Dunkirk Plymouth Ultra Gas-Fired Hot Water Boiler Electronic Ignition, Taco Pump 84% AFUE - 225,000 BTU - WPSB-7D

The Plymouth 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 utilizes built-in draft diverter technology that is factory designed to protect against carbon monoxide back drafts. Unlike competitor’s diverters erected in-field, Dunkirk eliminates any installation guesswork to ensure your family's safety.

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 Plymouth Water Boiler fits in tight spaces and is supplied assembled, with controls that are accessible and completely wired. Piping is also at hand for easy connection to the system. Controls can be mounted on the right or left side of our boilers, to fit any location requirement.
