The Seasonal Efficiency Domestic Boilers UK (SEDBUK) is
Class 'A' : 24cxi - 90.3%, 30cxi - 90.3% & 38cxi - 90.6%.
The value is used in the UK Government's Standard Assessment
Procedure (SAP) for energy rating of dwellings. The test data

1.5 Condensate Drain
A plastic drain pipe must be fitted to allow discharge of
condensate to a drain.
Condensate should, if possible, be discharged into the internal

can be made externally into the household drainage system or
a purpose designed soak away, see section 8.2 for more
details.
