Turn geyser temperature down to 60o Celsius
Maintaining the temperature at 60oC uses less electricity (energy) than maintaining a temperature of 70oC. Works best when geyser and pipes are insulated. Don’t drop it below 60oC for health reasons. In most cases, the thermostat is located in the little cover over the electrical element of the geyser. Switch off the electricity circuit at the mains, undo the cover, and then turn down the thermostat using a screw driver. Or hire a plumber to help you (for safety reasons, make sure you tell those in the house that you are switching off the electricity for this purpose).
Reduce excessive heating or cooling
Space heating in winter is a big power ‘guzzler’, and the same for summer cooling for those homes with cooling systems. Use localised equipment rather than central air-conditioning or heating systems, and only heat or cool occupied rooms. The room temperature should not be more than 10 degrees (Celsius) more or less than the outside/ ambient temperature. Fan or oil heaters with thermostats are best, and avoid under-floor heating. In summer use a fan rather than air-conditioning. But rather than use equipment at all, the best ‘no cost’ saving options are things like wearing warmer clothing and using blankets in winter or opening the windows in summer.
Reduce pool pump operating hours
If you have a pool with a cleaning system pump, reduce its operating hours to the minimum e.g. 6 hours a day. Clean filters regularly, and consider a pool cover and turning off the pump at times in winter.
Switch off equipment when not in use
Turn appliances off at the wall plug, rather than leaving them on standby as this can still draw about 20% or more of normal electricity use. (Examples are TVs, music systems, computers, phone chargers etc.) Also turn the geyser off when you go on holiday.
Use less hot water
For example shower instead of bath, and take shorter showers. Only fill the kettle as much as you need it. Wash a full load of dishes, rather than one dish at a time. Use cold water where possible for laundry washing.
