My husband and I are in our 20\\\'s and never grew up with radiators. We bought a 97 year old house with a brand new boiler. We couldn\\\'t stand the weather anymore last night, so we turned up the thermastat. Ok, now there is heat from the radiators downstairs, but nothing upstairs. Do we have to do anything to the actual radiators or the actual boiler? We are so confused and there is no manual. Thanks in advance.
