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...

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...

Good news: The expansion tank needs to be replaced. I used a tire gauge to check it, and water squirted out rather than air. I thought this might be a cheap job ($100 for parts and $100 for labor, maybe?) so I called two local plumbers. Both quotes were in the $500-600 range. Pricey! For...

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...

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...
