Go to the section entitled "1. Active Direct Systems"
Look at "Figure 2 Additional system components" to see a basic drawing of an active-direct system (A type of open loop system)

Yes I did but I was questioning it.
Why would you really want to use a potable loop it seems to me that it is cheaper perhaps? even in Greece and Cyprus (95%) solar energy heated sytems the indirect method is used.
To have that loop direct to the tap with no regulation is that normal? Surely the supply side is regulated to the taps with a blender valve TMV set to 50c say?
I'm beginning to see now why a TPR valve might be used as the cylinder is the pressurised vessel subject to temperature also so if it didn't blow on pressure the cylinder could reach stagnation itself possible?.
Perhaps you could send me a link to read about the systems you are installing I'd like to read up on them, thanks.
Perhaps make it a indirect circuit and fix a plate to plate heatexchanger between the tank and the collector and pump both sides triggered by the temp of the store and the flow from the collector.
