Signature WH30R Electric Water Heater, 30 Litres, 1500W, White

A compact tank for one bathroom

A 30 litre tank is a compact size. It generally suits a single bathroom, a couple or a small family, or a kitchen point where you want warm water for washing up rather than long back-to-back showers. If several people bathe in a row, a bigger tank gives more margin; if hot water is only needed at one tap, a smaller one is easier to keep warm.

What 1500W means on your electricity bill

The element is rated at 1500W, which works out to about 1.5 units (kWh) of electricity for every hour it runs. Your bill depends on how long the element is on each day, so heating once before the morning rush usually costs less than leaving it switched on all day. During load-shedding, remember that 1500W is a heavy load for most home UPS units, so check your inverter capacity before wiring it onto backup power. Use a properly earthed socket or dedicated circuit of suitable rating.
