I wanted to try out a "heat source" tumble dryer, because it was said to be much better for the environment. but it tuns out its significantly better for your budget also, which is logical if you consider how it works. the dryer uses a lot less electricity its basically just a fridge in reverse! most people don't realise how much a normal tumble dryer costs to run. If your tumble dryer is running one hour a day, which isn't unusual in a family these days in the winter, its equivalent to having your kettle on for an hour! take a look at your smart meter when running a heat source dryer like this - it hardly moves. Very smart move! great machine, good price.
