Enjoy an endless supply of hot water with the SENSEI™ RSC160iN Super High Efficiency Plus condensing tankless water heater from Rinnai. Only the size of a small suitcase, the natural gas RSC160iN model is compact, easy-to-install and perfect for indoor locations.

The Rinnai Sensei Series with condensing technology offers built-in freeze protection down to -22°F on the indoor units. The unit features an integrated check valve located between the turbofan and the combustion chamber to prevent cold air from entering the venting system and backflow of exhaust in common vent applications. The Fiber Mesh Premix Burner helps to provide even flame distribution for optimal performance for any demand.

In a condensing tankless water heater, such as the RSC160, once you turn on the tap, cold water goes into the tankless heater and the flame is activated. Water is pre-heated as it passes through the primary stainless steel heat exchanger then continues to be heated as it passes through the coils in the secondary heat exchanger, exits the water heater, into your pipes, and up to the fixture calling for the hot water. Depending on the amount of hot water called for, the flame adjusts accordingly to heat more or less water.

CIRC-LOGIC RECIRCULATION TECHNOLOGY

Rinnai Circ-Logic recirculation technology allows users to set recirculation patterns that coincide with their hot water usage patterns. Hot water is available when needed, without the expense of circulating it during times of inactivity. Two recirculation modes are available:

• Dedicated Mode - With a dedicated return line, the integrated pump recirculates water from the tankless water heater through the return line and back to the heater.
• Crossover Mode - In applications where a dedicated return line is not available or is difficult to install, Circ-Logic technology allows for the simple installation of a Thermal Bypass Valve (included with purchase) at the fixture farthest away from the water heater
  
  
• Intelligent Recirculation “learns” users’ hot water patterns to schedule recirculation.
