Is it worth switching your geyser on and off to save electricity? What’s the best way to save money on your bill? We bust a few geyser myths…
Let’s start busting a few geyser myths by first giving a simplified explanation about how an electrical geyser works. The water in the geyser is heated by an electrical element (a thermostat) to a particular temperature (which you set manually).
If the water temperature ever drops below this set temp, the geyser automatically switches on and heats it up again. In other words, it works like a large kettle that continuously heats its water.
Does turning your geyser off save electricity?
Unfortunately the answer depends on how frequently you use your geyser and how often you empty it.
The argument for switching off your geyser:
- By switching off the geyser you eliminate the possibility of the thermostat constantly drawing electricity to heat itself.
The argument against switching off your geyser:
- Once you turn the geyser back on (after a day of being off) it needs to heat itself from a far lower temperature, therefore it uses as much (if not more) electricity to heat it up again.
So how should I save money on my geyser?
The amount you spend on your electricity bill has more to do with what kind of a geyser you have and your frequency of use. The better the quality of the product and its insulation, the longer the water in your geyser will stay hot for.
Secondly, if a lot of people are using one geyser, more hot water is going to be used, which means more cold water is going to have to be heated by the thermostat. This will use more energy.
So essentially if you have a modern geyser and piping with great insulation that maintains its set temperature without having to reheat itself throughout the day (unless they are being emptied frequently), you will save money on your bill.
So before you switch your geyser on and off, try this:
- Test whether your geyser uses more or less electricity when you turn it off and on every day. Try for a week and compare your usage, then decide what you’re going to do.
- Turn off your geyser when you’re going away for a weekend or holiday.
- Use less water in general (hot and cold).
- Invest in a well-insulated geyser and insulate your pipes.
- Consider using a renewable energy source such as a solar power geyser as opposed to electrical heating systems.
