I put up polycarbonate greenhouse panels on outside of the post on patio and porch and clear plastic on inside , sort of turned it into a greenhouse.
It can be cold out but if the sun is out you have to open door to get heat out of porch because it gets to hot this heats kitchen and dining room and up stairs if door is open to stairway. This is the only heat I have downstairs heat in daytime.
Great to know, Farmer Tim! Thanks for telling us about it!
