Aprilaire Thermostat 8400 Series Dec 14, 2016

Its difficult to believe I am the first to review this product. However this thermostat is difficult to program and seams to defy reason, when in heat mode and should be using the compressor unit outside to produce heat, it instead will be making expensive heat with AUX electric heat. I will probably dump this thing and get one I can understand how to use effectively.

Nothing But The Best Sep 12, 2016

I have 2 of the 30,000 btu units and one 75,000 btu unit. I couldn't be happier with their performance and reliability. I went with these over the competition because of the compact design and the quality that they are built with. The Reznor brand may cost more but I have dealt with other heaters that have failed and caused pipes in the garage to freeze. Now I can leave for days at a time without thinking twice about what's going on back at home in sub zero temps.

Great Product! Feb 16, 2016

Easy to install!!!

Not Great Sep 14, 2016

Not great... wish I kept my 40 year old one... it worked a hell of a lot better.

Better Than I Expected Sep 02, 2016

Installed this system in a uninsulated summer cottage. Quick to install, I had to do some carpentry work to re-support the ceiling where I cut out 2 x 2's but when I was done it really turned out better that I expected. I'll definitely buy Gree again and will recommend EComfort to all. They were the absolute best.
