Find your fireplace, from the Fundy coast to the Highlands.

Wrong question—and the industry's favorite way to confuse you. More BTUs isn't better if the fireplace cooks you out of the room you spent thousands to enjoy. Think in terms you can verify: how many square feet the unit heats, whether it's primary or backup heat, and whether you want it running overnight. Those three answers size a fireplace correctly every time.

In my own home, the room with the fireplace has never been the same—it became the social hub. Game nights, holidays, date nights after the kids are down: the fire is where the house gathers. There's a reason people in this industry joke that we're really in the romance and entertainment business. You won't wonder whether you'll use it; you'll wonder how the room worked before.

On average, a fireplace adds back to the home about the same amount you spent installing it. Add the monthly savings from heating the rooms you actually use instead of the whole house—often hundreds of dollars a year—and the value case is strong before you even count what a fire does for how your family uses the room.

If you're putting a fire in your house on purpose, it's best to work with an expert. Unless you're genuinely experienced in framing, gas line, vent pipe, and the national code on clearances to combustibles, have a professional do it—and ideally the same company that sells you the fireplace, so warranty, service, and liability all live under one roof.
