    ***Scratch & Dent***Scratches and Dents on exterior panels including back, top, and side panels. Dunkirk is one of the most established names in heating. Their reputation has been built over the years by ingenious design and perpetual innovation. The PSB is Dunkirk's premier gas-fired steam boiler. Built for efficiency and durability, the PSB is a versatile steam heating solution that fits a variety of applications. The PSB features supply and return tappings on both sides of the boiler, which gives you the flexibility to install it in any location. Using both supply tappings is also an option, this can help to provide the driest steam possible for heating your home. To save time during installation and prevent installer error, Dunkirk prewires and installs the gas control system during production. The longevity and stability of a cast-iron heat exchanger means that you'll be enjoying even heat from the PSB for years into the future. Whether you are replacing your existing boiler or have a new installation, the PSB will provide reliable, efficient comfort.
  • Low Profile
  • PSB boilers have an integral draft hood, which keeps the boiler's profile low and provides flexibility in selecting an installation location.
  • Cast to Last
  • Dunkirk has developed a 12 year, non-prorated "Cast to Last" warranty. Your peace of mind is guaranteed with a PSB.
  • Efficiency-Boosting Insulation
  • Heat retention is a cornerstone of efficiency. Dunkirk employs an insulated boiler jacket with the PSB to reduce wasted heat and make your energy dollar go further.
  • Product Includes
  • (1) Dunkirk PSB-8D Steam Boiler
  • (1) Vent Damper
Specifications
General Information
Product Line
PSB
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.
Steam
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
Conventional
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 ? 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.
No
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

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.
262500 BTU
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.
214000 BTU
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.
161000 BTU
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
82 %
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
