gas home heater has lower operational costs because gas is usually cheaper than electricity and gas heaters are better at warming up larger spaces. gas heaters are best for heating larger, well-ventilated areas such as a garage or areas outside the house. The two basic types of gas heaters are vented and unvented. gas heaters are meant to be located next to a wall with a vent installed in the wall or ceiling that directs exhaust gases outside. Look for vented heaters labeled as “100 percent outdoor air” units, which are the safest.
