Dunkirk XEB Series Gas-Fired Hot Water Boiler Electronic Ignition, Taco Pump 84.4% - 42,000 BTU, XEB-2

The XEB Water Boiler by Dunkirk offers the best combination of heating comfort, efficiency, reliability and affordability, making it one of America’s Hottest Boiler Values.

Dunkirk’s exclusive high-tech titanium composite burners resist corrosion and oxidation while withstanding more heat than conventional stainless steel or aluminized burners. They provide superior strength and longevity and are backed by a full 3-year warranty, triple the industry standard.

Dunkirk utilizes cast iron to construct the boiler’s heat exchanger to provide heat transfer, reliability and strength. Since like materials expand and contract in the same proportion during heating and cooling, cast iron push nipples and sections produce stronger, more water-tight seals than steel push nipples or rubber gaskets.

Surprisingly compact, the XEB Water Boiler fits in tight spaces and is supplied assembled, with controls that are accessible and completely wired. Venting through chimney is standard, or the XEB may be side-wall vented with stainless steel vent pipe.
