When choosing the best air conditioner system to heat your home in Canberra, consider these important questions:
- What are the running costs?
- Do you want a ducted or non-ducted system?
- What is the purchase price?
- What are the installation costs?
- Is it electric or gas?
- Can the system cool and heat?
Heating systems running costs
The graph below from ACT Government compares the approximate costs of heating a large living area in Canberra to a comfortable temperature over a 12-month period, with some of the most common heating systems shown. This is a guide only. Your annual running costs will depend on your patterns of usage and may be very different.
As this graph illustrates, reverse-cycle air-conditioners (ACs) are the cheapest type of heating to run. These wall-mounted units, also known as split-system air conditioners, are around 300 to 600% efficient (check the model’s energy rating label for the number of stars). This is because they capture the energy that’s in the air and pump it into your home. This means for every 1 unit of electricity used they produce 3 to 6 units of heat.
Ducted or wall mounted Ducted Air Conditioning systems
Ducted or wall mounted Ducted heating systems also known as central heating, are designed to heat a whole house, with warm air blowing out of vents in the floor or ceiling. The heat can be generated by a gas furnace or by an electric reverse cycle air conditioner. A gas system may heat your home more quickly, but a reverse-cycle system will have much lower running costs (per unit of heat delivered) and can also cool your home for summer. Popular air conditioner brands to consider are Fujitsu, Daikin and Toshiba air conditioners.
Electric element heaters
Electric element heaters come in many types and sizes, including blower heaters, oil column heaters, bar radiators, and infrared panels. While they have different ways of emitting or distributing heat, the rate at which they convert electricity (efficiency) to heat is the same— about 100% (1 unit of electricity produces 1 unit of heat). This means a powerful heater might use 4 units of electricity and put out 4 units of heat. A low-power heater might use 1 unit of electricity and put out 1 unit of heat. Because electric element heaters have relatively high running costs (see graph) you should ideally only use them in small rooms, for short periods. If you’re going to use them for long periods, it might be more cost-effective to replace them with a split-system reverse-cycle air conditioner.
