How much my dryer costs/month to run?


My electric bill increased 3-fold after having a child and I'm trying to find out how since we're not cooking the extravagent meals we used to anymore, have no time to watch TV anymore, but we are washing more often and doing more laundry since we do cloth diapers.

The dryer I have was a top of the line Kenmore Elite He3 Energy Star and 4 years old. The inside of the door says 120/240v 28A and 3 or 4 wire, I pay $0.22/kW and we run it 1 hour/day (or 31 hours/month). How much would it cost/month?

I came up with $45.80 worse case scenario but I'd like that double checked as I'm confused with the 120/240v 28A statement since that means different watts. It is plugged into 240v. Thanks

Yup, same figure I came up with. But what about the washer? You are using that more as well, and how about the water heater?

Your right on the money. 240 volts @ 28 amps = 6720 watts.

6720 watts/1000 = 6.72 Kw per hour.

6.72 Kw x 31 hours x .22 per Kw = $45.83

What about heating/cooling?

Before baby, we both worked and didn't keep the house as warm/cool while we were at work and at night.

But with a SAHM, the house stays heated/cooled 24/7. Plus, since we keep the door to baby's room closed, it tends to get a little cooler in there during the winter, so we've always had a space heater going in there until they were old enough to sleep under blankets.

Of course the other thing... is this a one-time event (i.e. 1st month you've seen a huge increase) or has this been going on for 3 months or more? If this is only the 1st month, there is the possibility that the meter was misread. This just happened to us last month on gas (was running $200 during the bitter cold, then the cold lets up and we get a $450 bill... double checked the meter and the reading on the bill was way PAST the current reading).

Just one months bill went up or several months ?
Make sure they are not estimated bills
Is the house at the same temp ?
We turned up the heat when our son was born & ran a small oil filled radiator in his room to keep it warmer at night
Our washer pulls 7a so that increases power too
Bottle steamer, baby monitor + who knows what else my wife had for our son when he was born
She was home for I think 6-8 weeks with vacation & maternity time off

It's been 3 months in a row, the electric bill has always been around $65 then after the baby it's been around $180 since.

I heat with wood, and have solar hot water so my heating & hot water is pretty much free. The thing with solar is the more we use hot water the more efficient it becomes.

The washer is an He3T that's also 4 years old. I have a Kill-A-Watt device which measures electricity I'll plug the washer into it and hope it can read it (it can't read devices with large Amps but maybe the washer is low enough).

Thanks all. That explains $45 of it, thanks for mentioning all the new baby devices as my wife does have a "wipes warmer" that's on 24/7. After plugging the kill-a-watt into the washer for a week I'll check what that thing is doing.
