Contrary to what some people are saying, the Eco wash does not use more electricity and water. I listened to a consumer programme and they were discussing it with an expert. I use the one hour programme. I like to be there when it's working and always go straight away and dry the bottoms of the mugs, etc. off so everything dries properly.
As for Terry Wogan leaving a tumble dryer on and going to bed, that's crazy, as in the morning the clothing, or whatever was in there would be in a heap and very creased. (Miss Terry Wogan, loved his Janet and John stories, he had the talent to cheer people up, he always managed to make me smile). Tumble dryers are good at removing creases if you remove the items quickly. I don't have one. Couldn't afford the extra cost of electricity and don't have any room for one.
