Rinnai Tankless Water Heaters

Save money and splurge on performance with Rinnai tankless water heaters, available at Earl Gray and Sons Plumbing in Indianapolis, IN.

Designed for efficiency, Rinnai’s tankless technology features copper heat exchangers to provide maximum efficiency and easily meet ENERGY STAR® qualifications. Rinnai tankless water heaters use up to 40% less energy than traditional tanks.

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

You can 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.

Rinnai units are available in multiple sizes and give you options to right-size your installation and customize your efficiency. In addition, every part of a Rinnai tankless water heater is replaceable. Components can be easily exchanged, if needed, as opposed to replacing the entire system.

Earl Gray and Sons Plumbing is an Authorized Service Specialist for Rinnai. 

We offer a one year labor warranty in addition to the manufacturer's one year labor warranty. That gives you a two year labor warranty at no additional cost! 6 year extended labor warranties are also available. 

Stay green with a sustainable choice

  • Rinnai’s tankless technology achieves maximum energy efficiency; helping conserve resources.
  • The compact heat-exchanger design, longer product lifespan (compared to traditional tanks) plus recyclable parts mean less waste in landfills.
  • Lower CO2 emissions contribute to cleaner air and a healthier environment.

With a Rinnai tankless water heater, you’ll never have to think about your hot water needs again. Rinnai’s innovative technology provides an endless supply of hot water whenever and wherever needed – even for simultaneous uses at multiple fixtures.

If you are taking a shower or bath at the same time you are running the washing machine and dishwasher, it’s not a problem.

Maximum Output, Minimum Space

Roughly the size of a small suitcase, at 18.5” x 26” x 10” or smaller, a Rinnai tankless water heater can be installed on any wall or in compact spaces. Wall-mounted units can be installed on the interior or exterior wall of the home, freeing up space for other uses.

The small size allows for installation in non-traditional spaces such as crawl spaces and attics. That makes Rinnai tankless water heaters perfect for homes of any size, including manufactured and modular homes.
