Saribelen and Bezirgan are both terribly cold and wet in the winter. I lived in Saribelen so I do know! Most of the locals who have houses there only use them as summer homes and retreat to the coastal areas for the winter. In the time we lived there (2008 -2012) even sawn logs were not available for the log-burner, which was the only form of heat apart from electric which was off a lot of the time, so we had a lorry load of felled trees delivered and had to chainsaw them into manageable sizes. That did help to keep us warm! We only put up with one winter there. We also had a summer house in Gömbe near Elmali before that and we had diesel central heating there. Beautifully warm but as the diesel was the same as used in the car it was prohibitively expensive to run so we only used it for the odd weekend in the winter when we could get through the metre and a half of snow! Most places away from the coastal planes are going to be expensive to heat although money is saved in the summer as aircon is not necessary.
