Hello, We recently moved into a home with hydronic heat. It is a one story 1900 sq. ft. home. The pipe system was originally installed 21 years ago when the home was built and is a 2 pipe system with copper pipes. It is now heated by a Propane fired Weil-McLain HE II-5 Boiler that is about 7 years old. The home. We have had problems since we moved in. We noticed that some of the radiators were not working so we bled the air from them two days ago and they were working better but now they were colder again and we checked for air in one of them and the air was back again. One thing we noticed is that the pressure gauge the boiler reads about 9 psi. Were we supposed to add more water to the system when we did this? Is that too low of a pressure for this system and is that why there is air in the radiators and why it would return after bleeding the air? If so, what is the solution for this. I have more questions but will start with this one for now. Any advice will be appreciated. Thanks, Karen
