Recordist's notes

due low temperatures a malfunction of the heating circuit caused air getting into the system. all radiators required bleeding in order to transfer heat again. opening small valve with a screwdriver. hissing sounds of escaping air, turning the valve to get different kinds of swishes and noises. all air released and pushed out with the water. turning the valve closed again. humming sound of the correctly operating radiator (roland r-04)
