Timers

A device may be used to switch the electrical supply on and off at predetermined times over a 24-hour period. A commonly used timer is for the pool pump set at certain intervals to switch the pump on and off. With the need to conserve energy, a timer installed for geysers is now commonplace. Heating water in a geyser only at certain times during the day saves a lot of energy.
