Table 2 - Performance Data
Note.
Gas consumption is calculated using a calorific value of
38.7 MJ/m
3
(1038 Btu/ft
3
) gross or 34.9 MJ/m
3
(935 Btu/ft
3
)
nett
To obtain the gas consumption at a different calorific value:-
a.
For l/s - divide the gross heat input (kW) by the gross
C.V. of the gas (MJ/m
3
)
b.
For ft
3
/h - divide the gross heat input (Btu/h) by the gross
C.V. of the gas (Btu/ft
3
)
*
The value is used in the UK government's Standard Assessment Procedure (SAP) for energy rating of dwellings.
The test data from which it has been calculated have been certified by BGplc 0087
