Thinking of getting air conditioning for a flat abroad, where you can get 40 degrees in the summer and minus in the winter It's a small 2 bed apartment, 4 floors up. The unit would need to give out chilled air and heat. It's rented out occasionally to family and friends. I don't want the usual water output to a bucket on the balcony, as people, whoever well-intentioned, do forget to empty them, sometimes twice a day in the height of summer. Any thoughts?
