How Tankless Water Heaters Work

How a Tankless System Works

This technology allows for your home’s cold water to be heated only when you need it, and it stays hot until you’re done using it. This results in a limitless hot water supply and little to no wasted energy usage.

Here is how a tankless hot water system works, which occurs in a matter of seconds:

  1. Flame ignites and heats two heat exchangers.
  2. Water preheats as it passes through the secondary heat exchanger.
  3. Water continues to heat to desired temperature as it passes through stainless steel primary heat exchanger.
  4. Water exits the unit and travels to the water fixture where it is needed.
  5. Flame output adjusts as needed to maintain water temperature during use.
  6. With usage complete, the flame turns off and water stops flowing.

Tankless water heaters can work with both natural gas and propane heat sources. If your home happens to run on all-electric heat, tankless may still be a viable option.
