Product Description
The Weil-McLain 672619203532 Evergreen Hot Water Gas Boiler is a high-efficiency condensing boiler built for residential heating applications. It delivers 220 MBH input and 206 MBH output with a 95% AFUE rating, making it one of the most fuel-efficient gas boilers available for home and light commercial heating systems. The unit runs on natural gas or propane and uses direct spark ignition for reliable startup every cycle.
At the core of this boiler is a stainless steel fire tube heat exchanger mounted on a non-metallic base. Stainless steel construction resists corrosion from condensate, which is a common concern in high-efficiency condensing boilers. The heat exchanger is built to handle the thermal stress of repeated heating cycles over years of continuous operation.
This Evergreen boiler features a 5:1 modulating turndown ratio, which means the burner adjusts its output to match the actual heat demand of the building. This reduces short cycling, saves fuel, and extends the life of the unit. The boiler supports up to 8 units in a multiple boiler control setup with lead and lag rotation, making it well-suited for larger residential systems or staged heating zones.
Installation is flexible. The unit is floor standing but supports an optional wall mount kit. Venting is compatible with PVC, CPVC, polypropylene, and stainless steel vent pipe up to 100 feet. The direct vent configuration pulls combustion air from outside, improving safety and efficiency. Four pump and auxiliary outputs give installers control over zone pumps, domestic hot water priority, and system accessories. Modbus connectivity allows integration with building management systems. The boiler circulator is included. Supply and return pipe connections are 1.5 inches. Maximum working pressure is 30 psi. Operating voltage is 120/24V single phase. The unit measures 45 inches tall, 24 inches in length, and 22.75 inches wide and deep. Water capacity is 4.6 gallons. ANSI Z223.1 and CSA certified. Energy Star compliant and available for sale in California.
