What size hot water unit should I get?
The size of your hot water unit depends on a few factors. If you have a water-saving showerhead, the water consumption will be lower. In addition, it also depends on how long your average showers last. Also, your hot water unit should be enough to ensure that in peak use, the hot water stays on for all shower heads in the house. On average, if three water saving shower heads are on at the same time, 21Litres/minute will be used.
