Weil-McLain Combi Boilers in Greater Vancouver
140+ years of American boiler manufacturing with advanced ECI controls
Weil-McLain brings 140+ years of American boiler manufacturing into modern condensing units, with advanced ECI controls and BACnet compatibility for complex and commercial systems.
Weil-McLain's modern condensing boilers feature the advanced ECI (Energy Control Interface) controller, which provides real-time diagnostics, cascade management, and BACnet compatibility for integration with building automation systems. This makes Weil-McLain equally strong in residential applications and complex commercial installations where the boiler needs to communicate with a building's central control system. The proven cast-iron heritage has evolved into modern stainless-steel condensing technology without losing the reliability that built the brand's reputation.
Our licensed gas fitters install, replace, repair, and service Weil-McLain Evergreen and Ultra boilers across Greater Vancouver. For homeowners who value heritage, proven reliability, and advanced controls in a single package, Weil-McLain is an excellent choice.

This is not a DIY repair
Combi boilers are gas-fired appliances regulated under the BC Safety Standards Act. Opening the unit, touching the gas valve, or working on the flue without a valid BC gas-fitter licence is both unsafe and illegal. Diagnosing the fault is helpful — fixing it should always be left to a certified technician.
