Rinnai Tankless Water Heaters & Boilers

Have hot water whenever you need it
You don’t have to worry about running out of hot water again. Our innovative technology provides an endless supply of hot water whenever and wherever it’s needed – even for simultaneous uses at multiple fixtures. Back-to-back showers and baths? Absolutely. Laundry and dishes at the same time? No problem. Prioritizing activities and scheduling hot water use is a thing of the past.

Save money
» Designed for efficiency: Rinnai’s tankless technology features durable 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, with pilot light 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 for now and the future: 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.

» Customize your efficiency: Rinnai gives you installation options that are the perfect fit for nearly any home.

» 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.

Regain more 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: Our tankless technology achieves maximum energy efficiency, helping to conserve natural resources. And with higher standards for lower CO2 emissions, they contribute to a  healthier

» 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.
