Rinnai RXP160 Tankless Water Heater, Recirculation Pump Built-In

  • Right-Sized Power (9.0 GPM): Don't pay for overkill. This unit generates enough hot water to run up to 2 showers simultaneously—perfect for the average 3-bedroom home with up to 2 bathrooms in Ontario—at a lower equipment cost than the 199-series.

  • Engineered for Ontario Winters: Unlike smaller 120k BTU units, the RX160iN’s 160,000 BTU burner has the muscle to flash-heat freezing groundwater during February, ensuring your showers stay steaming hot year-round.

  • The Condo & Townhouse Specialist: Space is premium real estate. The RX160iN’s compact footprint fits easily in tight mechanical rooms or closets and vents with standard PVC, making it the ultimate space-saving upgrade from bulky tanks.

  • Super High Efficiency (0.97 UEF): Rated as Energy Star® Most Efficient, it captures 97% of heat energy. This drastic reduction in gas usage helps the unit pay for itself over time compared to renting inefficient tanks.

  • Commercial-Grade Durability: Built with a 444 Stainless Steel heat exchanger for superior resistance to scale and corrosion, ensuring long-term reliability.

  • Future-Proof Flexibility: While efficient out of the box, it is Recirculation Capable, allowing you to upgrade with an external pump later if your needs change.

  • The 4Most Pro Installation Advantage: We don't just hang the unit; we optimize it. Our "Supply & Install" package includes gas load verification to prevent system starvation and Smart Sense™ technology setup, ensuring your unit runs safely and efficiently on Natural Gas or Propane from day one.

Sizing Guide

Ideal For:

  • Small to Medium Homes (Max 1,800 sq. ft.) with up to 2 bathrooms in Ontario.
  • Small Families (up to 3 people) with standard daily usage.
  • Replacing Standard Tanks (specifically 40-gallon standard vented tanks).
  • Condos, Townhomes, and Semis where space is limited.

Not Ideal For:

  • Homes demanding "Instant" Hot Water: If you want immediate hot water at the tap, choose the RXP160iN (Pump Model).
  • Large Luxury Homes: Homes with 4+ bathrooms or high-flow luxury showers should step up to the RX199iN for higher volume.
  • Combi-Applications (Heating + Hot Water): For home heating via an air handler, we recommend the higher-capacity RX199iN to ensure sufficient BTU output for both heating and hot water demands.
