It produces 90 MBH of heating output and supplies up to 4.1 GPM of domestic hot water at a 70 degrees F temperature rise. A stainless steel heat exchanger and fully modulating burner work together to maximize fuel efficiency and maintain stable temperatures across both functions. Licensed HVAC technicians and plumbers install this unit in residential applications where space and equipment count are priorities.\u003c\/p\u003e\n\u003cp\u003eThe IP090199CN is built for residential hydronic heating systems that also require on-demand domestic hot water. Its integrated design eliminates the need for a separate water heater, reducing mechanical room footprint. The I-Series Plus platform supports flexible venting configurations, making it suitable for both new construction and retrofit installations where venting access may be limited. Built-in controls and freeze protection add operational reliability in seasonal or low-occupancy settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90 MBH hydronic heating output for whole-home space heating\u003c\/li\u003e\n  \u003cli\u003e4.1 GPM domestic hot water delivery at 70 degrees F temperature rise\u003c\/li\u003e\n  \u003cli\u003eStainless steel heat exchanger for corrosion resistance and long service life\u003c\/li\u003e\n  \u003cli\u003eFully modulating burner reduces short-cycling and improves fuel efficiency\u003c\/li\u003e\n  \u003cli\u003eBuilt-in freeze protection for added reliability in cold-climate installs\u003c\/li\u003e\n  \u003cli\u003eFlexible venting options support a range of installation configurations\u003c\/li\u003e\n  \u003cli\u003eIntegrated controls simplify commissioning and diagnostics\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style unit for residential hydronic heating and domestic hot water systems requiring a single combi boiler solution.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a licensed HVAC technician or plumber in accordance with local mechanical codes, the IFGC, and applicable plumbing codes. Shut off gas supply and isolate all hydronic and potable water connections before servicing. Follow the manufacturer venting guidelines for proper flue sizing and termination clearances. Do not operate the unit without verifying gas supply pressure and confirming all water connections are leak-free.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeating Output\u003c\/strong\u003e: 90 MBH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDomestic Hot Water Flow Rate\u003c\/strong\u003e: 4.1 GPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDHW Temperature Rise\u003c\/strong\u003e: 70 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeat Exchanger Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBurner Type\u003c\/strong\u003e: Fully Modulating\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBoiler Type\u003c\/strong\u003e: Condensing Combi Gas Boiler\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: I-Series Plus\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: RINNAI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: IP090199CN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RINNAI","offers":[{"title":"Default Title","offer_id":51346884395314,"sku":"IP090199CN","price":4324.78,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310554814.jpg?v=1782093504","url":"https:\/\/voomisupply.com\/products\/rinnai-ip090199cn-combi-condensing-gas-boiler-90-mbh","provider":"Voomi Supply","version":"1.0","type":"link"}
