    Boiler getting overpressurized -- reaches 30 PSI and PRV releases water

    Thanks Jim. Here's my quick math: House is at most 40' x 60', so perimeter is 200'. Suppose piping for each zone goes all the way around the perimeter of the house. 200' x 4 zones = 800'. Add extra footage for supply and return between the levels of the house, and I estimate 890' = 10,680...

    Boiler getting overpressurized -- reaches 30 PSI and PRV releases water

    Thanks for the helpful replies! At Tom's request, I've attached a photo of my boiler. Thanks for the suggestion -- I should have done that a while ago. Jim -- Yes, before I installed the new expansion tank, I used a bicycle pump to pump it to 18 PSI. It seems entirely possible that an...

    Replacing the expansion tank was more of an adventure than I expected. On top of the expansion tank are the air purger and air vent, with a small valve between them. I guess the valve was placed there to allow replacing the air vent without having to take the system pressure down to zero...

    Boiler getting overpressurized -- reaches 30 PSI and PRV releases water

    Thanks a lot for all the replies! The aquastat is wedged in between the boiler casing and the wall, so it was hard to get to. With a headlamp and a mirror, I can now see that the aquastat has a high temp setting that can range from 180 to 240 degrees. It was already set at the minimum, 180...

    Boiler getting overpressurized -- reaches 30 PSI and PRV releases water

    I just bought a house in August that has a boiler. I've never had a boiler before and what little I know, I've learned from reading the excellent posts on this forum, as well as a few other websites. I have a problem with pressure, and would really appreciate some help. Here's the brief...
