I've been thinking about the water filled barrels, but first thing I want to do is insulate the porch walls, ceiling and floor. I took some measurements last winter and with sunny sky and outside temp of 30°, it got up to about 65°F on the porch. The seven windows on the porch are removable (screens go on in the summer) and are old single pane glass.
Time for an energy audit. I'd rather waste gas in the Cobra as compared to wasting fuel
oil in a 80 year old house.
