    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. 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.
