Browse Forums General Discussion 1 Jan 27, 2011 8:48 pm The builder is providing 160lt tank with one solar panel with gas heating. I have heard that if one installs a 160lt tank with 1 panel we may run out of warm water, and we need to have dual pipe runing otherwise it can reduce the water pressure if hot water is opened at 2 places. Could someone please guide me with this. How to have equal pressure if taps opened simultaneously and do i need a 350lt tank with 2 solar panels.

We went for a larger tank - can't remember the size now, but I think it's 215L - with two panels, with the idea of getting the maximum "free" hot water possible for our family of five.
