This is the best available estimate of annual average efficiency when installed in typical domestic conditions in the UK, and it is used in SAP 2009 (the government’s methodology for calculating the energy performance of dwellings). For boilers which have been tested for full-load efficiency and part-load efficiency and the results accepted for the database, the SAP 2009 annual efficiency will be SEDBUK(2009). For older boilers, where test data is not available, the SAP 2009 annual efficiency is a default value based on type, age, and fuel.
SEDBUK stands for the Seasonal Efficiency of Domestic Boilers in the UK. This is an estimate of the seasonal efficiency of a boiler installed in typical domestic conditions in the UK, and is used in SAP assessments and the building regulations. It is an annual average, calculated from full-load efficiency and part-load efficiency test results and other data.
The organisation responsible for the operation of the MCS scheme.
Stands for the Microgeneration Certification Scheme and is the scheme operated by GEMSERV, for the independent certification of microgeneration products and services in accordance with consistent standards.
