Power to the people, 19°

Sheryl G. 15°

I'm on a mission. My last power bill was over $600!! Two adults and a child live in this house. This has been pretty typical for us for the past 4 years or so and every now and then I complain to my power retailer. Occasionally they will offer advice but generally they just want to know when I'm going to pay them. I'm going through the laborious task of working out precisely what's hogging my power.

I wanted to throw a couple of things out there for comment.

Firstly,about 2 years ago I complained to my retailer (and then the energy complaints commission when they ignored me) as I believed that we were suffering from a low-voltage problem. After waiting for weeks for action I finally managed to get someone from the network provider out here to test, and sure enough it was confirmed that low voltage was the problem. Several weeks later they finally finished upgrades and the toast was toasting and the jug was boiling in no time at all. During this time I did some investigation and heard a few rumours but no real evidence that low voltage puts a strain on appliances and is liable to make them inefficient. Since I moved into this house 5 years ago I've had 3 washing machines, 2 fridges, 2 dishwashers and an oven all fail. At the time of these failures I assumed it was just bad luck, but now I'm not so sure. does anyone know if this is true?

And secondly, why on earth don't the network providers for electricity infrastructure test to make sure that households are getting an efficient power supply? I shouldn't have been the one to have to tell them I had a voltage problem!

noticed that it was taking longer and longer for various appliances to do their job. Imagine a piece of toast taking 10 minutes to cook. I could have a shower in the time it took to boil the jug.

The challenge is great . Have you got a real smartmeter so you can see whats being used and the cost ?

Not yet Tim but I may have to do that. So far I've been eliminating things I know to be big guzzlers. Our hot water tank is a shocker even though its insulated. What I can't work out though is I took our one and only heater offline - it was on a timer for our very cold bathroom - and found it was using a whopping 10 kwH a day. But something still managed to use those 10 units regardless. Today is the BIG test. All circuits are going off to make sure the meter's not still running. The house was closed up for about 2 months once when we were away. But I still got a bill for $120 one month. In July we averaged 62 kwh per day on one meter (the hot water is on a separate one) and I don't believe we have enough appliances on to scoff that much. Interesting. i guess I'll get to the bottom of it but will probably need a smartmeter to do it.

Wow - what an interesting puzzle when it's not one's own! It must be incredibly frustrating for you! I have a small power meter (got it from Bunnings for about $20) that you can plug individual appliances into to see how much power they are using.

But in your case I would suggest a Centameter which can give you much more comprehensive info on exactly where your power is going. It's more expensive but I would think you can probably recoup that money in a single month if you can get to the bottom of this strange situation!

Good luck, and do let us know what you discover.

Thansk Linda. I'll be shopping for a centameter tomorrow. I'll keep you all updated. To be honest I think I'll find I'm just wasting power somewhere. I look forward to power bills that I can pay without a frown on my face.

Bumped into the previous owner of the house yesterday and they had always had huge power bills too but never got to the bottom of it. One thing I've noticed though is that we have a couple of chandeliers with 6 bulbs and we use a lot of lamps because the lighting in the house is terrible. My exercise for tonight is two-fold - (1) put a meter on the office that has a couple of laptops, a fileserver and switch along with various other bits & bobs to see what its costing a month and (2) counting up all the lightbulbs in the house and adding up the total wattage along with the estimated hours used. I'll bet I'm going to be horrified. Just worked out my fridge is costing about $40 a month to run!

Is this an old house? We owned an older house in Westport that had power leaking into the metal conduit in the ceiling cavity. Very dangerous and costly too. We moved out during the renovation process, so didn't get to see how much difference in power use was achieved. Renting a house now that has a power leak in it too. The electrician is hopefully going to track it down and replace the faulty wiring tomorrow morning...

My partner and I spent some fun time over the weekend checking out the power consumption of various appliances (we live such an exciting life!) We used our cheap little power meter and went around plugging things into it and looking at how much power they used while on standby. There really are some shockers!

Also Sheryl, have you replaced all your light bulbs with energy-saving bulbs yet? With all those lights in your house you might find it makes a big difference to your power consumption. Take a look at http://www.rightlight.govt.nz/

Hi Sheryl.
We have a centimeter and i really rate them. We have an older model and apparently the newer ones are even better. You just have to turn something on to see how much power it uses. When we first got it we went round the whole house and did that. Now we just watch it and when it gets high we go around and turn something off. We are also having trouble with our rental property but I think that it is probably cheap electrics not low voltage. But your bills sound very high. I am complaining about $300 a month. In a house we renovated we managed to get them down to $180 oer month all year round. That included energy efficient bulbs, heat pump hot water cyclinder and two heat pumps to heat the house. They say the centimeter will save 20-30% on your power bill within the first month or something.

Hi everyone, thought I should report in on my findings. I'm become a fiend and everyone in the family is cursing me. There's a little girl who loves baths up to her chest and she's complaining to anyone who will listen that I don't let her fill the bath up. I suspect some good samaritan is doing a "cuckoo" sound when I come near to warn her to turn the water off! lol!

Anyway, what have I found? Well I'm not convinced we have a problem ... we just use way too much power. I've decommissioned a heater on timer in a bathroom that I thought was only on for a couple of hours a day - turns out it was set to be on for 10 hours! Bingo ... that's at least 10 kwh per day. Heated towel rails have gone off. Chandeliers with a million bulbs in them are not used as much. The flat screen TV uses about half a kwh a night to run from about 7pm til about 11pm so that's a killer. We've turned off one hot water heater in the sleepout that was servicing a once a day shower for one person but was using 7 kwh a day. The heated towel rail fell off the wall when someone leaned on it so that's off and won't be fixed just yet.

I've become like a mad demon running around with my little Elto and as a result we've halved our consumption, so I'm pretty happy with that. The problem is I go to other people's houses and start wandering around to see what they're wasting power on.

If anyone wants to know about power use then consult me - I'm an expert and I'm free. I know it all now.

LOL @ watching other people's power consumption! I did that when I first got my power meter too. At first it's just fun then it becomes an obsession!

I do recommend changing your chandelier bulbs for power-saving bulbs. Even if you replaced every second bulb it could make a significant difference.
