Heat Pumps

Featuring the best heat pumps in New Zealand

In New Zealand, heat pumps are a popular choice for heating and cooling homes thanks to their efficiency, low operating costs, and ease of installation. When selecting the best heat pump for your needs, several key factors should be considered, including the type, capacity, defrost mode, budget, and the specific requirements of your home environment. Only the best heat pumps in New Zealand are featured on ArchiPro, an important part of a broader range of heating and cooling solutions that you consider for your home.

Types of heat pumps

Air to air heat pumps

As the name implies, air-source models transmit external heat to a building's interior. Most models are reversible and capable of both air heating and cooling, using vapour compression or hot water.

Ductless air pump

Also known as a ductless mini-split heat pump, this model is designed for use in buildings that have no ducts, mostly those formerly using radiators or various hot water heaters or radiators.

Exhaust air heat pump

Some ducted systems use the exhaust from a building to maximise the effects of evaporation to the condensation method. In general, they are energy-efficient and more cost-effective in the long run than other systems. They are also considered healthy due to the fact that no burning and carbon emissions are involved in the process. 

Vapour compression based models

These models work similarly to air-conditioners or refrigerators. The delivery unit is placed indoors and connected through pipes to the outdoor system. 

Reverse cycle chillers

This unit uses water instead of a vaporised refrigerant. Heated water is then travelling through internal radiator systems.

Underground heat pumps

This type of pump uses the advantages of more stable in-depth temperatures to operate more efficiently. Some models use a dual-line system, with two pipelines connected to the exchange box. One line runs between the source and the exchange box, while the other attaches it to the indoor unit. 

Underwater heat pumps

Designed to use the benefits of deep water sources proximity, water-based heat pumps employ them as a medium for heat exchange. Many versions also use refrigerant, turning water into gas and then back into the water again. Due to the relatively stable temperatures at the source, underwater heat pumps can be efficiently used in more extreme climates. 

Hybrid heat pumps

Most conventional types face the challenge of efficiently providing necessary heat levels in very cold climates, often requiring costly support systems during extreme cold seasons. Hybrid heat pumps get around this using alternative power sources, such as gas-fired or solar-powered heat pumps. Gas-fired models use natural gas as their power source and can sometimes function as coolers, while solar-powered models harness sunlight directly or through solar panels to provide reliable heating.

Heat pump elements

Condenser

The segment that turns gas into a liquid. 

Evaporator

Reverses the condensation process by turning liquid back to gas, making the material absorb heat from the surroundings.

Expansion valve

Designed to control the flow of supplies injected into the evaporator.

Compressor

Controls the amount of refrigerant flowing through the system.

Refrigerant

The gas/liquid moving through the system.

Ongoing maintenance requirements

Proper maintenance is essential for the optimal functioning of all heating pump systems, including regular cleaning of filters and fans, periodic cleaning of outdoor coils, and following manufacturer-recommended maintenance tasks. Additionally, clearing surrounding areas of debris helps ensure efficient operation. Professional services are also available for comprehensive semi-annual and annual maintenance checks.

Things to consider before buying heat pumps

When buying a heat pump in New Zealand, consider the climate of your specific region, as different areas experience varying temperature ranges and weather conditions. Evaluate the energy efficiency rating to ensure lower operating costs and better performance. The size and layout of your home are crucial in determining the appropriate heat pump capacity needed for effective heating and cooling. Look for intelligent controls, quiet operation, and air purification to enhance comfort and convenience. Additionally, check the reputation and reliability of the brand and installer, and consider warranty and after-sales service for long-term support.

Other heating and cooling solutions to consider

There are more than just heat pumps to consider for your heating and cooling solutions. For example, fireplaces are a heating method that dates back to ancient times. However, cooling is also an important element when improving your home. Installing high-quality fans will keep your place from feeling too warm.
