Ultra-fin radiant zone with diverter tees

Hi there!



I'm going to be removing a section of baseboard where I'm installing a new door. It's on the first floor main loop, one of about 5 radiators in that zone.



My idea is to replace that radiator with a zone of high temp ultra-fin radiant in the joists below (I have full access from the basement) piped off of diverter tees. It seems extremely simple:



Remove baseboard

Close the main loop and insert pair of diverter tees

Run high temp radiant zone off of those tees



and that's it - what am i missing? Some considerations that come to mind:



Will the radiant zone get sufficient flow from the tees? I need to run some numbers, but with two tees, supply and return, my guess would be yes. It will be about 150' of 1/2" pex-al-pex.



What if its too hot? I could simply use some valves in the diverter loop itself to limit flow.



What if it doesn't get sufficient flow, even with two diverter tees? I could put a globe valve in between the two diverter tees to force more flow into the loop, but the problem i see there is that I'd be restricting flow to the entire first floor circuit. Hopefully that won't be needed.



Besides the obvious due diligence of running the numbers in terms of tube spacing, number of fins needed, etc... Can you think of any reason this won't work or anything else I need to consider?



Thanks,



Kyle
