Immaculate 1930s house, lifting flooring not an option.
Open vent, gravity hot water.
Seeking to confirm suspicion of single pipe distribution to rads.
Observation. Turning heat on with rads half full and cold, venting air results in both pipes to rad immediately becoming hot.
Advice on any other test to confirm or disprove, appreciated.
