fair enough. you have a point here. will try your suggestion to keep it off unless for bathing purposes. for minor stuff like washing hands nor mal pressure would suffice.

your tnb rate is better than mine considering the number and type of appliances you have. my air conds which I use consistently are inverters and I only have 1 water pump and I only use the hot water storage sparingly. and even then, I use a ceiling fan to circulate the air in the bed rooms which I switch on the inverter airconds.
will keep in mind on the usage of downlights and yeah, you are right, 1 switch connects to a few, in my case, 1 switch connects to 2 downlights.
as for the maid, as far as I know, she does not switch on the aircond, but I could be wrong.
will also start switching off the water pump unless it is for bathing purposes.
Don't have a pc in the house. heheh..IT illiterate.

same here. I think the biggest culprit is the aircond. I am trying to figure out how to manage it.
the dryer not so bad not since I am on landed property so usage have cut down by 90%.
Fridge only 1 700+ liter fridge. but inverter tech.
I will have to monitor my meter lah like this.

you have a point here. but the thing is, the air conditioners are only switched on at night from 10pm onwards, I doubt whether the heat from the sun could result in the room being difficult to cool down at 10pm at night. but I could be wrong.

Only two rooms occupied plus maid's room which pasang kipas only.
the 2 rooms I just reset the settings to 26c with lowest fan.
I also decided to switch off the water pump at night and only use it during the day.
whatever appliances which is plugged but not in use I have unplugged.

now I am keeping a log on my usage. I took my tnb meter reading yesterday at 7pm and this morning at 7am. later today will check again reading at 7pm. will do this a few days to have a rough estimate of my usage, then see how or what to cut down.

I am also going to keep a log on usage of deep fryer and oven. just for comparison.

normal island and peninsular house. I went up to the roof when we did the renovations, no insulation. at that time, no budget for insulation cause of costs overrun and lousy contractors who messed up stuff.

only my bathrooms and kitchen has the ventilation fan. did not think to put it anywhere else.

for ventilation, normally what we do is keep the fan on for a short while and open the windows to circulate the air. its not effective but no other way unless I spend big to do ventilation fans and insulation.

same billy...my first month bill 586, my second month bill 700 plus.

would there be any difference between a three phase unit and a single phase unit?
Would this have any effect on the bill even though the electrical items used are pretty much the same?

what is an e bill and what is a n bill?

thanks for the explanation.

yup, was also worried about the maid, hence the reason why yesterday, I went back home and switched off all the air conditioners via remote and brought it upstairs to my room. at least I now know that the air conditioners down stairs will not be used without my knowledge. I also advised the maid to switch off all unnecessary lights (1 light switch controls 2 18 watt LED downlights) when not in use. this morning, before coming to work, the downstairs was pitch dark. good to know she actually listens to me.

She doesn't know how to use the oven, so I am safe there, anyhow, I unplugged it last night.

She does use the deep fryer and microwave. but we don't deep fry much or for any length of time.

we don't have any cctv yet, but wiring all done.

no pc also. IT illiterate.

vacuum cleaner is a 2800 watt Electrolux. used once in two days to vacuum all the carpets in the house. total time for vacuuming is +/- 2 90 minutes.

Right now I think, my biggest electricity culprit are the air conditioners and the storage water heater.

I made a list of all the big ticket items at home and made a mental note to keep track of the usage of these things.

air-conditioners
storage water heater
water pump
deep fryer
clothes dryer
oven
electric kettle

did I miss out on any other big ticket items?

noted on the fridge. we have a 700 plus liter fridge. this cant do much cause will still open and close only when to take stuff out or put stuff in. we have only 1 fridge by the way.

only rm90!!!
wow!!
I have no idea why it can be so much.
but I am taking measures as we speak.

the most frequent air conditioners being used are the two upstairs.
the rest rarely unless my maid has been using behind my back.
it shud still be running at optimum since I have only been using it for less than 3 months.

vacuum can do much. I have two very young kids plus a cat. so the vacuuming is a must for the cat hair and spilled food.
nope. washing machine no hot water. in fact, the only areas in the house with access to how water are the 3 upstairs bathrooms.

its a top loading Samsung washing machine. very simple washing machine. no selection for hot or cold.
rainbow vacuum cleaner I borrow from my FIL. too expensive to buy. hence the Electrolux vacuum cleaner.

true very true.
at the moment I am switching off at night.
but am also seriously considering to switch it on only for showers and to keep it close all other times.
just to be on the safe side.

my water pump is 500watt
agreed on the suggestions given by everyone. will most probably off the water pump and only use it for the rain shower

my rain shower is 15 inch by 15 inch for 1 head. I have two shower heads.
so I needed to change all the piping to make sure sufficient water flow and add a water pump so gain optimum use of the rain shower.
as for the water pump, there are smaller water pump that may be suited for just a rain shower, but my water pump connects to all my bathrooms upstairs.

the instant water heater will give you hot water, but it cannot be considered as a rain shower and may not have enough pressure.

I can still accept that amount as it expected such an increase due to the rain shower.
