determining size of water expansion vessel

[shezzaar]

how do you determine what size of expansion vessel is needed for each job?
Also, how do you decide what size of radiator is needed for a particular room?

thanks in advance

Thanks for your quick reply.
thanks also for the information
do you have any ideas how you would find the size needed if it was for a back boiler or thermal Pv installation?? As the only calculations would be for the amount of water in the pipes, (if what I was thinking was correct).
thanks again
