Series EC/ECT™

Products » Residential Boilers » Series EC/ECT™

The Series EC/ECT™ is a residential, oil-fired boiler for steam or hot water systems. Available as a packaged or knockdown unit, the Series EC/ECT™ is for use with natural draft (chimney) venting. The large water content of the boiler makes it ideal for steam and large volume hot water applications. Features include steel push nipples that provide a permanent water tight seal between sections, and a deluxe, insulated enameled steel jacket that reduces boiler heat loss. A full plate swing-out door on the Series EC/ECT™ allows for quick and easy boiler cleaning. Honeywell operating controls, a Taco circulator, and a float type low water cut-off on packaged steam boilers are all standard equipment on Series EC/ECT™ boilers.

High Efficiency, Flame Retention Burners

Peerless® Series EC/ECT™ boilers are available with your choice of Beckett, Carlin or Riello burners. These burners feature a high voltage, solid state igniter that improves ignition, and a state of the art motor that results in a lower amp draw and cooler operation. Burners also include a solid state control with interrupted ignition, limited recycle and reset, a pre-purge and other features that assure dependable service. The combination of the advanced control and a solenoid oil valve results in cleaner and quieter burner operation.
