Reznor Udap-250 Power Vented Gas Fired Unit Heater, Ng, Aluminized Heat Exchanger - 250,000 Btu Review
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.
