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.

Just purchased our second Envi heater Just purchased our second Envi heater. The far bedrooms in our 2-story, single HVAC zoned-home get very cool in the winter. Even at a very low setting, the Envi is easily able to keep the chill out of the room, which allows us to keep the heating system at a lower setting overall. The second unit will replace a conventional oil-filled radiator that we currently use in the Master Bedroom. The Envi is easy to install (plug-in version), makes no noise, is energy efficient, and works really well! The build quality is excellent. This product is highly recommended!

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

These heaters are excellent. These heaters are excellent in bedrooms at the end of your forced air heating runs that are tough to keep warm. They do an incredible job of keeping rooms around 150 to 175 square feet very comfortable. Installation is simple and the results are nearly immediate.

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!
