Nothing But The Best Oct 17, 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.

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.

Nice Compact And Quiet Unit Works Well. Nov 07, 2016

Some details about the unit not in the description - comes with about 10' power cord/plug for the motor, 1" fittings are standard copper pipe sweat fittings, top and bottom frame just fits finished 2x4. Makes it easy to make a quick wood mounting frame. Unit radiates about 45K BTU with 167 degree water circulated into it at 2.1 gpm (return temp is 124 degrees). Fan is fairly low noise. Louvers a little light weight, have unit on the floor with louvers taped open.
