Consumption figures of electrical appliances
Here are details of the electricity consumption of some key household appliances. Further information on the energy consumption of individual appliances is available from the household appliance guides compiled by Helsingin Energia.
Electricity consumption is given as an average reading from new appliances. We lend consumption meters for easy and accurate measurement of appliances with a plug connection. Factors affecting measured consumption include the efficiency and operating time of the appliances, adjusting the temperature control (thermostat), way of using the appliance, and its positioning and care. Many appliances consume electricity even when not in use (stand-by current).
A low-power appliance may use a significant amount of energy if used for a long period. For example, cold-storage appliances have a low power, but because they are constantly switched on, they are significant energy consumers. However, an iron, which has a high power, but is used less often, has a minor impact on the overall electricity consumption. The stand-by mode of electrical appliances also consumes electricity.
Electricity consumption can be calculated by multiplying the wattage of the appliance (e.g. lamps) by the period of use. Wattage (W) is converted into kilowatts (kW) by dividing it by one thousand. (For example, 60 W / 1,000 = 0.06 kW)
The electricity consumption of an incandescent light bulb (60 W) for eight hours is 0.06 kW x 8 h = 0.48 kWh.
By multiplying the consumption (kWh) by the price of electricity, you find out how much the use will cost.
