Hi. I’m installing new heating elements in a kitchen and need advice on installing. System is in its own zone. Will be running 8’ Runtal 6” baseboard and 2 Kickspace heaters. Runtal is 1/2” NPT so I assume use 1/2” hepex? Should I run through Kickspace heaters in series or Venturi tees? Should go through Kickspace then base or other direction? Thanks in advance
