Help with calculating the cost of an appliance.

I have a home network attached storage (NAS) device which I leave on continuously 24 hours a day; it rarely gets turned off.

Over the last year our electricity bills have been considerably higher and I'm trying to work out what it could be. I have suspected the NAS device but need to be 100% sure.

According to the set-up I have, the manufacturer quotes the device would use "32.76 watts per hour".

Could someone help me determine how much this would cost?

1000watts is 1kw so that could be around 10 -16p per hour depending on the energy supplier

33watts (round it up) isnt a lot but obviously if its on 24/7 365days a year it could be a enough for a good night put

Get a energy monitor from Lidl like this one

To expand on savemoney. 33w for 24 hours = 792w.
Multipy that by yor rate per kwh, say 10p? and that comes to about 8p per day.

I'd grab an energy monitor like the one above as you NAS device in theory will draw differing amounts of power dependant on its usage. This largely depends on the NAS itself as well as the internal hard drive/s and how it manages its power. when you are accessing the drive it will probably draw 33watts, but I doubt it would draw that if the discs arent spinning.

The other thing with buying one of these monitors is you start looking at what everything else uses... never a bad thing.

I do not believe this figures that the NAS manufacturers quota. I used to leave my NAS on 24/7 and I noticed an increase in my electricity consumption by about 2 to 3 Kwh per day. Seeing as I used to use 12 Kwh per day in total. this was quite a large percentage increase and equated to about 100GBP per year.

Mine has an automated shutdown feature and I have it timed to turn off every night now and my elecy consumption is back down again.
