Hot water heat

DV

I am replacing a section of hot water baseboard in my bathroom with a aluminum section. The baseboard comes with a 1/2" pipe size element. My existing pipe size is 3/4". If I install this 1/2" section ,my existing heating zone would consist of the first room would be 3/4", my bathroom would reduce down to 1/2" and then tie back into 3/4" for last room. Will this work?? Thanks DV

Unless

it is monoflow, I would return it and get 3/4"
