Top best answers to the question «Why is my electric water heater getting too hot»

  • It may sound strange but one of the problems when your water heater malfunctions is that it can allow the water to get too hot. The reason this happens is because the thermostat on your water heater has malfunctioned and it is allowing the heating element to remain on at all times instead of cycling on and off as heat is needed.


Those who are looking for an answer to the question «Why is my electric water heater getting too hot?» often ask the following questions:

👉 Why isn't my electric water heater getting hot?

If your electric water heater isn’t getting hot, you may have a defective element. On most residential electric hot water heaters there will be both upper and lower heating elements. If you have no hot water at all, then the upper heating element would be the most probable cause.

👉 Why is my electric water heater not getting hot?

If an electric water heater is not producing hot water, it could be a simple problem like a blown fuse or tripped circuit breaker. Additionally, some electric water heaters have a circuit-style safety switch located near or on the thermostat.

👉 Is it worth getting a whole house water heater electric?

Dana Dorsett adds some particulars: a whole-house tankless draws more than 25,000 watts of electricity and needs a 150-amp, 240-volt breaker. The total electrical service for many houses is less than that, he adds. A typical tank-style water heater draws less than 5,000 watts, and it will have relatively low standby losses.

If your water heater is making hot water too hot all of a sudden, it's likely the result of the temperature setting being too high, a malfunctioning thermostat, high mineral content, or the pressure relief valve is blocked. Each of these issues can cause the water from the faucet to come out too hot.

If the water coming from your faucet is too hot and turning down the setting on the water heater thermostat has no effect, the problem is very likely a malfunctioning thermostat on your water heater. The TPR valve is there to release excess pressure from the water tank if the water gets too hot.

In terms of your hot water heater, hard water in your home plumbing will lead to calcium build-up on the inside of the tank. This, in turn, will interfere with your appliance’s ability to effectively heat the water and control the temperature, resulting in H2O that is suddenly too hot or too cold.

In electric heaters, the elements attract minerals from your water supply, which calcify on parts of your heater, including the heating elements. If this layer of calcification thickens and builds up without regular cleaning, it can cause the elements to overheat in an attempt to heat the water to the required temperature.

If your hot water appears to be getting too hot, you probably have a defective thermostat. The temperature of your hot water is regulated by this adjustable thermostat which normally has a range between 90 and 150 degrees Fahrenheit.
