Whirlpool requires a professional tech to clean the machine twice a year. Miele would be a much better choice.

I have a Blomberg brand heat pump dryer, 24" inch. I think it's fantastic - it does require replacement of the additional lint filter periodically, but as long as I keep up with that it works perfectly. Dry cycle is a bit longer than a typical dryer, but not too bad. A friend also has the Miele and I think if I were choosing again I would pick that one, because it sounds like the dry cycle is a bit shorter. The energy savings are SO compelling, it can pay back any extra cost in savings in just a couple years.

We are building in a rural area so some brands are harder to get and difficult to get service. I really do not want a vent and was hoping to get a heat pump dryer but they are very uncommon here. Also I was hoping to replace both washer and dryer at the new house but had to replace my washer here which is a Speedqueen front loader. So I will probably take my washer unless the buyer wants it. i understand the heat pump dryers are smaller so wondering if my Speedqueen will work the heat pump dryer, or if it is too big. I guess I could just do smaller loads but didn’t know if that is good for my front loader. Anyway thanks for the comments everyone!

Chiming in late, but we too have a Blomberg ventless heat pump dryer and are happy with it. The regular dry cycle leaves things feeling like they're a tiny bit damp when you touch them but dry by the time they land on the counter for folding, and without the over-drying I've stopped needing fabric softener to get rid of static. I've found that if you use the crevice tool on the vacuum cleaner you can clean out the secondary filter every now and then (with a little bit of stretching it this way and that), so it doesn't need replacing very often. It's also a good reminder to vacuum the fins on the heat exchanger--and the bathroom/laundry room vent fan--at the same time.
