Water leaks are the most common problem with water heaters. In the long run, the water can corrode the tank and cause leaks.

Tankless water heaters need a separate gas line because of the pressure differences. They require more gas when it’s time to heat the water. They may use less energy overall but pull in a high pressure when heating is required.

Strange noises, insufficient hot water, foul odors, and old age may be signs that your water heater needs to be replaced immediately.

A tankless water heater can be installed in an old home, but certain electrical and plumbing modifications may be required to cater to the system. These upgrades may be necessary for installation and ensuring better water quality and pressure.
