Hot water is the most energy hungry energy service in the typical home and is responsible for 39% of your monthly electricity bill. Here’s how you can start to optimise the savings.
Category 1 Savings
- Turn your geyser down to 60°C and be sure to switch it off before you leave for work. You only need to turn it back on again when you go to bed.
- Shower instead of bathing as you will use less hot water and hence less electricity.
- Use cold water if hot water is not necessary (for example, hand-washing).
- Try not to let hot water run unnecessarily. Get into the habit of using basin plugs when washing.
Category 2 Savings
- Insulate your water pipes and wrap your geyser in a geyser blanket.
- Reduce your hot water use even further by installing energy and water saving shower heads.
- Be sure to fix any leaking hot water taps as they can waste up to 18l of hot water a day which equates to lost energy too.
Category 3 Savings
- Install a Solar Water Heater which can be plumbed to add volume to your existing geysers or even replace them altogether. Solar water heating uses the sun’s energy to heat water.
- Alternatively install a Heat Pump, which can potentially cut your water heating costs by up to 67% compared to a regular geyser, depending on the variables of your situation.
- Optimise electricity efficiency even further by fitting your geysers as close as possible to the points where the hot water is actually being used.
