Fans? We put a large bank of windows on the south side of our house. Absolutely needed for both sunshine and day time passive heat, they are fantastic. On cloudy/rainy/snowy days it's cool sitting by them despite being triple pane with special coating for passive. Backwoods Savage schooled me on blowing cool air out of a back room instead of hot air in. This bank of windows that I sit next to almost all day is in the same room as the XL pellet stove, ~~15'. I could turn the stove up but I'd rather not bake out my family..... How to run fan to keep heat on me, temper the cold from the windows, and not turn this place into a sauna?
Getting the air to move quietly and slowly where you want it is key. I would try 2 of these... Orion (Knight Electronics, Inc.) - OA109AP-11-1TB - Terminals 3000RPM 47dBA 110CFM Sq 120x120x38mm 115V AC Fan - Allied Electronics They use next to no power, about the same as a night light. I'd try one up high near the ceiling (where the heat stalls) behind the stove and point it down and right at your desk area. The 2nd one, I'd put in the corner to your right and aim it directly across the large windows. It should do 2 things for you. Bring you warm air straight from the stove, and start a circulation of air in the entire room. If the air feels too cool blowing on you directly from the stove, you could try both fans in the corner moving air across those windows away from you (as Dennis said). The heat from the stove should then move your way as the air circulates around the room. If you can, get obstacles out of the air path. You'll need to adjust these ideas but it's where I'd start. Used these fans for years. They're common in Maine homes with woodstoves.
Cellular shades. They do wonders to keep the heat in the room. You can purchase them in single, double and triple depending on the heat loss of your window. We use these in our new bedroom, and they make a significant difference. On sunny days I open them to allow for passive heat. By 4pm this time of year, I close them to retain the passive heat gain from the day. When it's a cloudy day, I'll keep them closed as the solar gain is minimal on those days. Cellular shades comes in a wide variety of colors to include blackout for light or lighter colors to allow for some light even when closed.
