Features

    Dunkirk is one of the most established names in heating. Their reputation has been built over the years by ingenious design and perpetual innovation. If you are looking for dependable steam heating from an oil-fired boiler, the ESC is the boiler for you. Honeywell controls and a cast-iron heat exchanger are some of the most reliable components available. Cast-iron is renowned for its heat retention and durability, two qualities that are indispensable in hydronic heating. For protection, Dunkirk designed a heat shield baffle. This baffle not only protects the ESC's casting in dangerous water situations, it also improves the unit's heat transfer qualities. With an ESC steam boiler you aren't just getting comfort, but durability and longevity as well. When it comes to peace of mind, the ESC stands out as an exceptional choice.

    Product Features

    Simplified Maintenance
    ESC boilers feature a swing open door and extra wide flueways. Proper inspection, cleaning, and servicing are all essential for efficient, safe boiler operation, and they are all made easier by these design elements.

    Tankless Water Heating Coil
    The included tankless water heating coil makes the ESC an incredibly versatile piece of equipment. Capable of producing 4.5 gallons of hot water per minute, the ESC-5185ST can provide efficient space heating and domestic hot water in a single package.

    Cast to Last
    Dunkirk has the utmost faith in the quality of their cast-iron heat exchangers, even when they are tested by the rigors of a steam heating system. To demonstrate this faith, Dunkirk has developed a 12 year, non-prorated "Cast to Last" warranty. Your peace of mind is guaranteed with an ESC.

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.

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.
Oil
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
