I have a triple coil cylinder onto a systemlink.
From the systemlink there is the DHW feed to the cylinder.
At the bottom of the cylinder is the ECO/Solar coil.
I want to pipe the DHW supply through the ECO and DHW coils to make
maximum use of the heat output.
Would it be best to pipe the ECO then DHW coil in series
pipe them in parallel.
The ECO coil then would get minimum flow as it is low down
and T'd off the supply to the higher DHW coil.

Thoughts and suggestions welcome !
