What is Positive Pressure?

More Efficient Heat Gathering and Distribution

This type of fireplace system is used to push heat more evenly throughout a home as well as replace any air lost in the combustion process. One of the unique features of this fireplace is that it uses outside air for both heating and combustion.

The blower system on these fireplaces forces fresh outside air through an efficient heat exchanger located around the fireplace and on into the home. By heating this outside air and forcing it gently into the home several benefits are realized. Heat produced by the fireplace is distributed more evenly, temperatures are more uniform, and the increased air pressure in the home reduces drafts coming in through the leaks and cracks of the home. The Positive Pressure fireplace system is considered by many to be the most efficient heat gathering and distribution system available today.

How the Alpine Positive Pressure Gas Fireplace Works

An Alpine Gas Fireplace brings in fresh outside air, circulates it around five sides of the firebox to gather maximum heat, and then gently pushes this heated air into the home at hearth level. A small portion of the air enters the firebox itself for combustion, leaving through the chimney with the other exhaust gases; the rest builds up a positive air pressure throughout the home. The warm air flows through the home and to the outside, through the same openings and leaks that otherwise cause drafts. You can usually direct more heat to a given area by opening a window slightly in the desired area, and letting the Alpine’s positive pressure fireplace push more soothing, warm heat in that direction. An Alpine Gas Fireplace is the fireplace you’ll really cherish and use regularly.
