How Do Rinnai Heat Pump Hot Water Systems Work?

Your Rinnai system works by:

  • Extracting heat from the air using the heat pump unit (usually installed outside).
  • This heat is transferred to your water storage tank via refrigerant technology.
  • Storing hot water in an insulated tank until needed.
  • Activating an electric booster when extra heating is required during cold days or high demand.

This Rinnai water heating process reduces electricity use compared to traditional electric heaters.
