Reznor Udap-400 Power Vented Gas Fired Unit Heater - Ng - 409 Stainless Steel Heat Exchanger - 400,000 Btu Review Sep 03, 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 Sep 02, 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.

The Right Decision Aug 19, 2016

Replaced a 26-year-old attic fan with the CL-6400. It was the right move. Very quiet, and it moves a lot of air. Cools the house down nicely.

Great Product And Great Customer Service May 18, 2016

Ecomfort had the best price and their customer service is great. They helped with all my install questions and what parts go with what. And best tee yet, the installation was simple. Thanks eComfort. I'll be back next time!

Nothing But The Best Sep 09, 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.
