How much heat do we need from our fireplace?

A prospective gas appliance can be properly sized or “qualified” to your home based on many variables. Some, but not all of them, would be the size of the area, measured in cubic feet.  How cold is your climate? Is your home well insulated? Are you locating to a basement, or cooler area? Are there vaulted ceilings and ceiling fans, and so on. Many variables determine the correct amount of heat for an area or new home, and a local dealer can work with you, firsthand, to properly size the appliance.
