THE cold nights seem to be sticking around and self-heating mattress toppers are a great energy-saving way to keep warm.That's because they work by reflecting your body heat back at you, this is done through a layer of foil within the topper.
The topper was a bit firmer and wasn't as soft as the branded alternative, which meant it didn't feel quite as cosy. Bear in mind though that both of these two gadgets do come with a running cost, but it's pretty low at around 3p an hour. Most DIY stores sell foam lagging, which can be cut to fit the pipes and fixed in place with insulation tape.
You can pick up two rolls on Amazon or just £1 for a metre, all you have to do is cut off the amount you need and peel off the film and stick it on where you need it.You don't have to fork out buying a full-sized gadget, you can opt for a mini one instead.
