Input the dimensions of the area to be heated, and how well your house is insulated and the Wood Stove BTU Calculator will display the recommended minimum size wood stove required to heat the area.
When calculating the size of the area to heat make sure you include all rooms that will be joined with open door ways. If it is expected that a door will be open then the area of that room should be included. If a stairway leads up stairs the entire area of all open areas needs to be considered when sizing the wood stove.
