Full speed ahead on your project! Sounds great.
My only caution would be that brazed plate HXs are really efficient, but given that you want to do an open loop project, a brazed plate HX will be prone to fouling, over time. This is due to the fact that in closed loop situations, there is a limited amount of 'foulants' (did I just coin a new word?) but in an open source the supply of foulants is unlimited.
Tube-in-tube (or similar) would be the correct choice here. Acquario and also Randen have successfully built their own tube-in-tube HXs... check them out.
