Can you run a hot water heater on one element?

So, can you run a water heater with only one element? Yes, a water heater can still run if the bottom element quits. However, the water heater won’t run efficiently and likely won’t produce enough hot water to satisfy your family’s needs running on just the top element.

Can a top element be replaced on a water heater?

If the top element fails, you need to replace it with another top element. You wouldn’t be able to use an extra bottom element to replace a broken top element, as the two aren’t interchangeable. Most people will also change out the thermostat when the top heating element is replaced.

Can a top element be replaced with a bottom element?

Top elements and bottom elements are entirely different devices. You can’t replace a top element with one designed for use on the bottom, and vice versa. Ensure the wattage of the replacement element is lower than or equal to the wattage of your current element.

What do I need to know about my new thermostat?

You’ll need to identify if your home is fitted with 1 Stage, 2 Stage, Direct Line Voltage, 24mV, or Zone heating and cooling to determine which thermostat will be compatible. Your new thermostat will be labeled to show compatibility.

Is it bad to change the thermostat on a water heater?

It’s also not a bad idea to change the thermostats (even if they test good,) if you are changing the elements. In every water heater, there is a plastic dip tube that brings cold water to the bottom of the tank to be heated and prevents it from mixing with the already heated water at the top of the tank.

How does a water heater work with one element?

If the water temperature at the top of the tank is lower than the top thermostat’s temperature, then the top heating element will turn on and begin the warming process. Once the water at the top of the tank reaches the temperature indicated by the thermostat, the top element will turn off, and the bottom element will turn on.
