This floor-standing unit achieves a 95.1% AFUE rating, meaning it converts nearly all of its fuel into usable heat. It accepts both natural gas and propane, giving installers flexibility depending on the job site. The boiler delivers an input of 155 MBH and a net heat rating of 143,000 BTU per hour, making it well-suited for larger residential heating loads. A stainless steel fire tube heat exchanger sits at the core of this unit, paired with a non-metallic base for corrosion resistance and long service life. The 5:1 turndown ratio allows the burner to modulate output down to roughly 20% of capacity, which reduces short cycling and improves comfort across variable load conditions. Four pump and auxiliary outputs give the installer control over multiple heating zones or system components from a single boiler. The unit supports up to eight boilers in a multiple boiler configuration with lead\/lag rotation, making it a strong choice for staged residential or light commercial systems. Modbus connectivity allows integration with building management systems for facilities that require centralized monitoring and control. Venting is compatible with PVC, CPVC, polypropylene, and stainless steel vent pipe up to 100 feet, giving contractors multiple options to match the installation. A boiler circulator is included with the unit. The Evergreen boiler features a slate gray cover, direct spark ignition, and a maximum operating pressure of 30 psi. Dimensions are approximately 42 and three quarters inches tall, 17 and five eighths inches wide, and 18 and five eighths inches deep. The system capacity is 3.2 gallons. Supply and return pipe connections are 1 and one quarter inches. The unit operates on 120\/24V single phase power. It is CEC compliant for sale in California, CSA certified, and Energy Star compliant. This boiler is a dependable choice for HVAC contractors installing high-efficiency hydronic heating systems.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e95.1% AFUE modulating condensing boiler with 5:1 turndown ratio for precise output control and reduced short cycling\u003c\/li\u003e\n\u003cli\u003eStainless steel fire tube heat exchanger with non-metallic base for long-term corrosion resistance\u003c\/li\u003e\n\u003cli\u003eSupports up to 8 boiler multiple boiler sequencing with Modbus to BMS connectivity and 4 pump\/auxiliary outputs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Weil-McLain Evergreen 672619209534 delivers 95.1% AFUE efficiency and 155 MBH input in a floor-mount condensing gas boiler built for residential hydronic heating.
