Product Description
The RINNAI IP090199CN is a dual-function hydronic combi condensing gas boiler designed to deliver both space heating and domestic hot water from a single unit. 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.
The 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.
Key Features
- 90 MBH hydronic heating output for whole-home space heating
- 4.1 GPM domestic hot water delivery at 70 degrees F temperature rise
- Stainless steel heat exchanger for corrosion resistance and long service life
- Fully modulating burner reduces short-cycling and improves fuel efficiency
- Built-in freeze protection for added reliability in cold-climate installs

- Integrated controls simplify commissioning and diagnostics
Compatibility
Designed as an OEM-style unit for residential hydronic heating and domestic hot water systems requiring a single combi boiler solution.
