Boiler running...

Hello,
This is my first post, we moved into our Eichler on Gainsborough on Saturday. Our boiler is hot but the heat is not turned on. Is this normal? I am worried that there may be a leak in the system and that the boiler is filling. I have not had a chance to have a boiler man look over the system yet. Can anyone recommend a good inspector/service man. Send recommendations directly to poster at mchester AT berkeley DOT edu
Thanks,
Margaret
