Product Description
The Weil-McLain 672619221239 is the Eco Tec 110 MBH condensing gas combination boiler, designed for residential hydronic heating and domestic hot water supply from a single, wall-mounted or floor-mounted unit. This high-efficiency combi boiler delivers an AFUE rating of 95%, meaning it converts 95 cents of every dollar of fuel into usable heat. The stainless steel fire tube heat exchanger is built for durability and long service life, resisting the corrosive effects of condensation that are common in high-efficiency condensing appliances. HVAC technicians and plumbers will appreciate the Unity 2.0 color touchscreen with text-based control and a built-in setup wizard, which simplifies initial commissioning and day-to-day navigation. The boiler runs on natural gas with electronic ignition and operates on single-phase 120V power. It delivers up to 3.0 GPM of domestic hot water at a 70-degree temperature rise, making it well suited for small to mid-size residential applications. The 10:1 turndown ratio allows the unit to self-adjust its firing rate to match actual demand, reducing short cycling and minimizing fuel consumption. The boiler can operate up to two zone circulators and one boiler circulator, covering multi-zone hydronic heating layouts. Venting is flexible, supporting PVC, CPVC, polypropylene, or stainless steel vent pipe in 3-inch diameter up to 100 feet, or 2-inch diameter up to 50 feet. Multi-boiler configurations are supported using an optional wiring kit, which is useful for larger loads or redundant heating setups. The heat exchanger and domestic hot water pipes are insulated to reduce standby heat loss and lower operating noise. An outdoor temperature sensor is included for outdoor reset control, which further improves efficiency by matching supply water temperature to outdoor conditions. The unit holds 2.2 gallons of water and has supply and return pipe connections sized at 1 inch. It is Energy Star compliant, NSF 372 certified, ANSI 372 listed, and UL listed, and it is approved for sale in California under CEC compliance requirements.
