Know This First: What is a Heat Pump?
In simple terms, a heat pump is a device whose sole purpose is to deliver heat where it is needed most, in this case, your home. To do this, the heat pump absorbs heat from an outdoor unit and then releases it into an indoor unit, also called the heat sink. As expected, in the process of transferring heat from one point to another, energy is consumed, which accounts for 80% of the operating cost of the device.
Types of Heat Pumps
If you google "types of heat pumps in New Zealand," you will find that most of the results talk about three types of pumps:
However, water-source and ground-source heat pumps are used almost exclusively in commercial and industrial applications. This leaves us with air-source heat pumps as the most common for domestic use. To further understand heatpumps, we explain the terms you'll read and hear when searching for heat pumps for sale in New Zealand:
- Air source heat pumps
- Water source heat pumps
- Ground (geothermal) heat pumps
However, water-source and ground-source heat pumps are used almost exclusively in commercial and industrial applications. This leaves us with air-source heat pumps as the most common for domestic use. To further understand heatpumps, we explain the terms you'll read and hear when searching for heat pumps for sale in New Zealand:
- Solar heat pumps. They are partially powered by solar energy to save on energy costs.
- Hybrid heat pumps. This kind of heat pump integrates a gas/oil heater to compensate for poor heat pump performance during cold weather conditions.
- Reversible heat pumps. The most popular type of heat pump since, like your car, it can function as both a heater and an air conditioner
- Ducted or packaged heat pumps. This kind of heat pump requires ductwork since all the components are located outside the house.
- Mini-split heat pumps. These units are indistinguishable from a split air conditioner. They consist of two components, the heat sink (indoor unit) and the absorption unit (outside unit).
- Multi-split heat pumps. They are a variation of split units. Their main difference is that they have multiple heat sinks so that you can install them in different parts of your home (bedrooms, living room, etc.)
Key Factors to Consider When Buying a Heat Pump in New Zealand
When choosing which heat pump is best for your family, consider the following factors:
- Capacity. The heat pump's capacity depends on multiple factors that include but are not limited to thermal insulation in your home, total area to be cooled/heated, ceiling height, room layout, and heat loads such as kitchen, TVs, lights, etc. Since this is a crucial factor, we recommend consulting an expert before making a decision.
- Defrost mode. When the ambient temperature drops below a certain level, it is common for heat pumps to freeze. That is why we strongly recommend choosing heat pumps with automatic defrost mode. Otherwise, you will have to shut down the pump to prevent freeze damage manually.
- Budget. Budget is always a deciding factor. That said, you don't often buy a heat pump, so we suggest favoring established New Zealand brands that offer specialist service. This will guarantee your investment in the long run.
- Area where you live. If you live in the lower South Island or inner Canterbury, you will be exposed to intense cold during winter, while if you live in the North Island, the climate will be more humid during the year. When choosing a heat pump, consider this aspect and prefer higher capacity pumps if you live in areas prone to colder temperatures.
- Type. Split or not split? Packaged heat pumps and their respective ductwork offer the advantage of lower noise levels and a more homogeneous distribution of heat/cold in your home. However, they are expensive units, challenging to install, and consume more energy than split units. On the other hand, split models are optimal for tiny homes that can be heated with one or two units. Finally, multi-split units balance cost and convenience for medium to large homes.
- Noise. Do not neglect this aspect, or you will regret it. Whether the heat sink is near your TV or in your bedroom, pay close attention to advertised noise levels.
- Energy consumption. This is another factor that should not be overlooked. Always favor units with higher efficiency, even if their initial cost is higher. In the long run, the money you save on electricity will be worth it.

Our View: The Fujitsu Multi System is a strong offering for anyone who doesn't want to invest in a costly central HVAC system and related ductwork. This setup consists of an outdoor unit that provides heating/cooling to multiple indoor units that are managed independently of each other. The most outstanding advantage of this approach is undoubtedly its versatility since you can control the temperature of each area of your home independently. Moreover, using a single outdoor unit saves energy compared to several independent mini-split units.
Another advantage of the Fujitsu Multi System is that you can use different models of indoor units. So, for example, you can use a cassette-type unit for the living room, a floor console in the kitchen, and a slim duct for the bedrooms if you wish. Hands down, this is the best option for large multi-level homes that value controlling the temperature of each zone independently.

What is a heat pump, and how does it work?
A heat pump is a system that uses electricity to transfer heat from one location to another. It absorbs heat from the air or ground outside and then transfers it inside to heat your home. Most homes in and around Auckland use them from April to October, but throughout the South Island they can be used to heat year-round.
