I was looking for an alternative to an "in ceiling" combo fan/heater that makes quite a bit of noise. My choices were limited due to floor to ceiling tile work not allowing anything in the wall. I'm not sure how it came up, but the Envi looked like a fix for my issues. I installed the same day I received it and after some modifications to the tile(I bought the hardwired version 500W 120V) it's up and runnng and doing a good job of keeping it habitable(the ceiling is in mid remodel while the bathroom above is also in remodel) so far. I'm sure once the ceiling is insulated and buttoned up it will be very pleasant.
