Worchester Bosch junior 28i new shower question.

[Benp]

Hi. I am a plumbing novice. I have just had the above boiler fitted and am fitting a new bathroom and shower. I have checked water pressure as it sent abit low but it was 9litres per minute as in specification.

My problem is I want a new powerful shower but am unsure what system I can have. When I did the house I put a 10mm cable in so electrically can have anything. With the combi I have can I have a mixer, or any of the others? What would give me the best performance and what would be a suitable bar of pressure?

As I said I am a plumbing novice so sorry if any questions are abit basic.

Thanks in advance

you should get about 11 litres/min with a temp rise of 35°C.
If you have enough water flow on your cold supply(ie enough to supply your hot plus some) any shower whose specs are within your supply rate/pressure should be suitable.
