Ensure You Always Have Hot Water Available

A Rinnai tankless water heater ensures unlimited hot water for showers, laundry, and dishes simultaneously.


Space Saving Design

Compact and powerful, these suitcase-sized wall units maximize living space by fitting discreetly into tight areas, eliminating the risk of leaks from large water storage and offering easily replaceable parts over full unit replacement.

Superior Value Compared to a Tank

Rinnai tankless water heaters offer double the lifespan and warranty, energy savings by heating water on demand, and often come with consumer financing and rebates.


Unmatched Reliability

Rinnai tankless water heaters undergo individual quality tests before shipping, with most key components made in-house for consistent quality control. This commitment to quality makes Rinnai the preferred choice for consumers.
