Working Price of a Washing Machine – Begin Washing in Chilly Water!

Sharing is caring!

Following on from my earlier posts about the price of operating varied home equipment. I’ve been taking a look at the price of operating a washer.

These are just a little tougher to work out than the price of common utilization. Your fridge and Freezer are on on a regular basis, prices will fluctuate relying on ambient temperatures and the way usually you open the doorways and many others.

With a washer, it clearly is dependent upon the variety of masses you do per day or week but in addition the settings used. When not in use, my washer makes use of a bit below 1w of electrical energy.

I additionally solely have one washer, unlikely my two fridges.

After my overly costly sensible Samsung WW9000 washer broke down, I purchased a way more reasonably priced LG F4J6VY2W roughly 3 years in the past.

All my calculations are based mostly on the present variable charge of roughly 0.28p per kW.

Washing in Chilly Water

Historically we’ve at all times been instructed to clean our garments at 40-degrees. Many of the vitality consumption figures offered on web sites assume a ridiculous 60-degree wash.

Whereas that recommendation might have been related 10+ years in the past when the hotter water was required to activate the enzymes within the detergent that cleans our garments and kills micro organism, nevertheless, it’s now not correct in the present day, relying on the detergent you utilize.

Again in 2003, Procter & Gamble had an analysis on its vitality footprint and based mostly on the findings of this, they reformulated its detergents to make them extra environment friendly when used with chilly water. Tide Coldwater was launched in 2005.

After all, you’ll nonetheless need to wash some issues at hotter temperatures, mattress linin and underwear are apparent examples, and hotter temperatures could be good at retaining white cotton shiny.

The true value of operating value of a washer

My LG F4J6VY2W freestanding washer is now discontinued and due to this fact doesn’t have one of many new fashionable vitality effectivity scores. It was A+++, and it acknowledged that the annual vitality consumption was 160kWh.

At 160kWh, this might work out as £44.8 per 12 months to run.

It appears to be like just like the official cycles figures are:

  • 60 °C cotton (Full Load) 0.84 kW
  • 60 °C cotton (Half Load) 0.65 kW
  • 40 °C cotton (Half Load) 0.65 kW

As compared, the present least expensive 9KG machine they’ve is the and has an vitality effectivity score of B.

That is acknowledged as utilizing 58kwh per 100 cycles, with the official cycle figures being:

  • Eco 40-60 (Full Load): 1.011 kw
  • Eco 40-60 (Half Load):  0.500 kw
  • Eco 40-60 (Quarter Load): 0.242 kw

I used a fast wash for many of the exams as a result of it took me much less time. Nonetheless, the size of the wash doesn’t seem to have as a lot impact as warming up of the water. You might be in all probability higher off sticking to one of many cooler however longer washing cycles (if that’s an possibility in your machine).

  • Fast wash: 30 minutes @ 30-degrees
    • Max draw is 2500w, and the overall utilization was 0.23kw
  • Fast wash – 30 minutes @ Chilly
  • Cotton 40 levels

Power Use based mostly on official figures

My pattern of 1 equipment isn’t nice. In contrast to fridges, not all washing machines state common vitality consumption, relying on the positioning you utilize.

Curry’s and John Lewis record vitality consumption per cycle. Curry’s don’t state what possibility is used, however I assume it’s the identical as John Lewis. John Lewis makes use of a ridiculous setting of the 60ºC cotton cycle. I suppose the logic behind that is that it’s the worst-case state of affairs.

AO.com states per 12 months based mostly on 220 washes, but when we divide by 220, the determine remains to be very excessive, so I assume they’re additionally utilizing a 60-degree wash.

I assume most individuals don’t use 60-degrees for many of their washes. Subsequently, the under figures usually are not very correct.

  • LOGIK L712WM20
    • Water consumption per cycle: 45 litres
    • Power consumption per cycle: 0.69 kWh
  • BEKO WTK82011W
    • Water consumption per cycle: 41 litres
    • Power consumption per cycle: 0.62 kWh
  • LOGIK LIW714W20
    • Water consumption per cycle: 45 litres
    • Power consumption per cycle: 0.52 kWh
  • HOOVER H-Wash 300 (H3W 68TME)
    • Similar value because the Logik however bigger capability
    • Water consumption per cycle: 44 litres
    • Power consumption per cycle: 0.55 kWh

HOOVER H-WASH 300 H3WS68TAMCE

  • Most cost-effective A rated
    • Water consumption per cycle: 44 litres
    • Power consumption per cycle: 0.47 kWh

Utilizing the above figures, in case you did 200 washes per 12 months, the most cost effective LOGIK L712WM20 would use 138kWh at a price of £38.64. The official annual determine is 195 kWh or £54.60.

The HOOVER H-WASH 300 H3WS68TAMCE would use 94kWh at a price of £26.32. Alternatively, the official acknowledged annual consumption is 118 kWh or £33.04.

In case you are doing most of your washing at a decrease temperature, these figures will probably be smaller.

Subsequently, if you’re on the lookout for a brand new washer purely on the general value (quite than all the opposite options), there may be little motive to go for a better effectivity however dearer washer.
