5 Reasons Why You Are 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 it’s a problem. If you’re not getting enough hot water out of your hot water heater, there can be a few different reasons. Here are five reasons it may be happening.

5 Reasons Why You Are Not Getting Enough Hot Water


Sediment in your tank can be a sign of a more serious issue, and create problems with the hot water coming out of the tank. Over time, and especially in areas with hard water, minerals can build up at the bottom of the tank, and prevent the water from being heated properly. One way to deal with this issue is to drain your tank annually, clearing out the sediment. Rust in your water, however, is a sign of corrosion. That means you’re probably going to need a new heater sooner than later. 


A thermostat on your hot water heater controls the temperature in the tank. If it’s not getting hot enough, you can try and turn up the temperature. Make sure not to go past 140 degrees, however, as the water can scald at that point. If there’s an issue with the thermostat, that may also be the reason you’re not getting enough hot water. A licensed plumber may have to inspect the thermostat, to make sure it’s working properly. 

Small Water Heater

Another reason you may not be getting enough hot water is that the hot water heater you have is too small for your house or your needs. This may be the case if you installed the water heater yourself. It’s best to consult a professional to determine what size is needed for your home. In fact, some tankless systems now offer constant hot water. 

Dip Tube

Water is supplied to your hot water tank through a plastic tube that runs down to the bottom of the tank, preventing the cold supply water from mixing with the hot water at the top of the tank. If this tube breaks or falls off, the cold water may mix with the hot water at the top, cooling it off substantially. 


If you’re doing several things at once that all require hot water, chances are that you’re going to run out of it. For this reason, it’s best to run things like dishwashers and washing machines at times when people aren’t showering or bathing.
