I'm looking for options to heat a cabin located outside Seattle. The cabin is a one-story post-and-pier foundation structure with 2x4 framing. It is about 600 sq. ft. It is mostly not insulated. Current plan is to update windows and doors, and insulate the walls next spring or summer. But would like safe reliable heat to keep the place from freezing in the winter when we are not there. Don't have a closet or garage in which to install a forced air system. Is baseboard electric the way to go, or some other way?
The average daytime high temperature in Seatte is 47 F (Jan, Feb) and the average low is about 36 F (Jan, Feb). The alltime low is about 11 F (in 1989).
