    Chest Freezer -Power consumption & cost to run

    Chest Freezer -Power consumption & cost to run 24th Jul 08 at 9:40 AM
    Anyone know power consumption & cost to run to expect for a large chest freezer (6ft x 2ft6" x 2ft6" approx).

    I have a large 30+ year old upright chest freezer.
    (probably not as efficient as new ones, but it has lasted all these years considering new hi-tech appliances don't always last)

    It seems to be running all the time, that is I can hear the compressor running all the time.

    Ice builds up a little at top of freezer where the I think the seal is not perfect.

    I have only just thought of this, but the electric cost/power consumption in the house is quite high, considering only 1 person there, they switch of lights & they are working a lot.

    Have just realised that this freezer may be burning money !!

    I have plug-in power meter, so will check power consumption soon.

    But what general power consumption & cost to run (per month/year) would people expect for a large freezer running normally ??

    fwiw, I have a 10yr old Bosch 6+ft tall frost free fridge-freezer. Energy rating 'C'.

    Last time I did any measurements, it was using on average 1.38kWh per day (503kWh pa). At say 10p per kWh, that works out at £50 a year. (More if you factor in the standing charge or primary units)

    Looking in Argos catalogue, the largest fridge/freezers they sell claim to use 400kWh a year, energy rating 'A'.


    If you can find the power consumption for a modern chest freezer which is comparable to your own, you should be able to do a similar comparison.

    Best to use your Energy monitor as they vary so much and leave it connected for as long as you can to get a good average, then you will have definite figures.

    I have a large Bosch chest freezer about 10 years old in my garage.

    It uses about 8.5kWh a week in the summer and 6.5kWh in the winter.

    So taking 7.5kWh as the average it costs me approx £28 a year.

    Old freezer versus new

    I have an allotment and hope to freeze lots of veg that I've grown. Trouble is I only have a small under counter 50mm wide freezer - hardly big enough for ice cubes. I want a freezer in the garage for the produce.

    So do I

    a) Buy a 6 foot high A+++ new freezer from Curry's for about £200 or

    b) get a free old clunker from Freecycle and pay the extra to run it.

    I'm looking at a long term thing here without extended warranty which I never take out. So what is the differencce in power use of the 2 models. Any ideas? As £200 isn't an issue to me the extra power is from a green point of view so What is the extra usage?

    Also going to raise a question about shower versus bath so look out for that.

    You can get an idea for annual consumption of a new freezer from the specification sheet - around £40pa??

    With a 'freecycle' freezer you can monitor the consumption with a cheap plug in monitor, and if the 'economics' don't make sense - back to square 1.

    Wow, with a change in circumstanses ( son going to Uni and me working less) I have had time to think about our freezer.
    We store bargin food in a bid to save money but having to find our watt meter bought years ago it shows our freezer is costing us £113 a year to run that's £28 every bill!
    The freezer was an old one that my parents gave us when we were married 20 years ago. It must be 35 years old.
    Over the last year or so we have eaten lots of freezer burn food in a bid not to waste it so I am now seriously thinking about buying a small one as this one is almost empty.
    I think I have had my lightbulb moment!
    What is the point of paying to store so much food? Apart from fruit and veg from the garden we don't really need a freezer.
    For years I have been buying bulk meat at wholesale from the butcher in a bid to save money, by the time we plough through it it's not at its best and its not as if supermarkets have restricted hours any more.
    Think I am off to look for a small freezer and free cycle the huge chest freezer.

    That's a weird billing cycle you have!

    Edit: Eh? Oh. You've updated it. Never mind.

    Electricity suppliers, hardware stores, libraries, DIY stores, department stores, supermarkets, Amazon.

    Important thing is to make sure you buy a model that keeps the reading in memory when it is unplugged.

    If you use the freezer properly, and have a well functioning non energy guzzling one, it can work well.
    You need to have a list of what's in it.
    You need to keep the dates it went in.
    You need enough space in it that you can buy several months freezable food at once if you come across a bargain of stuff you like.

    My freezer uses around 30 quid a year of electricity - http://www.currys.co.uk/gbuk/household-appliances/refrigeration/chest-freezers/hotpoint-rcnaa300p-chest-freezer-white-17473402-pdt.html?gclid=CIvzueOw-rkCFVDItAodKSoAnQ&srcid=198&cmpid=ppc~gg~~~Exact&m c!!!!!gg_goog_7904&s_kwcid=AL!3391!3!30417874284!! !g!64556564244!&ef_id=UktPfgAABAkdX9D@:20131003094 539:s.

    I use it for many money saving things.
    For example, cook up a really large nice curry - 30 servings or so in a large pot, then freeze into portions in reusable containers.

    Ends up very cheap per delicious meal, and I don't have to cook when I'm not feeling like it.

    It is only worth it if you fill it with reduced goods.
    Otherwise, as you say - other than convenience - there is little or no benefit over a small freezer.

    Do remember to count the cost of the shopping though!
    If you go out for an unplanned shop, you will end up spending more on items you may impulse buy, as well as the cost of transport, ...

    At 120 quid a year electricity cost - you might as well buy http://www.tesco.com/deliverysaver/?rel=external - which will get you free deliveries on about 18 hour notice

    Also - you can easily buy small freezers that use the same electriicy as the above.

    http://www.ide alo.co.uk/cat/2620F740803/freezers.html - you need to edit the URL and put it back together - shows freezers using under 200kWh/year.

    On more concrete savings, the best I've gotten so far was 30kg of chicken fillets, mis-priced at 60p/kg, not a fiver a kilo of above.
