18°C feels varm outside but a little chilly inside
The temperature inside is about the same as outside. There are no or very little isolation in the walls. Last winter when it was 14-15°C outside, we had the same temperature inside. That feels coooold when you’ve had a shower or get out of bed in the morning!
It’s already started to be a little chilly inside, so now we have the gas heater in the livingroom and the electric heater in the study when we sit by the computer.
