Heating a house....

Just as important as heating choice is insulation. Put in the maximum amount you can afford, especially in the ceiling. Heat transfer (BTUs) increases parabolically as the differential between warm and cold areas increases. You might want to consider orienting the house, if possible, to garner as much wintertime solar gain as possible. That is free heat on sunny days. Keep total window area as low as possible because windows transfer heat much more readily than insulated walls.
