There are times when you may feel that your hot water in the shower does not last for a long time or even for your shower. This is a big problem. However this does not mean that you cannot tackle it. First, you need to see what temperature you have set your water heater in. In case it is not set on a high temperature, you will not be able to get the desirable amount of hot water. You need to adjust the temperature via using a dial that is present at the bottom of your water heater. This can be easily adjusted.

Rust can also be another reason that you are not able to enjoy hot water in your shower. It would be wise to deplete the heater of all the rust and sediment. This will make the water heater run well and give you enough hot water in the shower.
