Features

    Dunkirk is one of the most established names in hydronic heating. Their reputation has been built over the years by ingenious design and perpetual innovation. The WPSB hot water boiler is a prime example of these qualities. In the WPSB, Dunkirk has brought together versatility, efficiency, and reliability. Installing a WPSB is made simpler with prewired gas controls installed by Dunkirk before shipment. The boiler controls feature a clear LED temperature display and are easy to set with simple dial inputs. Cast-iron construction of the heat exchanger ensures durability and longevity, which, in turn, ensure peace of mind. Whether you are beginning new construction or making changes to an existing heating system, the WPSB overachieves. It easy to use, it provides efficient comfort, and it is built to provide these benefits year after year.

    Product Features

    Low Profile
    Many chimney vented boilers seem space conscious, but draft hoods can extend their height and make them a tight fit for boiler rooms and basements. WPSB boilers have an integral draft hood, which keeps the boiler's profile low and provides flexibility in selecting an installation location.

    Economy Mode
    The control for WPSB boilers features an energy saving operating mode. Economy Mode is set through a dial on the control. When active, it automatically manages the temperature and circulation of your system to find the perfect balance of efficiency and comfort.

    Cast to Last
    Dunkirk has the utmost faith in the quality of their cast-iron heat exchangers. To demonstrate this faith, Dunkirk has developed a 20 year, non-prorated "Cast to Last" warranty. Your peace of mind is guaranteed with a WPSB.

    Efficiency-Boosting Insulation
    Heat retention is a cornerstone of efficiency. Dunkirk employs an insulated boiler jacket with the WPSB to reduce wasted heat and make your energy dollar go further.

General Information
Product Line
WPSB
Medium Learn More
Medium
Medium refers to the substance that carries heat through the heating system. Systems are either designed to use either Hot Water or Steam as a medium, and components are usually specific to one or the other.
Hot Water
Heat Exchanger Material
Cast Iron
Fuel Type Learn More
Fuel Type
To create heat, some form of fuel is required. Fuel Type specifies what the product uses as an input to create heat.
Natural Gas
Combustion Type Learn More
Combustion Type
Condensing appliances use leftover thermal energy from combustion gases to heat water in a secondary heat exchanger, resulting in higher efficiency and lower exhaust temperature.
Conventional
Vent Type Learn More
Vent Type
Products that use combustion (burning) of fuel to create heat also create potentially dangerous gasses that need to be exhausted (AKA "Vented"). Depending on the product, venting can be done via a chimney, through a side wall, or use a second vent to provide fresh air to the appliance.
Chimney Vent
DHW Production Learn More
DHW Production
DHW (Domestic Hot Water) is potable water for uses other than space heat. Some boilers are able to provide DHW "out of the box", while others can do so with the purchase of optional accessories.

Modulating/Staging Learn More
Modulating/Staging
Stages are unique speeds or levels that equipment can operate at. More stages allow for better fine-tuned control of output, which improves comfort and efficiency. Modulating equipment can operate across a range of levels, giving the highest level of fine-tuned control. Learn More

Performance
AFUE Learn More
AFUE
AFUE (Annual Fuel Utilization Efficiency) measures the efficiency of combustion equipment over the entire heating season, and is calculated by dividing the amount of energy that is actually heating your home by the total energy contained in the fuel used by the boiler/furnace. Learn More
83.7 %
Maximum Input Capacity Learn More
Maximum Input Capacity
The Maximum Input Capacity describes how quickly the appliance will use fuel when delivering it's maximum capacity. The units may change depending on the fuel being used.
299000 BTU
DOE Heating Capacity Learn More
DOE Heating Capacity
Also referred to as Gross Output, this is the output of a boiler after accounting for combustion efficiency. We recommend sizing hot water boilers based on the DOE Heating Capacity.
251000 BTU
Net I=B=R Capacity Learn More
Net I=B=R Capacity
I=B=R, also referred to as Net Output or AHRI Capacity, is the rated heat output of a boiler after accounting for combustion efficiency, piping loss, and an extra pickup factor. We recommend sizing steam boilers based on the I=B=R rating.
218000 BTU
Ultra Low NOx Emissions Learn More
Ultra Low NOx Emissions
NOx is a byproduct of the combustion process, and it's output is regulated in some jurisdictions. Many regulators mirror SCAQMD rules, which regulate air quality for some parts of Southern California. Ultra Low NOx appliances emit less than 10-14 ng/J (nanogram per Joule) of NOx. Learn More
