- Choose an instantaneous water heater instead of a storage water heater as it is more energy efficient.
- Consider installing a solar water heater if you have access to roof space (e.g. living in landed property).
- If you are buying a storage water heater, a capacity of 23-27 litres is suitable for a family size of 4-6. Consider a storage water heater with a heat pump, which is more energy efficient as it absorbs heat from the room air to provide heat to water.
- The water heater should be placed as close to the shower point as possible so that less hot water is retained in the pipe and not wasted.
