. This can occur due to incorrect settings on radiator valves, blockages in the pipes, or an undersized pump struggling to circulate hot water effectively.

Solution: A heating professional can balance the system by adjusting the flow to each radiator, ensuring even heat distribution. They may also assess whether the pump or system design needs upgrading to improve performance.

5. Boiler Fails to Ignite

If your boiler refuses to turn on, it could be due to a variety of reasons, including a lack of gas supply, an electrical fault, or a malfunctioning pilot light. Modern boilers may also display fault codes that provide clues to the underlying problem.

Solution: A Gas Safe registered engineer will inspect the boiler, check the gas supply, and test electrical connections. If necessary, they will replace faulty components or reset the system to restore functionality. For safety reasons, it’s important not to attempt boiler repairs yourself.
