Table 2 - General Data
Note.
To obtain gas consumption, divide gross heat input (kW) by a calorific value of 37.8 (MJ/m

)
GENERAL
*
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.
