 **The emergency - when the heating system fails**
-The traditional fan heater can reach 2 kilowatts (maximum). In an old building, a (small) single room may need to be heated using such equipment (when the doors 4) remain closed). This only works when all residents in that district don't have the same electricity demand. Otherwise, the electricity consumption in these areas will increase severely. This is the situation we don't want. Having several fan heaters in use simultaneously in the same building will quickly reach the limit of the electricity network's limit (not to mention the family's financial limit). In a supply crisis (e.g. for oil or gas), municipalities and energy companies will inform constituents and customers when and where fan heaters may be used, as well as how and by whom. They'll employ limited periods for energy use in different buildings and districts to do this. If this already unpopular approach doesn't work, it could cause even more significant problems with the electricity network.

-Thus, electric space heating should use a **heat pump system**, which only uses about one-third of the electricity to provide the same level of heat. This will also curb overall CO2 emissions. At least when the electricity isn't generated by coal.
