Too many monoflos?

This horrible cold snap has prompted me to upgrade my short kitchen baseboard to a panel rad to get sufficient heat. I’m currently making the shopping list. After I add the rad to my first floor loop, it will be: 16x72 panel rad, 24x48 panel rad, 24x36 panel rad, 18 ft 3/4 baseboard in that order. The loops is 3/4” with the rads hooked up via 3/4x1/2 Venturi tees and the 3/4” baseboard in series.

My question is: is it detrimental to have dual Venturi tees for every radiator? The rads are above the loop and at most a 6’ run horizontally from the loop. We installed the original 2 rads with venturis on return and supply per my father’s (the plumber) recommendation. I’m concerned if we get to 3 Rads with 2 monoflos each that the flow will be negatively affected and the baseboard section will be seeing too cold water. The pump used is a taco 010. I’m considering installing the new rad with only 1 Venturi on the return and the swapping out the existing supply monoflos for regular tees as well. Thoughts? Is this much ado about nothing? Thanks.

You only need one per radiator unless it's below the main..It will affect flow for sure. 0010? Is this to overcome the added friction loss? Is it noisy? Mad Dog

The choice of a taco 010 was due to having 4 zones and probably a bit of insurance pressure. No not noisy at all.

And when you say 1 monoflo per rad, it seems that people are always putting it on the return. Anyone ever use just one in the supply?

If the heat emitter has high flow resistance, it may need to have two diverter tees.

Here are a few other piping options for one pipe systems.
