Which electrical appliances are the most expensive to run

Household appliances such as pool pumps and heaters can quickly ramp up your power bill.

Pool pumps don't compare to resistive heating devices.

My pool pump is 0.75kw
Kettle is 3kw. Iron is 2kw. Hairdryer is 1kw. Oven when it was still electric was up to 6kw. Geyser 4kw.

But when on for 4hrs a day they are pretty expensive to run. But yes mine is also 0.75kw.

You should have added your mining rig in there for comparison.

Next time!

R1.42 /kWh isn't bad at all. Considering that we in ELN pay R1.98 for the same thing.

 

[LCBXX]

What needs to be factored in is data on the average hourly utilisation of the appliances over a day and then the graph becomes significantly more valuable.

That number for the fridge looks very low

If you want your pool to be maintained and look perdy, you are going to have to run that sucker a min of 8 hours p/d in summer. That's when a pool pump easily factors in the top 3 of chowing your electricity.

*edit*
Forgot to say, that the 8 hours is if you don't have a pool cover, of which a LOT of peeps still don't. Madness.

Doesn't an oven and stove count ? Would have expected them to be at the top of the list.

 

[WaxLyrical]

Useless graphic because we know Geysers, Stoves and Ovens are the most costly.

And who runs their toaster, kettle and microwave for an hour anyway?

Meh

Oh ffs, there goes my 4 hour toast making binges.

Hi everyone

Does anyone have information the electricity tariffs, why do different metros have different prices, are the tariffs regulated?

Thanks

 

[Gaz{M}]

Yes, all electricity tariffs are regulated by NERSA. You can view them on their website under Electricity - > Tariffs.

Each municipality has a different size, population, budget, infrastructure, maintenance, labour, free electricity allowance etc, so the costs are all different. That is why their tariffs are different. But the price they pay Eskom is the same. Municipalities also use electricity tariffs to generate their most profits, in order to subsidise other services (yes, it is crazy, but electricity is the easiest money to collect from residents).

For all these reasons, electricity is a cash cow and a way to force people to pay for municipal services. The increases each year are usually similar across muni's though, as NERSA tries to keep increases to a minimum.

What about the geyser, it takes 3000watts plus depending on the size.

The 3000 W geyser will cost you R4.26 an hour (3000 W * 1 hour * R1.42/kWh)

Normal usage like standing loss and say emptying it twice a day (150l geyser) will be more like the following:

Standing loss (100Wh per hour): 72 kWh a month

Normal usage:
Heating cycles: 2x 150 l (emptying is twice a day)
Element power: 17 ºC per hour water temperature increase
Inlet temperature: 15 ºC
Set temperature: 60 ºC
One heating duration: 60 ºC - 15ºC = 45 ºC --> 45 ºC / 17 ºC/hour = 2.6 hours

Energy = 3000 W * 2.6 hours/day * 2 = 15600 Wh = 15.6 kWh/day --> 468 kWh/month

Total monthly energy looks more like this: 468 kWh + 72 kWh = 540 kWh

Your realistic monthly geyser's electricity cost: 540 kWh * R1.42/kWh = R766.80

I'm not geysering right then. My monthly electric bill is only around R750...

 

[Not_original]

We have two geysers on the property , four people using one, two using the other, electric stove and oven and our monthly kw usage is about 800. Maybe the people in the house never baths. Yuck

heh.
I use 800kwh.

Gas for cooking, gas for heating, gas and solar for geyser, 3 people. Pool 4 hours a day.
I think your meter might be broken.

Emptying a 150 l geyser twice a day is no easy task. Its the same as taking around just over three baths a day (every day!) at around 44 ºC. It's probably not that you're not geysering right, you're just not excessively using hot water!
