How Rinnai hot water heat pumps work
Rinnai heat pump systems use energy from the air to heat your water efficiently:
- Heat is drawn from the surrounding air
- It is compressed to increase temperature
- That heat is transferred into your water cylinder
This process significantly reduces electricity use compared to traditional systems.
Rinnai heat pump options
Rinnai offers a range of systems designed for different household needs:
- Integrated systems (all-in-one unit)
- Split systems (ideal for certain layouts or retrofits)

Is Rinnai better than other heat pump brands?
