    ***Scratch & Dent*** Dents on right side panel. 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 Excelsior EXB is a highly efficient oil-fired boiler produced by Dunkirk. It excels in new construction or as a replacement boiler. This is due in large part to the EXB's fantastic versatility and longevity. Excelsior EXB boilers are designed with ease of installation and ease of use in mind. The boiler's compact design makes it easy to fit into your home's system and a reversible burner door provides even more flexibility. The EXB features straightforward dial-based controls with a clear LED screen. Setting your boiler for comfortable, efficient operation is rarely easier than it is with an EXB. Dunkirk selected cast-iron for the Excelsior EXB's heat exchanger because of the material's reliability and durability. When it comes to oil-fired hydronic heating, the Excelsior EXB is one the best options available.

    Product Features

    Three Pass Heat Exchanger
    For the EXB's cast-iron heat exchanger Dunkirk employed a three-pass design. This design maximizes heat transfer by routing the boiler water through the heat exchanger three times. Superior heat transfer means less wasted energy and more efficient heat.

    Economy Mode
    The control for Excelsior EXB 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.

    Simplified Maintenance
    The reversible burner door of the Excelsior EXB provides quick access to the heat exchanger and oil line for inspection and service purposes. Extra wide flueways also streamline the maintenance process; they accumulate less dirt and are easier to clean.

Excelsior EXB
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
Fuel Type To create heat, some form of fuel is required. Fuel Type specifies what the product uses as an input to create heat.
Oil
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

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.
176000 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.
153000 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
