Vented Twin Coil 200L Tank with working solar Connecting Backboiler for rads and DHW?

[Scottvan]

Hello, I am wondering the best way to connect in my backboiler to the Hot Water tank and rads. I would like to have Gravity feed to water tank but do I need a Laddomat type unit or can I just use a pump, injection tee and 4 way valve to run the rads properly?
Thanks in advance for any input on this.

So is it a thermal store, this twin coil vented cylinder? Need a bit more info on this one.

If I just use an injection tee, does it matter where in the return leg it goes?
