Doing Eskom a favour

17 May 2013, 08:42


 After my recent clash with a power saving scam I was left thinking about a electrical saving scheme which will cost the user very little and gain a substantial savings in electrical energy.

One of the largest users of electricity in most residences is the Geyser. The geyser remains switched on the full period of its use and that means 24 hours a day. It does have a thermostat which switches it off when the set temperature is reached. The geyser will lose some heat while the temperature is dropping and on reaching the preset temperature the thermostat will operate and switch the element back on again and so the cycle will continue indefinitely.  After the family has bathed and supper is past the hot water temperature will be lower than normal. At say 7pm the geyser is manually switched off and remains off for the duration of the night. The geyser is switched back on again at about  5am.  In my own case and geyser size it takes about 2 hours to attain a working temperature.  After the scramble for breakfast and a wash and other activities the geyser is switched off by the last adult leaving the house to go to work.   Depending on the working hours the temperature may drop even more and when late afternoon is reached then the geyser must be switched on again.  While this is practical and such is my case  It is obviously easier to install a multi position timer and relay to automatically operate the geyser and switching at preset times to give optimal switching of the element.  Note that some variation may take place due to different element wattages.

According to the time setup as given above it will be seen that the geyser is “on” for only 4 hours throughout its daily cycle and 20 hours “off’  per centage wise then the geyser will be on for only 16,6666%  while total off time would be 83, 3333 %.  Further, it must be remembered that the thermostat is working throughout the on cycle and will still switch off the power when the water reaches its pre-set maximum temperature.

Alternatively the relay/timer/ circuit breaker will work just as well and even better than the manual operation as set out above but there may be higher additional costs concerned but will have to be passed by the authorities such as the SABS.
