YOUR GEYSER – LEAVE IT ON OR SWITCH IT OFF?

Does it really save electricity if you switch your geyser off?  And if so, how much is the savings and what is the effect it has on your geyser?

It turns out that the saving is about 2% on electricity, but that is not the main reason why Escom wants us to turn our geysers off.  They say:  “Geysers consume the most electricity in the home, so turning them off is effective when trying to control the peak demand and prevent load shedding.

The myths surrounding the question of “to turn off, or not to turn off” are myriad and some stories have even become urban legends.  We delved into the myths and pulled out the facts, so here they are for you, in a nutshell:

  • Your geyser is like a big kettle or urn. It has an element inside that heats the water up to a set temperature.  We would advise you to set up your geyser temperature at 55°C as on average, a lower temperature means a smaller consumption.   Under 55° you can have some bacteria that develop in your geyser. This can happen especially if there is a low water flow in your household.
  • Above 65° you increase the risk of calcification in you geyser and pipes. Also, if you have kids, you must remember that their skin is more sensitive and that they might get burn when they turn on the hot tap if the temperature setting is too high.
  • When you turn on a hot tap, hot water is released from the geyser and cold water rushes in to replace it. As the water temperature in the geyser has now decreased, the element kicks in to heat the water back up to the set temperature.
  • When no one is using hot water the temperature of the water should remain the same as no cold water is being let in. However, heat will “leak” out of the geyser into the surrounding area and the rate of the heat leak depends on the quality of your geyser’s insulation. These heat leaks cause the water temperature inside the geyser gradually to decrease and the element kicks in to reheat the water when necessary.

The factors that affect the energy consumption of your geyser are:

  • The type and condition of your geyser;
  • How much hot water you use; and
  • How often you use it.

So the best ways to help your geyser conserve energy are the following:

  • Only use the hot tap when necessary – washing hands, splashing your face etc. can be done with cold water only;
  • Use less hot water when you do use it – short showers or shallow baths rather than long showers and deep baths;
  • Turn your geyser off when going away for a few days – then it makes it worth it;
  • Ensure your geyser and water pipes are properly insulated – ensuring that heat leak is lessened.

So there you have it:  turning your geyser off will not necessarily save you money, but if you turn it off during peak periods, you can help to prevent the inconvenience of load shedding.
