I have one too!!!
It's the ultimate no frills dryer! I think it's got a D energy rating, however we tend to cram most of the load in it as we leave jeans and jumpers out, I think it takes around 2.3kw, which is less than most full size dryers. I can never get drying times right, as I've often put things in for 80 minutes and still things are damp, yet other times when I've opened the door mid way the items are totally bone dry.
