A heating system for buildings comprises a storage tank (1) for accommodating a heating medium, preferably water, a heating means (14) connected to said storage tank, a plurality of radiators (2), a pipeline system (3, 4, 5) extending between said storage tank and radiators for conveying the heating medium, at least some of said radiators and/or a part of said pipeline system lying at a higher level than said storage tank (1), and a valve means (13, 13') disposed in said pipeline system (3) and adapted to vent said pipeline system and said radiators when these are filled with the heating medium. The pipeline system is closed and, during operation of said heating system, does not communicate with the surroundings, whereby said storage tank is not affected by any static excess pressure deriving from that part of the heating medium which is contained in those radiators and that part of said pipeline system which are above said storage tank. |
