ULTRA SERIES: Tankless Water Heater

Delivering our most energy-efficient performance, the Ultra Series features a condensing design with two heat exchangers to maximize heating value to enhance reliability and durability and reduce maintenance.

Save Money, Splurge on Performance

Designed for efficiency: Rinnai’s tankless technology features copper heat exchangers to provide maximum efficiency and
uses up to 40 percent less energy* than a traditional tank.

Save energy: By operating only when hot water is needed, and no storage tank to heat and reheat water, our tankless
technology helps save on energy and utility costs. The use of an electronic ignition means no standing pilot light that constantly
uses energy.

A smart investment: Increase your home’s value with premium technology, increased energy efficiency, an improved Home
Energy Rating System (HERS) Index Score and optimized LEED certification. Available energy efficiency rebates and tax credits
offer the opportunity to help make your purchases more affordable.

Multiple sizes: Rinnai gives you options to right-size your installation and customize your efficiency.

Replace parts, not systems: Every part of a Rinnai Tankless Water Heater is replaceable. Components can be easily
exchanged, if needed, versus replacing the entire system.

Save Space with a Compact Design

Maximum output, minimum space: About the size of a small suitcase at 18.5” x 26” x 10” or smaller, these wall-mounted
models can be installed on interior or exterior walls and in compact spaces to free up valuable space.

Flexible installation: Small size allows for installation in non-traditional spaces such as crawl spaces and attics, making it
perfect for use in any size home, including manufactured and modular homes.

Stay Green with a Sustainable Choice

Earth-friendly efficiency: Our tankless technology achieves maximum energy efficiency, helping to conserve natural

Less waste: Compact heat exchanger design, longer product lifespan up to twice as long as a traditional tank** and recyclable
parts means less waste in landfills.

High standards for low emissions: Lower CO2 emissions contribute to cleaner air and a healthier environment.
