Reznor Udap-300 Power Vented Gas Fired Unit Heater - Ng - 316 Stainless Steel Heat Exchanger - 300,000 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.

Too Early To Tell Jul 23, 2016

Hooked up the heater in late June, so no way to tell how it will work when the cold weather arrives.

One the top was banded a "cone" which prevented the unit from stacking. It was delivered by R & L delivery truck with a lift gate, and it was received without a dent or mark of... more

Aprilaire Thermostat 8400 Series Dec 14, 2016

Its difficult to believe I am the first to review this product. However this thermostat is difficult to program and seams to defy reason, when in heat mode and should be using the compressor unit outside to produce heat, it instead will be making expensive heat with AUX electric heat. I will probably dump this thing and get one I can understand how to use effectively.
