I've just had a new (viessmann 100)) system boiler installed as a replacement boiler to our central heating system which has 2 heating zones and an unvented DHW cyclinder all controlled by programmers/ programmable roomstats and cyclinder stat.
I was only told during the installation that, because of the weather compemsation control, the system could only be set up to provide water OR heating - i.e not both simultanesouly.
Can anyone tell me if this is an issue which arises with weather compensation control of other manufacturer's system (i.e not Combi) boilers (e.g Worcester bosch/ Baxi etc)?
Seems an obvious disadvantage to me - but Viessmann don't make it clear in their literature and neither did the installer - until too late.
