Reznor Udap-400 Power Vented Gas Fired Unit Heater - Ng - 316 Stainless Steel Heat Exchanger - 400,000 Btu Review Aug 12, 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.

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.

I just want to say I bought these two units from eComfort they made it so easy to purchase, fast shipping and they work great thank you. I would recommend them to anybody and I will purchase from these people again.
