How Does a Fireplace Blower Increase Efficiency?

To understand just how a fireplace blower increases the efficiency of your fireplace, we must first understand how the convection process of a conventional gas fireplace works. Convection is a process in which heat is transferred through the circulation of a liquid or gas.  Easy enough - right?  Therefore, if we increase circulation, we increase the heat transfer process.

This is where the fireplace blower comes in.  A fireplace blower simply increases the circulation variable in our convection equation. As you can see from the diagram, your fireplace draws in cool air from your room.  This air is heated as it travels up and around the venting until it reaches the upper vent or louver. A blower forces the circulation of this air much faster, so rather than heated air trickling out of your fireplace, you get forced heated air instead.

Used in conjunction with an efficient home furnace and a couple of ceiling fans, you'll distribute warm air so efficiently in your home that savings hundreds of dollars a year in home heating costs will become common practice.
