From what I understand the pressure for hydronic radiant systems is about 12psi.
What is the reason for this being so low?
The pex pipe is rated much higher even at high temp.
Does it have anything to do with the supply to the boiler?
I have a tank less hot water heater system that is going to go into a heating box that supply's domestic hot water and the heating system, it is closed loop system with heat exchangers.
I plan to install a pressure regulator on the supply to the heating manifold after the heating box so the domestic hot water will still run at about 60psi while I can drop the pressure to the heating system.
