Owner, Custom Made Aug 12, 2016

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.

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.

Nice Compact And Quiet Unit Works Well. Oct 06, 2016

Some details about the unit not in the description - comes with about 10' power cord/plug for the motor, 1" fittings are standard copper pipe sweat fittings, top and bottom frame just fits finished 2x4. Makes it easy to make a quick wood mounting frame. Unit radiates about 45K BTU with 167 degree water circulated into it at 2.1 gpm (return temp is 124 degrees). Fan is fairly low noise. Louvers a little light weight, have unit on the floor with louvers taped open.
