Most electric heaters create heat directly, using elements which heat up when an electric current passes through them.
These ‘direct element’ heaters include portable heaters, panel convectors and off-peak storage heaters. They have a maximum efficiency of 100%, when all the electricity is converted to heat and delivered to the room.
Reverse cycle air conditioning extracts heat from the outside air, even on mid-winter nights, and transfers it inside.
A refrigerant is passed through an external coil, absorbing heat from the outside air. This refrigerant is then pumped through a compressor into a fan coil unit (or ‘condenser’) inside the home, releasing its heat into the room.
Up to three or more units of heat can be transferred for every unit of electricity used to run reverse cycle air conditioning. Therefore, running costs can be as low as one-third of those for direct element heaters.
By reversing the flow of this refrigerant, reverse cycle air conditioners also provide efficient refrigerated cooling in summer.
What is its advantage?
- One of the most economical forms of heating
- Able to provide both heating and cooling
- Remain cool to touch at all times
- Have no exposed elements or flames reduce risk of fires, eliminate
risk of burning
- Lifetime of up to 20 years
- Filter and dehumidify air
