Efficiency % (Gross)
541 76
The gross calorific value of the fuel has been used for this efficiency calculation. The
test data from which it has been calculated has been certified by Advantica
Certification services (0087). The efficiency value may be used in the UK
Government's Standard Assessment Procedure (SAP) for energy rating of dwellings.
The conversion of net efficiency to gross was achieved by multiplying the net
efficiency by the following conversion factor from Table E3 of SAP 2005, rounding
down to the nearest whole number.
