Factors to consider heating with one ductless head per floor
Are there guidelines on how well a ductless head will perform based on square footage of area trying to cover? It seems like there is a lot more to it then heating load of the entire floor. Type of layout, volume of space, cfm of blower, thermostat location, ability of heat to go through doorways, oversizing of head, etc. Assuming insulated basement foundation walls, are the square footage limits on first floor living areas heated by one ductless head?
