Reznor Udap-300 Power Vented Gas Fired Unit Heater - Ng - 409 Stainless Steel Heat Exchanger - 300,000 Btu Review Aug 29, 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.

This is a well made product, made in the USA. Does what it is advertised to do.

Very Nice Product Sep 20, 2016

Skeptical when purchasing, very pleased with results. Packaging could be better, air relief valve was damaged (shipping company), but easily replaced with peckok valve. Will be ordering more for sure, throws off impressive heat in a slimline package. Replaced 16' of slantfin baseboard and get tons more heat. Easy to install with multiple options of h20 hookups.

Great Heater! Sep 11, 2016

This little heater does a wonderful job of keeping my two car garage nice and warm all winter long. I use my garage for a man-cave workshop in addition to parking my vehicles. I purchased this one because 15 years ago I purchased an ADP similar model. Well, after 15 well used years of 247 running, the board went out. So, instead of replacing the board I opted to replace the unit with another ADP. I don't think you can ask for many more trouble free years from any heater.
