basement baseboard heat question
for a 12 x 20 area in a basement that hovers around 62 degrees or higher, what length baseboard do you think I'd need to quickly warm the area to 70 or so when the kids go down? is it better to get a 240v wired in model or portable 120V model? What will this do to my electric bill? I see they sell regular baseboards and Hydronic baseboards whch cost 3X more and have some sort of fluid in them. Which is better and more economical?
