If you're reading this article, it's probably because you're thinking of buying a new radiator for your home and you've noticed that many of the radiators on the market and made of aluminium, but that they're also choices for alternative materials, such as cast iron and stainless steel.
This may have led to some confusion about which type of material is better than the other and consequently you want to find out more about the reason why aluminium is so popular when it comes to making radiators. Today, we are going to explore this topic in depth.
Under most circumstances, aluminium is generally the best choice of material because it has so many positive features that make it ideal for use as a radiator.
The heat output of aluminium radiators is just right- it’s the Goldilocks material of radiators. This is because its heat output is slow and steady. It doesn't heat up so fast that you lose the rapidly and it doesn't retain the heat within the radiators so that it is harder for the heat to escape. It has a sweet spot where it distributes heat after steady and even rate and pace.
Cast iron is fairly good at emitting heat. However, because it is thicker, it can take a long time for the heat leave the radiator that makes them much less efficient and aluminium. Stainless steel has the opposite problem in that it loses heat too quickly. You might wonder why people bother with stainless steel radiators at all, but it's because once painted or if used as a towel radiator, but provides enough insulation to ensure that the heat leaves at a steady pace, rather than leaving too quickly.
With radiators, efficiency refers to how much heat a radiator will produce when using a standard unit of measurement, which in the case of radiators is a watt. Because of the way that aluminium distributes heat, it is also much more efficient than either of the other two types of radiator in most cases.
There are exceptions, for example with towel radiators, stainless steel radiators much better than aluminium radiators because of the way they distribute heat. However, in a normal room, aluminium radiators generally work the best in terms of efficiency.
Cast iron is also highly efficient, but they generally work better with central heating systems that have a timed mechanism, rather than an ad-hoc mechanism, the latter refers to a responsive system where you turn it on and off according to how you feel in the moment rather than relying on a timed thermostat.
You might not be aware that weight is quite important when it comes to radiator. There are two issues here. First, lightweight radiators are easier to install because it's easier to carry and manoeuvre into place. Second, radiators attached to the wall, and the heavier they are the more pressure they place on the wall so the life of the radiator, the better it is for structural integrity of your home.
