How Much Does a Heat Pump / Air-conditioning Cost to Run in New Zealand?
Heat pump / Air-conditioning units are a popular heating and cooling solution in New Zealand due to their energy efficiency and ability to provide year-round climate control. If you’re considering a heat pump / Aircon for your home, one of the most common questions is how much it will cost to run. Let’s break it down by looking at the factors influencing running costs and typical energy usage in Kiwi homes.
Factors Affecting the Running Cost of a Heat Pump
Size of the Unit: The bigger the heat pump, the more energy it consumes. Ensure you choose a model that’s appropriately sized for your space. If you order in our online store, we will make sure that the unit you have ordered will suit the space in your home before installing the heat pump/ air-conditioning unit with quality materials in your home.
Energy Efficiency (COP Ratings): The efficiency of a heat pump is measured by its Coefficient of Performance (COP). A higher COP means more heating or cooling output for the same energy input.
Climate and Outside Temperatures: Heat pumps work harder in colder weather, so in colder regions like Dunedin or Invercargill, expect higher running costs compared to Auckland or Hamilton, Waikato.
Electricity Rates: The cost to run a heat pump depends on your electricity tariff. New Zealand’s average electricity rate hovers around $0.28 per kWh, but it can vary by provider and location.
Average Running Costs in New Zealand
Most households in New Zealand run their heat pumps for about 6 hours a day during winter. Based on information from various sources, here’s an estimate of how much it might cost:
- Per Hour: A typical heat pump (with a 3.5kW capacity) costs approximately $0.16 – $0.25 per hour to run.
- Daily Cost: Running it for 6 hours a day could cost around $0.96 – $1.50.
- Monthly Winter Usage: If you run your heat pump for 6 hours a day, every day for a month, the cost would be around $28.80 to $45.
These costs will vary depending on the efficiency of your heat pump, the set temperature, and your region’s electricity rates.
Tips to Reduce Heat Pump Running Costs
Set a Consistent Temperature: Setting your heat pump to around 18-20°C for heating ensures energy efficiency. Temperatures above 20°C can cause the unit to work harder, hence costing more power.
Regular Maintenance: Clean filters and maintain your heat pump / air-conditioning unit regularly to keep it running efficiently, saving you money in the long run.
Use a Timer: Program the heat pump to run only when needed, like just before you wake up or come home. Most heat pumps that are on offer includes Wi-Fi. Having Wi-Fi included in your heat pump system can make things easier. You can schedule and plan when you like your heat pump on or off.
Insulate Your Home: A well-insulated home retains heat better, reducing the amount of time your heat pump needs to run.
Comparing Heat Pumps to Other Heating Options
Heat pumps are one of the most cost-effective heating solutions in New Zealand. According to Consumer NZ, heat pumps cost between $0.10 to $0.30 per kWh to run, while electric heaters can cost upwards of $0.60 per kWh, and gas heaters between $0.15 and $0.40 per kWh
