By covering the geyser with a geyser blanket and insulation the hot and cold water pipes, the standing losses can be reduced by up to 27% or R240.00 per year (at 50c/kWh).

Aerated Shower Heads

Aerated shower heads can reduce your shower water usage by up to 50%, Therefore, less hot water would be used, thereby reducing the power requirements of your geyser. These shower heads are both water-saving and energy-reducing devices. Both of these benefits are achieved without compromising on comfort.

Heat Pump Water Heaters

Heat pumps can save up to 70% of the electricity used to heat water to the equivalent heat in a normal geyser. In a typical household in which 30 to 50% of the electricity used is spent heating water; that represents a reduction in the electricity bill of up to 21 to 35%. A heat pump is a device which absorbs heat from the air outside your home and transfers that heat to a heat exchanger that warms water inside the house. It looks like an air-conditioning unit and can be installed on the outside wall in close proximity to the geyser. For residential customers, Eskom is now offering rebates for replacing an existing electrical geyser to a heat pump.

Solar Water Heaters

Installing a solar water heater at home can reduce the costs of heating water by up to 70%. Eskom's Solar Water Heating Programme is structured around an incentive scheme which reduces the selling price of a solar water heating system. This incentive is subject to specific conditions.

Variable refrigerant flow (VRF) air-conditioning systems can reduce energy consumption by 35%. VRF systems are not new to the air conditioning market. However, due to their energy saving, space saving, and aesthetic qualities they have rapidly gained popularity. VRF air-conditioning systems can be made up of several air handling units (AHU), all of which are connected to a single external condensing unit. The system operates through the use of inverter technology, which relies on variable controlled compressors and fan motors.

Smart Meters

A smart meter generally refers to a type of advanced meter that identifies consumption in more detail than a conventional meter and optionally communicates that information via some network back to the local utility for monitoring and billing purposes.

Benefits of Smart Meters:

  • Provides users with the ability to view real-time electricity consumption through a home or office computer.
  • Has a home automation facility which allows the user to set timing controls to certain circuits (pool pump, geyser, lighting, etc…).
  • Case studies have revealed a significant drop in electricity usage when used together with other initiatives.
