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.

Nice Choice Sep 06, 2016

The radiators went together very easily with the connections provided to the heating pex and there were no leaks. very easy to bleed. they provide much more heat than I was getting from my old wall convectors and seem to retain the heat a long time after the boiler is off. Not hard to hang either as long as you separate the hanger prongs in increments of 1/2 inch. Also, my wife was pleasantly surprised by the appearance

Great Unit Oct 23, 2016

Indoor Unit: Runs great. Easy to install. Almost silent at low speed and no louder than a 16" desk fan at high speed. Instructions are sparse but a DIY guy can figure them out with a little help from YouTube as well. Definitely get the outdoor cover track to make the installation look great. Easily keeps my 14x18x9 living room (east and south exposure) plus 12x12x9 kitchen plus 10x10x9 dining room cool on a 90 degree day with large window exposures on all walls. Outdoor Unit:more

Unit Woks Great But Concerned About The Lack Of Warranty Aug 01, 2016

It was easy to install and start up but in reading the manual no warranty is supplied unless the system is installed by a certified installer. The house was cold and it was Saturday so no option of contracting help. Gas furnaces are inherently reliable so probably not a problem but some warning may have changed my mind of self performing.
