Rinnai is raising the bar in tankless heating technology with their SENSEI tankless water heaters. Rinnai's SENSEI series provides a better experience for both users and installers alike with simple installation, serviceability, efficient performance, and flexible venting options. The SENSEI's advanced condensing technology can easily adapt to colder climates with freeze protection down to -4 degrees fahrenheit for outdoor units. A corrosion-resistant stainless steel heat exchanger, integrated check valve, and included safety devices allow for powerful and efficient water heating for years to come.


Continuous Water for Multiple Applications 
Rinnai tankless water heaters provide an endless supply of hot water that remains uninterrupted, even when you're the last one in line for the shower.

Energy Efficient Promise 
Tankless water heaters avoid the need to keep a large amount of reserve water heated at all times. This saves energy by only heating water when you need it, while an entirely electric ignition avoids the constantly wasted energy of a standing pilot light.

Wi-Fi Compatible 
Every SENSEI water heater is Wi-Fi compatible for remote monitoring and management.

Enhanced Combustion Design 
The Rinnai SENSEI series water heaters feature a fiber mesh premix burner that provides an even flame distribution for optimal performance and efficiency.

Stainless Steel Heat Exchanger 
The included stainless steel heat exchanger features corrosion-resistant properties to ensure reliable and long-lasting operation, while its superior efficiency puts the SENSEI series at the top of its class.

Flexible Venting Options 
Perfect for both new installs and retrofits, the SENSEI features the most flexible venting in the industry. Whether your install requires concentric, direct, room air, or common venting, the SENSEI series can handle it all.

Simple Installation and Serviceability 
The SENSEI water heater features an adjustable mounting plate and a rotatable pressure relief valve to accommodate a variety of install applications. An easily accessible control panel and parameter adjustment allow for fast and simple servicing.

PVC Vent capable
Installation Placement

Equipment can be placed inside or outside of the home.

Installation Placement
Maximum Input BTU

The maximum amount of heat that the unit can produce. The amount delivered into the space will be the input minus the efficiency loss also know as the output. For example a 100000 btu furnace at 80% efficiency will give you 80000 out btus of heat. The same size furnace at 95% will give you 95000 btus of heat.

Maximum Input BTU
160000 BTU
Minimum Input BTU

The amount of heat produced by the unit at the lower stage of heat. Having two stages of heat will allow for more consistent operation and greater comfort in the home.

Minimum Input BTU

ENERGY STAR® Qualified

Products earn the ENERGY STAR label by meeting the energy efficiency requirements set forth in ENERGY STAR specifications. The EPA establishes these specifications based on the following set of principles:

  • Product categories must contribute significant energy savings nationwide.
  • Qualified products must deliver the features and performance demanded by consumers, in addition to increased energy efficiency.
  • If the qualified product costs more than a conventional, less-efficient counterpart, purchasers will recover their investment in increased energy efficiency through utility bill savings, within a reasonable period of time.
  • Energy efficiency can be achieved through broadly available, non-proprietary technologies offered by multiple manufacturers.
  • Product energy consumption and performance can be measured and verified with testing.
  • Labeling would effectively differentiate products and be visible for purchasers.
