Rinnai Tankless Water Heaters
Imagine endless hot water and low energy bills
Heat water quickly and deliver an endless supply as long as you need it

  • Produce and supply endless streams of hot water to multiple outlets simultaneously without any fluctuation in temperature
  • Up to 30 percent more energy efficient than a traditional natural gas water heater and up to 50 percent more efficient than an electric water heater
  • Shut-off automatically when the water supply is closed, providing users with significant energy savings - in turn saving money on their utility bills
  • Compact wall mounted units with a life expectancy of 20 years, whereas hot water tanks require about 16 square feet of floor space and usually last around 10 years
