There a range of materials you can choose from to build your radiators. Below is everything you need to know about one of the most popular.

Many people could overlook the importance of the radiator material. With heat efficiency, radiator positioning and heating unit shape all being influential factors in your homes overall BTU output, the very material you use can be overlooked. With so many materials out there to choose from, it can be difficult to decide which one will suit you and your home. Instead of weighing up the pros and cons of each radiator material side by side, it is far more helpful to explore the positives, negatives and intricacies of the radiator material in greater depth. This will hopefully allow the customer to come to a decision as to which one is right for their needs, instead of being miss sold a product which could ultimately disappoint.

Aluminium Radiators 

Aluminium radiators are found in many homes across the UK, having quickly become one of the most popular materials for heating unit manufacture. Many designer radiators at Great Rads are made from aluminium, alongside all manner of shapes, sizes and energy inputs.

What Is Aluminium?

Aluminium is one of the most abundant metals in the world. Discovered in the 1750’s, aluminium makes up about 8 percent of the earth’s crust. Although it is found in such large quantities, aluminium rarely comes in its solid form. It usually has to be extracted from other metals and rocks through potassium and sodium and the creation of it has been observed in space, created through the nuclear fires of stars when a proton is added to magnesium.

Aluminium has many different applications in the modern world. From aeroplane bodies to bicycles, much of our current metal uses aluminium. It is not surprising then, that radiators are made from the solid and cheap to produce material.

Positives of Aluminium Radiators

So why should you invest in an aluminium radiator? What sets it out from stainless steel and cast iron?

Lightweight Metal

One of the great things about aluminium is that it is a lightweight metal. This makes it a lot easier to transport and install. The lightweight metal makes it perfect for quick installations and creative designs, it being manipulated far easier due to its weight. This is a great benefit for those who require a quick and simple installation which they could do themselves.

Quick to Heat Up

Due to its lightness, aluminium has less atoms within it. When the metal is heated up and the atoms begin to vibrate faster, they find it easier to react with one another and spread the heat. This means that an aluminium radiator heats up far quicker than any other material.

Abundant Quantities

As mentioned above, aluminium is easy to find in the earth’s crust. This pushes down the prices as it is easily sourced and cheaply processed. In the long run, this makes aluminium radiators cheaper to buy, and ensures that you are getting a great value product.


Look at the variety of uses for aluminium: aeroplanes, cars, bikes, pens, trains. So much transportation and infrastructure is made from aluminium, all of it different in design and shape. This is great for the designer radiator market, whether your going for a central heating or electric radiator, aluminium brings a flexibility which allows designers to craft all manner of shapes.


Take warning though, there are a few points which might put you off aluminium. Whilst they are only small queries and will most likely not outweigh the positives, you should still keep it in mind when choosing your radiator.

Quick to Cool Down

Aluminium is quick to heat up, and therefore quick to cool down. This means that they are perfect for short sharp bursts of heat in a smaller room, but might not do the trick for longer periods of time in larger rooms.

Will Sometimes Need Maintenance

Aluminium is a reactive metal, and so will need protection from rust. Whilst most radiators come with a finish or a paint job, you should still keep an eye on the degradation of the metal. Although it is highly durable, aluminium si quite a soft metal, and should be treated with care.
