    Abstract : Popular Abstract in Swedish Konceptet fjärrvärme inbegriper central värmeproduktion från vilken värme distribueras ut till de enskilda förbrukarna via ett rörsystem. Ett grundläggande krav, med hänsyn till fjärrvärmens konkurrenskraft, är att vinsten som görs i den storskaliga värmeproduktionen, jämfört med lokal värmeproduktion, överstiger kostnaderna för värmedistributionen.
