What is a central heating system and how does it work?

A central heating system provides heat throughout your property using a single heat source normally a boiler. The boiler heats water and pumps it through a network of pipes and radiators or underfloor heating. As the water circulates, it releases warmth into each room, then returns to the boiler to be reheated.

Most systems are closed-loop, meaning the same water is reused again and again. This makes it efficient and easy to control. The system is managed by thermostats and timers, which tell the boiler when to turn on or off based on the temperature you set.

When properly maintained, a central heating system keeps your property evenly warm, prevents damp, and helps control energy use.

How often should I service my central heating system?

You should service your central heating system once a year. This ensures that everything the boiler, pumps, valves, pipework and controls is working efficiently and safely. Annual servicing helps prevent breakdowns, maintains good water circulation and keeps your heating bills down.

During a service, a qualified engineer checks for leaks, corrosion and gas safety issues. They’ll test boiler performance, inspect the pressure and make sure radiators are heating evenly. If needed, they’ll top up corrosion inhibitor to protect against sludge buildup.

Regular servicing can also highlight minor issues before they become expensive repairs. For landlords, it’s a legal requirement to ensure the heating and gas systems are checked annually by a Gas Safe registered engineer.

Skipping maintenance might save money short-term but often leads to poor performance, noisy pipes, or even boiler failure. Keeping to yearly servicing is the best way to extend the life of your heating system and ensure it runs safely all year.

Why are my radiators not heating up properly?

If your radiators aren’t heating up as they should, the problem is usually caused by trapped air, sludge buildup, or circulation issues. Cold spots at the top of a radiator often mean air is trapped inside bleeding the radiator usually solves it.

Cold spots at the bottom, however, indicate sludge. Over time, rust and debris collect in the system and settle in the radiators, restricting water flow. This makes some rooms colder than others and forces the boiler to work harder.

Other possible causes include a faulty pump, blocked pipes, or radiator valves stuck closed. In some cases, the system needs balancing so heat is distributed evenly to every radiator.

A heating engineer can quickly diagnose the issue and recommend a fix anything from bleeding a few radiators to carrying out a powerflush to clean the system. Once circulation is restored, your radiators will heat evenly again and the system will run more efficiently.

How much does it cost to repair central heating in London?

The cost of central heating repairs depends on the type of fault and the parts involved, but what really matters is getting a proper diagnosis. Common problems include leaking radiators, low pressure, faulty pumps, broken valves or boiler faults.

When you call a professional heating engineer, they’ll inspect the system to find the root cause before suggesting repairs. In many cases, small issues like airlocks or jammed valves can be fixed on the spot. More complex faults, such as a pump replacement or major pipework repair, may take longer.

What’s important is using a qualified engineer who can do the job safely and correctly. Proper repairs prevent repeat issues, improve energy efficiency, and reduce the strain on your boiler.

What’s the difference between a combi boiler and a system boiler?

A combi boiler heats water directly from the mains whenever you turn on a tap or shower. It doesn’t need a separate water tank or cylinder, which makes it compact and ideal for smaller homes or flats.

A system boiler, however, works with a hot water cylinder. It stores hot water so that multiple taps and showers can be used at once without losing pressure. This setup suits larger homes or properties with higher hot water demand.

Combi boilers are great for space saving and energy efficiency, as they only heat water when needed. System boilers are better when you need consistent water pressure in multiple bathrooms.

Both have their benefits, and the right choice depends on your home size, water pressure and usage. A heating engineer can assess your setup and recommend which system would work best for you.

Can I upgrade my old heating system to a modern one?

Yes, older heating systems can almost always be upgraded. Modern systems are more energy-efficient, reliable and easier to control. Upgrading may involve fitting a new condensing boiler, replacing outdated radiators and installing modern controls such as smart thermostats or thermostatic radiator valves (TRVs).

An engineer will inspect your current setup to see what needs updating whether it’s the boiler, pipework, or controls. In some cases, a powerflush is carried out before installation to clean the system and prevent debris from damaging the new components.

Upgrading can improve heating performance, lower energy bills and reduce carbon emissions. It also makes your system safer and less likely to break down during winter. Modern boilers and controls give you better temperature management.

Why is my central heating making banging or gurgling noises?

Noises like banging, clanging, or gurgling are often signs of air trapped in the system, sludge buildup, or a circulation problem. Air can get into the pipes or radiators and cause bubbling or gurgling sounds as water passes through.

Banging or knocking noises, known as “kettling,” can happen when limescale or sludge restricts flow in the boiler or pipes. The water overheats, turns to steam and causes vibrations and noise.

If your heating system is noisy, it’s best not to ignore it these sounds usually mean your system isn’t running efficiently. An engineer can bleed the radiators, balance the system, check pump speed, or carry out a powerflush to clear the buildup.

Once the problem is sorted, your system should run quietly and heat more effectively.

Is it safe to repair central heating myself?

No, it’s not safe to repair a central heating system yourself. Boilers and heating systems operate under high pressure and, in most cases, use gas. Working on them without proper training or certification can be dangerous and even illegal.

Gas-related work must be carried out by a Gas Safe registered engineer. They have the tools, knowledge and safety checks needed to repair systems safely and legally. Attempting DIY repairs risks gas leaks, electrical faults, or damage to the system that could lead to costly repairs later.

If your heating isn’t working properly, turn it off and call a qualified engineer. It’s always safer and cheaper to get it repaired professionally than to take the risk yourself.

How long does it take to install a new central heating system?

Installing a new central heating system typically takes between 3 and 7 days, depending on the property size, number of radiators and how much of the old system needs replacing.

A straightforward boiler swap might only take a day or two, while a full system replacement with new pipework, radiators and controls takes longer. Engineers will remove the old components, fit the new boiler, connect all pipework and test everything thoroughly before signing off the job.

Proper installation is important it ensures the system runs efficiently, safely and lasts longer.

Do I need to power flush my central heating system?

Yes, a powerflush is often necessary if your system has cold spots, poor circulation or noisy operation. Over time, rust and sludge build up inside the pipes and radiators, blocking flow and forcing the boiler to work harder.

A powerflush clears this debris using specialist equipment and cleaning chemicals, restoring full water flow and efficiency. It’s especially recommended before fitting a new boiler to avoid contaminating the new system.

You don’t need to powerflush every year, but doing it when your system shows signs of sludge or before a major upgrade helps protect your investment and extend the life of your heating system.
