Energy Smart Tankless Water Heaters Keep the Hot Water Flowing – Written by Carollyn Farrar, Marketing Program Manager, NW Natural

Over time the technology behind heating water has evolved. Conventional tank water heaters store hot water on a standby basis, heating and reheating the same water as it’s needed. The energy used to heat and reheat is lost in the venting and through the walls of the tank.

Today’s efficient tankless water heater only heats water when it is called for. The main advantage of a tankless water heater is no extra cost of keeping 40 to 50 gallons of water hot in a storage tank, so it uses less energy.

Builders at this year’s Parade of Homes selected two brands of condensing tankless natural gas water heaters to serve their homes. The condensing feature allows the heat exchanger to capture and reuse heat from the exhaust to enhance energy efficiency and provide energy savings.

Be sure to check out the home built by Cascade West Development Construction, for the newest in tankless technology from Rinnai®.  It’s called SENSEI™.  All SENSEI™ models feature recirculation for faster hot water and Wi-Fi compatibility, so they can be controlled and monitored remotely from a smart device. And at 11 gallons per minute, SENSEI™ RU199iN can provide plenty of hot water for bathing, cooking, dishes, and laundry.

Next, check out the tankless water heater featured in the homes built by Cascade West Development and Soaring Eagles Homes. It’s the Navien condensing unit, featuring a new approach on ease of use for the homeowner.  The front side displays the inside water temperature so it can be adjusted and controlled by simple arrows to ensure against burns from water too hot for family members.  The Intelligent Preheating Technology recognizes how the family uses hot water and will preheat it before it’s called for.

Both the SENSEI™ and the Navien take up a small amount of space, about the size of a suitcase, and can be installed in doors or outside.

Top five benefits of choosing a natural gas tankless water heater:

  • Plenty of hot water when needed
  • Longer life, lasting five to 10 years longer than tank water heaters
  • More efficient with no extra cost of keeping water hot in a storage tank
  • Suitcase sized, it can be installed in a closet, closer to the point of use
  • No possibility of flooding due to a leaking tank
