Natural gas heaters deliver a 30% higher First Hour Rating (FHR) than electric water heaters. A First Hour Rating is the amount of hot water per hour (in gallons) a heater can supply when starting with a full tank. So, because of the faster heater recovery and superior heat distribution of a natural gas water heater, you can relax and enjoy your shower without worrying about running out of hot water. Plus it works in storms and bad weather. For more information on natural gas water heaters, locate your local provider by clicking here.
