Thanks. Both Vaillant 937 and Cdi42 installers think pressure and gas pipe are fine. I have to chose between the two???? I am also assuming a system boiler with 24kw + some storage scores better on quick bath fill and not so much on tap response time vs the combi. Is that correct?? many thanks

Would a normal shower be around the same? If it is only 4-5lt/minute per shower - would there be a pressure problem with 2 showers on a 42 Cdi

I need a new boiler for runnig two showers at the same time. Heating is for 3 bed flat. Does an average shower at an average temperature (good for avearge people) need 10 litres/minute? Will 937 42 Cdi work? Many thanks.
