Dunkirk 3EW.65 EW II Atmospheric Boiler from the Empire Water series (91 Input MBH, 80 Heating Capacity MBH, 70 AHRI Net MBH, EWB306531100203) at PlumbersStock. This hot water boiler is oil-fueled, includes a Beckett Burner, and has an AFUE rating of 0.863.
Return water supply is 1-1/4-inch NPT. It operates on 120 volts AC, 60 hertz, 1 phase at less than 12 amps. This model includes a chimney-vented configuration (8″ x 8″ x 15′) and has no pump and no coil. This is a high-efficiency model. The High Limit Control is user-friendly and has a digital display. No coil means control monitors water temperature and delays the burner starting until any residual heat has been transferred. Thermal purge logic measures rate of temperature change inside the boiler and delays burner firing accordingly. This maximizes efficiency by turning on the burner only when needed.
