With heating bills soaring, everyone is looking for a simple way to cut costs - which is where radiator booster fans could come to the rescue. For those who have never heard of them, these gadgets attach to the bottom or top of the best radiator, drawing in cooler air from the floor, blowing it across the warm radiator surface, and then pushing the heated air quickly around the room. To find out whether these add-ons really work (or whether they're just another gimmick), we asked a heating expert for their opinions and put them to the test on our own radiators.

Moka pots have stayed remarkably consistent since their invention, maintaining the same octagonal silhouette and brewing method across generations. They produce rich, concentrated coffee reliably, but the process demands patience while water heats slowly and pressure builds gradually. Most models sit on stovetops for several minutes burning gas or electricity, which adds up over daily use and feels inefficient for such a simple task.

When you touch objects at the same temperature, the one that feels cooler often has a higher thermal conductivity, leading to greater energy loss from your hand.
