Many owners of multi-tariff electricity meters in order to save money, run a washing machine at night, taking advantage of the function delay start washing. I found out how much you can save on this.
I have run my washing machine LG WD-12400NDK to the most frequently used programs - delicate wash at 40 ° with spin 800 rpm. This program runs exactly one hour.
To learn how the machine consumes, I took advantage of accurate power meter Robiton PM-2 (ammo1.livejournal.com/827660.html). Line voltage - 225 volts.
When the machine washes clothes, it consumes about 50 watts, when spinning - about 200 watts. The maximum consumption of water during heating - 1850-1900 W, but it does not last long.
And here is the result. In the entire washing machine has spent just 0.41 kWh of electricity.
I pay for electricity of 5.03 rubles per kWh during the day and 1.37 p per kWh at night (Moscow, accounting for two-tariff with electric homes). It turns out that the electric power for a washing costs 2 rubles 6 cents and 56 cents during the day at night.
If you use the car 10 times a month, the difference between the use of day and night will be only 15 rubles. In my opinion, the game is not worth the candle, and it makes no sense to bother with the night washing.
P.S. Of course, if you heat water up to 95 ° and washed with a long extra rinse consumption will grow, but how we learn in the next time. :)
