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.

Well Made Heater Oct 18, 2016

This heater was easy to install, it is made of high quality metal. Nice to have power connections on both sides of the heater and ample amount of heat.

Arrived Complete & As Described Sep 12, 2016

Arrived promptly. Manufacturer readily available w/ live human beings answering the phone to provide tech/installation assistance. Straight forward installation w/ instructions, but would have liked a bit more detail on circulator placement. Installed & fired up in midst of cold snap. Only been a couple of weeks, but working without a hitch so far and heating house beautifully.

Easily keeps my 14x18x9 living room (east and south exposure) plus 12x12x9 kitchen plus 10x10x9 dining room cool on a 90 degree day with large window exposures on all walls. Outdoor Unit:more
