Gas Heaters

Yes, gas heaters are generally less expensive to operate than electric heaters. Natural gas costs less per unit of heat produced, meaning homeowners with gas heaters typically see lower monthly utility bills compared to those using electric heat. However, upfront installation costs can be higher if gas lines don't already exist in your home.

A well-maintained gas heater typically lasts between 15 and 25 years. However, it may be cost-effective to upgrade sooner, since modern systems can reach efficiencies of up to 98.5%, compared to just 56–70% for older units. Upgrading to a high-efficiency system can cut your fuel bills significantly.

Gas heaters come in several main types: central heating systems integrated into your home's ductwork, wall-mounted heaters ideal for single rooms, portable gas heaters for spaces without central heating, and outdoor gas heaters for patios. There are also vented and vent-free (ventless) options, with vent-free models typically covering 200 to 1,200 square feet.

Vented gas heaters are safe for indoor use as long as they are properly installed and exhausted to the outside. Vent-free gas heaters can also be used indoors but require sufficient fresh air and adequate room size, since they need oxygen to operate properly. Gas patio heaters, however, should only be used outdoors in open spaces with plenty of airflow.

A gas heater that keeps shutting off is often being used in too small a space, as vent-free appliances require sufficient oxygen to run safely. A pilot light that won't stay lit may be caused by dust buildup, low gas pressure, a dirty thermocouple, or being used at altitudes above 4,500 feet where the air is too thin. Regular cleaning every 2–3 months and an annual inspection by a qualified technician can prevent most of these issues.
