Translation of Wärmepumpe

I found the idea of having two health care systems disgusting. We entered the rooms of the local hospital and the images there were horrifying. I don't know why he took me there until this day.
The bus was supposed to leave at around 4 o'clock in the afternoon, so that I still had two to three hours to organize. I went for lunch at some strange place and hardly ate as it was too ugly.
The room had around 4 square meters and the bathroom and shower were tiny. I was not content about that, as we could have stayed in a much better hotel for less. But we had made reservations in advance anyway.
