A solar collector comprising a heat exchanger duct through which a heat transport liquid is conducted is arranged during operation at an angle relative to the horizontal. An upper portion of this heat transport liquid duct thereby provides a gas collecting reservoir, downstream whereof such duct is formed with a constriction in which a lower pressure prevails. An exhaust duct is in open communication between the gas collecting reservoir and such constriction and removes gas from the reservoir by the passage of the heat transport liquid through the constriction due to the resulting Venturi effect.
