How to save electricity?

Busymom:
We have 5 + 2 maids... In March, PILs came for a week and I heard DH mumbling the bill for that month was $500-$600. Not sure if coincidence or not.
You have quite a few people at home right? Mine 5 of us including maid and it is usually $300+ at time even $400. How much is your bill now?Funz:
Have now decided to install a fan in every room and hopefully things will be better next year... although I doubt. :moneyflies:

Yah whenever my parents come over to stay, DH will be grumbling that the water bill especially will jump. Told him naturally, 2 more persons showering, drinking water. Hah. And because my parents are home the whole day we gotta cook a bit more during lunch. And since my parents are at my place, my sis will drop by for dinner more often also. So all these adds up. But conversely, electric bill will go down slightly as my parents will not turn on the aircon and kiddos will be bunking with us so only 1 aircon used at night. -

Heater is by gas, and ... actually i don't know much of it, come to think of it. It does take a while before water will turn warm after turning on the tap though... confirmed not instant heater, and I don't see a tank too.
Atrecord, how is your water heater system like? Those storage tank type or the instant water heater kind?
I reckon my storage water heater is eating up much of the electricity charges we pay each month. That tv too... (we used to have a 29\" tv but now we are having a 42\").
How about the washer? Top load or front load?
as for TV, if it was a CRT 29\" previously and it's now a 42\" LCD or LED, then chances are that it should be consuming significantly less electricity instead. At least that's the theory.
washer is top load. We got one of the few three-tick top load 9kg washer, but it's not a good choice, in my opinion. -
Imami:
The lower the temperature setting, the harder the aircon have to work, and the more power it consumes.
What happens when we set the airocn at 27-28 deg? Does it necessarily mean lower charges?
I have a friend who turn on one aircon every night. He said that there is a jump in electricity charges when the aircon is set at 25 deg vs 24deg (the jump is about $35).
Every 1 deg lower will consume about ~20% more electricity, IIRC, from PUB website. -

Really?? Then a difference of 5 deg C will mean doubling the electricity needed and costs required!

My fridge says freezer is -16 deg C. sure consume a lot of electricity... -
Whoa! I am really ashamed.... my monthly PUB bill is in the average of $1100 to $1500. Never below $1k.... no gas but with 8 units of sanitary appliance fee :lightrod:
I better repent before the next Earth Hours Day.

A fridge is not an aircon. You muz be kidding are you....?

1. A fridge cools a smaller volume of air, unlike the room. the volume can easily be perhaps >1000x different?
2. A fridge does not requires extensive piping to transfer cooling fluids around the place from fan coil to compressor. The journey itself results in inefficiency and energy wastage. This wastage is almost non-existent in fridge.
3. A fridge has insulated walls. I doubt your room have.
4. The fan coil in your aircon compare to the fridge..
5. You generate heat that the aircon needs to work very hard to get rid off.. For a fridge, there is not much living things inside it that will generate so much heat unless your food is decomposing inside or there are live mammals inside..
And others..
Lowering the temp setting in fridge of coz will also consume more electricity, but the impact will not be as great as for aircon due to the efficient design of the fridge insulation walls etc.. A few degrees difference wouldn't kill you.. Oops.. your wallet.. :evil: -
I forgot where I saw that 1 deg = ~20%… maybe wrong number…
Or maybe nowadays aircon more efficient… -

Hee hee i was not entirely joking. I read somewhere that the fridge is among the most electricity-consuming appliances at home, together with aircon (if you use it a lot), kettle, heater, etc. But of these, the fridge is guaranteed to be the most heavily-used, so it costs a lot to 'sustain' it.
The fridge also needs to cool to much lower temp cf aircon, so i'm sure it uses more electricity, although the aircon does need to cool a much larger volume. -
Depends on how you view it. For something that is switched on 24/7, I think it’s consumption is pretty decent.

yup, I agree with the above. When we were shopping for our appliances, hubby asked me I wanted how many ticks (for the appliances). I said four for all Aircons, fridges, washer and dryer. In the end, I only managed to get a four tick fridge due to space constrain. The washer and dryer are three ticks but the washer was said to be water efficient. We do away with a electric hot pot (those which maintain water at 90deg min) when ours died. I now have a kettle which I boil water everyday and store hot water in thermo flask.
