The Cost of Heat Pump Installation in New Zealand: What Homeowners Need to Know

Man thinking of heat pump and installation cost

While heat pumps are the most popular form of heating in  NZ because they are normally the cheapest to run compared to other heaters, they are not the cheapest heaters to buy or install. While their purchase price is relatively similar no matter where you buy it from, the cost of installation  can vary widely, and there may be ways to reduce this. Here are the top five tips to reduce your heat pump installation cost.


Since 2015, OneAir has provided New Zealand homeowners with heating solutions that meet their individual needs. During this time we have  developed a good understanding of what the most common questions people have and also what the most common misconceptions are as well. This comprehensive guide will break down the factors that influence heat pump installation costs in New Zealand, explore the different types of systems available, and provide tips on how you can save money choosing the best solution for your home.


Understanding the Basics of Heat Pumps

Before diving into costs, let's clarify what a heat pump is. Essentially, it's a device that transfers heat from one place to another. In the context of homes, it extracts heat from the outside air (even in winter) and transfers it indoors, providing warmth. Conversely, it can also remove heat and humidity from your home during summer, when in air conditioning mode.


Factors Affecting Heat Pump Installation Cost

The cost of installing a heat pump varies significantly. Heat pump installation costs in New Zealand typically range from $1,500 to $6,000, depending on several factors:

  • Type of Heat Pump: The type of system you choose significantly impacts the overall cost. Aside from portable or window-mounted units, all-mounted units are generally the most affordable, starting at around $1,800 including installation. On the other hand, ducted heat pump systems, which provide heating and cooling throughout the entire home, are usually the most expensive, with costs starting from around $6,000. One thing we’ve learned that many people are surprised by is that even though multi split systems only have one outdoor unit instead of one for each indoor unit, they  are still more expensive than equivalent standard, single split models. This is because multi split outdoor units are very complex, and require special materials and manufacturing processes to cram everything into just one outdoor unit.

  • Size of the Heat Pump: Smaller heat pumps cost less than large ones - while the cost difference is a few hundred dollars in the smaller ranges (2.5, 3.5 and 5kW) the costs increase significantly more in the 8kW and 10kW sizes.  Because the capacity of a heat pump required depends on the size and more accurately, the air volume of the room or area you want to heat or cool, rooms with high, vaulted ceilings need larger heat pump systems than standard-sized rooms. Other factors influencing heat pump size are how airtight the room is, how well insulated it is and how much sun that enters through the windows. For example, a more extensive ducted system may be necessary to ensure that a multi-level home is adequately heated or cooled, so if you want to save money on heating.

  • Installation Complexity: Factors like wall construction, electrical wiring, and the distance between the outdoor and indoor units can influence installation time and cost. The ease or difficulty of the installation process can also affect costs. Homes with unique layouts or older properties may require additional work to accommodate the heat pump system, leading to higher costs.

  • Brand and Model: As with any product, heat pump brands and models vary in price. Higher-end units with advanced features will typically cost more.

  • Labor Costs: The labor cost can vary depending on the region, the installer's experience, and the complexity of the installation.

  • Location: Installation costs can also vary based on your location in New Zealand. In areas with higher demand or limited competition, prices may be higher. Additionally, material and labor costs may fluctuate based on the region, impacting the total installation expense.


Types of Heat Pump Systems Available in New Zealand

Understanding the different types of heat pump systems can help you choose the best option for your home. The most common types include:

  • Highwall Heat Pumps: These are New Zealand homes' most popular and cost-effective options. Mounted on the wall, these units are easy to install and are ideal for smaller spaces or individual rooms. Prices start at around $1,500.

  • Ducted Heat Pumps: Ducted systems are more comprehensive, providing heating and cooling throughout the entire home via a network of ducts. While these systems offer greater control and efficiency, they come at a higher cost, with installations typically starting around $6,000.

  • Floor-Mounted Heat Pumps: These units are installed close to the floor and are ideal for homes with limited wall space. They are often chosen for their discreet appearance and efficient performance.

  • Ceiling Cassette Heat Pumps: Installed in the ceiling, these units are perfect for homes with premium wall space. They are more expensive than high-wall units but provide even air distribution throughout the room.

Regional Differences in Heat Pump Costs

The cost of installing a heat pump can vary significantly across different regions in New Zealand. Factors such as competition among installers, local material costs, and even the climate can influence prices. For example, areas with higher heating demands during winter might experience slightly higher installation costs due to the need for more powerful units.

New Zealand's diverse climate, ranging from subtropical in the north to temperate in the south, plays a role in the demand for heat pumps and their installation costs. In warmer regions, homeowners may prioritize cooling capabilities, while those in colder areas might focus on heating efficiency. This demand influences the availability and pricing of heat pumps in different parts of the country.


In addition, local material costs and the level of competition among HVAC contractors can vary by region, further affecting installation prices. For example, competitive pricing might drive costs down in areas with a higher concentration of HVAC contractors, while in more remote areas, limited options could lead to higher prices.


Government Incentives for Heat Pump Installation

The New Zealand government offers various incentives and rebates for heat pump installations to encourage homeowners to adopt energy-efficient solutions. These can significantly reduce the upfront cost of your project. You must check with your local council or energy provider for the latest information on available incentives, as they can change.


Managing Budget Constraints: Tips for Affordable Heat Pump Installation

Budget constraints are a significant concern for many homeowners when considering heat pump installation. Here are some tips to help you get the best value for your money:

  • Stay Grounded: Outdoor units can be mounted on wall brackets and even on the roof. While this may save space, it adds significant costs so to keep costs to a minimum, make sure your outdoor unit is mounted on the ground

  • Short is sweet : Try to find a location for the outdoor unit as Aim for the shortest-possible distance between your indoor and outdoor units:

  • Push for promotions: the heat pump market in NZ is very competitive and the distributors often run promotions to increase their sales. One example is Mitsubishi Heavy Industries’ Cashback promotion which provides payments of up to $500 to customers installing a heat pump. These contests typically do not run all year round, so ask your installer to contact several suppliers and find out what brands are running promotions

  • Choose the Right System for Your Home: Work with a reputable HVAC contractor who can assess your home's specific needs and recommend the most efficient and cost-effective system. Avoid overspending on a system that's too powerful for your space.

  • Consider Energy Efficiency: While more efficient systems often have a higher upfront cost, they often result in lower energy bills over time, leading to long-term savings. Look for heat pumps with high energy efficiency ratings.

  • Take Advantage of Financing Options: Many HVAC installers offer financing plans that allow you to spread the installation cost over time. This can make it easier to manage the upfront expense.


Long-Term Cost Benefits of Heat Pumps

While the initial investment in a heat pump might seem significant, it's essential to consider the long-term cost benefits. Heat pumps are highly energy-efficient, which can significantly reduce your heating and cooling bills compared to traditional gas or electric heaters. Additionally, improved indoor air quality can lead to health benefits for you and your family..


Choosing the Right Heat Pump Installer

Selecting a qualified and experienced installer is crucial to ensure your heat pump's optimal performance and longevity. Look for installers with certifications and at least 200 Google  reviews as it shows they have experience and have been around for a while - important if you want them to help if you have problems later on. Like anything that requires a significant spend, It's also advisable to obtain multiple quotes from different installers to compare prices and assess their standard of customer service.


Choosing a contractor that offers an end-to-end solution can also provide significant value. From selecting the right system to professional installation and after-sales support, a full-service HVAC provider ensures that your heat pump operates efficiently and lasts for years (10-15 is not uncommon for good brands that are well maintained).
