Installing gas heaters is more difficult than installing electric heaters as a result of the chimney, air vents and ducts. Gas heaters require specialized tools and technical skills to install the chimney, which helps expel emissions from burning gases. Installation also requires vents and air ducts placed throughout the home.
Gas heaters are typically larger than electric heaters and require professional installation. Most portable electric heaters do not require installation, however, wall-mounted electric heaters must be installed. Although wall-mounted electric heaters require installation, the process is easier and less extensive than gas heaters. For this reason, the cost of installation for gas heaters is more expensive than electric heaters.
