Here is an energy saving tip from the TEAM at De Aar Solar Power. Consider the benefits of installing a geyser timer to save on energy costs. It’s a simple device that controls the time that your geyser comes on and switches off. With the geyser permanently on, every time the water temperature in the geyser falls below the set temp, it will switch on to return the temperature back to where it needs to be.
So, first thing in the morning if hot water is required and then at night for showers and baths. Once everyone is done, the timer can be set to switch the geyser off and only back on again the next morning, so it doesn’t run all night.
