How much does it cost to run a portable air conditioner, and how quickly does it cool a room? [Updated with 2022 prices]

Sharing is caring!

UPDATE: This was at first published back again in 2021 and someway considering that then, back again then all we had to get worried about was a pandemic. That’s nonetheless a problem but we now also have war and a value of living disaster. What a time to be alive. I have consequently up-to-date this submit with far more accurate pricing, to mirror the astronomic selling price increase of electric power. This is correct for May well 2022.

With the temperatures continuing to soar and the Fulfilled Workplace issuing an excessive heat warning, a lot of of us have been on the lookout to buy a moveable air conditioning unit.

If, like me, you are vaguely knowledgeable of these, you will know they cost a great deal to operate, they are loud, they are major and awkward to use with British isles based windows.

This yr, I at last caved and purchased an Inventor Magic 12000BTU Moveable Air Conditioner from Amazon, which is now out of inventory.

Advised Portable Air Conditioners

How significantly does a moveable air conditioner charge to run?

The main concern with air conditioning is the price to operate it. The power use will differ dependent on the cooling ability of the device. This commonly ranges from 1Kw to 1.3kW for air-con models rated from 9000 to 12000 BTU.

My Inventor Magic is rated at 1350W for every hour for cooling. Precise use appears to differ involving 1100W and 1300W, and this appears to be to normal out at 1200W while it is operating entire blast.

Charge to operate an air conditioner in 2022

I am currently with SO Strength which has a unit price of 13.6476p/kWh (I chose them for the reason that of the cheap electrical power owing to me operating a ton of personal computers). You can indication up for SO Electrical power listed here.

This then performs out at 16.38p for each hour to run, which appears to be really low cost, seriously.

I still left the struck-out text earlier mentioned just so we can all feel frustrated about how low-priced electricity was.

A variety of tariff examples:

• 2021:
• 2022 (May possibly, Variable Tariffs)
  • British Gasoline Typical Variable: 28.021p for every kWh

SO Energy and EON Future is not going to provide variable tariff details as they are not getting new customers.

Primarily based on the previously mentioned selling prices, last 12 months it was costing me 16.38p per hour to run and now it would expense 33.60p or a 105% rate raise.

Final 12 months I pointed out that operating this by alone applied up just as substantially electric power as the relaxation of my house and the charges will insert up rapidly, just twice as quickly this calendar year.

My overall view has not altered about them, aside from that it expenses 2 times as substantially. If you plan to depart a single of these on all working day, then you are in for a terrible time when you get your power statement. Of training course, the air con will swap off when it reaches the preferred temperature (and back again on) so you may possibly not be functioning it all the time.

Air conditioners were being often highly-priced to operate and staying a limited-fisted northerner I would hardly ever operate a single all day. Even so, when it is painfully scorching outside and my office is touching 30-levels or my bed room is 23+ levels, I feel paying 67p jogging an air-con for a couple of several hours is still well worth it. They are really noisy in any case so I might favor to have them working as very little as probable.

How rapidly does an air-con interesting a place?

I am continue to tests it and have only just started off retaining an eye on temps and instances. Thinking about the current heatwave, I thought I’d get some information out faster and insert far more exact quantities over time.

In 2 hours 15 minutes, it used 2.5kW of energy and cooled my office environment from 27-levels to 21-degrees. Subjectively it feels cooler, I think the neat air going about the room helps make it appear to be colder than it is. My business office is 4.5m x 3.5m and is 2.5m large, so just shy of 30m3.

How loud are transportable air conditioners?

Genuinely rather loud. I never have an precise sound meter, but working with my cellphone, it reads 40-50db with the air-con just off to the facet of me. The seem profile isn’t much too poor, it is not high pitched and just appears like a lover on higher velocity. I can cope with it switched on in the place of work, but there is not a chance in the world could I slide asleep with it on. I strategy to great my bedroom to one thing a lot more nice and then switch it off when I go to rest. I will vacation resort to a tranquil pedestal admirer if it will get too incredibly hot in the night time.

How large are air conditioning units?

They definitely vary a ton relying on their score. The Inventor Magic 12000BTU is 1 of the bigger-rated styles out there and, therefore, physically big.

It is possibly about as tall and wide as an underneath-counter fridge but considerably less deep. It weighs 35KG, so it wasn’t all that entertaining carrying it up the stairs by myself. If you preserve it on the identical ground, it is not way too poor as it is roller wheels on it.

How simple is it to in good shape a transportable air conditioner hose by a United kingdom uPVC window?

The Inventor Magic 12000BTU comes with a home windows kit, but this appears to be for sash home windows (the classic home windows that slide up).

I have uPVC home windows that are top rated hung, which is for that reason not compatible. There are many kits you can obtain on Amazon, which are generally bits of fabric with zip and velcro that adhere close to the gaps in the window. From my quick expertise with them, they are a bit garbage, and I am quite sceptical of the huge selection of Amazon reviews some of them have. Sadly, this would seem about the greatest solution, absolutely for momentary use.  It is significantly from great, and they are quite hideous, but it is what it is.
