what do I check when one of my zones going out is to hot to touch but the return is cold this zone has 10 base board radiators hooked to it we have been using this for about 9 years when I drain 1st radiator water coming out is about 160 degrees it drops a little to every radiator by the time I get to the 5th one I'm lucky to see 100 degrees temp this always has worked in the past was told air in the lines but when bleeding we don't hear any. Please any ideas would help cant afford a heating contractor at this time thanks so much Kim
