Weil-McLain products at The House Supplier include the Evg 155 boiler, a 155 MBH gas unit listed with a Taco 007e / VR1816 circulator configuration. It is intended for residential and light commercial hydronic heating systems.
Before choosing a boiler, run a heat-loss calculation so the input matches the building load rather than the old unit. Confirm gas type and supply pipe size, the venting method and approved vent materials, and the near-boiler piping the installation manual requires. Check the circulator selection against the system head and flow, and plan for a low water cut-off where code requires one.
