How to Conserve Electricity when using Heating Appliances

In parts of South Africa, during winter, the heating of rooms is one of the largest sources of electricity consumption in a home.

Learn more on how you can save electricity when using heating appliances.


  • Infrared heaters are more electricity efficient than other space heating systems. These types of heaters can be used both for spot heating and area heating. They transfer energy directly by radiation, creating heat and comfort instantly without the use of air-circulation fans. An infrared heater will warm the people in the room rather than the space. Infra-red heaters often use metal-sheated infrared radiation elements, reflector lamps or quartz tubes.
  • The oil filled heater is the safest type of heater for the bedroom. A thermostat control switches the unit on and off as required, but to save energy, only use on the lowest comfortable setting.
  • Electric blankets consume little electricity. However, the correct method of use is to switch them on to the highest setting and warm the bed just before climbing in - then switch them off.
  • Close doors and windows when using a heater.


Insulate your ceiling
Improving a home's thermal insulation can save hundreds of Rands a year and improve the home's comfort.

  • Insulating the ceiling helps make a home a comfortable electricity efficient place. As much as 50% of heat losses in a house can be attributed to a lack of ceilings and ceiling insulation. If a home's ceiling is well insulated, heating and cooling expenses can be kept low. The effectiveness of ceiling insulation depends on the type of material from which it is made, its thickness and its density.
  • Ceiling insulation in SA varies from fibreglass insulation to a type of insulation prepared from a mixture of paper and other materials. The latter is blown into the ceiling, sealing the total roof area. Any of the methods are equally effective and the supplier of these insulation's will be able to offer reliable information about ceiling insulation.
