Gas water heaters rate as an efficient and environmentally conscious way to heat water in the home. They also rank as the most common type of household water heater, according to Chilipepper Appliance of Sparks, Nevada.
How They Work
Gas heaters operate on gas piped directly into them, making secure mounting a priority. At the bottom of the heater, directly beneath the tank of water, sit the gas burners. A thermostat, also located at or near the bottom, controls the heat.
Fire Hazard
Because of the amount of heat generated by the water heater, its tank should not come in contact with combustible material, warns the American Water Heaters website. Most heaters utilize a stand, but some owners install a fireproof panel on the floor on which the tank rests.
Considerations
As a cost-effective method of heating and cooking, natural gas also burns cleanly, especially when compared to other fossil fuels, reports NaturalGas.org. Avoid storing flammable materials near gas heaters, warns AmericanWaterHeater.com.
