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.
Heat pump technology can significantly reduce the electricity required to heat your water compared to traditional systems.
Operates in temperatures from -15°C to 45°C, making it suitable year-round.
For every 1kW of electricity used, the system can deliver around 3.6kW of heat output.
Uses R32 refrigerant with lower global warming potential.
Reheats a full tank faster than traditional electric cylinders—so you’re less likely to run out.
Designed to integrate with new or existing systems, helping reduce installation costs and making upgrades more straightforward.
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

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.

The AquaCore system is a great fit if you:
Want to upgrade from an electric or gas hot water system
Prefer a system that can work with your existing cylinder
Need a flexible solution for your home layout
Are looking for a balance of performance and cost
Want reliable hot water year-round in NZ conditions
Not sure which system is right?


AquaCore is designed to integrate with a wide range of existing mains pressure hot water systems.
This makes it a strong option for:
Retrofit installations
Homes where replacing the cylinder isn’t necessary
Situations where flexibility is important
Every home is different. We’ll assess your setup and recommend the best system for your needs.
