Abstract of the disclosure A vacuum glass tube type heat collector tube with a substantially straight, double cylindrical construction is closed at its initially open end with an end cap having two or more separate ports for heat transmitting medium. A solar system unit is made up of a center conduit with two separate medium passages and a plurality of such heat collector tubes combined in a rib like arrangement with a valve mechanism arranged at every junction of the center conduit with the tubes which instantly closes upon accidental breakage of the associated tube. Easy drainage of the medium releaves the tubes from breakage due to medium freezing and instant closing of the valve upon tube breakage enables free replacement of the broken tube without any interception to the normal operation of the remaining part of the unit.
