Load Control Unit (Relay or Timer)

The cheap, quick & easy way to regulate electricity

If you are using a standard geyser (hot water tank) to supply hot water needs to your building, then consider installing a Relay Timer. It is a cheap, quick and easy way to regulate the amount of electricity directed to your building hot water tank or geyser. The device allows your hot water tank to operate more efficiently by turning it off during the periods of the day or weekends when hot water is not required and then switching it on for peak hot water demand periods.

A relay timer or load control unit as it is sometimes called can be customised according to your own building needs by simple programming. There are devices available on the market that can regulate multiple hot water tanks from a remote location. See the Green Building Africa Special Offers.
