Heat Pumps

Why choose a Heat Pump?

A heat pump offers the best of both worlds, giving both heating and cooling comfort for your home, all year around.

  • Most efficient way of using electricity to heat/cool your home.
  • Heating and cooling at the push of a button.
  • Programmeable heating/cooling.
  • Hi wall, ceiling, floor console and ducted options.

While heat pumps are the most efficient way of using electricity to heat your home, some are more efficient than others.

Use the energy rating label to compare heat pumps.

All heat pumps have an energy rating label which helps you compare the efficiency of similar sized models. The more stars, the more energy efficient a unit is. The red stars are for heating efficiency and the blue stars are for cooling efficiency.

Our most popular Fujitsu and Hitachi heat pump models are on the Energywise Recommended Heat Pumps List.

Understanding the numbers

A heat pump label dislays numbers that can tell you more about the heat pump's performance.

  • Capacity output - the amount of heating or cooling (kW) you will get out of the heat pump (tested at 7˚C). Eg 6kW

  • Power input - the amount of electricity the product uses (kW) to produce the cool or hot air. Eg 1.42kW

  • Coefficient of Performance (COP) - is the ratio between the heating power input and capacity output.
  • Energy Efficiency Ratio (EER) - the ratio between the cooling input and output.

You can use these numbers to calculate a heat pump's efficiency. The higher the ratio(COP or EER), the more efficient it is.

For example our Fujitsu ASTG18KMCA model

         Capacity output      6kW

         Power input            1.42kW

         COP                       4.22

For example our Hitachi RAS-E50WHA model

         Capacity output      5kW

         Power input            1.42kW

         EER                       3.52 

Tips for using a heat pump efficiently

Like any heating option, heat pumps give the best energy savings when they are used smartly. You can save hundreds of dollars on your power bill a year with a few simple actions:

  • Only heat the space you are actually using, shutting doors and curtains to keep the heat in.

  • Set the remote control to a healthy temperature.  Aim for a minimum of:

    • 18ºC while you are using a space.
    • 20ºC if you have children, are elderly or if there are unwell people in the home).
    • 16ºC in bedrooms overnight.
    • Do not set to an unrealistic temperature as it will not achieve it eg 25ºC.
  • Learn to use the timer features. Do not leave your heat pump on all day if you are not there. You can set the unit to turn on half an hour or so before you get home.

  • Maintain inside unit (as per manufacturer's instructions):

    • Clean exterior of unit first.
    • Clean the indoor unit filter regularly, for example change of seasons. 
  • Maintain outside unit:
    • Turn the power off to outside unit and wash the rear and outside of the unit.
    • Keep clear of debris and foliage.
    • Spray outside unit to deter insects nesting eg ants and cockroaches.
  • Be aware that it costs more to run a heat pump in cooling mode than heating mode.

  • Air Direction Lourves:
    • Cooling mode - best to aim lourves across the ceiling.
    • Heating mode- best to aim lourves down.
  • On cool Winter mornings ice may form on the outdoor unit coils, the heat pump may go into Defrost Mode automatically, where heat is used to melt the ice instead of heating the room.  Some indoor units will display a light indicating Defrost Mode.  Avoid touching settings in this mode as it may last 10-15 minutes and may happen on more than one occasion depending on how cool it is outside.

For trouble free use set your heat pump for the season.  
In Summer set the mode to Cool (Snowflake icon) and in Winter set to Heat (Sun icon).  

The fan should always
be on Auto or (A)..
