'I'm an energy expert and this is why you shouldn't paint your radiator black'

Andy Kerr, the brains behind BOXT, said some attempts to save cash could actually end up costing more

While some people paint their radiators black to match the décor, others believe it could help them save energy. But an expert has warned it was just a myth that darker radiators would boost heating efficiency.

In light of Ofgem's recent 10 per cent price cap increase, many people were looking for cheaper ways to stay warm this winter. But Andy Kerr, the brains behind BOXT, said some attempts to save cash could actually end up costing more.

Andy debunked some of the biggest energy-saving myths - and dismissed the idea that black radiators would keep homes warmer, the Express reports. He said: "There is a misconception that painting radiators black, or any other dark colour, will enhance their heat radiation efficiency. Dark surfaces, like black, tend to absorb heat and energy, while white surfaces reflect heat."

He said a better option would be to use reflective materials, adding: "Consider placing reflective panels behind the radiators that sit on external walls to prevent heat loss through the wall and to redirect heat back into the room."

People also have various thermostat methods and techniques when it comes to heating their home. Some prefer to maintain a low, constant temperature, while others will have the heating on at full blast for short periods of time.

Offering his thoughts, Andy said: "The thermostat in your heating system controls the desired temperature in the room, not the rate at which the room heats up. The most efficient way to conserve energy and, consequently, save money in the long term, is to have your heating active only when necessary."

He said as energy inevitably leaks from any building, it was more economical to heat homes only when needed. Andy said utilising a timer could be incredibly beneficial as it allowed the thermostat to manage the heating system efficiently, turning it on and off to maintain the set temperature.
