Warmth for St. Augustinus`church in Saarbrücken

Interview with Father Vogt and Ronny Havener:
"The seat cushion heating system represents a manageable financial investment, which was also gladly subsidised by the diocese and the European climate fund, and has thus brought us a significant reduction in energy costs. So enormous, in fact, that even our energy supplier was surprised and contacted us", Father Vogt reports.  (full video interview).
