Innovative. Efficient. Dependable. Dunkirk.
Since 1928, Dunkirk has delivered innovative, efficient and dependable home heating products to professionals, building owners and homeowners. We take pride in our products. We listen to the people in the field who do the tough work, and we design around their feedback and suggestions. 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 residential- and commercial, hot-water boilers, steam boilers, indirect water heaters, and all HVAC products.
For example, the 95%-AFUE Dunkirk Helix VLT Gas-Fired, Modulating Condensing boiler. At the suggestion of many heating professionals from across the country, we designed a new type of heat exchanger . This vertically mounted, helical fin-tube heat exchanger has wide, smooth waterways, designed with hard-water deposits and scale in mind. We fabricated this new heat exchanger from 316L/444 stainless steel for long life, and we back it with an outstanding warranty. We believe in this boiler, inspired by real-world, professional feedback.
Dunkirk products offer:
- Original, innovative designs that are the result of American Ingenuity
- Solid reliability
- Quality components
- Outstanding warranties
- Service professionals who listen, and react quickly
