If your water heater may be going out, then you want to have it looked at right away so you don't get caught without any hot water all of a sudden when you really need it. If it does need to be replaced, then you should think about having it replaced by a tankless water heater. Below are some signs a water heater may need to be replaced, as well as reasons why a tankless one might be a good idea.
You have rust in your water
If you are noticing that the hot water is coming out rusty, then this could mean that the water heater is rusty on the inside. If your water heater does have rust on the inside, then you can also have more big problems ahead of you because it will likely start to leak soon. Rust will eat away at the metal, and once it has done so enough for there to be a small leak, you can very quickly end up with a huge leak that causes water damage and other damages to parts of your home and even some of your belongings. This is why rust in the water is a reason to have the water heater looked at as soon as you are able to get someone out. A rusting water heater needs to quickly be replaced.
Your water heater is very noisy
When your water heater makes some noises that sound like banging and rumbling, having it drained and refilled can take care of the issue because it flushes the sediment out. However, if it still makes this noise even though you have had it drained and refilled, then there may have been so much sediment buildup in it that it will continue to be a problem, and at this point, the water heater can end up with damages that can lead to a number of leaks and more problems.
You should be aware of the features a tankless water heater offers
If you need a new water heater, you may want to replace yours with the same type, if you have always been happy with it. However, consider whether a tankless one may improve your water-heater-related situation by thinking about some of the features this type offers, which include:
Water will be heated as you need it: With a tankless water heater, the hot water gets heated while there is a demand for it. This means there will be as much hot water as what's needed in the house for as long as it is needed. This means no more running out of hot water before everyone has had a chance to enjoy a warm shower. It also means a good amount of savings on your bills.
A big tank won't be taking up space: When you go with a tankless water heater, you will also have that space back that was used up by the large tank before. You will then be able to put the space to better use.
