Can a century home stay warm without having a fireplace installed?

Absolutely, a century home can stay warm without a fireplace by relying on original heating systems like coal furnaces and steam or hot-water radiators. These systems provide steady heat throughout the house without the inefficiencies of open hearths. Additionally, modern upgrades like high-efficiency wood stoves or direct-vent gas units integrated with period-appropriate mantels can enhance warmth and ambiance without relying on traditional fireplaces.
