  "text": "(a)The useful efficiency values ηn , ηp and the useful heat output values Pn , Pp shall be measured, as appropriate. For solid fuel cogeneration boilers the electrical efficiency value ηel,n is also measured.\n(b)The seasonal space heating energy efficiency ηs shall be calculated as the seasonal space heating energy efficiency in active mode ηson , corrected by contributions accounting for temperature controls, auxiliary electricity consumption, and, for solid fuel cogeneration boilers, by adding the electrical efficiency multiplied by a conversion coefficient CC of 2,5.\n(c)The consumption of electricity shall be multiplied by a conversion coefficient CC of 2,5.",
