Those individuals and to small and medium-sized businesses who are faced with the construction or renovation of housing or production away from large cities and even in the outskirts of their well-known problem limiting access to electricity. Yes there periphery, sometimes within the city limits of allocated capacity will be "ridiculous." In many regions, "+ electrification of the whole country" ended at the level of electrification plan. And each schoolchild can tell you that in those hard times, even the most inquisitive minds could not imagine an electric power 2000-2200 watts each house.

If you have installed individual room thermostats and the temperature is low, and from autumn to spring it usually is, the feeding of electricity all the floors are applied simultaneously, as the house is still cold, and good cause overload of the central line.
