The physics and mechanics of turning cold water into hot showers 

 

Step by step:

  • When hot water is needed, turning on a shower, washing machine, dishwasher, or faucet, cold water flows through the Rinnai Tankless Water Heater from the inlet pipe to the bottom of the heater.
  • The flame ignites and heats two heat exchangers included in the Super-High- Efficiency models.
  • Preheated water passes through a stainless steel heat exchanger capturing any extra or latent heat before it escapes through the vent system.
  • Water continues to be heated as it passes through the copper heat exchanger and exits from the water heater outlet pipe to travel through the pipes through the home, wherever hot water is needed.
  • The tankless water heaters adjust the flame output to insure the temperature set point is maintained.
  • When the hot water fixtures shuts off, cold-water stops flowing through the tankless system and the flame diminishes.

Your water heater is now off until the next time you want hot water. No more heating unused water.
