The money saving expert says that the simple gadget could potentially slash hundreds off your heating bill every year. His advice comes as temperatures in the UK have left many households struggling with keeping warm and drying their washing. Several people have also fallen ill and concerned with mould as a result of not being able to afford to put the heating on. In the latest episode of the Martin Lewis podcast, the popular TV expert offered a 7p solution to the problem. He said it requires people to make a small investment first, but after that, you'll start saving money, reports the Mirror .

He explained that as long as you factor in the cost of buying one in the first place, it will guarantee lower electricity bills. He added: " Many dehumidifiers have different wattages, the one I checked out was 200 watts (w). Once we know it’s 200w and we know a kilowatt (kw) is 1,000w, which is how electricity tends to be priced, we know this is a fifth of a kilowatt and you pay roughly 34p per kw per hour. "A fifth is 7p so you’re going to pay roughly 7p per hour to run a dehumidifier at 200w assuming it uses full power the whole time, which is generally far, far cheaper than putting the heating on. If a dehumidifier does work for you it will definitely have lower electricity bills but of course you do have the initial capital outlay of buying a dehumidifier and see how that works for you.
