Oil boilers are commonly used in areas of the country with limited access to other heating fuel options such as natural gas. At N.H. Yates, we are proud to be a manufacturer’s representative for Dunkirk and their complete line of oil boilers. All Dunkirk Oil boilers come with the most straightforward, comprehensive warranty in the industry. This warranty includes a limited lifetime on the entire heat exchanger and not just the individual sections. Here is more information on two of the most popular models of Dunkirk Oil Boilers.
Excelsior EXB Series Dunkirk Oil Boilers
The Dunkirk Excelsior EXB High-Energy 3-Pass oil boiler features a high limit control panel with LED display and easy to program dial settings. In addition, this unit features a more compact design than the previous model Excelsior which makes it more eco-friendly (AFUEs as high as 87%) and easier to install. The EXB is also easy to maintain with wide flute ways, flexible oil lies, dual hinged swing doors, and a site glass test port. For safety, this unit comes with a boil water temperature reset and low water cut off functionality.
EW Empire II Series II Dunkirk Oil Boilers
The Dunkirk EW II Series II is available in eight sizes, from 91 to 245 Mbh and offers up to an 86.5% AFUE. This unit features a dependable cast iron heat exchanger with cast iron push nibble and a Honeywell High Limit and Circulator Relay Control with digital temperature display and diagnostics. In addition, the EW II Series II comes with an atmospheric chimney vent boiler with a textured paint coating and a 20 year “Cast to Last” Warranty on residential applications. With the Less Coil model, the control monitors water temperature and delays the burner from starting until any residual heat has been transferred. However, with the Coil version, the low limit control seeks maximum temperature to satisfy domestic hot water call bypassing thermal purge logic.
