I need to replace a floor-standing boiler(heating only)is there a suitable condensing boiler for an old system
QUESTION: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?
ANSWER:
You could replace your controls if the boiler is in sound shape (the boiler I work on is 30 years old and the piping is over 90 years old) If you have radiators I would replace the steam traps on each radiator if you haven't done so in the last 5 years. These traps are located on the outlet side at the lowest side of the radiator. Also the chemical balance of the water is critical to the proper function and efficiency of your system.
