AquaCore
Hot Water Heat Pump

Efficient, flexible hot water—built for New Zealand homes

The Black Diamond AquaCore hot water heat pump delivers reliable, energy-efficient hot water while helping reduce your power bills.

 

Hot water can make up a significant portion of your power bill.

 

The AquaCore system uses proven heat pump technology to heat your water more efficiently—reducing energy use without changing how you use hot water day to day.

 

Designed and tested for New Zealand conditions, it’s a practical, flexible solution for both new builds and upgrades.

Why Choose AquaCore

Lower running costs

Heat pump technology can significantly reduce the electricity required to heat your water compared to traditional systems.

Designed for NZ conditions

Operates in temperatures from -15°C to 45°C, making it suitable year-round.

Efficient performance (COP up to 3.6)

For every 1kW of electricity used, the system can deliver around 3.6kW of heat output.

Environmentally conscious

Uses R32 refrigerant with lower global warming potential.

Fast hot water recovery

Reheats a full tank faster than traditional electric cylinders—so you’re less likely to run out.

Works with existing hot water cylinders

Designed to integrate with new or existing systems, helping reduce installation costs and making upgrades more straightforward.

HOW IT WORKS

The AquaCore system works by extracting heat from the outside air and transferring it into your hot water system.

Instead of generating heat directly like a traditional electric cylinder, it moves existing heat—making it far more energy efficient.

 

The system is made up of:

  • An outdoor unit (absorbs heat from the air)

  • An indoor unit (transfers heat to water)

  • A compatible hot water cylinder

Key Features 

Flexible system design
Works with existing or new cylinders—helping reduce installation costs on upgrades.

Wi-Fi control capability
Control your hot water usage, schedule heating times, and optimise energy use around off-peak rates.

Fast heat-up performance
Top-down heating means usable hot water can be available quickly—even from a cold tank.

 

Quiet operation
Outdoor unit operates from around 49dBA—similar to a quiet indoor environment.

 

Smart control system
Multiple operating modes (Eco, Standard, Disinfect) and programmable timers.
