<p>The invention relates to apparatuses for heating rooms with natural circulation of a fluid heat-transfer agent. The heating system with natural circulation comprises the following, connected by pipes: a heat generator, which is connected to an expansion tank by a pipe removing heated working medium, and at least one heating appliance, which is connected at one end to a pipe feeding in the heated working medium and at the other end to a pipe removing cooled working medium, which pipe is connected to the heat generator, wherein the expansion tank is connected to the pipe feeding the heated working medium to the heating appliance and is equipped with a tube with a float, said tube being arranged in the expansion tank and being hermetically connected in a vertically movable manner to the pipe removing the heated working medium from the heat generator, wherein an outlet opening of the tube is arranged above the level of the working medium. Feeding the heated working medium to the heating appliance via the expansion tank increases the efficiency of the heating system.</p> |
