QSEDBUKQSEDBUK is no longer available.At the start of 2006 the contents of the SEDBUK boiler database (used by QSEDBUK) were changed so as to omit the boiler minimum output - there is no good reason we can see for this change, since the field formerly used to hold the minimum output is now used to hold the maximum output, a value already in the database. This change makes it impossible to sensibly select a boiler by output, since there is now no way of knowing whether (say) a boiler shown as having an output of 18kWh will only run at this output or whether it is a modulating boiler which will happily run over a range of 6-18kWh. The latter would be eminently suitable for a house with a heating load of 8kWh and would give quick DHW reheat; the former would spend its time cycling and would not be a good choice. Until now we have continued to make QSEDBUK available with the last usable database, but this now excludes too many current boilers, so we have sadly taken the decision to withdraw what many people found to be a useful program. We will look to reintroduce QSEDBUK at a later date if the boiler database specification is revised.
