Herr F. Morina hat für meine über 50 Jahre alten Heizkörper, die sich nur noch teilweise erwärmten, eine finanziell annehmbare Lösung vorgeschlagen: Ersatz der verschiedenartigen Ventile durch einheitliche Schwerkraftventile mit Regelung. Er hat diese zum Teil schwierige Arbeit zu meiner vollen Zufriedenheit ausgeführt mit dem Resultat, dass das Wasser in allen Heizkörpern zirkuliert und die Wohnräume wieder wohlig erwärmt sind.
