All electric flat.

I have 2 bed ground floor all electric flat. The hot water pressure is pants. Economy 7 storage heaters, . There are,3 of us in the flat. Is a 120lt tank sufficient. Do I need a indirect or direct tank? Can this year dad's as well.
Asked by: Taz1940
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
