Eskom's confounding average electricity consumption

Not sure what you're talking about, for a geyser you're heating up all the water in the tank to the temperature, that water will have a standing loss.

If you're talking about tankless, sure, I even have that, said so in the chat, but that's not going to 70C, that's still set to 45-50C (70C is very hot, you'd burn yourself without mixing in cold water), but a timer for on/off doesn't apply to this.

Not if you use it. It's cold afterwards so no standing loss. You're still thinking in terms of keeping it warm and not warming it when you need it.

Yea have to agree there will be a saving how much though is the question, you can save a portion of the 1.3kw rated loss over 24hrs

As the loss is less if temp is lower
But there will still be loss

Seldom is the geyser ambient temp after a bath it may feel that way to us what feels cold is way of from abient

Ambient overnight is often under 15
Pool temps in winter is often closer to that, so a cold geyser would feel like a pool in winter

A pool is a hell of a lot of water so it will be closer to the avg temp of night and day in winter hence why i say closer to overnight ambient

A cold shower is nowhere close to that

It depends on a number of factors, what the rating of the geyser is, how it's insulated/isolated, how long before use you switch it on, how much water you use.

The luxuries you mention make up a puny fraction of the "households" in this country.
So no, that 30kWh number sounds like utter BS... and since they don't want to release the numbers or their calculations we can all assume by default that it's BS.

South Africans just cannot seem to reach that point where they realise that certain institutions is made up of complete BS and the default position when dealing with them is in reality one of a UNIVERSE of BS. Eskom falls into this catagory. Folks try to rationalise the current lack of loadshedding in rational ways when that is a BIG mistake. There is BS and fu**ery afoot. It will only take a little while for it to become aparent where exactly it is...
 
I spend R2000 a month to buy 490 units for my box

Works out to 16.6 KwH a day

They are obviously including all industry in their figure, which is BS
 
It’s probably an average of actually paying houses. Also remember that would be summer through winter and most people do an easy 50% more oven winter.

Ironically my average which was around 30kWh before solar is now probably ably 45kWh.

Yes we are. People use gas because the power was always out.

Heat up 1 litre of water in the pot on your gas stove and 1 litre in an electric kettle, which one starts boiling first?

Rather get an induction stove if you really want to save costs as all that heat you feel on your gas stove is wasted energy.

Why are induction kettles not a thing yet?
 
Avg of 22-27kw a day.

2 geysers. One uses a heat pump
2 showers and 1-2 baths a day
2x PCs running 24/7
Multiple laptops
2 fridges
122 Led down lights in the house.
Electrical kettle probably Boils 10+ times a day.
Gas stove
Air fryer used daily for 10-20min
3x a week vacuuming and probably a total of 5-6 washing loads.

If the Jacuzzi is on, we use an extra 15-17kw a day

Household of 4, both the wife and me WFH.

Jirre that is one deeply inefficient jacuzzi.
 
everyone is load shedding will come back it wont we just gong charged the **** out of it for it

yea normally the jacuzi just use a plain old simple 4kw geyser eleement or multiples of

if using it regularly not from free excess solar , then the heatpump will probably ROI in 240 days/heating cycles of use

Indeed. In winter it needs to run for hours to get up to temp. It uses around 1600W when heating and only increases the temp by 1.5-2 degrees per hour on cold days.

bubble blanket or cover?
makes a difference


it probably uses a very small element
going a bigger element can also help as often the circulation pump uses 600w of that
so 4hrs of 1600w 1kw element + 600w pump

or 1 hour of 4600w 4kw element and 600w of pump

means a 29% saving

It has a cover. Jacuzzi is parked outside though, facing a valley which always gets a cool breeze from a nearby lagoon. Great in summer, freezing in winter.
 
Taking the stats captured by MyBB'rs in "Monthly Solar Production - Show us yours", which I deem to be FAR above average,
the daily average for all this year comes out to 29.66 kWh per day.

Eskom should go fly a kite in a thunderstorm
