Geysers are a major contributer to rising electricity costs, especially during winter when they lose more heat at a more rapid rate due to the lower air temperature.
Here are some tips to save Electricity and Money
Fit a geyser blanket or sleeve
Insulate all exposed hot water piping from the geyser with thermal pipe lagging, which will slow down and reduce the heat loss substantially.
In areas which experience frost, set the thermostat temperature to 65–70 degrees celcius. Otherwise set the thermostat to 60 degrees celcius, while in summer the temperature can be further reduced to 50–60 degrees celcius.
Regularly check your geyser’s thermostat and element for scale build-up. Excessive build-up may result in the temperature rising higher than that set at the thermostat.
Take short baths and showers. Taking a hot bath and topping up repeatedly with hot water increases energy consumption.
Bath and shower in the late afternoon or early evening.
When drawing a bath first fill with hot water, before adjusting with cold water. In winter an empty bath is colder, so hot water first into a cold bath will reduce the temperature.
Remember that showering uses much less water than taking a bath.
