Hi, please give advice if you can. I am trying to find the best way to heat up a patio room that we've recently converted from a summer porch (all enclosed with screened windows and screen door) to a four season room with windows and a door. We are putting ceramic tile on the floor, we've finished putting pine on the ceiling but we don't know how to heat the room so that it is at least 50 degrees F in the winter, and can be adjusted quickly if we want to use the room to 70 degrees. We don't want to use the under the floor water method, but we are considering a stove or fireplace or ???..we'd appreciate any advice we can get.

Thanks!
