Weil-McLain Evergreen® Commercial
High-efficiency condensing commercial gas boiler. 95% AFUE, direct vent PVC, 300K–600K BTU/hr — premium efficiency for Chicago's commercial and multi-unit buildings.
The Weil-McLain Evergreen® Commercial is a high-efficiency condensing gas hot-water boiler delivering 95% AFUE in a commercial package. Its modulating burner adjusts firing rate to match actual building heat demand — eliminating the energy waste and temperature swings caused by on/off cycling in standard atmospheric boilers.
Available in four models from 300,000 to 600,000 BTU/hr, the Evergreen Commercial is well-suited for mid-size commercial buildings, large multi-unit residential buildings, and institutional facilities where energy efficiency and long-term operating cost matter.
D's Air & Heating, Inc. installs the Evergreen Commercial throughout Chicago and the southwest suburbs. We handle all City of Chicago commercial mechanical permits, system piping, controls, and startup — and register your Weil-McLain warranty before we leave the job.
