my usage is 20kwhr a day with
- one aircond 1.5hp running 9 hrs
- a pond water pump runing 24hr at 230watt.
- No water heater, use solar with water pump
- electric hop, cook 6 days a week
- electric oven, seldom use, if use one time = 1 kwhr
- microwave use to cook rice once a day, 6 times a week
- two fridge
- only 3 ppl in the house

When off pond water pump and aircond, 14 kwhr a day
When use the electric oven for the day goes up 1kwhr

The new meter was installed on 21st Feb.

Ya, just wonder how come your record is so low. You got a defective meter fr TNB? I have to be careful since the change of meter and watch it evryday because there are many news that TNB just charge thousands of rm to some people accusing them of stealing power and if dont pay they cut supply. It could be their meters that are faulty who know if we are unlucky to have these defective meter and now you got one, hahaha...

This is what monopoly is all about, dont pay, cut. Any problem with meter, your fault, you curi!!! Cannot make enought money increase rate. You have no 2nd choice, no competition.

You see, if the meter is performing below, it is you curi. If the meter is overcharging you rugi. Whatever QC or standard there is no 100% the meters are accurate whether electronic or the old meter. There is no body to check if the meter is good and perform over 10, 20 yrs. You know traders are required to change their weighing machine from time to time yet TNB no need, it is up to them to make the call. Malaysia boleh. Double, triple standards we have.

That's right .

Get one watt meter and test one high power appliances and test, switch off all others including fridge and wait and watch.

About aircond. For every 1 degree lower consume a lot more than the previous degree . For every one degree lower it is not same, the lower the higher per degree comsumption. Eg. from 29 to 28 = 1unit of power, fr 28 to 27 = 1.1 unit of power, 27 to 26 = 1.3 unit, something like this. The most effecient is set to auto where the aircond adjust itself to be 1 or 2 degree colder than the air temp outside. That save electricity. If you set more than 2 degree lower than the outside temp it will consume much more. Most mordern home aircond has this function.

When you need to be lower, it is better to use higher horse power so that it will "not" consume more power than it is needed. With higher power aircond lower temp can be achieved sooner and therefore "save" power consumption. for example if you use an underpower aircond and set it to 16 the aircond will keep on running, no off and yet cannot achieve the desired temp, ie. 16. It is therefore important to know your need and also to select the correct size/power of your aircond.

If you use too high power aircond you will also have problem. The aircond will keep on and off within minute and you experince unncessary short period too hot and too cold. Witinin minute the aircond on to cool the room, becuase it is so powerful it cool so fast and it goes off then on again as the other part of the romm was warm air flow into it.

Why you need to set to 23?. You use comforter and wear heavy cloth?. Yes to really enjoy sleeping in aircond room is set the temp to low, very low and use comforter like winter. But due to $$$$ cannot tahan the bill I set to 25 and use light blanket and wear little. For normal day in hall I set it to 1 degree lower than outside temp. A one degree cooler than outside feel comfortable in the house and comsume little power. You see there are many ppl have aircond in the hall and dont use worry about bill but if you know how things work you enjoy what you bought and pay little. May be a lot of ppl dont understand this. Just give you a situation using fan. when you sit under the fan with the fan on you feel so much comfortable than without the fan on even the fan is at low speed. A little different make so much different and so much more comfortable but if you swtich the fan to max speed the feeling of comfort is not much different.

The circuit are parallel. The appliances in both.

when it is parellel you get the max voltage and max amp. Some appliances especially those consume high power ones and it has two or more power functions and not to over load the house circuit when switching on both or all of them the circuits inside have to be in serial. For example you have an electric oven and cooker combine in one, you can on max the oven to 3kw, on other time you can on the cooker to 3kw, that does not hurt your house circuit as the max power for that particular circuit is 3kw or 13A. But when you on the oven to max 3kw and at the same time you swtich on the cooker to max, the oven power will automatically drop to say 2kw and the cooker to 1kw, or 1.5kw oven, 1.5kw cooker or the sum of the two never exceed 3kw. That is serial circuit with the objective of not melting your house circuit wire. In this sense when you think you often use both then dont buy something of combination but seperate, ie. cooker is cooker; oven is oven. Hope this helps.

Added on April 14, 2012, 11:44 pmThe subsidy dont go to us. The subsidy goes to the IPP. TNB buys expensive electricity from IPP and sell cheap to us and the govt pay TNB for the price difference plus profit, something like that. Know who created the IPPs? The longest serving PM lor. So the present PM is telling you in whatever way the govt pays for it for TNB to make money. If TNB dont make money we got no electricity and new technology as money is needed for investment for future building bigger power station, etc, etc...

Read the bill carefully. It is usually 2 months once for "normal" reading and inbetween "estimate" reading. I got a bill for 72days which is more than 2 months also 700kwh.

Still for your case 700kwh for 2 months is very high. Something is very wrong with the meter otherwise if shoult be: You forgot to off aircond? You did not close the door of your fridge properly and the fridge is running 24 hrs or the door did not seal properly airtight?

You can do a check to the meter. You shut off all electric power to your house before you both go to work, record the meter reading, switch on a lamp or few items like fans with total 200watt. When you come home after 10 hrs the meter should increase by 2kwhr. Get one watt meter to measure the wattage of these things like fans to be on the accurate side.

First you got to make sure the last reading (12 June) was an estimate or actual (normal reading).

2nd, is your house mate on the aircond during weekend to confirm the high 700kwhr bill.

You measured the meter when no one at home(only fridge and routers were on) and it moved about 1-2 kwh (9-10 hours). This shows nothing abnormal with the meter but still it is on the high side as fridge if no one opens the door it should be "off" most time than "on" and fridge takes only 300watt or less for a small fridge I assume since only 2 of you and nothing much in there if not making ice.

Same time you said "Yesterday I recorded it used 18kwh just in one night, I don't even on my aircon (my housemate was using his)." A 1hp aircond is around 800watt (or 1kw if old one). Assuming it is 10 hrs it should not consume 18kwhr even if it is on all the times even with your fan, fridge and some lighting or router on. It should be 10kwhr over 10 hrs.

It is difficult to judge unless you monitor and record reading everyday. To cut short first you got to check if the aircond of your housemate is not at its optimal performance. That is to say the air cond keep on even when it is set to 23. It could be due to filter clogged, lack of gas or outdoor unit is block or fan running slowly. To know that is to on the aircond shut all windows and doors and after an hour go in the room and see if the aircond will off and on and off and on. If it on longer than off then the aircond need service or be replaced.

Alternatively you sleep in yur hoursemate room and he goes to your room and you on fan and he use your airocnd and you compare the meter reading if it is anywhere hitting 18kwhr, since your mate cannot sleep without aircond.

After confirming the aircond, if it hits much way below 18kwhr then it is his airocnd that is the source of the problem. and if it still hit 18kwhr you then have to get yourself a watt meter and do like I said before to confirm the if the meter is faulty.

One other thing, it could be the aircond and the meter, both.

I got a watt meter, where you stay or work?

Weikee, That shows how efficient TNB is and we have to pay for their inefficiency with tariff increase everynow and then to make sure they make profit, huge profit! You put it correctly WTF!@#!@#!@#.
