5 Reasons You're Not Getting Enough Hot Water

5 Reasons You’re Not Getting Enough Hot Water

It’s easy to take our hot water heaters for granted. It’s not something we think about until we go to turn on the hot water and it doesn’t come out. Then you have a problem. There are several reasons why you may not be getting enough hot water from your hot water heater. Here are five possibilities.


Sediment in your tank can indicate a more serious problem and cause problems with the hot water coming out of the tank. Minerals can accumulate at the bottom of the tank over time, especially in locations with hard water, and prevent the water from being heated effectively. One solution is to dump your tank once a year to remove the silt. However, rust in your water is an indication of deterioration. That indicates you’ll probably need a new heater sooner rather than later.


The temperature in the tank is controlled by a thermostat on your hot water heater. If it’s not getting hot enough, try raising the temperature. However, do not exceed 140 degrees, as the water might scorch at that temperature. If you don’t have enough hot water, it could be due to a thermostat malfunction. A licensed plumber may be required to inspect the thermostat to ensure that it is functioning properly.

Small Water Heater

Another reason you may not be getting enough hot water is if your hot water heater is too small for your home or needs. This could be the situation if you installed the water heater yourself. It is best to consult an expert to decide what size is required for your home. In fact, some tankless systems now provide continuous hot water.

Dip Tube

Water is fed to your hot water tank via a plastic tube that runs down to the bottom of the tank, preventing cold supply water from mingling with hot water at the tank’s top. If this tube breaks or falls off, the cold water at the bottom may mingle with the hot water at the top, significantly cooling it.


If you’re doing numerous things at once that all demand hot water, you’re bound to run out. As a result, it’s ideal to run dishwashers and washing machines while no one is showering or bathing.
