I've currently got an open vent system that includes a recently installed Vaillant EcoTec Plus 424 boiler. Does anyone know for sure whether this boiler can be used in a sealed system?
I currently have to use a pump on the shower feeds but it's noisy and has to be used early morning when the family are still in bed. The hot water pressure to the taps elsewhere isn't great, but the cold is absolutely fine, so I'm considering the option of going down the sealed route.
I don't know what size the current cylinder is but does anyone know what a ballpark figure would be to get the job done? It's an 18 year old 4 bed detached house if that helps.
Thanks.
