Thanks 👍 It's definitely interesting to see they say that a fridge or a freezer costs 99p per day to run. That's over 3.5kWh at the rates they're using. With two fridges and two freezers I would be consuming 14kWh per day before I switched anything else on.
Am I reading it right? 🤔I'm an Eon Next dual fuel customer with no particular expertise but have some time on my hands that I am using to try and help out a bit. -

I'm not sure how accurate the data is, but it certainly gives you food for thought. Only had a quick play with it whilst concentrating on dinner 😋. 😉 -

So a fridge-freezer running for 24hrs would be £1.97. That’s more than 7kWh. I don’t get it 🤔 -

Doesn't sound right. My whole leccy for 24 hours only costs £1.87 inc SC on average. It will start to increase when the clocks change. 🙃

I wonder if you set the runtime for 24 hours it's calculating as though the compressor is running constantly? I think the calculator is more confusing than any use. 😵 -

The typical duty cycle of any refrigeration system is between about 1:3 and 1:5 depending on how hard it has to work, so in an hour, the compressor will be running for only 10-15 minutes. Actual wattage is a misleading metric which is why intermittent operation appliances are rated by average consumption over a year.
A 150W compressor running for 15 minutes an hour, over 24 hours would use 0.9kWh a day. Or around 328kWh over a year. But if you're not opening it and closing it too often and especially if not using in a heated room, you'll probably use a lot less energy.
If the compressor was knackered or the gas too low and it ran continuously, then it course that's 3.6kWh a day, or more if it's an older higher wattage compressor.
Between those two extremes, you might just have a perfectly functional, but older and more inefficient appliance, which seemed to be the scenario @meldrewreborn found himself in. Upgrading his appliance shaved a fair chunk off his consumption.
Just for laughs, I might modify my overflow freezer and fit an LED across the compressor relay just as a visual indication of how often the thing runs. I won't do it to the newer one in the house as it's still under warranty!

Don't shoot me, I'm only the piano player. I DON'T work for or on behalf of EON.Next, but am willing to try and help if I can. Not on mains gas, mobile network or mains drainage. House heated almost entirely by baby dragons. -

Even with the compressor running all day a fridge-freezer wouldn’t use 7kWh. That website gets a 👎 from me. -

My whole house uses that (7kWh) on average in a day. That's a fridge, an upright freezer and an upright fridge freezer plus all the other stuff including tumble drier and electric cooking. If just a fridge cost that amount of energy to run, it would work out cheaper to do the 6 miles a day to the nearest garage and just buy fresh every day and not bother with a fridge!
Maybe the 'standard' they used in the website calculator was a double door American style 'drive thru' fridge freezer with icemaker and drinks cooler?!
And 94p for 24 hours use of a desktop computer? I have a 'desktop computer' that will run for a week for 94p. I have one that will use £3 of electricity in 8 hours if it's running something complex. There's a lot of difference between a dual core Intel Atom with integrated graphics and eMMC storage versus a 32 core Quad Xeon with 64 Gb of RAM and 24TB of RAID HDD storage driving 4 monitors!
Unless they specify the ratings, and the figures they use per kWh....their numbers are purely relative. But to what!!Last edited by retrotecchie; 13-10-23 at 00:01.
