According to analyses of energy experts, heating by wood is the cheapest this year – about BGN 325 for the entire season for an apartment of about 50 sq. m. It is followed by heating by coal but people in big towns use electricity or heating on a mass scale.
Heating by Toplofikatsiya costs about BGN 450. Heating by natural gas costs a bit more despite the price drop in early October.
The most expensive variant is electricity, if we use a heater.
