Dunkirk DCB

Since 1928, Dunkirk has delivered innovative, efficient, and dependable home heating products to professionals, building owners, and homeowners. We take pride in our products and listen to the people in the field who are doing the hard work. We design our products around their feedback and suggestions and have found that this is the best way to deliver heating equipment that lasts and reduces home heating costs. We believe in the strength of American Ingenuity when it comes to our residential and commercial, hot-water boilers, steam boilers, indirect water heaters, and all HVAC products.

We designed a new type of heat exchanger: the 95%-AFUE Dunkirk Helix VLT Gas-Fired, Modulating Condensing Boiler. It is a vertically mounted, helical fin-tube heat exchanger with wide, smooth waterways, designed with hard-water deposits and scale in mind. This new heat exchanger was inspired by real-world professional feedback! It is fabricated from 316L/444 stainless steel for longevity and backed with an outstanding warranty for peace of mind.
