How Heat Pumps Work


Heat pumps (or ‘reverse cycle air conditioners’) use the same technology as your refrigerator but in reverse, to heat your home. They work by taking heat from the air outside your house and transferring it inside, using a sophisticated compressor, fan and refrigerant gases.


The benefit of Reverse Cycle Heat Pumps

In New Zealand heating is the primary reason that people buy a heat pump. Virtually all heat pumps available in New Zealand are “reverse-cycle” which means they can be used for both heating and cooling which has undeniable benefits on hot summer days and nights. A heat pump in your bedroom can help you sleep more comfortably and you don’t have to run it all night – often just a few hours as you go to bed is enough to improve your sleep.

Most heat pumps also have a dehumidifying option as well to assist with condensation control.


Size and Location of Heat Pump

The size of heat pump you need is connected to the size of your room, the amount of windows and your local climate. Our home energy assessors can guide you on what size is best for your home and help with correct placement in a room to avoid draughts blowing directly onto you.

Energy Star Heat Pumps


EECA’s Energy Star is a programme which highlights the most energy efficient models available within a category. EECA estimates that the costs to run a heat pump will be $150 lower per year on an Energy Star heat pump compared to a non-Energy Star model.

Energy Star heat pumps are consequently more popular – for example in 2009/10 Energy Star heat pumps were 21% of the available models yet represented 65% of sales. Source: Energywise website

Installation of a Heat Pump

Installation of a heat pump involves two components: the indoor unit, which you see in all the ads and pictures, as well as an outdoor compressor unit. It’s important that both components of your heat pump are installed professionally as there are refrigerant gas and electrical considerations.
