i've thought about doing that, only thing is it means my fridge & alarm will be out of power 

alarm i'm not so worried...only thing is the fridge.

if i go to TNB with this complaint they will layan?? seems quite far fetch they will actually send a team to investigate given the fact they quite happily accepting my payments.

thanks for the suggestion anyhows...i will check the meter once reach home later.  see if there's a significant rise.

now, i'm living in an apartment <1000sq ft.  me and my wife.  my baby kid (1.5yrs old)comes by to stay with us from Friday-Sunday evening.  he sleeps with us in the same room.  my appliances includes:

1) Home Entertainment system
2) Fridge (LG side-by-side)
3) Microwave
4) Cooker Hood
5) Oven
6) A/C (2 x 1hp & 1 x 1.5hp Inverter type)
7) Water Pump x 1 
8) Water Heater x 2 (storage type not instant type)
9) Bathroom Exhaust Fan x 1
10) Alarm

i cant believe bill to be RM100 or so...i originally tot that would be the case, but now, i'm paying more than RM250 per month for the past 3 months.

just to justify:

Fridge - i've set it to the lowest temp since i started using it.  i cook almost on daily basis (breakfast & dinner) so the size is just about right for my stuffs.

Cooker Hood - only switched on when cooking..if not cooking will immediately switch it off cos its damn noisy

A/C - since last night, i set it at 24c & fan speed no.3.  previously 18c at fan speed 5, pretty much the max...i will continue to maintain it at 24c from now on

water pump - i need a water pump becos i have a crazy big size shower rose.  its 350mm x 350mm.  without the water pump, cant really feel the effect of rain shower.  that's why i need a water pump.  the water pump has a device which will switch off when no water passes thru it.  besides, i switch off the main switch after i use them.

water heater (storage tank type) - 2 or 4 or 8 person nothing to do with having storage tank or not.  the main idea of getting a storage tank is becos i can conceal the tank above the plaster ceiling.  my bathroom is about 38 sq ft.  the actual shower area is 3x3 ft.  if i were to use those instant water heater type means
i will have a huge enclosure inside the 3x3ft area not to mentioned those hose running from here to there. 
i wont be able to use shower rose but have to live with the stock handheld shower head that comes with the water heater.

besides, having the water heater & all pipings concealed means i have a more surface area.  and the entire bathroom looks cleaner, and bigger.

again, as i mentioned, the water heater is SWITCHED OFF whenever we're done with the shower.  it's never kept switched on more than couple of hours a day.  i know all about the high electricity consumption of the water heater, and i do think logically, the heater will try to maintain the temp so it will keep boiling.  so i make it a point to switched it ON only when we need to take a shower & switched it OFF immediately after use.

btw, the 'tank' is only 35liter.  just about enough for 2 person.  its the 2nd smallest tank capacity in the range. 

bathroom exhaust fan - this is only installed in Bathroom 2 which is not used 90% of the time.  the only time it is used is when my baby kid is around and its probably switched on 30mins per day for 3 days a week.
now, just to highlight & update, i did a check immediately after i reach home from work yesterday.  i left home for work at about 12pm yesterday, and reached home at 7pm.  between then, no one was at home and nothing was switched on except for:

Fridge
Alarm
thermos water kettle

and the usage? 1KWH in 7hours.  this kinda make me think that the fridge is not so bad after all.

last night was a pretty normal night for both of us, the usual cooking (1.5 hr of oven & hood), clothes washing, TV and A/C usage with the exception we were out for a movie between 830pm to 1130pm.  this morning, when i left for work at about 11am, the total usage was 14KWH.

if this is my average usage, the meter should be reading less than 500KWH per month.  so i honestly, don't know where the extra 300KWH is from.

i will check the meter again after work later.  and then check again the next morning.  and will monitor the usage over the weekends.  the high usage could be from the weekends.

i dont agree with you on no2

we have implement energy efficiency (EE) on fridge with star labelling

here my fridge

529kwh PER YEAR

which mean about RM100 per year, sound funny yeahhh

but it true, i just set my fridge half power (medium), and before im went to office (about 7.15am), just looking at TNB meter, show 2234kwh and at the night when im come back, just checking at meter (9.00pm) show 2234kwh.... so for conclusion my frigde just consume not more than 1kw per day

Bathroom exhaust fan is power sucker ???

Cant believe this ...

Fan motor not really big watt. Unless, he leave it on for 24hrs

2.) The AC better setting 23deg or below, cause the lower tempeture setting the cold can be maintain, if setting above 23deg the air will warm more easy then the compresor will fully running againt to keep the tempeture u setting it. This is bcos last time my AC has problemn after using 1 year+, the tecnical guy told me.

See whether this black box thing is working efficiently......Due to its inefficiency, I replaced it due a small fire broke up and my electricity bill increased for a few months before I asked TNB to replace it with a new one.
