This baby kept my sweltering Pacific NW cottage comfy in the peak days of summer. Now that it's cooling, I'm starting to use it for heat. But it shuts off in LESS THAN 2 HOURS b/c it needs to be drained. The auto-drain feature doesn't work in heat mode. And there are no instructions on how to rig up a permanent drain line - I'm not even sure it's a possibility without a pump. The until only needed to drain 1x in the whole summer though.

The model is marketed as multi-functional but it's only usable as a heater and dehumidifier in the narrowest of circumstances without facing drain issues -- and that's what upsets me. I did hours of research and bought what I thought was the best product out there, and it's only the best product if you live in a specific climate (dry) and are using a portion of its features -- and you wouldn't need a dehumidifier if that was your climate. 

Do better Whynter.
