Gas water heaters are central to many of the comforts of modern life. People are generally not eager to start looking at replacement gas water heaters, but it's important to know when the time has come. Folks who feel unsure about whether they should replace their water heaters ought to look for these five signs of problems.

Rusty Water

Discolored water is often a sign of trouble with the water tank. As the interior rusts, the material flakes into the water. The rust then dilutes and discolors the water.

Notably, rust can come from the lines and even the main water supply. However, you can usually eliminate those culprits by running only the hot water hard for about a minute. If the water remains discolored, the chances are high that the gas water heater is the source.

Leaks

Gas water heaters can develop leaks. Sometimes, the problem is at the lines or couplings. However, the leak could also be the tank itself. Especially if you're seeing puddles underneath the tank, the odds are high that replacing it is going to be the best option.

Be aware that the gas line can also leak. This is a dangerous condition. If you smell gas, turn all gas-based systems off immediately and as a contractor to check things out. It is better to be safe than sorry when it comes to a possible gas leak.

No or Little Heat

The system may also stop putting out hot water. It could happen suddenly or gradually. Especially if you're dealing with persistent problems with keeping the water heater lit, you should begin shopping for replacement gas water heaters.

Noises

Other than the sound of the gas burners, you shouldn't hear the heater very much. Particularly if the noise is audible on a different floor than where the heater is, something could be wrong. Ticking, thumping, popping, and groaning sounds are all bad.

While modern gas water heaters are designed to avoid explosive failures, there is still minimal risk. Even if the system doesn't blow up, it could still fail in a way that causes significant water damage. Replace the unit as promptly as possible.

Growing Gas Bill

Every system becomes more inefficient with time. People tolerate this because there's always a cost-benefit curve. At some point, though, the cost of paying for more gas will outpace the benefits of not replacing the water heater. Watch your gas bill for signs that the water heater is consuming too much energy.
