Heating with electricity is expensive
Yes, power out of the socket is currently expensive. But the costs may have to be considered in the overall process: on the one hand, modern radiators have storage facilities and precise control, so that power consumption can not be compared with old night storage radiators. On the other hand, the acquisition costs and operating costs are much lower. But also the use and the room size play a role.

Electric heating pollutes the environment 
Not at all! The energy transformation opens up completely new perspectives for electric heating. When run on clean electricity, it does not consume fossil fuels and does not produce CO2. And if you use it with your own solar system, you have the only really 100% eco-friendly heating system.

Electric heaters are inefficient
On the contrary: Electric radiators have an efficiency of 100%, so they work very powerful.
