Savings ? - The Quest for Zero Electricity

Many electrical appliancest need consideration when driving towards cutting the umbilical chord to Eskom.
 
Eskom claims these items pictured below are your major consumers of electricity,
which is why they target the Water Heating as a primary focus for their Demand Side Management program.

In 2 person flats or townhouses the electricity consumption can be as low as R300-R500 per month.
 
In these situations we find the geyser consumes a much higher proportion of the monthly bill than a "normal " 4 person household - in fact it can contribute 50-60% of the electricity cost.
 
Installation of a Solar Water Heating makes more sense because it will provide proportionally higher savings.
 

We invite you to join the Gorbi Mania and share the benefits achieved by our customers such as:
 
Installation 8th October:
Hi Alan, My electr bill all inclusive (water, levy elect) 
JULY R4003.12
AUG R4628.67
SEP R4090.62
OCT R2740.53
NOV R2368.13
Obviously the 1st 3 months were during winter - underfloor heating
Then Oct was much less - no u/floor heating plus beginning of my solar geyser
Nov i think could be a reflection of the solar savings .
 A R372 saving is not too shabby.
Regards

 Unit B
2 beds upstairs,
2 beds downstairs
typical occupancy of 1 person in each 2bed room
 
– geyser fed with pre-heated Solar Water
 
Average Saving >150kWh per month
Unit A
2 beds upstairs,
2 beds downstairs
typical occupancy of 1 person in each 2bed room
 
– geyser not connected to a Solar Water Heater
 
Average electricity Consumption is 2.3x more than Unit B consumes

Above is a recording of the electricity consumption of their geyser over a period of 2 months. Since implementation of solar in the second week of September one can see the geyser at this customer uses on average less than 2kWh of electricity per day, or as little as about R45 per month. This is achieved without any effort from the customer or compromise in the quality of their life.
 
With a little effort they could turn off the 1/2 hour automatic heating cycle every morning, and turn the geyser element on manually as and when its required, saving another R10-R30 per month.
 
Something to do in 2011 when the price of electricity will really cost plenty.

Joe has not connected the geyser element since installation of the Solar Water Heater last week.
 
Now thats Zero electricity !!
