What are the most efficient radiators?

Home energy efficiency chart

Running an efficient central heating system in your home is not only better for the environment, it's also better for your heating bill. By using energy-efficient radiators, you spend less on gas trying to heat your home. When inefficient radiators are used, your boiler has to work overtime to produce the same, or even less, heat than the most efficient radiators.

In our guide to the most efficient radiators, we explore not only what the best radiators are, but also give tips on how to keep your radiators running efficiently too. In doing so, we also identify what is the most efficient way to run central heating so that you can minimise your financial output when heating your home, as well as conserving energy to help reduce your carbon footprint.

How to keep your radiators running efficiently

Before buying energy-efficient radiators, it's a good idea to know how to get the most of your final choice. Doing so ensures that you keep your radiator working better, for longer. To do so, it is a good idea to flush and bleed your radiators regularly.

There can be a fair amount of sludge build up in your central heating system over time. It comes from minerals in the water as well as rust that occurs within the pipes. It can cause a headache for the efficacy of the radiator as it means hot water and heat cannot flow through the system as it should. To get round this problem, simply flush the system by opening the bleed valve. It is recommended to turn the heating off first and put a sheet or towel underneath to stop any marks occurring.

What is the most efficient way to run central heating?

Look at the pipework

Think about insulating any naked pipework on your radiators, as this means that only the hottest water actually gets to your radiator - heating your room more efficiently. Insulating your pipework needs to be done safely, so it can be a good idea to ask a professional. 

Install a thermostat valve

Radiator valves are a good way to optimise your central heating so it runs efficiently. More specifically, thermostat valves are helpful as they mean you can turn up or down each individual radiator. The result is you can adjust each radiator to what the room requires. Some rooms will have more draughts than others. Or some may simply be used a lot, where others aren't. Turning down the radiators in the rooms that are used least can really help your final heating bill. 

The most efficient radiators

There are a number of types of radiators that are very efficient when it comes to energy. Here, we identify them so you can pick an option that best suits your needs.

Electric radiators

Generally speaking, electric radiators will be an 100% energy-efficient radiator. Because all the energy used is converted into heat - no energy is lost. The most energy-efficient electric radiators are therefore ones that are the right size for the room it needs to heat. 

Aluminium radiators

The majority of radiators in the UK are made of steel. However, aluminium radiators are far quicker to heat up making them more energy efficient. They need less water to heat up the panel too, creating further energy efficiencies. 

Dual fuel radiators

Dual fuel radiators allow homes to switch between gas or electricity to heat a radiator. That helps with energy efficiency, particularly in the summer months, as it means you can more easily switch on or off parts of your entire central heating system. Dual fuel radiators tend to be towel rails, which are used year round unlike other radiators in other rooms which are not needed in the summer. 

Double panel radiators

Double panel radiators can be fairly energy efficient because they have two panels instead of just the one. That massively increases their surface area, making them efficient at heating a room. They're a good space saver too.

Underfloor heating

Underfloor heating can be a good option when looking at improving the energy efficiency of your central heating. By heating rooms from the floor up, there are no cold spots and it heats the air where it is coolest - making the most of convection. The most efficient underfloor heating is often argued to be electric - though this is expensive to run. It is also available in a 'wet' system - which heats up water with a gas boiler to pump around pipes in the ground. 

Buying the most efficient radiator for the space you need to heat is one of the easiest and quickest ways to reduce your energy bill. Importantly, it is better for the environment too as it can reduce your household's carbon footprint. Check out our range of energy-efficient radiators today.
