Looking at some diagrams, it shows that it is. I wouldnt want it going off destroying the hardwood floors upstairs if there was any excess pressure. Thoughts ? Ideas ? Thank you.
The boiler must have a PRV on it, you could plumb the drain to the basement or possibly outside. I would advise a shield if you do so. If the DHW is off a tankless coil they both must have their own PRV at different ratings more than likely.
