Your household probably has a set morning shower routine. If you had the right size water heater installed, then you shouldn’t run into problems with the hot water vanishing before all your household gets their showers. But what if one day this ceases to be the case, and you have family members getting stuck with a lukewarm or even cold shower?
This usually means something is wrong with your water heater. It either needs to have repairs done or it needs to be replaced.
We’ll take a look at some of the reasons you have a water heater that isn’t delivering its expected volume of hot water. This isn’t an exhaustive list, but it covers frequent sources of this problem.
The water heater is too old and it’s starting to fail
We’ll begin with the most extreme case, but it’s one of the most common reasons for the “not enough hot water” dilemma. Like any heating system, a water heater will wear down with use over time and start to lose efficiency and then effectiveness. Regular maintenance slows this down, but when you have a gas water heater that is more than 20 years old, it has a high chance of losing its ability to heat up a sufficient water supply. Although gas water heaters can sometimes reach 30 years, we recommend replacing a water heater older than 20 years if it’s showing signs of struggling. (Electric water heaters can last a bit longer, on average.)
A malfunctioning aquastat
Aquastat is another name for the thermostat that regulates the water temperature in a water heater. Most of the time you won’t need to worry about it, because it can stay at the same temperature for years. (In fact, tampering it may lead to an accidental scalding hazard.) But if the aquastat malfunctions, it may not keep the water heater running long enough to give you enough for your needs. You’ll need pros to repair this.
A broken dip tube
The dip tube is the component of the water heater that carries fresh, cold water down through the tank and to the bottom, where it is heated up and then rises to the top of the tank. If the dip tube breaks, cold water will be deposited at the top of the tank, mixing with the hot water and lowering the temperature of the water. The water heater will quickly deplete the hot water at the top and start drawing in lukewarm and then cold water.
A failed heating element
This one is specific to electric water heaters, which use two heating elements inside the tank to warm the water. If one of the elements burns out, it will mean water is heated up much slower—and you’ll have your hot water supply drained faster. Technicians will need to drain the tank and replace the broken heating element.
