Compact, Cast‑Iron Durability
A rugged cast‑iron heat exchanger with dry‑leg end sections is pressure‑tested at the factory for long service life—ideal for traditional baseboard and radiator systems.
Fuel‑Saving Ignition & Vent Damper
The boiler’s electronic ignition fires only on a call for heat, and the motorized vent damper helps reduce standby losses compared with older standing‑pilot designs.
Flexible Left/Right Piping & Wiring
Water, gas, and electrical connections can be routed from either side of the cabinet, making replacements cleaner in tight mechanical rooms.
Low‑Profile Draft Diverter
The integrated draft diverter lowers overall height, so the 15B‑150K fits low‑ceiling basements where external draft hoods are a challenge.
Zoning‑Ready Hydronic Heating
Pair with zone valves or circulators (not included) to serve multiple heating zones. The 1‑1/4" tappings support common residential manifolds and near‑boiler piping layouts.
