I just installed a new 80,000 BTU high efficiency furnace. Outdoor temperatures are in the mid-30s, and I'm heating a 2150 sq. ft. poorly insulated 100-year-old house. The furnace is heating the whole house fairly consistently, but when I come home from work at night, having set the heat at 60 degrees while I'm away, it takes about two or two and half hours of the furnace running constantly to lift the overall temperature of the house to 70. I only heated a small portion of the house with my previous furnace (I installed ductwork upstairs and in the back lower floor rooms along with the new furnace), so I don't have a frame of reference. Considering that I have no insulation in the walls and almost none in the attic, I'm wondering if it's to be expected that the furnace would have to work so hard to heat the place.
