Tankless Water Heater

Rinnai Tankless Solutions Give You the Power to Live Better

An endless supply of hot water, whenever you need it—even for multiple tasks at the same time. Tankless Water Heaters revolutionize comfort, energy efficiency and convenience.

Save money, splurge on performance.

Designed for efficiency: Rinnai’s tankless technology features copper heat exchangers to provide maximum efficiency, and easily meet ENERGY STAR® qualifications 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 igntionmeans no standing pilot light that constantly uses energy.

A smart investment: Increase your home’s value with premium technology, energy efficiency and an improved Home Energy Rating System (HERS) index score. 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.
