Weil-McLain ECO Tec® Boiler Installation Chicago
Weil-McLain · Chicago Installation
ECO Tec® Series
Standard hot-water and combi boiler options — up to 95% AFUE for Chicago homes.
Why D's Air & Heating, Inc. Recommends ECO Tec® Series
Series 2 & Combi Options
The ECO Tec lineup includes a standard hot-water boiler (Series 2) and a combi boiler (Series 3) for space heating and domestic hot water in one unit.
Up to 95% AFUE
The ECO Tec Series 3 Combi reaches 95% AFUE — top-tier efficiency for combined heating and hot water.
Direct Vent / PVC
Sealed combustion with PVC venting for safe, flexible installation in Chicago homes.
Stainless Heat Exchanger
Built for condensing operation with long-term durability.
Combi Option Available
The Series 3 Combi provides both space heating and on-demand domestic hot water — no separate water heater needed.
Weil-McLain Warranty
Backed by Weil-McLain's limited warranty. D's Air & Heating, Inc. registers at startup.
The Weil-McLain ECO Tec® lineup offers two residential options: the Series 2 standard hot-water boiler and the Series 3 Combi. The Series 2 is a reliable 84% AFUE atmospheric boiler for straightforward hot-water heating replacements. The Series 3 Combi steps up to 95% AFUE and adds on-demand domestic hot water — eliminating the need for a separate water heater.
The ECO Tec Series 3 Combi is particularly popular in Chicago two-flats and greystones where mechanical room space is limited. Combining space heating and domestic hot water in a single wall-hung unit simplifies the mechanical room and reduces installation cost.
D's Air & Heating, Inc. installs both ECO Tec models throughout Chicago and the southwest suburbs. We handle all City of Chicago mechanical permits, piping, controls, and startup — and register your Weil-McLain warranty before we leave.
