Early in the morning the temperature in the office is about 12ºC! As all our heating needs a human interface (solid fuel central heating, a solid fuel stove in the kitchen), I use a small electrical heater next to my desk. So that's why I am not starting work too early! Temperatures during the day vary: if it's sunny you can have lunch in the sun outside, if the fog stays on or or if it is just cloudy, it's best to stay next to a heater!
We have already had some 'heladas' (frost), having to scrape the ice off the car windscreens in the morning.
Most houses here are just heated with the solid fuel stove in the kitchen. That is also the only stove we keep on day and night. It keeps the house reasonably warm and dry.
