Answer: 
Morning,

Assuming there is a shower or showers, also the fact it is electric a 300L would be the minimum capacity based on three people. I would also advise that if the pressure is poor into the property, an unvented pressurised cylinder would not be any good. With any unvented unit a minimum incoming pressure of 1.5 bar is required and a minimum flow rate of 20lpm, if this cannot be achieved, performance will be poor.

Regards
