Here the recommended temperature range for bedrooms you tend to find is 15°-18°C iirc, and 18°-22° for living rooms, though you can get the temperature higher with most radiators. I think of "room temperature" as 20°C. My parents kept it warmer than that (I think it was more like 23°/24° or something, it was really warm), and I'd like to have 20°C everywhere, but regulate more to 18°C in my bedroom. Which then gets slightly cooler at night through the automated system.
