Do note that tariff increase exponentially. If aircond consume 100kwh and heater also 100kwh,but when total up, you have to pay differently.

Like s'pore would be different all flat charge

Bill Summary Jun 2015
Your current account balance of $150.21 will be due on 14.07.2015

Usage Comparison
Your Usage All Neighbours National Average
Usage* Usage**
Electricity Usage 470 kWh
Water Usage 16.5 Cu M

We have 3 units Aircon for 1hp x2 units turn on 8 hrs per night, also 1.5hp for around 5 hrs per dally.
Water storage tank 25L turn on around 3-4 hrs per day, dryer heat pump daily + FL washer daily + hair dryer + Pana inverter fridge 600L & the rest bla bla.

Actually like auto gate non DC & water pump + 2.5hp Aircon may cost you more than average usage
Also non LED lighting too

You can verify it by checking whether the compressor is running non-stop at full speed.

Inverter that always running 100% full speed, won't save you any power compared to non-inverter.

Your maid may switch on the air-cond non-stop when you are not at home.

Any appliance involving heat exchange one normally consume plenty of electricity, eg water heater, boiler, air-cond, fridge etc.

Kawan, yours is old rate.

New Rate is on the Right side. http://www.tnb.com.my/residential/pricing-...riff-rates.html
- 301Kwh - 600Kwh is RM 0.516 + 6% GST
- 601Kwh - 900Kwh is RM 0.54.60 + 6% GST

Autogate don't use much electric, where you get the autogate uses lots of energy? A backup battery can last up to 2 days, if it eat energy, you need a car battery for it.

Non LED, CFL is way better efficiency compare to LED. Lumen / Watt, LED no where close to CFL. And did you factor in Switching power losses?

Not too sure my close to 10 yrs old auto gate non DC type may drink more energy, has few time the fuse broken end out put few copper wires added for extra power, till now never broken fuse already.

If not mana boreh tahan, each time come to servicing and pay for Rm80 just change fuse only

That is motor issue, noting to do with AC or DC autogate, even DC if motor have issue you will blow the circuit board. My mom house using AC sliding Autogate with two AC motor. Everyday using so many round no issue, and hardly notice any high consumption.

But still works fine.. Ya same on both side has motor on ground.
Just wait till can't works then replace to DC motor also slient work.

Look at wattage of the motor will tell the story how much the motor needs to "drink".

Gate motor generally only work for a few second of mins, even the motor is 1000watt (about 1.5hp), it won't consume much electricity bill, as your electricity bill is counted in KWH

If total a month time, the motor work for 2 hours, the total consumption will be 2KWH, at the highest rate of 0.546, the bill will be 2 x 0.546 = RM1.09.

Wow so cheap only

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?

Your RM600+ and RM700+ bill are E bill or N bill ?

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

no diff in terms of tariff used. Just ur advised to upgrade ur power supply to three phase if ur load is exceed 10kW or 50A.

e = estimated bill
n= normal bill

Perhaps you want to monitor how your maid use electricity, is your fridge regularly open for long? And you have any PC running for long hours?

Sometime small things will add up. e.g.
- if you have downlight of 2 bulbs, it take say 36watt, and switching on for 1 month will use minimal 27 units of electric.
- cctv, one unit is about 5watt, if you have 4 units is about 20watt, and switch on for 1 month will use about 15 units. DVR may take up another 10 units.
- Vacuum if use 2 hours a week, it may take up to 8 units a month.
