Please note: The water heater elements, thermostats and other electrical products shown on this page are non-returnable.

How do I determine which type of water heater element I need?
  1. Examine your existing element.
  2. You will need to find out the voltage and the wattage. This information can usually be found on the label affixed to the side of your water heater tank.
  3. Compare and match your results of volts and watts to the volts and watts columns below.
  4. Choose the volts that match your voltage 120 or 240.
  5. Choose the watts that are closest to your wattage. (Note: if your wattage is not shown then use the closest wattage that is lower than your wattage. The wiring of your water heater may not be made to take higher wattage.)
  6. Make sure the tank diameter of your water heater will accommodate the element you've chosen.
  7. Consider your water quality - ripple style or foldback style elements are especially useful for those with hard water. These elements function the same and have the same voltage/wattage, but the greater surface area causes less wear on the element.
How do I choose which density I need?
  • Good = High Watt Density - made of copper tubing with magnesium oxide and nickel plating. Threaded base made of zinc-plated carbon steel.
  • Better = Low Watt Density - also made of copper tubing with magnesium oxide and nickel plating. Threaded base made of zinc-plated carbon steel.
  • Best = Ultra Low Watt Density - made from high grade Nickel and Chromium Incoloy (stainless steel). Threaded base made of nickel plated steel. Ultra Low Watt Density elements are recommended when water has high mineral content.

Frequently Asked Questions

Q. "Do you sell thermostats that will go to higher temperatures than my standard residential thermostat that came with my electric water heater?"
A. We aren't aware of any water heater company that will not void your warranty if you install a higher temperature thermostat. This is for two reasons: the lining of your residential tank probably isn't designed for continuous temperatures over 140 degrees and scalding liability potential. For that reason we also won't sell any electric thermostats that can go over standard temperatures.

Q. "Can I increase the wattage to a higher wattage when replacing an element?"
A. Due to liability, we never recommend that you increase the element wattage over the original element installed by the manufacturer. We are not aware of any water heater manufacturer that will warranty a heater if you have changed wattages.

Q. "What is the difference between High and Low Density elements?"
A. A high density element is able to transfer more energy flow (higher temperature) per square inch to the water in the water heater but these higher temperatures will wear out the element much quicker than a lower density element. If you have scale build-up a high density element will need to generate this higher temperature for a longer length of time to transfer energy through the added coating on the element which will then cause it to burn out quicker. Lower density elements operate at lower temperatures per square inch so if they encounter a scale build up, the higher amount of energy needed to get through the added coating does not cause the element to get hot enough to burn out the element. A lower density element tends to last longer.

Q. "Which is better, one element or two on a water heater?"
A. In our opinion, there is NO doubt about which is best: two elements! Most two element systems work like this: The upper element goes on first and once it is hot enough on top then the lower element goes on. If the water you are getting out of your heater comes from the top, why would anyone think that heating the bottom only is better? We think the only reason is to save manufacturing costs.

Q. "Do you think electric water-heater timers are worth it?"
A. In almost all cases we believe that they should pay for themselves in a short time.

Q. "What does incoloy mean?"
A. Incoloy is a type of extra high-grade stainless steel that helps extend the life of the element, resists burnout and the effects of sand or lime over time. For these elements, incoloy pertains to the element coil, not the threaded base of the elements. The extra low density heating elements are made of incoloy, the threaded base is stainless steel with chromium plating. The normal low density and the high density elements are non-incoloy. Non-incoloy element coils are copper on the inside with a nickel plating on the outside. The threaded bases for the low and high density elements are made of zinc-plated carbon steel.

Q. "I have an electric water heater that isn't working?"
A. For a water heater to work, you need the following:
1) Water in the tank; 2) Electric power to your heater; 3) Thermostats that work; 4) Elements that work.

Q. "I replaced the thermostat in my Tiny Titan water heater. As soon as I turn the unit on it shuts off after being on for just a few minutes. Is my new thermostat defective?"
A. Most likely not. If the heating element has become encrusted with scale or lime or if the anode rod is deteriorated and is no longer working correctly, then either one of these conditions can cause the liner of the heater to over heat which in turn causes the thermostat to shut off. The thermostat is equipped with a thermal cut off switch. You will need to push the reset button to reset the thermostat after the problem has been corrected. Unplug the power cord to the water heater and remove the front cover. Press the reset button firmly with the tip of a ball point pin, extra small screwdriver or similar object. A click indicates the thermostat has been reset. Reconnect the power plug. Now check the operation of the thermostat. Turn the temperature dial from high to low. If the red light does not go off on the low setting, disconnect the power supply and replace the thermostat. If the red light goes off on the low setting then set the dial to the desired setting and replace the cover plate. Note: If the heating element is not corroded and working correctly but the high limit needs to be reset frequently then call an electrical technician for further electrical diagnosis.

Q. "How do I check an electric water heater element? Should the elements be removed to check it, and do I need to drain the tank?"
A. It isn't necessary to remove the elements or drain the tank to test them, but the elements must be removed (and the tank drained) to replace them. To test the elements, you will need a voltage/OHM meter. Turn off the power to the heater first and disconnect the two wires to the elements. Set the meter to the "OHM" function, and check the flow between the two screw connectors of the elements: If there is a positive reading, then the circuit is "closed" and the element is fine; if there is no reading, the circuit is "open" and a new element is needed. Also, if you get a reading on your meter between either of the screw connections and the metal element, the element is shorted and must be replaced.
You should expect an approximation of the following readings on the OHM meter (give or take a little) for functioning elements:

  • 15.5 ohms for 3500 watts
  • 13.0 ohms for 4500 watts
  • 10.0 ohms for 5500 watts

Q. "Will 'low density' water heater elements take longer to heat up than 'high density' elements?"
A. No. Low density water heater elements use less watts of energy per square inch so they are made longer in length to make up the watts rating of the element. A 4500 watt high density element generally has 30 square inches of surface area and a 4500 watt low density element generally has 60 square inches of surface area.

Q. "Will the model #120-1500-ULWD water heater element work as a replacement for the InSinkErator model #W152-1?"
A. Yes, according to InSinkErator, our model #120-1500-ULWD will work as a replacement heating element for their model #W152-1 point of use water heater.
