All About Tankless Water Heaters

Have you heard about a tankless water heater? Wonder what it is or how it works? What are the benefits of a tankless water heater are?

Then this blog is for you!

Tankless water heaters, or on demand water heaters, are simply a home water heating appliance that doesn’t store your hot water, however, heats the water as it passes through it.

Tankless water heaters are very popular, and they should be. They have so many benefits and last twice as long as a conventional tank; more if maintained properly.

How does a Rinnai Tankless Water Heater Work?
  • When the need for hot water arises by turning on a shower, washing machine, dishwasher or faucet, cold water flows into the Rinnai Tankless Water Heater from the inlet pipe at the bottom of the heater.
  • The flame is ignited and heats the two heat exchangers that are included in the Super High Efficiency models.
  • Water is preheated as it passes through a stainless steel heat exchanger, capturing any extra heat (or latent heat) before it escapes into the vent system.
  • Water continues to be heated as it passes through the heat exchanger, and exits from the hot water outlet pipe to travel through the pipes of the home to the water fixture where hot water is needed.
  • The tankless water heater will adjust flame output as needed to ensure the temperature set point is maintained.
  • As the hot water fixture shuts off, cold water stops flowing into the tankless water heater and the flame extinguishes. The tankless water heater is now off until the next time hot water is needed!
