Great Warehouse Unit. Feb 24, 2016

Easy to install and works nicely. A little noisier than expected, But I guess that is expected with a big fan.

Great Unit, Love It Jun 09, 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.

Good Unit Sep 14, 2016

Replaced out a Rheem 90% with this unit. Easy installation. Very quite running. Seems to run less than the old unit. Highly recommend.

New Heater Installed Nov 03, 2016

The heater was ordered on a Friday and I could have gotten it on Wed but I could not have anybody here to receive it till Friday. It arrived on Friday morning just as I finished taking out the old furnace. I had it up and running by Monday, I tried to get the new one as close as possible as the old one in output and so I only got the single stage. I could not find the size as to how wide, deep, or height but that was probably my fault but it worked out great the only difference was the height... more

Money Saver Dec 20, 2016

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.
