Weil-McLain 88 Series
Cast-iron commercial gas hot-water boiler. 84% AFUE, Category I B-Vent, sectional design — the proven workhorse for Chicago multi-unit buildings, churches, and commercial facilities.
The Weil-McLain 88 Series is a sectional cast-iron commercial gas hot-water boiler built for Chicago's multi-unit buildings, churches, schools, and commercial facilities. Its modular cast-iron sections allow precise BTU sizing — you get exactly the capacity your building needs, not an oversized unit that short-cycles.
The 88 Series uses standard Category I / B-Vent venting, making it compatible with most existing chimney configurations in Chicago commercial buildings. This simplifies replacement installations and reduces the cost of upgrading from an older atmospheric boiler.
D's Air & Heating, Inc. installs the 88 Series 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.
