Best heater ever Best heater ever. Everything they say about them is true; very efficient, silent, low profile and totally dependable. We have purchased 3 and our neighbor has 8 ( her house is two story, 23 feet tall and wide open. She, too, is completely satisfied.

Lousy and Unfair Customer Returns Process! Lousy customer returns process. The on/off button on our newly purchased Envi heater remained depressed and permanently stuck in the ON position. I contacted eHeat using their web form to no avail, so I finally called. The rep wanted me to return the heater before they would send a replacement. When I protested that this would mean our room woutd be heat-less until we rec'd a replacement heater - because of a FLAW IN THE PRODUCT, he offered to ship the replacement after we showed proof of mailing the malfunctioning product. That still means days of being heat-less (in the TV room where we installed the Envi) until we receive the replacement. That seems really UNFAIR for something that isn't our fault but the result of a MALFUNCTION IN THE ENVI PRODUCT.

12 out of 41 heaters in our… 12 out of 41 heaters in our five-year-old building have Failed - not a very good reliability percentage! Because these wall mounted units are hardwired we can’t just plug them in. we have had to hire a Electrician every time we’ve had to replace one. Cost as much is the heater itself!

The heaters are easy to install, perform well The heaters are easy to install and work great! They heat up a medium sized bedroom - boosting a single, challenged, old fashioned forced air heating duct upstairs in my 1909 house. I've installed a plug-in unit in all three bedrooms and everyone loves them. They are not hot to the touch on the front panels. For reference, where I live it gets down to freezing outside but usually is in the 40s F. As you can guess, this old house has limited insulation. I didn't give 5 stars because pre-sales tech support was not very knowledgable at the time I ordered my first units, last year. However, all questions were answered by good instructions included with heater.

Worried Issues; Customer Service Web site stated 1 to 2 business days to ship (but need to take holidays into account) Although ordered around holidays, order status was awaiting fulfillment. When I called customer service, another 12 days before fulfilment. Obviously, Haven't had a chance to review unit, but will if it arrives .
