Flow high or flow low?

[Mdljk]

Hello

I have a new double panel tall column radiator to fit = 325 wide x 1500 high. Looked inside both the header and footer tubes and no sign of baffle plates.

What is the best configuration for flow and return?

1. Flow and return opposite sides low down
2. Flow low down return opposite side high up

I can go with either but for ease of installation #2 Flow low and opposite side high return would suit best.

Any advice gratefully appreciates

Would prefer
