Heatilator fireplaces, also known as Old-style zero clearance fireplaces, are a combination of heater and ventilator and are by their nature, fireplaces that circulate air. Heatilator fireplaces use a special venting system that draws in cool room air and releases it as warmer air. The air that is in the venting system never goes through the firebox so it doesn’t get fouled with ash, smoke, or other unpleasant odors. Instead of pushing air through the firebox, Heatilator fireplaces route air around the firebox and allow it to heat, without any of the drawbacks associated with traditional fireplaces. This turns your fireplace into an 85% efficient heating source.
Old-style Heatilator Fireplaces are constructed with a double walled fireplace that keeps the heat where it belongs. Since the fire is kept in the fireplace chamber itself, Heatilators are able to avoid the transfer of excess heat into the walls of the home. This is an important safety feature because over time, excess heat transfer can accelerate the degradation of building materials.
