How many BTUs do I need if the fireplace is my backup heat source during power outages?
In Swannanoa, the rebuild is the moment to design in backup heat: size one gathering room at about 20,000 to 40,000 BTU and choose an appliance that lights without power. After the storm, central heat quit with the grid — millivolt or battery-backup gas, or wood, is what kept homes warm.
Build backup heat into the rebuild
A lot of Swannanoa is rebuilding and renovating after the storm, and that's exactly the moment to design in real backup heat rather than bolt it on later. If you're opening walls anyway, a sealed direct-vent gas unit — battery-backup ignition, no chimney required — goes in clean and sized to one gathering room at roughly 20,000 to 40,000 BTU. In a Grovemont home from the 1940s or 60s with an original masonry firebox, a sealed insert on a proper liner does the same job through the existing chimney.
The kind of heat that doesn't quit
The whole reason to add it: when the grid failed, a furnace or heat pump died and the households with a live wood or gas hearth were the ones that stayed warm. Choose millivolt gas like the Valor H5, Napoleon's battery-backup line, or EPA-certified wood — all keep heating with the power out. Swannanoa is on the natural-gas mains, so most homes tie straight in on a licensed, permitted, pressure-tested line, which is our lane and no one else's.
River damp, and the permit
River-valley fog, cold-air pooling, and damp air are hard on masonry chimneys here, so a rebuild wants the flue and cap checked and the right liner fitted. We pull the Buncombe County permit and meet the inspector, and we're just 15 minutes east of the showroom. Call (828) 545-0525.
