Maximizing Energy Efficiency: The Benefits of Aluminium Radiators

Updated: Jun 17

Aluminium radiators can tick a lot of boxes for homeowners. The main benefit of aluminium designer radiators is that they will heat up faster than other materials (and cool down quickly). This is because aluminium is a superconductor and so responds quickly to thermostatic changes. Radiators made from this material are therefore highly efficient and make it easy to control the temperature of your room.

Another benefit of aluminium designer radiators is their light weight. Not only does this make the installation process much easier, but it also makes them suitable for a wide range of projects, as they can be hung on the vast majority of walls.

A further benefit is energy efficiency: less water is required for aluminium radiators to operate compared to others, meaning less demand on the heating system. These radiators also work well with renewable energy sources and systems running on a lower Delta T.

Aluminium is also fully recyclable at the end of its useful life (most aluminium radiators are also made from a large percentage of recycled material!) and although it is slightly more expensive in comparison to other materials such as mild steel, the initial cost is more than covered by the lifetime efficiency savings. This makes aluminium radiators appealing to cost-conscious customers and those looking to reduce their environmental impact.

Increased interest and legislation in the use of renewable energy sources have led to greater use of lower water temperatures in heating systems. Using conventional steel radiators to deliver adequate output for each room can prove difficult, with large radiators needed to achieve output.

One solution is to use aluminium radiators and UK consumers with a desire to use renewable energy are becoming more aware of its inherent benefits, especially in relation to the lower delta T’s delivered with renewable energy.

Aluminium has excellent thermal efficiencies; heating up and cooling quickly, which allows immediate control of the temperature in each room, perfect when combined with thermostatic valves.

Low Water Content;

Their thermal efficiency means aluminium radiators can operate with comparatively lower water content making them perfect for systems that produce a lower water temperature, e.g., heat pumps, or condensing boilers that use methane, gas-oil or wood pellets.

Easy Installation;

The lightweight nature of aluminium makes them easy to handle and suitable for a one-man installation.

Aluminium is incredibly versatile - inherent thermal properties mean lower water content, efficient transfer of heat and efficient temperature control.

British Thermal Units (BTU) is a measure of the output of heat needed to raise the temperature of a room. Determining the correct BTU will help you get the right radiator for your home.
