Compared to traditional heating methods, such as gas furnaces or electric heaters, heat pumps are generally more energy-efficient, cost-effective, and environmentally friendly. In this guide, we’ll cover what affects the cost, what you can expect to pay in 2026, and how long the process takes.

How Much Does It Cost to Install a Heat Pump in NZ?

Types of Heat Pumps

When considering a new heat pump for your home, it’s essential to understand the various types available and how each one operates.

Air source heat pumps
Are the most widely used type of heat pump in New Zealand homes. These systems work by extracting heat from the outdoor air and transferring it inside to provide efficient heating during winter, or reversing the process to cool your home in summer.

Ground-source heat pumps
Also known as geothermal heat pumps, operate by transferring heat from the ground through a network of underground pipes.

Water Source Heat Pumps
Water source heat pumps operate by transferring heat to or from a nearby water source, such as a lake, pond, or borehole. 

Hybrid Heat Pumps
Hybrid heat pumps combine the efficiency of an air source heat pump with the reliability of a gas or oil boiler. 

Ducted and Ductless Heat Pumps
Heat pumps can also be installed as ducted or ductless systems. Ducted heat pumps distribute warm or cool air throughout the home using ceiling or underfloor ducts, providing even comfort in every room.

Here are some of the main considerations:

  • Types of Heat Pumps: High-wall, floor console, and ducted systems all come at different price points. Ducted systems are the most expensive due to their complexity.
  • Brand and Energy Rating: Premium brands like Mitsubishi and Daikin offer higher efficiency, which may incur higher upfront costs but can result in lower power bills over time.
  • Size and Capacity: The larger the space, the more powerful your heat pump needs to be, which increases cost.
  • Installation Difficulty: Longer pipe runs, extra wiring, or limited access can increase labour time and costs, making the installation process more complex.
  • Electrical and Compliance Work: Some homes may require an electrical upgrade to meet safety standards, which can increase the overall cost of installing a heat pump.

Most standard systems take between 4 and 8 hours to complete. This includes mounting the indoor and outdoor units, connecting refrigerant lines, and testing the system. UR Plumbers’ professional plumbing services ensure the heat pump operates efficiently and achieves maximum efficiency.
