Weil-mclain 672619209527 Evergreen Hot Water Gas Boiler 110 Mbh 95% Afue Floor Wall Mount Condensing

Product Description

The Weil-McLain 672619209527 Evergreen condensing hot water gas boiler is a high-efficiency heating unit built for residential applications. It delivers 110 MBH input and 101 MBH output, achieving 95% AFUE. That means 95 cents of every dollar spent on fuel goes directly toward heating your home or building. This level of efficiency makes the Evergreen a strong choice for HVAC contractors and heating professionals looking to meet modern energy codes and Energy Star requirements.

At the heart of this boiler is a stainless steel fire tube heat exchanger mounted on a non-metallic base. Stainless steel resists corrosion and stands up to the acidic condensate produced in condensing operation. This extends service life and reduces long-term maintenance needs. The unit runs on natural gas or propane, giving installers flexibility across different job sites.

The Evergreen uses a modulating burner with a 5 to 1 turndown ratio. This means the boiler can fire as low as 20% of its full capacity, matching output to the actual heating load. That reduces short cycling, saves fuel, and improves comfort. Direct spark ignition handles reliable startup without a standing pilot.

This boiler supports up to 8 units in a multiple boiler system with lead and lag rotation built in. It includes 4 pump and auxiliary outputs, a configurable auxiliary input and output system, and Modbus connectivity for building management system integration. These features make it well suited for both simple residential installs and more complex commercial-style setups.

Venting is flexible. The unit supports PVC, CPVC, polypropylene, and stainless steel vent pipe up to 100 feet. It is rated as a direct vent boiler. Installation can be floor standing or wall mounted using the included optional wall mount kit. The boiler circulator is included, reducing the number of additional parts needed on the job.

The unit measures 17 inches wide, 18 and 5 eighths inches deep, and 42 and 3 quarters inches tall. Water capacity is 2.5 gallons. Maximum working pressure is 30 psi. Supply and return pipe connections are 1 inch. Operating voltage is 120 and 24 volts single phase. The slate gray boiler cover, introduced in 2021, gives the unit a clean, professional appearance. CEC compliant for sale in California. CSA certified. Energy Star compliant.
