Hey guys,I used too have a white knight A CLASS dryer,the uk's first 'A' rated dryer.In order for it to be A rated you had to press the energy button.The heat would be very minimal,taking up to 6hours to dry a load of cottons,more for towels.It was a sensor dryer in which you set how dry you require you want your load.You load your clothes and just press start.It lasted for about 6years,I used the A class function once!!!Ive now got an Indesit that I use the cooler function instead of hot for a little bit longer dry time.The smell of softener lasts so much more,theyre softer and have noticed a reduction in bills for dryer usage.Hope this helps.!!!!
