Large chest freezer or 3 smaller freezers ??

g4fne

Hi Folks.

I'm currently scrutinising my fuel useage so may see a few questions cropping up


My first question is whether a large chest freezer would be more economical to run than my current 3 old freezers. They are situated in the garage & my current 3 small freezers is costing me approx 11 units over 24hours (almost £2 in real money).

Is anyone able to tell me what a large chest freezer consumes in power in comparison ??

many thanks

Depends on the time of year. This time of year my chest freezer consumes 5-6 KW/h per day. In the Summer (Remember those? - we used to get them!) it's as much as 10KW/h per day.

Wow that's a LOT - I use 10KW on average per day for the whole house! And I run one fridge, one freezer and an old fridge freezer in the garage.

I'm running 17kw per 24hours with my current set up (at home during day). Turned off all 3 freezers in garage (still have small fridge & freezer in Kitchen) and dropped to 11kw for 24hours.
Being that the freezers are all pretty old & battered thought a newer chest freezer would make a significant different :think::think:

Surely then your freezers are costing you 6KH per 24 hours, not 11?

You would be right ..... sorry, i'm having a stupid moment :whistle::whistle::whistle:

On the correct figure of 6kwh (apologies again), it is costing me £1.02 per 24hours & i was told that 2kwh is about the right running cost for a freezer. On the face of it, it would seem my battered old freezers are not as "juicy" as i anticipated.


However on that figure it will be costing approx £350 a year to run them, which is a little more frightening. So .... really back to orignal question.

Can anyone else give me idea of what the running costs are on a large modern chest freezer please ??

Hiya, having 3 freezers in the garage and a fridge freezer in the kitcken running 24 hours will use a lot of electric over the year. Can you not cut down? i understand when buying a bargin in food all to well, but then you are paying the extra in keeping it in the freezer.

Buying a new A rated freezer will help save electric.

I sometimes read posts like this and think "you must have a faulty electric meter".

This .gov website suggests 2-3 kw/h per day per freezer is about right - although it doesn't say what size freezer, but would assume a standard under worktop freezer given it's in a kitchen.

I have one of those cheapie Maplin energy monitors and when I checked the freezer in the garage it suggested it consumed 5-6kw/h per day - maybe the meter is over reading, but it's a 6 foot chest - so 3 times bigger than a kitchen appliance that is supposed to consume 2-3, so I don't think 5 or 6 is excessive...

Have a look at the link above might help

Pincher

288kWh ~ £28.80

The A+ rating has more to do with the insulation property than how good the compressor is.

This is a C rated "small" freezer

252kWh ~ £25.20

So the "large" freezer wins.

Your old freezers probably has old seals that leak, not so good insulation and low on refrigerant, because the technology hasn't changed that much.

You have to pay to dispose of freezers (CFC) so you should try to flog them on eBay. Should have upgraded when they had free disposal offers.

Looking at 'Pinchers' info freezers use less than 1KWh a day. I am always reading my meter, and have done a lot to reduce useage and we now consistently use about 10KWh per day over the year. (£28 a month DD)
