Seasonal efficiency of commercial condensing gas boilers?
I am trying to establish a reliable figure for the seasonal efficiency of commercial scale natural gas fueled condensing boilers – say 33-100kW capacity.
SEDBUK publish a table of the efficiencies for domestic units – is there an equivalent resource giving referenceable values for commercial units?

- I need to replace a floor-standing boiler(heating only)is there a suitable condensing boiler for an old system
to re-position any replacement to the current ‘Diplomat’ cast iron model would be very awkward and with an open vented gravity system could I possibly get exemption from John Prescotts ‘SEDBUK A/B’ ruling by fitting the most efficient alternative (as a condensing boiler might not run at top efficiency anyway without significant modifications all round) Why is there no reference from boiler manufacturers to SEDBUK B grade. I think wet Central Heating is getting too complex and I may consider gas wall heaters instead. Are things improving out there regarding earlier ‘teething’ troubles with condensing boilers and are conventional boilers still being manufactured?...
