faulty steam radiators? steam heat CPH?

well, you say enough knocking my brains out, but frankly, i’ve spent so much money on “heating assessments” and fixes by “heating experts” — to no avail! literally. the things that have actually helped AT ALL were things I ended up learning and doing myself, fixes that none of the heating experts who have come out ever even mentioned… At any rate, your advice, steam man, sounds good, so thanks.
