FAQ's

.Are you considering upgrading your home heating system, curious about the most efficient radiators or want to understand the cost of buying a new radiator? Then take a look at our FAQs below, which answer some common questions about central heating radiators.

 

What are central heating radiators?

Central heating radiators are integral components of a heating system, working to spread warmth throughout your home. They work by using hot water to heat up and then pass that heat into the air of a room. Convector radiators are connected to your central heating system and keep cycling hot water from a boiler through them. This ensures that each room stays consistently warm. Central heating radiators are easy to set up and control, with valves and systems that regulate temperature, making heating efficient.

 

What is the most efficient radiator for central heating?

The most efficient radiators for central heating depend on factors like how long they take to heat up, their energy consumption and their impact on the environment. Aluminium radiators are often considered to be particularly efficient, as they heat up quickly and efficiently, potentially saving up to 15% on energy compared to other types. They also use less water, which means lower energy bills. Other radiator types, like double panel radiators and electric radiators, offer their own advantages, such as powerful heat retention and precise temperature control. However, keeping your central heating system well-maintained is important, regardless of the convector radiator you choose.

 

How much is a new central heating radiator?

Different types of central heating radiators have different prices; for example, designer models can cost as much as £1,000. Basic convector radiators without installation will be much cheaper, starting at under £80 for a small single panel radiator. It's important to consider factors like the size of the radiator and compatibility with pipe fittings, as these can affect the overall cost of the job. If you're considering adding an extra radiator or upgrading your existing ones, the costs will of course vary based on the complexity of the job.
