In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
I have a tt 110 with a combination of baseboard heat and inslab radiant. Here is my question, when all the zones are calling, i am getting almost 30degree delta t. I assume because I am getting the return water from the baseboard at about a 20 degree delta when it is running by itself. The low temp zones when running by themselves have about a 10 to 12. The inboiler pump speed is on speed one. If all the zones are calling, is that limiting the flow to the boiler or is it just the result of low temp and high temp return water mixing together? I have taco 007 for each zone. Each radiant zone has a 3 way mixing valve.
For example, last night, outdoor temp was 26. The setpoint was at 144 and the return temp was 108 with all zones calling. The mix valves were at 100 degrees.
Thanks in advnce
