I think my usage is about the same as yours except no alarm system.
My laptop with power switch on is around 4-5 hrs a day.
My aircond 1hp Panasonic inverter is on 8 hrs (sleeping time).
TV is also around 3-4 hrs a day.

This is the most consuming electrical appliance besides the fridge which is obviously 24 hrs.

The highest I get is only aroun RM100, that's when I got 2 aircond on for 8 hrs at night (parents visiting), and most lighting on.

My normal electric bill is only around RM70-RM80.

What is your rate? Sometimes condo or apartment is more expensive.
Mine is:
First 200 unit - 0.218
Then it's 0.334
Never reached the next tier, so don't know what's the rate.

The highest rate I reached is 359kwh which the bill like I mentioned above - RM96.71

Also, look at the "Jenis Bacaan" whether or not it's "N". If it's not, tele your bill's meter against actual reading see whether or not the same. If not, then complain to TNB to ask them to come and do actual reading.

Eh my airond is always at 22c.
Forgot to mention I got a LG washing + dryer combo and roughly around 2 times per week which usually took 3 hrs to complete the cycle. Still the electricity didn't go up that high.

I still don't think TS's usaged would be that high.

Maybe like what ozak mentioned; the bolier heater could be the main culprit. The rest I think is normal.

I still believe you should check your meter against your bill and make sure that the bill "Jenis Bacaan" is "N".
If it's not "N", meaning they are not doing actual reading but estimation. I still don't believe that your bill would go up to RM250.

If the bill is indeed "N", check whether the rate is the same as I posted. Like I mentioned, the rate could be more expensive for Condo and apartment. (Pls correct me if I'm wrong)
