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).
