Although, frankly, fir this kind of thing you need to pay for proper advice.

You're not in Luton by any chance?

Occupancy is only 12 permanent. But the pool us shared by community and over weekend has the most people over which range from 20-30

This is beyond realm of DIY. It involves pipe sizing calcs as well as storage capacity. You need to hire a consultant/specifier to design the system.

Edit: Secondary return and blending valves would also be on the list.

Actually we have an existing electric water heater that is leaking and needs to be replaced. It is a 400 gallon tank heater with 90kw power. We think this is an overkill for the job. So we want to purchase a properly sized heater for the job.
