Heat Pump Hot Water
Efficient, all-electric hot water for high-performance homes. CO₂ heat pump systems designed and installed by specialists.
Why heat pump hot water?
Hot water is consistently one of the largest energy loads in a home — often rivalling space heating. Heat pump hot water systems address this by extracting heat from ambient air rather than generating it electrically, delivering efficiencies of 300–500% compared to a conventional electric element.
For all-electric, Passive House or solar-powered homes, heat pump hot water is the natural choice. It integrates with solar PV systems to optimise self-consumption, eliminates the need for gas entirely, and dramatically reduces running costs compared to any resistive electric system.
HiPer Haus works with CO₂ (R744) heat pump systems — a natural refrigerant with excellent low-temperature performance and a near-zero global warming potential. CO₂ heat pumps perform well in Adelaide’s climate year-round, including cold winter mornings in the Hills.

Why CO₂ heat pump hot water
Highly efficient
CO₂ heat pumps achieve a Coefficient of Performance (COP) of 3–5, meaning 3–5 units of heat energy for every 1 unit of electricity consumed.
Works in all weather
CO₂ refrigerant allows efficient operation down to very low outdoor temperatures — including Adelaide winters.
Solar compatible
Pair with a solar PV system and use excess generation to heat water during the day. Smart controls optimise solar self-consumption.
All-electric homes
Eliminate gas entirely. Heat pump hot water is the low-energy, low-emission replacement for gas storage systems.
Quiet operation
Modern heat pump units operate at low noise levels, typically suitable for installation near living spaces.
Long service life
Quality CO₂ heat pumps are designed for reliability and long service life with routine maintenance.
