It delivers 120,000 BTU per hour of heating input with a rated output of 112,000 BTU per hour, achieving an Annual Fuel Utilization Efficiency of 95.0%. That rating means the boiler converts 95 cents of every dollar of natural gas into usable heat, keeping fuel costs low over the life of the unit. The 10-to-1 turndown ratio allows the burner to modulate output from full capacity down to just 10 percent of its rated input. This wide range of modulation lets the boiler match actual heat demand in real time, reducing short cycling and improving comfort in residential hydronic heating systems.\u003c\/p\u003e\u003cp\u003eThe heat exchanger is made from 316L stainless steel using a single-tube, large-diameter design. This construction resists corrosion from hot water contact and supports long service life. The 316L alloy is a standard choice in high-efficiency condensing boilers because it handles the low flue gas temperatures and mild condensate acidity that occur during condensing operation. Spark ignition handles lighting automatically without a standing pilot, which eliminates the continuous gas draw of older pilot-based systems.\u003c\/p\u003e\u003cp\u003eInstallation uses 3\/4-inch supply and return pipe connections. The unit runs on 120V single-phase power. Venting is compatible with PVC, CPVC, stainless steel, or select polypropylene materials, giving installers flexibility based on job conditions. The compact wall-mount footprint opens up placement options where floor space is limited. Removable side panels make routine service, cleaning, and inspection straightforward. The boiler ships with a water treatment inhibitor and test kit to protect the heat exchanger from day one. Controls are simple and user-friendly for both initial setup and ongoing adjustments. The unit is Energy Star compliant and certified for sale in California under CEC standards. CSA certified for safety compliance.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e95% AFUE natural gas condensing boiler with 120,000 BTU input and 112,000 BTU heat output\u003c\/li\u003e\n\u003cli\u003e10-to-1 turndown ratio with spark ignition for precise modulation and efficient operation\u003c\/li\u003e\n\u003cli\u003e316L stainless steel single-tube heat exchanger compatible with PVC, CPVC, stainless steel, or polypropylene venting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Weil-McLain AquaBalance Series 2 delivers 95% AFUE efficiency with a wide modulating range and a corrosion-resistant stainless steel heat exchanger in a compact wall-mount design suited for residential hydronic heating installations.\u003c\/p\u003e\u003ch3\u003eProduct Information\u003c\/h3\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WEIL-MCLAIN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 672619210233\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollection\u003c\/strong\u003e: AquaBalance Series 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Residential\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel Type\u003c\/strong\u003e: Natural Gas\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMedia\u003c\/strong\u003e: Hot Water\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation Type\u003c\/strong\u003e: Wall Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBTU Input\u003c\/strong\u003e: 120,000 BTU per hour\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBTU Heat Rating\u003c\/strong\u003e: 112,000 BTU per hour\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput (MBH)\u003c\/strong\u003e: 120 MBH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAFUE\u003c\/strong\u003e: 95%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTurndown Ratio\u003c\/strong\u003e: 10 to 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIgnition System\u003c\/strong\u003e: Spark Ignition\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVolts\u003c\/strong\u003e: 120V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhase\u003c\/strong\u003e: Single Phase\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupply Pipe Connection Size\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReturn Pipe Connection\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 27.56 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 16.54 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDepth\u003c\/strong\u003e: 12.6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnergy Star Compliant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCEC Compliant\u003c\/strong\u003e: For Sale in CA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCSA Certified\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WEIL-MCLAIN","offers":[{"title":"Default Title","offer_id":53869705298247,"sku":"672619210233","price":2380.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0967\/5643\/3223\/files\/304883532.jpg?v=1778097232","url":"https:\/\/valonta.shop\/products\/weil-mclain-672619210233-aquabalance-series-2-hot-water-gas-boiler-120-mbh-heat-only-stainless-steel-single-tube-heat-exchanger-95-afue","provider":"Trakzota","version":"1.0","type":"link"}
