Great System! Sep 15, 2016

I purchased this unit as a replacement for an older unit of another brand. The difference is stunning. It is SUPER quiet and yet extremely efficient. I would highly recommend this system.

It was an easy installation and it went in with no problems. Didn't have to do any adjustments all the factory setting were good and it went right in and hook up was seamless. I would buy another!

Quality Nov 10, 2016

Have used Runtal UF series before and the quality is excellent. Now if they could sneak more BTUs per foot.

Nothing But The Best Jun 10, 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.
