Ensure consistent and efficient heating with this boiler!
The Dunkirk WPSB-3D Series II WPS307503210203 boiler is an efficient and reliable choice for home heating, offering an 84.0% AFUE rating for optimal fuel usage. With a size of 75 MBH, this gas-fired hot water 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 6.3 gallons of water content contribute to efficient heating performance. This model includes a Taco Pump.
