Why Go “Tankless?”

  • Efficiency – Your Rinnai Tankless Water Heater captures 84% of the heat energy, ensuring cost-effective operation, and once you turn off the faucet, the tankless unit shuts down and uses no electricity.
  • Save Money! – Tankless or instantaneous water heaters don’t store and repeatedly reheat water like standard units, eliminating standby energy losses and slashing unnecessary costs.
  • Endless Hot Water – When cold water enters the unit, a flow-activated switch triggers heating, bringing water to an ideal temperature as it passes through a copper heat exchanger, delivering a limitless supply.
  • Cleaner Water – Because there is no tank, water doesn’t absorb minerals, providing a fresher, cleaner supply of water.
  • Precise Control – Digital controllers allow you to determine output water temperature for greater comfort and safety.
  • Space Savings – Tankless units are the size of a small suitcase. Compare that to storage tank water heaters that generally require a clearance of 60 inches of height and 24 inches of width, taking up valuable floor space.
  • Why Wait? – No more waiting for water to warm up!
  • Flexible Installation – A compact tankless heater can be conveniently mounted on nearly any wall, inside or outside your home, allowing for the most efficient, advantageous and aesthetic location.
  • Avoid the Flood – You’ll never be confronted by a flooded basement or water damage due to a ruptured or leaking tank.
  • Longer Service Life – Twenty years of reliable service versus ten to thirteen years. Which would you choose?
  • Accessories – Rinnai’s line of digital controllers allows customization of water temperature in multiple locations in the home, analysis and troubleshooting, and even automatically filling of your bath to a pre-set temperature and volume.
