Many people often misunderstand fireplace blowers and fans. They are highly effective tools for better utilizing the warmth created by a fireplace and pushing warm air into the room's furthest reaches. Unlike a space heater, fireplace fans work on cycling the entire room's air and increasing the ambient temperature by cycling the air around the hot firebox. A fireplace blower pulls air in from the room and forces it through a channel on the fireplace's exterior. As the air travels around the hot fireplace, it heats up, and by the time it is released into the room, the air is much warmer than the rest of the room. Our Pleasant Hearth Vent-Free Fireplace Blower does precisely that. It is designed to maximize the heating efficiency of a fireplace, creating a warm atmosphere that's expelled into your home. It also features a manual and automatic mode for added convenience. For more information and queries regarding this product, please contact our online executives, and we'll be happy to help.
