Built with a stainless steel fire tube heat exchanger, this gas-fired boiler achieves a 95% AFUE rating, delivering strong fuel efficiency that reduces operating costs for homeowners and keeps HVAC contractors compliant with energy standards. The Eco Tec series combines space heating and domestic hot water into one compact wall-mount or floor-mount appliance, making it a practical choice for homes with limited mechanical room space. It connects directly to natural gas supply and operates on standard 120V single-phase power with electronic ignition for reliable, repeatable startup. The updated Unity 2.0 color touch screen features text-based menus and a setup wizard, so technicians can configure the system quickly without consulting external documentation. Multi-boiler functionality is available through an optional wiring kit, giving installers the flexibility to stage multiple units in larger residential applications. The boiler supports up to 10:1 turndown ratio, meaning the unit self-adjusts its firing rate to match the actual load, minimizing short cycling and reducing fuel consumption during mild weather. Domestic hot water output reaches up to 5.4 GPM at a 70-degree temperature rise, meeting the needs of most residential households. The unit operates up to two zone circulators and one boiler circulator, supporting zoned heating layouts common in retrofit and new construction projects. Venting is flexible, accepting PVC, CPVC, polypropylene, or stainless steel pipe. Runs up to 100 feet with 3-inch pipe or up to 50 feet with 2-inch pipe in a direct vent configuration. The insulated heat exchanger and domestic hot water pipes reduce standby heat loss and limit operating noise. An outdoor temperature sensor is included to enable outdoor reset control for improved efficiency. The unit is NSF 372 certified, ANSI 372 compliant, Energy Star certified, UL Listed, and approved for sale in California under CEC requirements. Supply and return pipe connections are 1 inch. Unit dimensions are 33 inches tall, 20 inches wide, and 19 inches in length. Internal capacity is 3.8 gallons.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e95% AFUE condensing performance with stainless steel fire tube heat exchanger reduces fuel costs in residential heating systems\u003c\/li\u003e\n\u003cli\u003eUp to 5.4 GPM domestic hot water output and 10:1 turndown ratio allow the unit to handle both space heating and on-demand hot water from one appliance\u003c\/li\u003e\n\u003cli\u003eUnity 2.0 color touch screen with setup wizard simplifies commissioning and troubleshooting for HVAC technicians\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Weil-McLain Eco Tec 672619221253 delivers 95% AFUE efficiency, combined space heating and domestic hot water capability, and flexible venting in a wall-mount or floor-mount form factor suited for residential installations.
