Figuring this KwH cost???
 
I just bought my son a Haier Wine cooler ( Cellar )
He lives in Arizona. { hot in the house } where the electric cost is higher 9 am to 9 pm.

This unit runs 41 seconds then off 41 seconds, then repeats the same cycle.

I called Haier and they said it takes 725 watts an hour to run. this cooler.
I expect the cost is about .10 cents per KWH.

I always use the http://www.super-grow.biz/Electricity.jsp calculator. Basically you're running 12 hours per day on that cycle. What they didn't tell you is the spike that you're going to have with the cycling, but maybe it won't be that big of a deal. It states that you'll be around $.87 cents per day or $26ish per month. There's a lot of other factors involved too though I imagine. The difference in temperature between the fridge and the environment is going to have a large effect on the bill that you can calculate easily I think.

41 seconds on/off cycle doesn't sound correct to me. It should run longer and be off longer between cycles.

The company is telling you the unit will consume 725 watts per hour to run at the on and off cycle they designed. Mutiply that 725 times 24 hours times 30 days. Divide by 1000 to obtain the KWH and multiply that times .10. I get $52.20 per month.

it sound not right for that unit to cycle that much.

is the thermosat is set right ?

is the door closed and sealed propely ?

it possbilty that the sun is shining on the unit to make it work more harder to keep it cool.

those few question should able slove some common issue with it.

Merci,Marc

I didn't even think of it that way. I was thinking it was 725W/hr to run when it was on, not that it was 725W/hr to run 24/7.

I was thinking it was on half the time and off half the time (in 41 second intervals) so I calculated 12 hours per day it was on at 725W/hr.

Personally I wouldn't spend $52.20 to keep wine at a temperature other than what the main fridge would keep it. I'm more of a beer guy though. :laughing:

This is a Thermal Electric unit The doors are very tight, No sun on this unit.
You hear the fan go on and off every 41 sec.
Two settings one for white wine and one for red. The red is the warmest setting 64 degrees. You can't keep red wine in a refrigerator it's too cold.
Thanks deck hand

Something doesn't sound right here, there is no way a warm fridge can consume that much power.

I was thinking that also. My fridge/freezer is only 165 watts and consumes about 85 KW per month.

:thumbup: NEW INFORMATION :thumbup:

Up date
I talked to a tech at Haier again today, they told me that the information I received about the wattage was in error ??
That wattage this unit uses is 725 watts per year
or about 60 watts a month !
a big differance, :yes:

Thanks for all the input. :thumbsup:

That makes more sense. Just over 7 cents per year. :thumbup:

pcampbell 05-12-2008 11:05 AM

The new information seems like too little.

Put it this way, a TV not running will draw 1 or more watts constantly. That is 1 watt for 24 hours a day, 365 days a year or 8760 watt hours per year, or 8.76 kw/h.

I believe my understanding is right, but please do correct me if I am wrong.

I get the same answer. At 10 cents per KWH that would be 87.6 cents per year.
