Currently, I am building a new house in Rhode Island. I love the look of a fireplace except I want it to be more efficient and keep my heating bill down. It will supplement my main source of heat- propane. I plan on building a traditional fireplace and purchasing an efficient insert. In a greenhorn when it comes to fireplace inserts. Does anyone have any idea of what kind of fireplace insert I should purchase? What would be a good model to heat a 1600 sq ft house? Any other ideas/thoughts are welcome.
