How Rinnai hot water heat pumps work

Rinnai heat pump systems use energy from the air to heat your water efficiently:

  1. Heat is drawn from the surrounding air
  2. It is compressed to increase temperature
  3. That heat is transferred into your water cylinder

This process significantly reduces electricity use compared to traditional systems.
