I have almost 1000 sq ft on main level with some doors, staircase is 40 ft from insert, 3 individual bedrooms to heat upstairs as well as a bathroom, what do you think is capable of handling this type of job? The heat really needs to travel through the floor of the upstairs. Please help me to have real expectations. I have a space heater with the montpelier in one side of the house. But now I may need a house heater to accomplish the rest...thank you all...
