Sounds like swimming weather at 4 degrees. We don't run a thermostat after break in but have to monitor heat in the block when testing in the spring due to cold water.
Thats true with transfers.

Do You leave therm/reliefvalve all away? I opened that plastic core and took thermo element&spring out. Center portion flows now all the time and then have to find/make softer spring for the valve.
Made those watercavity mods You see in a last photo . Those and this thermostat mod see how it works. Hope it flows enough.

But wich reeds? Ccms or Boyesen? Have both.

7*c YES! Its summer!
