As far as bypassing the water heater, the bypass system can consist of one, two or three valves. Yours just has one and that is correct as there will be a one way check valve on the hot water output line.
This thread may help explain (post #5 especially):
BTW, from your pic in your first post, your hot water tank is currently bypassed with the way the valve is turned.
