How to fix problems with radiators
Things to check before you turn your heating back on
It's almost time to turn your heating back on - so ensuring that your radiators are working efficiently is a must. During the colder months, you need your whole property to warm quickly and stay that way. Knowing how to fix any minor issues yourself will help your home stay warm, without you having to fork out for an engineer.

While you need a qualified professional to install a central heating system, maintaining them isn’t difficult and most tasks take no time at all to complete. So you’ll only need to call in the experts if something isn’t easily fixed and we’ll help you understand if and when you need to make that call.

As well as teaching you about how your system works, we’ll show you how to bleed your radiator and tackle faults like noisy or cold systems.

How a radiator works:
In a wet central heating system, a boiler heats water before it’s pumped around a circuit of pipes to radiators fitted throughout the house. Each radiator has valves that control the rate at which water flows through it, therefore controlling the amount of time the water spends in the radiator and the amount of heat that is given off. When the water leaves the radiator, it’s piped back to the boiler for reheating.

Some heat is lost from the pipes as the water flows around the system, but this is kept to a minimum by the pipes being very narrow as well as the speed at which the water travels. A well-designed system may have several short circuits radiating from the pump, rather than one large one, to make sure that the last radiator on each circuit heats up just as efficiently as the first.

Q: How can I fix issues with my radiators?

A: Before turning on your heating system, it's crucial to ensure that your radiators are functioning optimally. During colder months, you want your entire property to warm up quickly and stay that way. By knowing how to address minor problems yourself, you can maintain a warm home without the need to hire an engineer and incur unnecessary costs.

While installation of a central heating system requires a qualified professional, maintaining it is relatively simple, with most tasks being quick to complete. We'll guide you through troubleshooting common radiator issues, such as noise or insufficient heat, and teach you essential skills like bleeding your radiator.

Q: How does a radiator work?
Understanding how a radiator works is key. In a wet central heating system, a boiler heats water, which is then circulated through a network of pipes to radiators throughout the house. Each radiator is equipped with valves that control the water flow, determining the amount of time the water spends in the radiator and the heat emitted. After leaving the radiator, the water returns to the boiler for reheating.

While some heat is lost as water flows through the pipes, the efficient design minimizes this loss. Narrow pipes and multiple short circuits radiating from the pump ensure that each radiator heats up as efficiently as the first one.

By following our guidance, you'll be able to troubleshoot common radiator problems, such as bleeding air from the system or addressing issues with valves and thermostats. However, should the problem persist or if you're uncertain about any aspect, it's advisable to seek professional assistance. Their expertise will ensure accurate diagnosis and effective solutions, preventing further complications.

Remember, regular maintenance and timely intervention are essential for optimal radiator performance, keeping your home warm and cozy throughout the heating season.
