Q: We bought a 30-year-old home last August. After surviving one winter (barely), we need some sound advice. Our heating system consists of a standard fireplace and one gas wall heater located at the end of one hall. The house is approximately 1,100 square feet.

The fireplace does an adequate job if you’re in the living room and the wall furnace does an adequate job if you’re in the back room, but neither seem to keep our home comfortable. — Margie

We suggest that you consider a gas-fired, forced-air furnace. Unlike your current wall furnace, a forced-air furnace will distribute the heated air to all areas of the home via a comprehensive network of ducting. Typically, the heating contractor will design and lay out the heating system so as to maximize the efficiency of the unit as it relates to the size of the home.
