Reznor Udap-400 Power Vented Gas Fired Unit Heater, Ng, Aluminized Heat Exchanger - 400,000 Btu Review Aug 04, 2016

I have owned this same 400k btu unit for 8 years and it is the best purchase that I have ever made. It is used in a commercial setting and has never had a problem or service call. Reznor quality is second to none and definitely worth the extra cost.

Easy Install Apr 15, 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.

Saved A Lot Of Money Sep 21, 2016

AC unit of 8 years died during heat spell and contractors where quoting very high prices to replace. Having some mechanical ability I decided to purchase and install a new unit myself. eComfort guided me through the whole system and the new unit was shipped to Calif. in just a few days. Had new unit installed in two days and had a licensed AC Tech do my start-up. I saved almost $6000 dollars. New project will be a whole house fan system which they also sell.
