Split Loop

The traditional way to do this was with a square head balancing cock ( plug valve ) The unit would be started and the return temperature checked on each branch with all valves full open. The highest return temp would be closed until it was the same as the other ones. The valves are then left in this position. You could try using ball valves, you should only need one on the small head zone. You could also do this with zone valves is a bit of control is desired.

SPLIT LOOP

My home is on a concrete slab with one zone/loop with baseboard heating. Because of the uneven heating from the beginning of the loop to the end of the loop I am splitting the loop. Unfortunately Im not in a position to split the loop in half. One loop will be approximatly 80' long with approximately 46' of baseboard. The other loop will be approximately 118' with approximately 57' of baseboard. Im using a standard tee for the 2 loops into a 1" return. My question is will there be a difference in flowrate for each loop resulting in unequal heating? Do I have to use some kind of flow control to even out the flowrates in each loop? Does the longer loop require a higher flowrate to even out the heat? If so what is the best way to do that?
