Description
Rinnai I-Series Plus IP120199C Combi Boiler – High-Efficiency Heating & Hot Water in One
The Rinnai I-Series Plus IP120199C combi condensing boiler is designed to handle both space heating and domestic hot water from a single, wall-hung appliance. With up to 120,000 BTU/h for heating and 199,000 BTU/h for hot water, it is a powerful, high-efficiency solution for many mid- to large-size homes in the Greater Toronto Area.
If you’re looking to replace an older boiler and separate water heater, or you want to convert from a conventional system to a modern hydronic combi setup, the IP120199C offers outstanding performance, compact design and long-term energy savings.
Key Benefits at a Glance
- High-efficiency condensing combi boiler – designed to deliver excellent fuel savings compared to older non-condensing equipment.
- Space heating input: up to 120,000 BTU/h (modulating burner for better comfort and efficiency).
- Domestic hot water input: up to 199,000 BTU/h, with strong flow for multiple bathrooms and fixtures.
- Wall-hung, compact design – frees up valuable floor space in mechanical rooms and basements.
- Multi-zone capability – built-in support for multiple heating zones (when piped and controlled correctly).
- Smart combustion controls – automatically optimize gas usage and help maintain stable performance.
- Quiet operation – designed for low sound levels in everyday use.
High-Efficiency Space Heating
At the heart of the IP120199C is a condensing stainless-steel heat exchanger that extracts more heat from the combustion process by using low return-water temperatures. This allows the boiler to reach high efficiency levels when paired with properly designed hydronic systems.
The burner can modulate across a wide range, so on mild days it runs at lower input levels instead of constantly cycling on and off. That modulation:
- Improves comfort by reducing temperature swings.
- Helps extend component life by reducing hard starts and stops.
- Supports lower gas consumption over the season.
The unit can be applied to a variety of hydronic heating systems, including:
- Radiant in-floor heating.
- Panel radiators and baseboard radiators.
- Hydronic air handlers and fan coils.
- Multi-zone manifolds for different floors or areas.
Powerful On-Demand Domestic Hot Water
As a combi boiler, the Rinnai IP120199C also functions as a high-output tankless water heater. With up to 199,000 BTU/h dedicated to domestic hot water, it can provide a generous flow of hot water for:
- Multiple full bathrooms.
- Showers, tubs and sinks running at the same time (within design limits).
- High-demand households that frequently use hot water for laundry and dishwashing.
Because the system produces hot water on demand, you are not storing a large volume of heated water in a tank, which can reduce standby losses and free up space previously occupied by a traditional tank-type heater.
Smart Controls & Zoning
The I-Series Plus platform includes advanced control logic to get the most out of the boiler in real-world conditions. Key features typically include:
- Built-in multi-zone support – allows you to connect multiple heating zones so different floors or areas can have their own thermostats and comfort settings.
- Outdoor reset control – the boiler can automatically adjust water temperature based on outdoor conditions, saving energy while maintaining comfort.
- Intelligent modulation – the boiler adjusts its firing rate to match the actual heating load, rather than running at full input all the time.
- Diagnostic display – onboard screen and codes make maintenance and troubleshooting easier for technicians.
With the right controls and thermostats, this gives Greater Toronto homeowners much finer control over comfort and energy usage compared to legacy boilers.
Compact, Wall-Hung Design
The Rinnai IP120199C is wall-mounted and designed to be compact, making it an excellent fit for tight spaces:
- Basements and mechanical rooms where floor space is limited.
- Utility closets in townhomes or smaller urban homes.
- Upgrades where you want to reclaim space from bulky old boilers and tanks.
The front-access design makes servicing easier, and the clean, modern cabinet is much more visually appealing than older cast-iron boilers.
Quiet, Reliable Operation
Modern Rinnai combi boilers are engineered for low noise levels and dependable performance. The fan, burner and pump assembly are designed to keep sound to a minimum, which is especially important if your mechanical space is near living areas, bedrooms, or finished basements.
With proper installation and routine maintenance, the IP120199C is built to deliver years of reliable heating and hot water.
Ideal Applications in the Greater Toronto Area
The Rinnai I-Series Plus IP120199C combi boiler is a strong option for:
- Mid- to large-size detached homes with multiple bathrooms.
- Homes currently using a boiler plus a separate tank-type water heater and looking to consolidate to a single high-efficiency unit.
- Renovations or new builds that want modern hydronic heat (radiant floor, baseboard, or fan coils) and on-demand domestic hot water.
- Owners looking to reduce gas consumption and free up mechanical room space.
