It keeps the porch nice and warm even though it still loses quite a bit of heat through the windows.
My husband and I have been loving our heated porch lately. We always loved sitting out there during the summer months, but once October hit, it was too cold to sit out there. We got to where we really enjoyed sitting out there and drinking coffee in the mornings and evenings, so we decided to heat the porch area so that we could enjoy our time out there even during the cooler months of the year. It was not a simple task to heat the porch though. It took us quite a bit to figure out how to heat it. We put some insulation in the walls that did not have huge windows, but most of the walls had huge windows in them. It is made to be sort of a sunroom. I just love all the sunlight that comes in there. Because of all of the windows, there is quite a bit of heat that we lose in that room. We tried heating the porch with two electric space heaters, but they just could not keep up with the heat loss. We switched to propane a few weeks in, and it has done us well. It keeps the porch nice and warm even though it still loses quite a bit of heat through the windows. We hardly even notice a difference in the temperature from inside the house to the porch. It is nice and warm, and we are loving being able to be out there even in the colder weather. Hopefully, this solution will last because propane is nice and cheap to use.
