According to the experts, cooling and heating account for roughly one-third of the energy used in the average New Zealand home. There are multiple HVAC options to choose from, with some being more energy-efficient than others are. Energy efficient heating systems use less energy, save money, and help the environment by reducing harmful emissions. Heat pumps are an efficient way to use electricity to heat the home, and you can save up to $500 per year by choosing one over an electric heater. Before heat pump installation in Auckland, however, you should learn how they work.
How do Heat Pumps Work?
To keep its contents cold, a refrigerator transfers heat from the inside to the outside. A heat pump reverses the principle, transferring heat from the outside to the inside. Outside air is naturally heated by the sun, and solar energy is available even in the wintertime. Because Fujitsu heat pumps in Auckland only use power to move heat, they are very energy-efficient.
The Pros and Cons of Heat Pumps
Behind passive solar, heat pumps are one of the most energy-efficient home heating options. A heat pump is controlled by a thermostat so you can keep the home within a predefined temperature range. These pumps are available in multiple sizes ranging from ducted systems for the whole house to those that heat single rooms.
Theoretically, you can save a significant amount of money on heating by choosing a heat pump. However, in reality, many who use a Mitsubishi heatpump in Auckland end up keeping their homes warmer than they did before—so they get more comfort rather than a lower heating bill. While it can be tempting to use the heat pump for cooling in the summer, it can greatly increase power bills as the heat pump is not the most energy-efficient option for cooling the home.
Heat pumps are good for:
- Heating specific rooms
- Areas where air pollution is a problem
- Helping those who use electric heaters save money
- At less than 18 cents per kilowatt-hour, a heat pump is more efficient than an electric resistance heater.
- Most heat pumps are eligible for government subsidies.
- Heat pumps are controllable with thermostats and timers
- Some pumps use air filters to remove pollutants, which can be beneficial for asthma and allergy sufferers
- Heat pumps aren’t as efficient when the outside temperature drops below seven degrees Celsius
- They can be costly to install, especially in large homes that need ducted systems
- They can create a lot of noise for neighbours
- They must be installed by heat pump services in Auckland
- They are reliant on electrical power
- In some models, the refrigerant can be harmful if it leaks. The local council or landfill can provide tips on safe disposal.
Insulating the Home
The condition and level of insulation in your home will make a significant difference in how hard your Panasonic heatpump in Auckland must work to keep the place warm. Adequate insulation means that the home loses less heat through its doors, ceilings, windows, walls and floors. Less heat loss makes it less costly to heat the home properly, and it means that the house is more comfortable and healthier to live in.
Home Heat Loss
If the house is very draughty, insulation you install won’t do its job correctly. You should take steps to minimise the amount of air loss when improving the home’s insulation. Heat will always look for the shortest, easiest path out of the home. If you only insulate your ceiling, you cut the rate of heat loss from that part of the home, but you increase it in other areas.
For the best results, you should increase the level of insulation for every possible part of your home. The more insulated the home is, the closer a heat pump installation in Auckland will come to meeting your expectations. You can get ENERGYWISE funding for heat pumps and insulation.

All Heat Pumps are Unique
Many New Zealanders assume that all heat pumps have a high level of energy efficiency. However, differences in performance and operating cost can be substantial. On average, EnergyStar-qualified pumps cost about $150 less yearly to run than comparable, non-EnergyStar models.
The lowest-efficiency pumps sold in New Zealand have a 250% efficiency rating, which means they give off $2.50 in heat for every dollar spent on electricity. The highest-efficiency models are over 500% efficient, and the rate improves as new technologies become available to the public. Choosing an efficient model over a lower-efficiency one can make a substantial difference on your monthly power bill. Over a decade, the difference on a medium-sized heat pump can be $1500 or more.
Choosing a Heat Pump
Compared to other heating choices available in Auckland, a heat pump can represent a large upfront investment. However, it can be a worthwhile expenditure because, when sized and used correctly, a quality heat pump can keep the family warmer while helping you save on your power bill each month.
A quality brand from a reliable supplier should offer a minimum of a five-year warranty on labour and parts. Energy rating labels can help you make accurate comparisons between heat pump models. The more stars you see, the more efficient the pump is. Visit www.energyrating.gov.au to make an online comparison, and look for the blue EnergyStar mark when evaluating heat pumps.
