    Is your circulator running? If so check your tstat wire maybe it's pinched causing the pump to run. Post some pics of the boiler too maybe something will jump out.

    There was an error rendering this rich post.

    a flowcheck issue, or if zoned with Z/V's, it is either open or needs internal parts. Pics and more info please
