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.

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.

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.

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?
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.
