GENERAL
Note.
Natural gas consumption is calculated using a calorific value of
37.8MJ/m
3
(1038Btu/ft
3
) gross or 34 MJ/m
3
(910 Btu/ft
3
) nett at
15ºC and 1013.25 mbar.
a
. For l/s divide the gross heat input (kW) by the gross C.V. of
the gas (MJ/m
3
)
b. For ft/h
3
divide the gross heat input (Btu/h) by the gross C.V.
of the gas (Btu/ft
3
).
Propane gas consumption is calculated using a calorific value of
95.7 MJ/m
3
(2500 Btu/ft.
3
) gross or 88.0 MJ/m
3
(2300 Btu/ft.
3
) net
at 15ºC and 1013.25 mbar.
To obtain the fuel consumption in liquid form divide the above
figures by 270.
* The value is used in the UK Government's Standard Assessment
Procedure (SAP) for energy ratings of dwellings. The test data from
which it has been calculated have been certified by a notified body.
