Standard tank type water heaters usually last between 7 and 12 years. Tankless water heaters are expected to last at least 30 years. If its time to replace your water heater it might be a good time to upgrade to a tankless water heater which provides an endless supply of hot water on demand and uses less energy.

Water heaters can have all sorts of problems. Perhaps the pilot light on your gas water heater is out or not staying lit? Do you not have as much hot water as you used to have? These are a few examples of issues that can be resolved without replacement.
