Just wondering if there are any Viessmann installers on here as I've a question about pump overrrun on the 100w combi. I'm just considering one at the minute, haven't bought it (yes I know there are other boilers available but this one is ticking a few boxes for me).
Whereas most boilers have an overrun based on time (and parameters can generally be adjusted from say 3 mins to 60 mins), the Viessmann 100w is based on a temperature drop, and Viessmann UK tell me that after CH has been on, it could take over an hour for the pump overrun to stop in theory, all depends on pipe runs and how well insulated the house is. I'm just wondering what it's like in practice. Equally if any owners of this are reading then I'd be grateful for your comments. Whilst I do understand the point of pump overrun, I'd say anything over a few minutes would drive me mad as I'm a bit OCD about noise!
