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. By blending reliability and efficiency, Dunkirk has created an oil-fired combi boiler that is suitable for a variety of applications. The 4EW1.50 features a tankless coil to handle production of domestic hot water. It is part of Dunkirk's EW II line of remarkably well-rounded boilers. By combining space heating and water heating in a single package, the 4EW1.50 is making the most out of your energy. 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 included tankless water heating coil makes the EW II an incredibly versatile piece of equipment. Capable of producing 3.75 gallons of hot water per minute, the 4EW1.50 can provide efficient space heating and domestic hot water in a single 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.
