Hi, I never had a boiler before. I just moved into a house with a peerless residential boiler. I had to put a new expansion tank on it. My question is, If I have my expansion tank set at 8 psi and my cold water pressure in my boiler set at 12 psi, when the boiler heats up to 200 degrees what would be normal for the inside boiler pressure to go up to? And I see a bottle next to the boiler of a corrosion additive to put inside the boiler to keep it nice inside. What do you think of these additives? Thanks.
