A traditional Single Sided Fireplace can be viewed from the front and is one of the most common configurations for an indoor Fireplace. Direct Vent Fireplaces allow you to easily bring the warmth and comfort of a hearth fire to your home with or without a chimney. A specially designed coaxial piping system (a small pipe within a large pipe) allows pollutants to exit through the inner tube and air for combustion to enter through the outer tube. Because One Sided Direct Vent Fireplaces are closed combustion units, they are able to heat a room very efficiently with minimal heat-loss.
