Home building tip #26: Zone your floor plan for efficient heating
Open floor plans look great in photos but heat inefficiently in Maine. A 25-foot vaulted great room loses heat to the ceiling, struggles to cool in summer, and means you're heating a large empty volume 24/7.
Smart zoning saves real money: keep main living areas reasonably sized and well-connected, but separate primary bedrooms, guest wings, and basement spaces with doors so each zone can be heated independently.
Pair this with multi-zone heat pumps or a hydronic system with multiple zones, and set bedrooms to 62°F at night and 68°F during the day. Plan ceiling fans (with reverse mode) in any room with ceilings over 9 feet to push warm air back down.
The layout decisions you make today control your heating bills and comfort for decades.
