Hi guys, I've recently had a loft conversion and decided to get a new bolier installed at the same time.
My plumber decided to remove our tanked system in airing cupboard (this is where the stairs are now located) and to install a viessman Vitodens 111 35w combi up in the loft conversion.
Prior to installiation we queried the combi (several occasions) as we wanted to make sure the bolier was suitable for our now 4 bathrooms 3 bed house (2 ensuites, main bathroom and downstairs loo) but I was guaranteed it would to sufficient.
Boiler has since been installed and we do not have the pressure in our ensuite in loft conversion if the water is running downstairs. For example my daughter was running the bath downstairs and the water would trickle out in our ensuite in loft.
Our plumber came back and advised our water softer maybe causing issues so we got a new one installed which is the best on the market to improve pressure, annoyingly this didn't help! (water is however very soft). He then fitted restrictors to taps and baths excuding loft ensuite and this also hasn't helped. We also have good mains pressure as our property is only 12 years old.
My question is can anything be done / fitted to help the pressure? Secondly would any of you choose this bolier ahead of a unvented tanked system?
Amy advice would be appreciated
