Why Choose Tank vs Tankless

Energy Efficiency

Tankless water heaters are 24–34% more energy efficient than traditional tank systems.* Why? Because unlike tank heaters, they don’t store hot water—they heat it only when you need it. This “on-demand” system eliminates standby heat loss, which occurs in traditional tanks that constantly keep water warm, 24/7, regardless of use.

Lower Operational Costs

While tankless units typically have a higher upfront cost, their lower energy consumption leads to significant savings over time. According to industry data, American homeowners spend $400–$600 annually to heat water for everyday tasks like bathing, washing dishes, and cleaning. 

Extended Lifespan

Rinnai’s proprietary Adaptive Gas Valve Technology adjusts to either Natural Gas or Liquid Propane Gas for optimal combustion - no conversion kit required.
