OT? Giving up on using the fridge. How?

Hi,



I have one of these useless mini-bar fridges that I basically only use to keep the milk from going bad.



However, now it starts getting fresh in the kitchen and I can leave the milk outside and it still stays relatively fresh.



These mini-fridges, despite being small, consume a lot of energy (about £1 a day on top of standing charges, on a SSE PAYG smart meter tariff).



I know that I should clean the fridge when I switch it off (defrosting is not necessary as there's no freezer department) and that I should leave the door open.



How should I clean the fridge? Is water with vinegar a good solution?



How long should I leave the door open once the fridge has been switched off and cleaned?



Once the fridge is clean and dry, can I just close the door and wait until next heatwave?


Not sure about best fluid for cleaning it, but usually (e.g.at our Village Hall and elsewhere) the advice seems to be that once off, leave the door ajar. Fold a cloth and leave it over the top of the door to stop it closing.

You would leave it open.

You can clean the surfaces on a fridge, but if any water pooled in the unit for any reason, it could go into the insulation. You can't be sure you got all of the ferment-able liquids. It's the things you can't see, that stink.

That’s poor. Our big American style fridge freezer with ice maker uses

2kWhrs a day, a bit less than 80p on our current tariff

Having said that, it could be a lot more on a PAYG tariff.

Seems popular.

Until you turn it on again.

Try it and see if it gets stinky.

Given its poor efficiency I’d be inclined to look for a replacement on Freecycle (or similar).

My solid state mini fridge takes a week to use that much.

As much as mine or as much as TLO’s? Would be useful to know what he’s paying per kWhr.

Sodium Bicarbonate is better - use a strong solution and wipe with dry cloth after to clear any residue.

Always leave the door ajar to allow air to circulate.

I bought a new under counter freezer in July, energy usage went from

35.86 KWh June to 12.88 KWh August.

It only cost £160 so will pay for itself quickly.

Monitoring done via ATHOM/TASMOTA plug and Domoticz runing on a rPi.

Sorry for being unclear. I was commenting on your 2kWh a day, which is about what mine consumes in a week.

Comparing a mini fridge to an American style fridge isn’t a terribly helpful comparison for consumption though.

Comparing your mini fridge with TLO’s mini fridge’s consumption would be a lot more helpful. According to wiki though, peltier fridges have a relatively poor efficiency so his might be peltier as well. He’d probably be better off with a small compressor fridge.

Unfortunately, he only gives us the cost, not its consumption, or the price he pays per unit.

According to wiki though, peltier fridges have a

Most of the mini fridges seem to be aimed at the hotel room market, so silent operation is important, hence the use of Peltier effect. I didn't find any compressor fridges in the same size when I wanted one.

My defrosted upright big Freezer has been off for several weeks now, the door is propped open with the three pin plug and lead. All seems to be ok with no odour.

If you dontneed a freezer box and only need to keep milk from going off for 3 days then this is the case study for a 21 wine bottle peltier effect wine cooler used as a fridge. No vibration and little noise , only as much noise as the fan of a desktop computer. In an unheated kitchen ,so not having to fight, excluding inci=dental cooking heat, 120W consumption at full tilt or 24W after reaching temp and then as continuous background consumption, but no off state, as the intended use. Using an old "clockwork" time switch with 24*4 quarter hour setting switch wheel and whenever it comes on is full tilt for only 1/4 hour. Nightime 4 hours off,1/4 hour on, 4 hours off then on for 1/4 hour every hour in peak summer during the day, every 2 hour in lesser summer and down to 4 hour off, around the clock in wintertime, you work the math for lecky consumption.

Minibar fridges are mostly peltier cooled. These are terribly inefficient & don't normally get down to safe food temperature, they're just drink coolers. Bleach is a better cleaner. Fridges should be left open when not in use, to avoid pongs. Using a timer or thermostat is not recommended, peltiers fail when repeatedly switched on & off. Small proper (compressor) fridges are available, but expect to pay more.

I suspect the TLO is a she not a he.

Yes. On an outside windowsill. Buy milk daily, then, in the evening boil it up for your Ovaltine and put the rest in a jug for your breakfast cereal or porridge. Skim off the cream as a treat.

Or put chilled milk in a Thermos. You used to be able to get large vacuum flasks with a plastic lining big enough for bacon &c.

Or just use a fridge like everyone else. We don't have to go back to living in caves yet. (If we did there wouldn't be any problem as caves are always cool.)

On an outside, north-facing windowsill, draped in a damp tea towel.

Not much chance of that these days as most milk is homogenised. Who buys milk daily anyway? ;-)

Talking of caves, anyone else watched “Thirteen lives” about the Thailand cave rescue?

15 days in a cave wearing just football kit. I presume cave temperatures are a bit warmer there than here?

Utterly remarkable rescue. Well worth a watch (on Amazon Prime).
