Which typical household appliances like blender, kettle, stove, laptop, TV etc. Consume the most electricity within a short time? So almost the most kWh. Which devices strain the power lines the most?
Purely theorteisch it is the electric druchlauferhitzer with usually 21 kW, however, he charged the line to the device itself not so strong, since this is designed to be correspondingly thick. Mostly 4 x or 5 x 6 mm²
The same applies to the cooker (combined or stand-alone appliance) with 10 kW and a connection cable 5 x 2.5 mm²
in the "schuko-class" so devices with Schukosteckern, this should be simply the built-in oven. With 3 to 3.5 kW so 13 to 16 amps he literally gets out everything that goes… Even the tumble dryer falls into this area. Also old washing machines.
then come then things about the 2 kW as kettle, fan heater etc…
Generally speaking, look at the nameplate. On the devices are kW-data. A device with 2kW, which runs continuously for one hour, then consumes 2kWh… So kW * operating hours = kWh. Although kettle has 2kW as a rule, but is also only about 5min. Thus, the kWh are also in the 5 min and only about 160 Wh (0,16kWh)
It depends on the performance and the operating time of the devices, how much kWh are actually consumed…
These are two different questions:
"most current in a short time", "load on the power line": for the power (watt) is crucial.
"the most kWh": The energy consumption is decisive for this and, in addition to the power, the switch-on duration!
For question 1:
There you can look at the rating plate, or at the amount of heat that the device produces.
Top is clearly the stove (hotplates, oven). That can go up to 10kW power. (Only hot water instantaneous water heaters could have more.)
Then come hot water boiler, dryer, washing machine, kettle, toaster, coffee maker, waffle iron, fan heater, hair dryer, vacuum cleaner (0.8 to 4kW).
Far lower are then lamps, blender, refrigerator, laptop, TV, electronics in general (few watts to a few hundred watts)
For question 2:
Since the switch-on duration here, even devices in continuous operation can devour just as much energy as a supposed large consumer. For example, A TV in standby may need more than a kettle, which runs only 1-2x a day.
