A southern facing position of your sunroom is preferred, however, east or west facing will be able to take advantage of the sun rising and setting.
During the Fall/Winter/Spring seasons, the sun stays low in the sky allowing free heat into the vertical walls of your solar collector sunroom. The “Heat Repellent” series roof glazing traps the solar heat in the upper area of the room.
A thru-the-wall fan placed high in the sunroom is added to the room design, along with a thermostat and seasonal shutoff switch.
The thermostat will automatically cycle the fan on when the sunroom temperature reaches about 75 degrees, delivering free heat to your home.
A separate sunroom zone heat source may also be installed with a lower temperature setting so you may also enjoy your sunroom addition on those cold winter nights.
