Very efficient, and sounds a bit like a Tube train!
5/5
Finally managed to bag myself one of these, after they were constantly out of stock due to supplier issues. It was to replace an ageing, energy-hungry standard condensing tumble dryer that I wouldn't be able to afford to run at all due to energy prices.
I calculated that by buying this one, with the amount of tumble drying we do, it would break even after the first year of use, and so far it's definitely using a fair chunk less electricity than the last machine, and isn't taking any longer to dry, so I do think it'll pay for itself very quickly, and I don't have to feel quite as guilty using it.
