Eskom's confounding average electricity consumption

Geyser switch doesn't make sense unless you're talking days, or trying to make it so it only switches on during solar.

Switching it on once a day is basically the same as just leaving it on as you're still trying to heat it above 55C / making up for the standing loss.

Sure, if it's you're going for a trip for a week, makes sense, and then heat it back up before use when you get back, but in general, no.

The granny flat geyser (2kW) turns on about 3 times (20 minutes x 3) a day if no taps are turned on.

2 person household plays a a role

Small kids don't impact load to badly , big ones do

So you kinda grow into heavy consumption

The same with cooking
For some it evolves

ie when your wife surpasses your mom/grandma

She makes an awesome sourdough bread lots of oven preheat for dutch oven and 40 min bake time

Big kids use even less power, they prefer to use tablets and phones vs TVs and other high usage devices, even if they have them

The savings is minimal , people do it , don't hit the same temp see a bigger saving and don't realise they aren't saving they are just compromising on temp/safety

I suppose it depends on gender and what they are into

Maybe because their dad understands PC's theirs aren't a gripe to use

Have only boys and their device usage are 95% pc focussed

My one kid is a quick shower guy

The other really enjoys his bath/shaving session cause when he is done the bathroom is as wet as a sauna , we joke that it takes hours sure feels like it

edit so funny that the onethat hates body hair is more prone to it the one that can't wait to grow beard the opposite genes
at that age you think you want hard beard

You said 3kw/h per day. If you only heat it when you want to use it it's only the heat up time. It then stays cold in any case till the next time so the loss is not a factor.

But as I said even if we include this figure for everyone it still doesn't reach 30kw/h for most people.

Gas. Our stove top doesn't even work any more so it's only the microwave being used for heating up and the oven I see only stays on for a few minutes before mostly switching off.

All depends on daily routines, geyser size, weather and consumption patterns

It depends on your usage patterns. If you heat it up afterwards then sure you're going to incur the loss in any case and just top it up the next time, but if you do it correctly and leave it cold afterwards there is no loss and the people I've seen doing it this way save between a quarter and half of their geyser usage.

yes you can save according to a quick google 1.3kwh a day so yea if you have extremely low usage this 1.3kwh loss can represent a higher percentage

so yea with maybe 2 bath sessions a day it would work out to a bit more than 10% loss of consumed
one bath session higher %
more bath sessions lower %

those that save that much probably are compromising on temp, sure you don't notice it since we mix with cold
ie the mix just has less cold water , the problem is though the lower tank temps opens you up to bacteria that is normally killed with a tank that is hot enough

by being a bit more aware keeping adco loperamides in the house simply isn't needed anymore
except if you get invited over to the old ( i'm old so should say older) peoples home for a meal

ie like xmas time or braai i dread it cause we always come of with an effect on the stomach
while you can go without any bouts like that inbetween
