Furnace vs Boiler in Cheshire County, New Hampshire
When a furnace makes sense
If your house already has ductwork, a furnace is the simpler match. It heats the air and pushes it room to room through the same ducts, and with nine months of heating season here and nights averaging 15°F, you want a system that can recover a cold house quickly. The tradeoff is running cost, which comes in a bit higher than a boiler at New Hampshire gas prices.
When a boiler makes sense
If your home is heated by radiators or pipes in the floor, a boiler is the natural fit, since it heats water rather than air and has no ductwork to run through. It costs about 5% less to run than a furnace here, which adds up over nine months of winter. Retrofitting ducts just to run a furnace instead would work against the savings a furnace offers elsewhere.
