Further to my shower room installation, I am at the point of purchasing a mixer shower.
The Aqualisa unit in the main bathroom is pump fed from the cisterns so doesn't teach me much about selecting something suitable for a gas combi/mains at up to 5 bar.
Most shower head performance is quoted at 0.1 bar so unhelpful.
Where does one start? The combi (25kW) will also feed the kitchen hot tap and CH so thermostatic control might be wise.
