We have purchased the dryer Bomann us three weeks ago, and I have to say we are really surprised. We have a commercial 5kg washing machine and now to halt the 6kg dryer. The supplied exhaust hose was a bit short, so we still had to buy a longer us, but that's in every apartment different. Indicated's a consumption of about 4 kWh. We then measured by using a flow meter to control costs, how much is the actual consumption. We have, as I said a 5kg washing machine, and a full load of laundry in the dryer consumes then only an average of 2.7 kWh. So much more economical than expected (measured in the cotton program). It's also nice that the dryer has moisture sensors and thus the dryer automatically adjusts time and off automatically when the clothes are dry. As a single point of criticism I would attach processing the lint filter, the material is not particularly high and is a bit tricky to clean. But if you got the hang of once out, then it is also fast and without problems. We can only recommend the dryer, mainly because of the dryer performance and yet low power consumption.
Update 04.01.2012 After a few years in use, the performance of the dryer has yet very removed. From the initial euphoria over the volume, power and consumption is now not much left. It takes forever now until the laundry is dry, the dryer buzzing extremely loud and fluff go past but to a large extent on the screen, so you have to free the interior of the dryer of lint in regular intervals. For me it is clear that a "cheap" dryer will never come again in question. Rather spend a little more for it and get a decent machine with good and above all consistent performance.
