I have a Regency insert that is freestanding on my hearth in a 1000 Sq. Ft Family room and a Pellet stove on the other end of my house in the dining room. The two rooms are connected via a long 28’ hallway with 4 bedrooms off the hall. I wish I could post a diagram, but I am not that intelligent. The Regency heats the 25’ X 25’ family room with 14’ vaulted ceilings to 75 to 78 degrees with little difficulties. I mounted a corner fan at the entrance to the hall and can blow the heat the length of the hall and some travels into the bedrooms. I can keep the bedrooms at 65 to 68 degrees when the outside air temp stays above 30 degrees. The Dining room stays around 60 to 62 degrees. As the outside temperature drops below 30, I fire the pellet stove up in the mornings (kids getting ready for school) and again before bed. With the pellet stove and the Regency running the bedrooms heat up to 72 to 74 degrees. I run my pellet stove at the lowest setting and use 40 pounds every other day. When the outside temp drop into the single digits I turn the pellet stove up one notch. This set-up has worked great for me and keeps the wife and kids nice and toasty warm.
