Reznor Udap-350 Power Vented Gas Fired Unit Heater - Ng - 409 Stainless Steel Heat Exchanger - 350,000 Btu Review Sep 24, 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.

Lots Of Heat Oct 17, 2016

I have a 25' x 40' insulated garage. My new 60K btu Reznor heater brings the temp. from 50 degrees to 65 degrees in about 25 min. I love it.

Warm And Cozy Sep 17, 2016

I bought this unit not knowing if it would heat my 19 x 21 kitchen, but to my surprise I have not had to turn the unit any higher than 4 and that was on a -20 day . So my wife is well pleased with me.

I replaced a Dunkirk XEB-3 (20 yrs. old) with the Dunkirk boiler above. The new one is all most identical to the old one, that is the pipes were located same as the old, so gas and water lines were easily plumbed. The old electrical wires could be used although lengthened to connect to the digital controls. The circulators location has changed, it's still provided with its wiring provided. Venting is the same as the old one. I was happy to get another Dunkirk that installed easily.
