Performance-Grade Hot Water Heat Pump Systems

designed to efficiently transfer heat from the surrounding air for everyday hot water heating.

Smarter Hot Water Starts Here

Hot water is used every day for showering, cleaning and other household needs, making water heating an important part of a home's ongoing energy consumption.

Unlike conventional electric cylinders that create heat directly from electricity, a hot water heat pump captures existing thermal energy from the surrounding air and transfers it into the water. This allows the system to deliver more heat energy than the electrical energy it consumes.

LBP Direct supplies performance-grade hot water heat pump systems selected for efficient operation across the wide range of temperatures experienced throughout New Zealand.

Benefits of Hot Water Heat Pump Technology

Improved Energy Efficiency

Heat pump technology transfers existing heat instead of generating all of its heat directly from electricity.

Improved Operating Efficiency

By transferring existing heat from the surrounding air, hot water heat pumps can deliver significantly more heat energy than the electrical energy they consume.

Everyday Hot Water Heating

Designed to efficiently provide hot water for the everyday needs of modern homes.

Suitable for New Zealand Conditions

Our systems are optimised to operate across ambient temperatures ranging from −10°C to 45°C.

Efficient Performance

Depending on operating conditions, the system can deliver several units of heat energy for every unit of electricity consumed.

Strong Warranty Protection

Heat pump units include a five-year warranty, while premium stainless-steel cylinders include an 18-year warranty, subject to maintenance conditions.

How a Hot Water Heat Pump Works

Benefits of Hot Water Heat Pump Technology

Conventional electric water cylinders generate heat directly and generally operate close to a COP of 1.0. This means they produce approximately one unit of heat for each unit of electricity consumed.

Hot water heat pumps collect and transfer existing heat from the air. Depending on the system and operating conditions, a quality heat pump may achieve a COP between approximately 2.5 and 4.0.

Understanding COP
Coefficient of Performance compares the heat energy delivered by a system with the electricity it consumes. A higher COP indicates greater operating efficiency.


COP 4.30 at 15°C ambient temperature
COP 3.84 at 7°C ambient temperature


Actual performance varies according to ambient temperature, water demand, installation conditions and system configuration.

Frequently Asked Questions

Does a hot water heat pump work during winter?

Yes. The systems offered by LBP Direct are designed to operate in ambient temperatures ranging from −10°C to 45°C. Efficiency may decrease in very cold conditions because the system must work harder to extract heat from the surrounding air.

Efficiency varies according to ambient temperature and operating conditions. The supplied system information states a COP of 4.30 at 15°C and 3.84 at 7°C.
It means the system delivers approximately four units of heat energy for every one unit of electricity consumed.
LBP Direct hot water heat pump systems are sold and installed through approved plumbers.
The heat pump unit includes a five-year warranty. Premium stainless-steel cylinders include an 18-year warranty, subject to regular maintenance conditions.
Regular maintenance is required to preserve system performance and meet applicable warranty conditions. The required schedule should be confirmed with the approved plumber and the product documentation.
