there's an electricity calculator app for Malaysian household on android which i used to estimate my monthly bill and it's pretty accurate!

Can you share which app? I can download on my Samsung note now. hope its a free app.

RM350 is at my old condo.
now at my double story link it is RM700.
it doesn't look good.

it's called My Electricity Calculator by Lazing

EDITED TO ADD WATER HEATER

Hi guys,

Need so input on electricity consumption. I just got my TNB bill and it costs me RM710.40 from 15 May to 15 June. What did I use that could make my bill go so high? Previously, in my old condo, my average bill was RM350.

Back ground information.

I just moved to alam impian in April
It is a 2 story intermediate.
Major electrical items:-

York inverter aircond 1hp x 3 sets = I only use 2 air conditioners from 10pm to 8am (10hours) and from 2pm to 4pm(2 hours) at temp 26c at the lowest fan.
Acson normal aircond 1hp x 2 sets = hardly use
Acson normal aircond 2hp 1 set = hardly use
Grundfos water pump 1.5hp = 1 set which I keep on 24 hours 7 days a week
Electrolux clothes dryer = +/-6 hours a week
Rubine brand built in oven which I use +/-5 hours a week
Rubine brand hood which I use everyday for +/-3 hours a day
Deep oil fryer (no brand) which I use +/- 1 hour a day
LCD 50 inch tv which is kept on from 8am to 10pm (14 hours) everyday (kids)
KDK ceiling fan I use 1 which is kept on from 8am to 11pm (15 hours)
Toshiba 700liter inverter fridge

FORGOT TO ADD:-
1 STORAGE WATER HEATER 35 LITERS
1 STORAGE WATER HEATER 50 LITERS
BOTH USED SPARINGLY

Those I think are the major electrical items which I use daily.
As for the lights in the house, I use 18watt LED downlights for the whole house.

Please help. I need to figure out what is causing such a high electricity bill.

Lets convert to daily usage

- 2x1hp, x 12 hours usage, assuming  you are using 0.4 (assuming 60% the time is off), and ac is 900watt = 8.6Kwh / day
- Grundfos, how long it usually run? Lets assume you run 1.5 hours a day. That about 700Watt * 1.5 = 1.05 Kwh / day
- Cloth dryer, what is the model? Lets assume is 2,200 Watt. you use 6 hours a week. = 6 x 2,200 / 7 = ~1.9Kwh / day
- Oven, what is the wattage? assume 2,200 watt. = 5 x 2,200 /7 = ~ 1.58Kwh / day
- Cooking, what is the wattage? how many burner you use?  Lets assume average is 700watt per hours, = 700 x 3 hours = 2.1Kwh / day
- Oil fryer? how many watt? These stuff usually > 1,000 watt. Assuming is 1,00 watt. use use 1 hours. = 1kwh / day
- LCD x 14 hours, assume is 50 watt x 14 = 0.7Kwh / day
- KDK Fan, 15hours x 30watt (assume) = 0.45 Kwh / day
- Storage heater, lets assume you use total of 1.5Hours a day in total of 2 storage = 1.5 x 3,000 watt = 6.0Kwh / day

That already using 23.38 unit per day.  Yet to include your fridge, lights, computer, charger, Water boiler?

If your A/C are in open area, meaning it will run longer, can be running 100% all the time too.

Did you switch off the heater when not use?

And how many burner did you wife / maid use during cooking? more burner mean more electricity.

Remember, convenient and comfort come with cost.

You can first cut the use of dryer, that is one, and start switching off storage heater when not use. Also reduce the A/C usage. It help keep you healthier too.

ok can you please provide the units consumed in old condo and now in new condo? what was the 6-mth average?

i suppose your meter is the digital type?

hi! try removing the ground fos pump!  I can tell from my experience, it consumes a lot of electricity! My dad use to have a fish pond.

i share the same concern as you for high electricity usage/bill.
if possible monitor your meter on a daily basis. say you take a reading at 7am, do this everyday at 7am. Then each day you only use certain appliances. I think you can figure out which is the main culprit

to pay more than Rm300 for one particular utility is really ridiculous

Unlike fish pond, the pump function here is to increase water pressure and it just turn on and off on demand only, I believe

yup. that is correct. I checked with my seller zheine from builders hardware on the grundfos usage.

Other than your appliances, the other major influence that was not mentioned is the space itself. Compare to previous place, how much space difference and how well insulated or confined the space between the two. Inverter or not, this can be major factor of electricity usage by air-conditioner.

I'm not sure why you need to use storage but since you switch off after use, it is not main problem. Leaving it on can make huge difference.
