Now that the weather is getting cooler, have you realized that your water heater just isn't working right? Are you planning to have it replaced as soon as you are able to get the money to do so? While replacement can be costly, there's always the possibility that it doesn't actually need to be replaced. Instead, you may be able to have it repaired. A repair is going to cost you less money and could add years to the life of your water heater. Some of the things that could be wrong with your water heater but can be fixed with relative ease include the following.
In order to keep the temperature in the tank as constant as possible, there is a thermostat that triggers the heating process when the temperature drops below a certain temperature. If this thermostat becomes corroded or otherwise breaks, it may not be sending the right signals to the heating element. Fortunately, this is a relatively simple water heater repair for most units. The professional only needs to disconnect the old thermostat and put in a fresh one. Assuming that's the only thing wrong with your water heater, the entire process will likely take less than an hour.
Damaged heating element
The constant use and high temperatures involved mean that it's possible for the heating element itself to become damaged. If you have a gas water heater instead of electric, a damaged thermocouple could be the culprit rather than a broken thermostat. In either case, you're probably not getting any hot water at all whereas you might be getting slightly warmed water if you the issue is the thermostat. This is another water heater repair that is extremely easy for a professional. They may be in and out of your home so fast that you'll wonder if the thing was actually fixed.
Unless you have very soft and/or filtered water entering your water heater, you're going to get sediment buildup on the bottom of your water heater's tank over time. The more sediment there is, the less accurate the thermostat is going to be and the more likely it is that there will be loud banging sounds coming from your water heater when it is working. Draining the tank should flush the sediment out of the water heater. This should be done under the supervision of a water heater repair professional in case the tank starts to leak or something else needs to be done to get the water heater working again.
