Water heater maintenance is an important step to keep your natural gas bill under control. Although heaters that run on natural gas use less energy and are more cost-effective than electric water heaters, they aren’t necessarily problem-free. High gas bills could still be a concern if you don’t maintain your water heater properly.
Water heaters account for approximately 17% of your total household energy expenditure, according to Energy.gov. That’s why it’s important to understand how gas water heaters work and how to maintain them.
