Heat pumps are one of the most efficient types of home heating, but some people find them ineffective or may even incur higher power bills because they don’t understand how to use them effectively. Understanding the different settings and how to programme them is crucial. This fact sheet explains how.

Winter Heating














1. Press MODE or MASTER CONTROL button until you have selected the Heat (Sun) setting.














2. Press the FAN button until you have selected the Auto Fan setting.














3. Set the temperature between 20OC and 22OC. Setting the temperature higher makes it work harder and it will be less efficient.
Running a heat pump at 26OC will use 50% more power than at 21OC.
If you are not at home during the day, turn the heat pump off when you go out.














4. Use the SWING button to adjust the direction of the air flow down into the room (refer also to next page).


Heating Cycle

Watch the vertical flap movement; press the SWING button to stop the flap at the position of your choice.







High wall mounted heat pump   Floor mounted heat pump

For heating, direct the warm air down across the floor where it will rise up, warming the room.
(If cooling in summer, direct the cold air high across the room, where it will sink down, cooling the room).


Maintaining your heat pump

Clean the filters monthly, or every two weeks if using it a lot.







Frequently asked questions:

Sometimes cold air comes from the heat pump – what can we do?
• First check the fan setting
• If the fan is on low or quiet setting, you will only get about 1/4 of the heat the heat pump is capable of delivering.
• Make sure the Fan setting is on “Auto” or “high”.
• Check that the Mode setting is on the “Heat” setting.
• If the outside temperatures are very low sometimes the heat pump will go into defrost mode.
• Try using the timer to turn on the heat pump in the morning before you get up, or leave the heat pump on 16oC overnight.

How much does it cost to run a heat pump?
• A 6 kW heat pump running for 8 hours a day will add around $60 to $70 a month to your power bill.
• That is based on running it in the correct settings.
