pumped shower advice

[rajk]

I have a open vented system comprising of hot water cyclinder + water storage tank + vailant ecotec bolier.

water storage tank is approx 0.5m above hot water cylinder.

I want to fit power shower.
1) Aqualisa or mira digital pumped showers good?
2) Digital or individual pump?
3) Is 0.5m sufficent head height?

The head in question is the lowest point of the cold tank against the highest point of the pump/its associated pipe work. For Stuart Turner I believe a 10cm min head is required although I'd suggest as much as you can manage above that.

providing the digital mixer unit is just below the cws the it's ok on these showers.
