Gas-Fired Tank Water Heaters

On a life-cycle basis, gas-fired tank water heaters are typically the least expensive means of heating water. One reason is that on a per-Btu basis, natural gas and propane are usually much less expensive than electricity; another is that tank water heaters of 100 gallons or less are mass produced and are less expensive than most other types of water heaters. In some instances, other water heater types—such as electric heaters—are a better choice. But if gas is available and the water heater is in a location where a gas vent can be installed, a gas-fired tank water heater will likely be the least expensive to own and operate.
