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.
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 ESC-4125S has an opening for adding a tankless water heating coil. This allows you to combine domestic hot water production and space heating in a single, efficient 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.
