Residential Boilers - Oil Boilers Series EC™ with Optional Tankless Heater Boiler

The Series EC™ is a residential, oil-fired, cast iron boiler for steam or hot water systems. The large water content of the boiler makes it ideal for steam and large volume hot water applications. The EC boiler has an AFUE of up to 87.6% – ENERGY STAR® certified – and features high efficiency, flame retention burners in choice of Beckett, Carlin or Riello. Optional tankless coils can be added for all your domestic hot water needs. A full, non-prorated lifetime warranty is included for all water boilers and a limited 10-year warranty covers the heat exchanger of steam boilers.

*As an ENERGY STAR® partner, PB Heat, LLC has determined that these firing rates meet the ENERGY STAR® guidelines for energy efficiency.
† All chimneys are 8″ x 8″ x 20′ except those models denoted with †, which are 8″ x 12″ x 20′.

1 Burner input based on No. 2 fuel oil with a heating value of 140,000 Btu per gallon.
2 Net water ratings based on an allowance of 1.15, net steam ratings based on an allowance of 1.333. Consult factory before selecting a boiler for installations having unusual piping and pickup requirements, such as intermittent system operation, extensive piping systems, etc.
3 Output is Heating Capacity for models with inputs <300 MBH and Gross Output for models with inputs ≥300 MBH. Heating Capacity and Annual Fuel Utilization Efficiency (AFUE) ratings are based on U.S. Government tests.
4 Thermal efficiency and gross output are determined in accordance with ANSI/AHRI Standard 1500.
