This value is used in the UK Government’s Standard
Assessment Procedure (SAP 2005) for energy rating
of dwellings. The test data from which it has been
calculated has been certified by 0086.
SEDBUK (2005) Declaration
NOTE:
All data in this section are nominal values
and subject to normal production tolerances.
IMPORTANT:
Where Low Flow Taps or Fittings are
intended to be used in the DHW system connected it is
strongly recommended that the DHW flow rate DOES
NOT fall below 2.5l/min. This will ensure reliable
operation of the DHW function.
