Using your air conditioner as a heater

18 Jul 2017

It’s quite amazing that many people who buy air conditioners don’t really think of them as heating devices, but rather as something designed purely to keep people cool in our hot African months. In this article we explore this myth and give you a few good reasons why you should be using your aircon as a heater.

Air conditioners are more energy efficient

We lose heat in our homes when we open windows and cool air blows in. Nature solves this in our bodies through the way our nose works. As kids we learn that it's better to breathe through your nose than through your mouth because your nose actually warms and filters incoming air. This is called ‘heat exchange’ because cool incoming air flows very close to warm outgoing air so heat energy is transferred between the two instead of being lost. This is how an air conditioner works. With its ventilation system you get fresh, warm air constantly circulating through the house. This is known as ‘heat recovery’ and for businesses and industry in particular, it makes the work place and factory floor far more efficient.

Air conditioners are more economic

Air conditioners then, as a result of this ‘heat recovery’, supply far more energy than they consume, which makes them the most efficient of all heating devices. In terms of cost efficiency, Aircons are up to 300% more cost effective than standard electric heaters and up to 1,000% more cost effective than gas or paraffin heaters! This could mean enough saving on energy bills in winter months to cover your summer energy bills when the Aircon is being used to cool you – something, by the way, that no other form of heater‘’ can do!

Air conditioners are better for the planet

The saving of energy (in particular the electricity we receive from the national grid which runs on dirty fossil fuels) is always a solid contribution to creating a cleaner, ‘Greener’ planet. So, by using your Aircon as a heater you’re not only saving money, but contributing to saving the planet!


The better the quality of the air conditioner - assuming it is regularly serviced and kept in good repair - the more efficient the heating aspect of the unit is likely to be.

Benefits of Inverter Air Conditioning

Inverter air conditioning is more expensive than non-inverter air conditioning, but with the deteriorating state of the energy system in South Africa, it is a worthy investment to consider.  The main difference is that an inverter air conditioning unit delivers a fixed amount of power using a fixed speed compressor. The speed of the compressor varies, so as to deliver the precise cooling or heating power required.

Benefits of inverter air conditioning

  • Up to 40% cheaper to run as it consumes less power
  • Reaches the desired temperature quicker
  • Startup time is reduced by 30%
  • Much quieter when running
  • No temperature fluctuations, therefor maximizing comfort level
  • No voltage peaks from the compressor
  • All Samsung inverter air conditioners are heat pumps which in itself is one of the most energy efficient form of heating.

How does inverter air conditioning work?

The amount of cooling or heating required by an air conditioner varies depending on the outdoor temperature and the amount of heat in the room. When cooling or heating capacity needs to be decreased, the compressor will operate at a high speed and will increase the amount of refrigerant flow.

When the inverter air conditioner is switched on, the compressor operates at a high speed in order to cool or heat the room quicker.
