Heat Plants
Heat plants, refers to plants (including heat pumps and electric boilers) designed to produce heat only and who sell heat to a third party under the provisions of a contract. Both main activity producer and autoproducer plants are included here. Heat pumps that are operated within the residential sector where the heat is not sold are not considered a transformation process and are not included here – the electricity consumption appears as residential use. Columns 1 to 8 of the Energy Balances Table, show the use of primary and secondary fuels in a heating system that transmits and distributes heat from one or more energy source to, among others, residential, industrial, and commercial consumers for space heating, cooking, hot water, and industrial processes.
