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.

One of the 9 units I bought went bad in… One of the 9 units I bought went bad in 2 weeks . Almost impossible to replace . Terrible customer service

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.

Still Waiting For My Heater I ordered an Envi Heater two weeks ago as I thought it would be perfect to help warm up my living room. Both the website and the email I received from them stated that it would be shipped in 5-7 business days. When I check on my order status, it still says "awaiting fulfillment" and I still haven't received my order. Hopefully it will be shipped soon or I will be canceling my order and getting a refund.

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 .
