Looking for a little clarification on the purpose of the pressure reducing valve on a water boiler
Hey guys. I’ve been on here in the past and learned enough through the forum and the lost art of steam heating book that I installed one boiler in my one house and repiped pretty much an entire 2 pipe steam system in the other. Well, now I’ve sold one of them and bought a new one that has a hydronic boiler. This house has well water and the pressure switch took a dump today which killed the pump and we had no water coming into the house. I was at work so I had the wife shut down the boiler because I was concerned that the system didn’t have the water pressure backing the system up through the pressure reducing valve. I’m not sure if this was even necessary but I went on the side of caution. Is it necessary to have the water pressure backing these systems up for them to operate normally ? Is there a book for hydronic systems I should buy ?
