The thermostat is a thermistor that responds to heat by producing a small electric current. The current increases when water temperature increases, and drops when temperature drops. Changes in the electric current cause gas control to turn ON and OFF. When gas control turns ON, it releases gas to burner.
How does a smart water heater controller work?
This device simply turns the heater on, when the water is too cold and off again when the water reaches a predefined temperature. Smart water heaters, on the other hand, can do much more than that. They use the water temperature measurements together with your water consumption patterns or preset instructions.
How do I know if my water heater thermostat is bad?
If you turn the hot water tap and cold water runs out, then the upper thermostat is damaged. But if the water is hot that becomes later becomes cold, then you have a damaged lower thermostat.
What controls the water temperature in a water heater?
thermostat
The water heater’s thermostat controls the temperature of the water inside the tank. The recommended water temperature setting by most manufacturers is between 120 to 140 degrees Fahrenheit.
Why does a water heater have two thermostats?
An electric storage-tank-style water heater has two thermostats because it has two heating elements. The thermostats are designed so only one element is active at a time. The reason only one element is active at a time is because it allows for smaller wire sizes and lower amperage demand when in operation.
Why does a water heater need WiFi?
Remotely set the water heater to vacation mode, preventing it from heating and reheating water that’s not going to be used. The device can also save money and water by helping to avoid, or at least mitigate, disasters.
Is a smart hot water heater worth it?
The main benefit of smart water heaters is that they help you save big time on your energy costs. Heating water is often a big chunk of your energy spending, usually right behind your home heating and cooling expenses.These rest periods mean you can avoid paying for hot water when you don’t really need it.
How do you test a water heater thermostat?
Test the lower portion of the thermostat, by touching one lead to the common terminal (next to the temperature setting) and the second lead to the left heating element terminal. If the water in the tank is below the thermostat’s set temperature, the multimeter should read close to zero ohms of resistance.
Why do I have to keep resetting my water heater?
When your thermostat stops working correctly, it can fail to regulate the temperature in your electric water heater properly. This, in turn, will cause your water to heat up to dangerous levels, which will cause the reset switch to trip.

Oftentimes, water heaters will have additional options to either lower or increase the temperature of the water inside. In the case of the video’s water heater, A, B and C each have an increase of about 10 degrees.
Which element comes on first in a water heater?
The upper thermostat first sends electrical energy to the upper element until the water temperature in the upper third of the tank reaches the thermostat setting. Power is then transferred to the lower element until the remaining water reaches the lower thermostat setting.
Do both hot water heater elements come on at the same time?
Only one element will come on at any one time. This is known as a flip/flop system. On a 240 volt water heater, there will always be 120 volts to both elements.When the tank is full of cold water, the upper thermostat will take priority and heat up the top portion of the water to the setting of the thermostat.
Should both thermostats on water heater be set the same?
The majority of electric water heaters have two thermostats: an upper and a lower, located under two control panels. To ensure your electric water heater works as efficiently as possible, you should set both of the thermostats at the same temperature.
What is energy smart water heater?
The Energy Smart® electric water heater combines an electronic thermostat which replaces the conventional electromechanical ther- mostat, with an Energy Smart® module user interface. This user interface is simple, convenient, easy to access (no doors) and infor- mative.
