Is it possible to provide pre-heated water into a direct water heater unit
by adding a valve into the mains water feed going into the unit and by-pass
the use of a tank?

Yes, but without some kind of storage, you could only collect heat at the same
time as you are using it - not very efficient.

so how about a loop-back system flow that only allows flow out of the array
once a pre-defined temp has been reached?
