This is driving me up the wall so I hope someone here can help.
Had a new boiler, Veismann 100, put in during summer but it has underperformed since the central heating went on. It seems to take ages (eg 12 hrs) to reach required temp (21c) on mild winter days (8 or 9c outside) and gets nowhere near it on real cold days (2c or less). CH plumbers have been back several times and tend to blame existing pipework.
I have pointed out that boiler manual says bolier water temperature range is 30-80 yet if I put it on highest no (6) temp reads only as 65c and if I push as far as I can (before hitting a reset point) it increases to 68c. This doesn't seem right but cuts no ice with CH plumbers (local firm)
Any comments/suggestions please.
