Seasonal Efficiency of Domestic Boilers in the UK
SEDBUK
was developed under the Government's Energy Efficiency Best
Practice Programme with the co-operation of boiler
manufacturers, and provides a basis for fair comparison of
the energy performance of different boilers.
SEDBUK
is the average annual efficiency achieved in typical
domestic conditions, making reasonable assumptions about
pattern of usage, climate, control, and other influences.
It is calculated from the results of standard laboratory
tests together with other important factors such as boiler
type, ignition arrangement, internal store size, fuel used,
and knowledge of the UK climate and typical domestic usage
patterns.
For estimating annual fuel costs
SEDBUK
is a better guide than laboratory test results alone. It can
be applied to most gas and oil domestic boilers for which
data is available from tests conducted to the relevant
European standards. The SEDBUK method is used in SAP.
The
SEDBUK
development project
The purpose of the project was to develop a method for
calculating seasonal efficiency for individual central
heating boilers to use in the UK Building Regulations, Part
L (Conservation of Fuel and Power).
