Description

Rinnai I-Series Plus IP120S Solo Boiler – High-Efficiency Hydronic Heating for GTA Homes

The Rinnai I-Series Plus IP120S is a heat-only condensing gas boiler designed for reliable, high-efficiency hydronic heating. With up to 120,000 BTU/h of heating input, built-in zoning and advanced controls, it is an excellent choice for mid- to large-size homes in the Greater Toronto Area that want quiet, even comfort from a modern boiler system.

Wall-hung, compact and ultra-efficient, the IP120S replaces bulky, older boilers with a sleek unit that takes up less space while delivering better comfort and lower gas consumption.

Key Features & Benefits

• Heat-only design – dedicated to central heating; pair with an indirect tank if you want a separate, high-performance hot water solution.
• 120,000 BTU/h heating input – ideal for many 2,000–3,000+ sq. ft. homes (final sizing based on heat-loss calculation).
• Condensing stainless-steel heat exchanger – captures more heat from exhaust gases for excellent efficiency.
• Up to mid-90s AFUE efficiency – significantly higher than older non-condensing boilers.
• 4 built-in heating zones – better comfort control for different floors or areas of your home.
• 7 heating reset curves – automatically adjusts boiler output based on outdoor temperature for consistent comfort and reduced energy use.
• Smart Sense™ adaptive gas valve – automatically adjusts for natural gas or propane for optimal combustion.
• Smart Connect™ + app support – Bluetooth® connectivity for quick setup and parameter adjustments via mobile app (with compatible hardware).
• Ultra low NOx, ENERGY STAR® rated – cleaner, more environmentally friendly operation.

Smooth, Even Hydronic Heating

The IP120S uses a modulating burner and advanced control logic to match its output to the actual heating demand. Instead of cycling on and off at full power, it ramps up and down as needed to:

• Reduce temperature swings and cold spots.
• Improve efficiency during mild weather.
• Extend component life by limiting hard starts and stops.

Paired with properly designed hydronic distribution, this boiler can deliver gentle, even heat that feels more comfortable than typical forced-air systems.

Compatible with a Wide Range of Hydronic Systems

The Rinnai IP120S works with many common hydronic applications, including:

• Radiant in-floor heating (slab or underfloor systems).
• Panel radiators and baseboard radiators.
• Hydronic air handlers and fan coils (for homes that still want ducted air delivery).
• Indirect water heaters, if you prefer a dedicated hot water storage tank.

This flexibility makes it a strong option for both new construction and retrofits where an older boiler is being replaced.

Built-In Zoning & Outdoor Reset

All I-Series Plus models include features that are normally add-ons with many older boilers:

• 4 built-in zones – simplifies piping and controls for multi-zone systems; each zone can be controlled with its own thermostat and circulator/zone valve (when set up correctly).
• 7 heating reset curves – the boiler automatically lowers water temperature on milder days and increases it during deep cold snaps, helping reduce gas use while still keeping your home comfortable.
• Outdoor reset sensor – monitors outdoor temperature so the boiler can anticipate load changes instead of reacting after the home cools down.

For Greater Toronto’s variable winters, these features are crucial for balancing comfort and efficiency.

Compact, Wall-Hung Footprint

The Rinnai IP120S has a slim, wall-mounted cabinet (approx. 26.4″ H × 18.5″ W × 11.5″ D), which:

• Frees up floor space compared to old cast-iron boilers and tanks.
• Makes it easier to install in tight mechanical rooms, closets, or urban basements.
• Improves service access – components are accessible from the front.

It’s a strong fit for Toronto and GTA homes where mechanical space is at a premium.

Quiet, Clean Operation

The IP120S is engineered for low noise levels and clean combustion:

• Sealed direct-vent design helps keep combustion air separate from indoor air.
• Low NOx burner helps reduce emissions while maintaining high efficiency.
• Well-insulated cabinet and advanced fan/burner design help keep sound levels down, making it suitable for installations near finished spaces.

Wi-Fi Capable with Smart Controls

I-Series Plus boilers are Wi-Fi capable with the appropriate connectivity kit, enabling:

• Quick setup and parameter configuration using a mobile app.
• Access to system information for easier troubleshooting and service.
• Integration with compatible smart controls and thermostats for more advanced scheduling and energy management.

This makes the IP120S a forward-looking choice for homeowners who want both performance and modern visibility into how their heating system is running.

Ideal Applications in the Greater Toronto Area

The Rinnai I-Series Plus IP120S Solo Boiler is a great match for:

• Mid- to large-size detached homes and semi-detached homes with higher heating loads.
• Multi-zone hydronic systems where different floors or sections of the house need independent control.
• Upgrades from old, mid-efficiency or cast-iron boilers to a modern condensing system.
• Projects where you want to pair a high-efficiency boiler with an indirect tank for domestic hot water.
