diverters or gravity?

Instead of using diverter tees couldn't I rely on a lower pressure in the radiator loop along with gravity? By using standard tees and a larger diameter pipe to the radiator, the head loss through the radiator should be less than the head loss through the bypass. Shouldn't it? See attached drawings.

    With the first picture I see almost all of the water staying in the main loop and in the second I see almost all going through the radiator . If in the first photo you used 3/4"-1/2"-1/2" tee it will work.

    I was thinking the same thing. If the second drawing is used the the radiator should get most of the flow and can be turned off or adjusted with manual valves or a TRV without the headloss of diverter tees.
  • What's different

    between the two that makes you say that?
