The geyser is the highest consumer of electricity in the home (>3000 Watts)

• Set the temperature thermostat of the geyser to the recommended 60 degree Celsius.
• Install a timer that switches the geyser on and off according to the times you specify
• Switch off the geyser before you go away for two or more days.
• Buy a ‘geyser blanket’ from a hardware store
• (My recommendation) Replace the electrical geyser with solar geyser.
