    Then there is either something wrong with your thermostat or your geyser is leaking a lot of heat.

    Not me. I've tried it at two residences and at best it made no difference, at worst it might have been using slightly more.

    Then they should also say using hot water is bad for the geyser.

    You can also use a timer to maintain your geyser at some suitable low temperature. If for example allowing the temperature to drop below 25 degrees were harmful then you could set that as the target temperature during the 'off' period.

    Just try this out and see for yourself. We have a prepaid meter and after a week of turning our 2 geysers off during the day, we noticed almost no difference (if any) in our electricity consumption. You are only helping eskom.

    I can confirm that switching the geyser on and off on a daily basis will use significantly more electicity than just leaving it on. 10 units used in 3 hours just to heat from scratch, yet only 3 to 5 units to keep water heated for a day.

    My fiancee and her daughter are out of the house this week, so I've just turned mine off totally...

    A geyser should hold heat for like 3days.
    The basics apply to save money.
    Turn down the temp of the geyser.
    Get a better showerhead that uses less water, and shower.
    Make sure the geyser is properly insulated.
    Don't do silly things like run the hot tap in the kitchen for a minute just so you can wash your hands in warm water, you've just wasted all that heat on warming up the pipes all the way from your geyser
    Only bother with turning it off when going away for extended periods.

    Then again, what's the point of having warm water if I'm not going to use it?

    There must be a leak in your hot water outlet somewhere on the line. If the water in your area gets turned off for a period of time, when you open your hot tap does air come out?

    Same here. We use a lot more just to get the geyser reheated than getting it on.

    Also, if I need hot water, I don't want to wait for it. Earlier this week a friend got really sick and threw up on me while we were out on town. When I got home, reeking of vomit, I had to wait 45mins for the water to heat up so I could wash it off me. Let's just say my flatmate hasn't switched the geyser off again yet and leave it at that.

    That's got to be the best reason for leaving the geyser on!!!! Classic!

    It annoys me when people are indignant about these things. IF a geyser was meant to be turned off then they would install switches next to your shower.

    I highly doubt a geyser can withstand doing that day after day for a very long time.
    Why not leave your kettle on boil throughout the day? It turns off automatically right?

    Also I do not know about you guys but the kettle in my GF's house has now lasted 4-5 years without replacing the element... are geysers not suppose to be a tiny bit more durable than a R100 kettle?

    Does the average household's heater have to heat water to 100 degrees celsius? No.

    If you used all the water in your geyser so there was no warm water left after your household was done showering, then switching it off would make sense... otherwise not.
