Dunkirk is one of the most established names in hydronic heating. Their reputation has been built over the years by ingenious design and perpetual innovation. The EW II is a remarkably well-rounded boiler. By blending reliability and efficiency, Dunkirk has created an oil-fired hot water boiler that is suitable for a variety of applications. Cast-iron, the material of the EW II's heat exchanger, is known for its longevity, a quality whose importance cannot be overstated when it comes to hydronic heating. To keep installation times down Dunkirk handles the installation and wiring for the EW II's Beckett AFG burner. To cap off an already impressive product, Dunkirk equips all EW II hot water boilers with high quality components—sHoneywell controls and a Taco circulator. Whether you're beginning new construction, replacing an old boiler, or considering the switch to oil, an EW II makes an excellent addition to any system.
Heat retention is a cornerstone of efficiency. Dunkirk employs an insulated boiler jacket with the EW II to reduce wasted heat and make your energy dollar go further.
The EW II will begin any demand for heat by measuring shifts in temperature within the boiler. Then, prior to firing, it will circulate any water with residual heat through your system. Reusing residual heat and limiting burner firing improves the energy efficiency of your system.
Tankless Water Heating Coil
The 4EW.90 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. To demonstrate this faith, Dunkirk has developed a 20 year, non-prorated "Cast to Last" warranty. Your peace of mind is guaranteed with an EW II.
