While the energy consumption in order to obtain the complete decarburization of white heart fittings is greater than the energy consumption used to obtain the only partially decarburized black heart fittings, the investigation has shown not only that the cost for energy represents a small proportion of the total manufacturing cost, but also that in terms of actual energy consumption and the cost related thereto, the difference between the two processes is not significant and depends more on the specific production set up and its energy efficiency of the producer concerned.
Uurimine näitas, et kuigi valgest tempermalmist liitmike täielikuks süsinikutustamiseks vajalik energiatarbimine on suurem kui mustast tempermalmist liitmike osaliseks süsinikutustamiseks vajalik energiatarbimine, moodustavad energiakulud tootmise üldkuludest väikse osa ning kõnealuse kahe protsessi tegelik energiatarbimine ja sellega seotud kulud ei erine üksteisest märkimisväärselt ning sõltuvad pigem asjaomase tootja tootmisseadmetest ja energiakasutuse tõhususest.
