Hi everyone!
I and my friends have just settled in Korea and are living in a very good housing unit in Seoul but we noticed that it doesn't have a heater fixed near the wall usually found in European housing units. We have an air-conditioning system to cool our rooms but we don't think it is good for the winter.
Any advise on what we should do in order not to suffer the freezing temperature in our unit during winter? Maybe the winter won't stay too long but we are still kind of worried and we wanted to be prepared earlier.
