Background Electricity Usage 8760 hours a year

We replaced a very old American fridge/freezer that used about 3kWh per day last year with a new American style one, that claims to use 1.2kWh per day. Quite a nice saving in energy usage, but it will never pay for itself in its lifetime, even at today's electricity prices.

1.8kWh/day at April's prices would be £184/yr. Over a ten-year life that's £1840.

I'm sure it's possible to pay more than that for a fridge/freezer, but most people don't.

It's a very nice fridge/freezer! Its predecessor lasted 26 years. If this one does last that long, it might pay for itself, but I'm not holding my breath.

It's rated to run at 140w. It's 250L capacity. What do the newer freezers run at these days? Appreciate it would be rough calculations only but do you reckon I would actually save if I were to spend a few quid on a new freezer?

FWIW I bought a Beko FFG1545W probably about two and a half years ago IIRC, certainly pre-pandemic.  It was then rated A+ at 249kWh per year, 130W, defrost power 182W.  (Presumably that's average /peak?)

Now it's rated at F under the new system and 266kWh per year.

I'm very pleased with it and can highly recommend it, the old one had lasted over 30 years but was a right pain to defrost and its temperature regulation had become a bit wonky.

It would have been worth getting the new one just for the convenience of being frost free.  It's also one of the very few models that can be used in a garage or outbuilding because it's rated down to -15C whereas most only go down to +10C.

The Kyoto is a hardy beast. It lived in the garage for 3 years, even during the beast from the east, where there was an actual snow drift in the garage. So that doesn't worry me to much. It's more the energy saving Vs outlay that I'm looking at. 

My calculations are if it runs 20 hours a day at 140w that's 1022kwh/yr at 20p that's £204/yr

The beko runs 266kwh/yr at 20p that's £53. 

So paying £339 that should, in theory, pay for itself in 2 and a bit years. If my maths is right (I'm not sure it is?)

So replacement makes sense assuming the newer one lasts the distance?

Today I found out that when my washing machine is not in use, all the lights are off etc it still used 5W 

ie 5 x 8760 x 28p = £12 a year for just sitting there !

Going forward I will switch it off at the plug when not in use.

In general, I am finding that things that have a hard on/off switch use nothing when switched off, but things that have a soft press to switch on use a few watts when not in use. It can mount up.


Edit: my coffee bean grinder which you press a button on top and it grinds enough beans for a cup of coffee uses 2W doing nothing.

I think it's predecessor held up very well. (Cue they don't make em like the used to comments)

Unless faulty, it is very unlikely to get anywhere close to running for 20 hours at 140W.

The equivalent rating of the new one is 130W Vs 140W.

Do you have a plug in energy monitor, or a Smart meter, or at least know your background/overnight usage?

Do you have evidence that it runs 20 hours per day?  Most of the time a garage is likely to be cooler than the kitchen so I'd expect the duty cycle to be a lot lower.

However, the main problem is likely to be getting electricity at only 20p/kWh, at least for the foreseeable future.  But at least it means the cost of energy savings may be greater.  The temperature control on mine is accurate and is in 2 deg C intervals.

I don't know for sure that it runs for 20hrs. But it isn't in the best condition and it hums a lot of the day. Granted is probably not cooling the whole time though. It's not in the garage in this house either. It's in the kitchen now. 
I have an IHD for the smart meter. I'll plug that in any see what background overnight is. I only have the fridge, router and freezer on overnight. So I'll turn the router off and see what the measurement is in the morning. 

Or I'll see about investing in a power meter. It would be interesting to see what various things use anyway.

we brought the same one last year and I noticed the energy rating had changed, but we are pleased with it. 
I have actually turned it off at the moment as we don't need the extra storage space presently. 
I was wondering whether to sell it as it seems to have gone up in price since last year! We padi £339 last jan and it's now £399!

I am trying to calculate given the cost of running a freezer if it is worth running one - I know you save money by freezing leftovers etc but even so ...
