What spec would I be looking for to install a suitable shower on a gravity fed vented direct system?
Suitable shower

If you can, I'd suggest an Aqualisa quartz pumped.
They are expensive but I've never had a complaint with one. The pump would ideally sit above in the loft and the pipework is all in the shower rail (no chasing walls out and minimal mess!) you just need a suitable power supply to the processor unit (pump)
The only requirement on this shower is that the cold tank is higher than the pump. I've found this shower to be very good to fit most systems.
I hope this answers your question as you weren't very specific about what you needed to know??

As it stands at the moment CWSC is located directly above the bathroom. The vertical distance between the CWSC and Shower head is about a metre so only about 0.1 bar of pressure.
The hot water is fed via an immersion heater.

A quartz would work!
As long as the processor is lower than the tank you're ok. This is usually easily achieved as the tank is on a stand in most cases. The hot water is not a problem.
If the processor can't be put in the loft, an airing cupboard will do.
The quartz is an all in one package as the pump and shower are together. You don't need to worry about buying a pump or a shower that are suitable with one another. Aqualisa also have a generous guarantee on this product.

There is a space under the CWSC that pump could fit, what size is the pump?
And what current rating do they operate at?

Have a look at this...

It gives the processor dimensions and probably the rating of the supply. I think it's 3 or 5 amp.
Im sure there is no issue with a direct cylinder. I've just realised you put "direct" and not "indirect" in your first post. I have found aqualisa to have a good technical department for advice too. There number should be on the above link.

They give you approx 16l/min on a 3amp fused spur.
Aqualisa one isn't bad but not the best.

I've recently pumped my shower using a 2bar dual pump. The ppmis situated in the airing cupboard on the floor and is plumbed in 22mm. Originally I had a shower which adapted to 15mm through a thermostatic mixer. The pressure was pretty good and was impressed.
Anyway I decided to fit a bath and hence re plumbed a bath/shower mixer in 22mm and ripped out the shower mixer valve and 15mm tube. Basically I have a direct feed from my cold water storage tank and hot water cylinder to my bath mixer. Without the pump on the flowrate is good. I then switched the pump on...**** me the power and flow was immense! I changed the shower hose from the mixer to the shower head as the one supplied with the mixer wasn't long enough. I noticed the bore size was slightly bigger. When I tested the shower with the pump on and new hose it was like a pressure washer. It's crazy! When I have a shower I can only have the valves open about 30% because it's incredibly powerful.
Anyway...all I'm saying is that from my experience it's not just having things pumped, feed sizes and any restrictions play a big part!
I'm just now dreading my water bill!
