What are the most energy efficient radiators?

Aluminum radiators are considered to be the most energy efficient option. Due to their strong thermal properties, they retain heat for longer periods of time, keeping your living space warm even after turning off the heating. Additionally, aluminum radiators are lightweight and easy to install, compared to other materials such as cast iron. They also tend to be more cost-effective, which can help save on energy bills while still maintaining a comfortable home temperature. Overall, aluminum radiators are a great choice for those looking for energy efficiency and comfort in their heating system.

Are electric radiators cheaper to run than gas?

Yes, electric radiators can be cheaper to run than gas and are becoming an increasingly popular choice for heating homes due to their cost-efficiency. Not only do they require less upfront installation costs compared to gas, but they also offer cheaper running costs, since 100% of the electrical energy is converted into heat energy. With the ability to turn them on and off in individual rooms when needed, you have more control over your energy usage and can lower your monthly bills.

How to keep your radiators running efficiently?

Regularly bleeding your radiators is essential to keep them running effectively and efficiently. The process takes only a few minutes and can be done with a radiator key, which you should be able to purchase from your local DIY store. 
Flushing the system is also important as it helps remove any built-up sludge and debris. This can naturally build up over time and lead to the corrosion of vital components within the system. It’s important to flush out these contaminants in order to keep your radiators running properly. An experienced plumber can do this for you if needed, or alternatively, there are kits available which allow you to flush the system yourself.
