Zvuky Prahy / Sounds of Prague

Sound of the water heater Mora in my home at Resslova 1. Interestingly it created these sounds always when we had some visitors in the house - freaking them out with its merciless roar. Following that it stopped functioning as if it tried to draw our attention. So, that's how our communication started. Sometimes I have a strong feeling that it tries to interact with the boats cruising Vltava.
