Original: CHP or a bottoming cycle captures the by-product heat for domestic or industrial heating purposes , either very close to the plant , or -- especially in Scandinavia and eastern Europe -- as hot water for district heating with temperatures ranging from approximately 80 to 130 ° C . This is also called decentralized energy .
Simplified: Combined heat and power captures the byproduct heat for domestic or industrial heating purposes , either very close to the plant , or - especially in Scandinavia and eastern Europe - for distribution through pipes to heat local housing .
