12 home appliances that consume the most electricity


Energy prices are rising every day. And given the approach of winter and the government’s call to turn off energy-intensive household appliances, citizens are already looking for ways to save energy.

Minister of Energy Kostas Skrekas, during the presentation of new subsidies for the payment of bills for November, recommended (so far recommended) to reduce electricity consumption during peak hours, that is, from 18:00 to 21:00.

What appliance consumes the most electricity in your home? An analysis of the demand for electricity during non-working hours shows that among household appliances, the most energy-intensive is the electric stove. A small burner has a power of 800 to 1000 watts, medium ones of 1500 watts, and a large one can have a power of 2-2.5 thousand watts.

In second place among home appliances in terms of the amount of energy consumed is the air conditioner and electric heater. Depending on the power (BTU), the air conditioner can consume from 1 to 10 kilowatts / hour. Electric heaters rarely have a power higher than 2-3 kilowatts / hour, but their efficiency is usually lower than that of air conditioners, and in the end they consume almost the same power.

However, the electric water heater consumes the most, its power can reach 4-5 kilowatts. Fortunately, it does not work for long, and its final consumption usually does not exceed 10 kilowatts per day. However, if you have lovers of washing at home several times a day, this figure can increase significantly.

First of all, in order to calculate consumption, you need to know the power of each household appliance, that is, the number of watts consumed in normal daily operation. Every device usually has plate with its electrical characteristics. In extreme cases, you can see them in the instructions. We are interested in the power indicated by W or W, for example, it can be explicitly indicated on the device – 40 W, or amperes “A” must be multiplied by 230 V. Let’s say 230 V 0.17 A can be indicated on the fan – this is approximately 40 W and etc.

If we assume that the electric kettle works for 20 minutes every day (4 times 5 minutes), then this is 0.66 kWh per day and, accordingly, 19.8 kWh per month.

Using the microwave 5 times a day for 3 minutes at full power, we get 0.25 kWh per day or 7.5 kWh per month.

An air conditioner (or heater) operating for 8 hours will wind us up from 10 to 30 kWh per day, and 300-900 kWh will come out in a month. Agree, this is quite a lot.

Which devices are the most energy intensive:

  1. Water heater (from 1500W to 5000W)
  2. Oven (from 2000 W to 4000 W)
  3. Air heater (from 1000W to 3000W)
  4. Hair dryer (from 1800 W to 2500 W)
  5. Electric stove (from 1500 W to 4000 W)
  6. Electric kettle (from 1200 W to 2500 W)
  7. Air dryer(1000W to 4000W)
  8. Dishwasher (from 1,000 W to 2,500 W)
  9. Iron (from 1,000 W to 2,500 W)
  10. Air conditioning (from 900 W to 10,000 W)
  11. Washing machine (from 2,000 W to 3,000 W)
  12. Vacuum cleaner (1 500-3 000 W)

We remind you that the Greek authorities have appointed sizes subsidies for electricity at the place of residence of citizens without income criteria and regardless of suppliers, which can somewhat help with paying bills:

  • consumption up to 500 kilowatt/hour: feed-in tariff of 238 euros per megawatt-hour (the subsidy covers 90% of electricity price increases),
  • from 501 to 1000 kilowatt-hours, the feed-in tariff (subsidy) is 188 euros per megawatt-hour. If a household reduces consumption by 15% compared to 2021, the subsidy will increase by €50 per MWh,
  • over 1000 kWh the subsidy is 50 euros per MWh.
  • A feed-in tariff (subsidy) is set at EUR 286 per MWh for households included in the Social household tariff (KOT).
