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.

Excellent experience... ordered on a Thursday... at my location by Tuesday......I would call first to make sure one has all the parts/items needed to make sure everything you need is correct .....Would definitely recommend & buy from again!

Had this boiler for 2 winters now in MA. First winter was hard. This last one less so. Great product. Made is USA. Cast iron. Will last forever my plumber tells me. Still 84% efficient. Doesn't need yearly maintenance like the higher efficient junk out there. That high efficient junk also requires a power vent that is super loud. Consider that too in your purchase. This Burnham is very quiet. No power vent. I use an old school dial thermostat and set it at 67. When I get my heating bill... more

Nothing But The Best Oct 19, 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.
