Great Unit, Love It Dec 12, 2016

Installed it in a 16ft x 20ft building. Works extremely well. Keeps the building at 50 degrees when unoccupied, then heats it up to 70 degrees fast when occupied.

Easy to install, though had to use local HVAC company to maintain warranty. Works great. Quiet. Just tried heat and it is a happy addition. We have owned this unit for about 6 months and are located in the Florida Panhandle.

Replaced a 22 year old Triangle tube heater with the Smart 40. My furnace hardly ever runs to keep my hot water hot unless I am using it. Really holds the heat. I have had it installed about a month now and I think it was a great purchase. A little expensive, but if it last as long as my last one, I'll be happy.

Very quiet, you can only hear the fan running. Suction line service valve is too close to the case makes it difficult to braze the suction line in.

Easy Install May 30, 2016

Using in warehouse to prevent pipes from freezing, but since the weather hasn't been very cold it is difficult to evaluate. The install was fairly easy.
