There’s a common assumption that the colour of the radiator has a significant impact on its performance and efficiency. In the course of this article, we are going to explore this assumption in-depth and provide you with a more realistic view.
Sometimes, the assumption is correct, but other times, it is incorrect. If you think that it’s always true, then you might be missing out on buying some radiators that fit your space better than the traditional white radiators do.
Does Colour Affect the Way Your Radiators Work?
The answer really depends. When you compare matte coloured radiators with traditional white radiators, then there is some difference in performance. The darker radiators will retain slightly more heat than the white radiators will retain. This means that they put out less heat. In turn, this means that you pay more to heat the room when you’re using a coloured radiator rather than a white radiator.
However, the difference is marginal. At the very most, a coloured radiator is going to cost you between 1% and 10% more to run than a white radiator will cost. If your energy bills match the average in the UK, which is around £900 a year, you’ll be paying between £9 and £90 extra on top of that.
Spread out over the year you’ll be paying at most an extra £7.50 a month. Therefore, your decision should be based on whether your interior decor is worth £7 50. For some people, that is more than affordable, for others it’s too expensive.
There’s also the environmental impact because an extra £90 worth of energy is going to have more of an impact on the environment. And this is based on the worst case scenario. Many people believe that the efficiency difference is as little as 1%, which is marginal.
Forgetting money and forgetting the environment, you might be worried that the radiator won’t produce enough heat for the room if it isn’t as efficient. This isn’t the case. The BTU rating of a radiator is how much heat it will put out regardless of its colour. If you choose a radiator that has the correct BTU for the space, then you will be able to keep the room warm.
There is one exception in terms of colour, and that is silver radiators with a reflective finish. These radiators are highly conductive, meaning that they kick out their heat quickly. In comparison to a white radiator, they will kick out heat much faster (and a coloured radiator would be much slower than a white radiator).
This means that they are inefficient in a different way. The reason for this is that silver radiators are intended for use as towel radiators or places to dry your clothes. The addition of the material on top of the radiator serves to act as an insulator, which then renders it efficient.
