In what way specialists understand the concept of price for heat?
Amount of heat AMOUNT OF HEAT – energy transferred
by means of heat exchange.
1kcal = 0.001163 kW or 1kcal = 4186.8 J
In SI system the heat amount measurement unit is joule [J].
In practice watt-hours [Wh], kilowatt-hours and
megawatt-hours are used.
1kcal is necessary for increasing of 1 water liter temperature by 1º!

Heat price = Heating Price
The price for 1 kilowatt-hour of District Heating:
Heating fee =
Number of kilowatt-hours x price of 1 kilowatt-hour

Conclusions
A. Sooner or later the heating prices in Europe will be equal.
B. Following the statistical data, Lithuania undergoes losses in the amount of 0.7 million EUR within one day of the heating season. This considerable amount of losses occure due to irrational use of heat energy, poor attitude towards the renovation of buildings and engineering systems, etc. Therefore according to the Conclusion A, it is possible to forecast that the losses will be increasing.
