The Series DE™ boiler is a residential, gas-fired, cast iron boiler for hot water heating systems.

The direct exhaust option is ideal for applications where a chimney is inadequate or unavailable. Available with standard intermittent ignition, the Series DE™ boiler is available either natural or LP gas. Also standard on the Series DE™ boiler are Honeywell operating controls and a Taco circulator. The Series DE™ boiler is available in 4 sizes (3 - 6 sections), with inputs from 70.0 to 165.0 MBH. Cast iron sections are factory tested and assembled with steel push nipples.
