The elements do not heat up at the same time. The top element heats the water first and then the bottom element kicks in.
Why do you need a thermostat for an electric water heater?
An obvious reason for interest in electric water heater thermostats is the temperature of your hot water. If you need to adjust the water temperature, the thermostat is the place to do it.
How to adjust water temperature?
To adjust the temperature of the water you need to get to the thermostats. These thermostats are a little harder to adjust than your furnace is. There are a couple of things you need to do to expose them.
What does the top element do in a water heater?
The top element heats the water first and then the bottom element kicks in . The upper thermostat acts as a coordinator between the two elements. When the water in the top part to the tank is hot enough, it lets the lower thermostat go into action.
Can a water heater thermostat be connected to a hot water tank?
Water heater thermostats are connected directly to the hot water tank. The tank will likely be hot. See the section on 'Cooling Down a Hot Water Tank' in the article ' Shutting Down an Electric Water Heater ' for information on lowering the water temperature in the tank.
Can you shut off the power to a water heater?
Before you test or work on electric water heater thermostats or the water heater in general, you want to make sure that you have shut off the power to the water heater. The electrical power that heats the water can cause serious injury or even death.
Is it hard to replace an electric water heater thermostat?
Replacing an electric water heater thermostat is not that hard of a job. You are dealing with some serious electricity and that adds a safety factor.
How does zoning work?
It involves multiple thermostats that are wired to a control panel, which operates dampers within the ductwork of your forced-air system. The thermostats constantly read the temperature of their specific zone, then open or close the dampers within the ductwork according to the thermostat's settings. Not only is system zoning helpful for houses with inconsistent room temperatures, but it's also great for heating or cooling individual bedrooms based on the desired temperature setting. If you have a usually empty guest room, just shut the door and close the damper.
What is the device that shuts off the heater?
Thermostats have another cool device called a heat anticipator. The heat anticipator shuts off the heater before the air inside the thermostat actually reaches the set temperature. Sometimes, parts of a house will reach the set temperature before the part of the house containing the thermostat does.
How does a talking thermostat work?
You simply say an activation word, such as "thermostat," followed by a command like "raise" or "lower," and the rest is automated. Talking thermostats are able to do this because they use DSP, or digital signal processors, to process audio and speech. First, the DSP filters out real-world analog signals. Then, the microprocessor changes them into digital signals. After the signals have been converted, they're sent through application-specific integrated circuits, or ASICS, and the thermostat reacts in real time.
What do the two transformers do on a thermostat?
The two transformers provide the power the thermostat uses to switch on the various relays. The relays in turn switch on the power to the fan and the air conditioner or furnace. Let's see how this power flows through the thermostat when the air conditioner is running. Advertisement.
