Q: What is the average room temperature in an Icelandic home in the wintertime?
John, Fort Worth, Texas, USA
A: I asked around and as far as I could tell, there are no accurate numbers on the average temperature in Icelandic homes.
However, Reykjavík Energy has published a brochure on recommended room temperature: Bedroom 18-20°C (64-68°F); living room 20-22°C (68-72°F); bathroom 20-24°C (68-75°F); workspace 16-18°C (60-64°F).
Based on these figures, an employee at HS Orka (an energy company and heating utility in southwest Iceland), told me that the average temperature in Icelandic homes is probably around 20-22°C (68-72°F), yet pointing out that some people, the elderly, for example, want their homes warmer than others.
The brochure states that the inside temperature should not depend on the outside temperature, although I believe many people do turn the heat up when it gets colder outside and turn the heat off when the summer sun is shining through their windows.
