Weil-mclain 383900177 Eco Tec 110-H 110 Mbtu 95% Afue Natural Gas Condensing Hot Water Boiler Series 2 Direct Vent

Product Description

The Weil-McLain 672619221277 ECO Tec 110-H is a natural gas condensing hot water boiler designed for residential hydronic heating systems. It delivers 110,000 BTU input and achieves a 95% AFUE rating, meaning the vast majority of fuel consumed is converted directly into usable heat. This makes it one of the more efficient options available for homes transitioning away from older, lower-efficiency boilers. HVAC contractors and plumbers will appreciate the straightforward installation process and the thoughtfully organized cabinet layout that keeps all critical components accessible during service calls. The unit is built around a stainless steel firetube heat exchanger with a vertical orientation that promotes self-rinsing during operation, reducing buildup and extending service life. The ECO Tec Series 2 features the Unity 2.0 multi-zone controller with a large touchscreen display and a Setup Wizard that walks installers through configuration. The controller comes preloaded with 10 system-type options, allowing technicians to assign different zone temperatures and priorities without additional programming hardware. A built-in ECM circulator pump is included, which saves both installation time and electrical energy compared to standard wet-rotor circulators. The sealed cabinet design preheats incoming combustion air before it reaches the blower and burner, supporting cleaner ignition and protecting internal components from debris. A sound-dampening air silencer keeps operation quiet during normal heating cycles. Direct vent configuration allows the unit to draw combustion air from outside, making it suitable for tightly sealed modern construction. The boiler has a tank capacity of 2.2 gallons and accepts a 3-inch vent connection. Overall dimensions are 33 inches tall, 19 inches long, and 20 inches wide, fitting standard mechanical room footprints.
