many years ago I did the math. These controllers don’t save you much in fact; for the high end ones; you end up paying more. Switching off your geyser will make the water cold and to get the water to heat up again will cause you to use a lot of energy. I think the best solution could be to lower your geyser temperature; even slightly; like eliminate the need to mix your hot water with cold water.
 
Figures are thumb sucked. As not everyone's geyser runs the same time, the same kw and and. Though the load limiting does seem to work for Fourways
Using 220v Yea reducing your max from 13200w(60A) to 2200w(10A) will work but the geyser is at max 4000w(18A)

So yea their usage had to be reduced to the equivelant of 2.75 geysers each

ie they lost more than just a geyser during those times

So using that as an example of what we can do by all switching off geysers is stupid on a new level
 
As we've said before, you could cut more stages of load shedding if we turned everything off.
As whats also been said before..........so could the illegal connections. It's a touchy subject, much easier, more politically correct, less damage/ destruction and social unrest afterwards, for geysers to be switched off.....lmao

By moving all the geysers to a set time after peak we create a new peak , worse actually as we remove the random variable

If all geysers are off for a long period they are all going to switch on when they get power

ie so instead of 1-2 being ON

What ratio is then on?
2-4 or more?
 
Common sense would say

Just make the max geyser element allowed in SA 2KW

And you have skimmed a big chunk of the peak

Or make the max connection to homes 40A ie forcing people to manage/schedule the geyser or other high load devices to avoid trips

They don't want yo do this because once done and we still have load shedding this narrative is shown to be what it is bullshit

Switching geysers off over peak isn't the same thing as losing 50A capacity a geyser at max uses 16-18A

I live in Fourways. Yesterday I was pulling over 5kW from the grid during load-limiting. I'm not sure its working at all :whistling:
 
a lots of countries in asia uses gas heaters, maybe we can also going that direction in the areas already with the gas networks?

:eek:please don't ruin a good thing bragging about this, just quietly enjoy it like the rest of us while it lasts.
