It protects conventional boilers by keeping the boiler return water temperature above the point where flue gas condensation forms.\u003c\/p\u003e\u003cp\u003eInstalled in the boiler loop, the valve bypasses hot supply water back to the boiler return until the return temperature reaches the setting, then gradually opens to the system return. This shortens warm-up time and reduces the corrosion and scaling caused by flue gas condensation in non-condensing cast iron and steel boilers, as well as wood and solid-fuel boilers.\u003c\/p\u003e\u003cp\u003eBefore ordering, confirm the 1-1\/4\" sweat connection and that a 140F return temperature setting suits your boiler manufacturer's requirements. This is a boiler protection valve, not a potable water tempering valve.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Caleffi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part #:\u003c\/strong\u003e 280976A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Anticondensing Thermostatic Mixing Valve\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 1-1\/4\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection:\u003c\/strong\u003e 1-1\/4\" Sweat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Setting:\u003c\/strong\u003e 140F (fixed)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax Pressure:\u003c\/strong\u003e 150 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Pattern:\u003c\/strong\u003e 3-Way\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 8016615377453\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Mixing Valve - Thermostatic\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDocuments\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/res.cloudinary.com\/dzhpkjoqj\/Caleffi\/280976A_CALE-280976A_8016615377453_TechB.pdf\" target=\"_blank\" rel=\"noopener\"\u003eTechnical Data Sheet\u003c\/a\u003e (PDF)\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/res.cloudinary.com\/dzhpkjoqj\/Caleffi\/280976A_CALE-280976A_8016615377453_Inst.pdf\" target=\"_blank\" rel=\"noopener\"\u003eInstallation \u0026amp; Operation Manual\u003c\/a\u003e (PDF)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eSee also: \u003ca href=\"\/collections\/mixing-valve-thermostatic\"\u003emixing valve - thermostatic\u003c\/a\u003e, \u003ca href=\"\/collections\/caleffi-north-america\"\u003eall Caleffi products\u003c\/a\u003e.\u003c\/p\u003e","brand":"Caleffi","offers":[{"title":"Default Title","offer_id":50517447540839,"sku":"CALE-280976A","price":423.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0651\/2253\/3479\/files\/280965A.jpg?v=1792425128","url":"https:\/\/www.thehousesupplier.com\/products\/caleffi-280976a-thermoprotec-anticondensing-thermostatic-valve-1-1-4-sweat-140f-setting","provider":"The House Supplier","version":"1.0","type":"link"}
