contact rinnai and look at their infinity water heaters or look at Andrews water heaters.
20 lpm wont run 10 showers (2 lpm each?!), You may need some large water storage

Why not LPG fired, cheaper and better than electric.

I agree with DM. LPG is the way to go on an installation of this nature. We have done it in rural sports clubs quite a lot. LPG water heaters, buffer tanks & solar panels, quite commonly done now.
This is really a VERY expensive senario to cater for fully.
We have 32 people who need showers!
At just 5 min per shower and 10 li/min that will take 1600 litres of water.
By mixing preheated water with cold then 1000 li of 60° of hot water might just do the job in the summer.
But the flow rate will need 100 li/min to run the 10 showers and a bit more if they use the toilets.
So water storage of 1500 litres ( with the balance made up from incoming mains flow rate which also has to refill the toilet cisterns.)
Then that storage has to be pumped to about 1.5 Bar @ 100 li/min. Thats about FOUR Grunfoss pump sets on just two stand alone pumps if you want a litle redundancy.
This will cost perhaps £12,000 installed for starters if electrically heated, maybe more if on LPG. I dont think the added complication of gas is warranted for such limited useage.
