Soft solder could be weakened, particularly near the collectors, due to the high temperatures that occur there. Metal seal connections, locking ring fittings or Viessmann plug-in connections with double O-rings are the most suitable. If other seals such as flat gaskets are used, ade- quate glycol, pressure and temperature stability must be guaranteed by the manufacturer.
