So I need a pump and a separate pressure vessel, as all the pumps seem to have a small one. Do you have a setup in mind Billi ?
No you do not need a extra vessel cause the pump has a small one , but i got a bigger extra vessel cheap and that just reduced the intervals of starting the pump ( found it better for our inverter and not with each handwash or so the pump starts and more equalized pressure during a shower )
I guess these can work as well and are better regulated and no vessel at all , but run each time the tap is on , but keep the pressure nicer
