About the Dunkirk WPS929913200203

Ensure consistent and efficient heating with this boiler!


The Dunkirk WPS929913200203 gas fired hot water boiler from the WPSB-9D Series II is an efficient and reliable choice for home heating, offering an 83.7% AFUE rating for optimal fuel usage. With a size of 280 MBH in and 235 MBH out, this boiler ensures dependable performance with its cast iron heat exchanger and cast iron push nipples. The materials expand at the same rate when heated, allowing the boiler to maintain a tight seal over time without the need for cheaper gaskets, ensuring durability and long-lasting operation.


Equipped with the Advanced Fuel Smart Hydrostat Control, this boiler offers three essential functions in one control: a temperature limit, a low water cut-off (LWCO) to protect from low water conditions, and a boiler reset that optimizes fuel savings by adjusting the temperature and activating the burner only when necessary. The setup is straightforward, requiring no outdoor sensor—just dial in the number of heating zones for efficient operation.


This boiler is designed with an atmospheric chimney vent and comes with an integral draft hood and vent damper. These features make it ideal for installations with low clearance, as the integral draft hood reduces the overall height and footprint, providing flexibility in tight spaces. The 1-1/4" return/supply water connections and 1/2" NPT gas inlet ensure ease of installation, while the 17.2 gallons of water content contribute to efficient heating performance. This model doesn't include a pump.


With a sleek, textured paint jacket for added durability, this Dunkirk WPSB-9D Series II WPS929913200203 is backed by the Cast to Last Warranty, offering a 20-year non-prorated limited warranty to ensure long-term peace of mind. Whether for residential or light commercial applications, this boiler offers the efficiency, reliability, and features you need for year-round comfort.
