Differences between electric and gas heaters include costs, installation and efficiency. Electric heaters are cheaper and easier to install. Gas heaters have lower operational costs and are more efficient at heating large areas.
The two types of electric heaters include radiant heaters and convection heaters. Although electric heaters cost less to install, these heaters cost more to operate than gas heaters. Electric heaters require a electrical outlet and take longer to warm up. Convection heaters are considered an energy-efficient alternative for heating various areas over short periods of time. Radiant heaters are called reflective heaters, and these devices produce heat by guiding infrared rays to a designated area to create warmth. Electric heaters are the safest option for enclosed areas and portable heating.
Gas heaters are generally used to heat large areas, and they cost about 50 percent less than their electric counterparts to operate. These heaters require a well-ventilated area and are typically used for areas outside the home. There are two types of gas heaters that include vented and unvented options. Unvented gas heaters can produce harmful gases such as carbon monoxide, and as a result, these heaters are only used outdoors. Vented gas heaters must be placed near a wall with a vent installed or near a ceiling that guides exhaust gas outdoors. Gas heaters may require a chimney and a professional for installation purposes.
