Are Water Heater Elements Universal
No, there are a few key characteristics that will need your attention. You need the voltage and wattage to match . As general rules of thumb, you always need to keep the volts the same, but you can install an element with fewer watts, just not more. Check the label on your water heater for this information. Some tanks have different wattage for each element, so be aware of that. If you have a 20-140 gallon tank, you probably need 240v and 4500 watts.
There are two configuration types: screw-in and bolt-in. Bolt-in elements are hard to find these days, and if you have a tank configured for a bolt-in element, then you can use a screw-in adapter kit.
Cost To Replace A Tankless Heat Exchanger
Tankless heat exchanger replacement costs $600 to $700 for labor alone or $1,200 to $1,300 for the part plus labor. Manufacturer warranties cover labor for 1 year and parts for 5 to 12 years, depending on the brand. The heat exchanger transfers heat energy from gas or electricity to water flowing past it.

Why Does My Water Heater Element Keep Going Bad
Dealing with a damaged water heater is a frustrating experience, especially if youre getting ready to hop in the shower or prepare a meal. When the water coming through your faucets is cold, the water heater is usually to blame. It could be the heating element in the unit, which can give out and require replacement. However, if your water heater element continues to go bad, its important to know what might be causing this ongoing issue.
Turn Off The Power And Water
If you have not already done so, turn off power to the electric water heater at the main power panel by turning off the circuit breaker or fuse powering the heater .
Turn off the cold water supply delivering water to the water heater. This shut-off valve is usually found just above the water heater, on the cold-water pipe that enters the water heater.

Putting In The Next Heating Element
Now that youve removed the current heating element, its time to put in the new one. When you were removing the old one, you probably encountered the rubber gasketor, at least, what remained of it after years of use. Go ahead and position the gasket so that it forms a tight seal between the element and the tank.
Running your water heater element wrench clockwise, install the new heating element. We recommend you start by hand-tightening it, and then using the wrench to tighten it just a little further. You need to find a happy medium here: you dont want to overtighten , but you also dont want the element to be too loose, which can result in leaks. Use your best judgment.

Checking Your Water Heater Heating Element
Before jumping in and changing your water heater heating element, you should check to see if the element is, in fact, the issue. It’s not uncommon to change the element, only to find out that the problem wasn’t the heating element at all.
To do this, first check to see if the circuit breaker has tripped or been accidentally turned off. If the breaker is fine, you’ll next need to check the reset button on the temperature cutoff. The reset button on a water heater is located above the thermostat inside the upper acccess panel. It’s typically a red button. Once you reset the button and the water heater trips again, the problem is most likely your heating element.
If you own a multimeter you can check the element for continuity. It’s very simple to do and the best way to know if your water heater’s heating element should be replaced. This short video takes you step-by-step through the process.

Check The Feed Supply
If you performed all the steps above but still no results then chances are the problem is with the main supply. Performing this test requires dealing with 240volts. If you arent comfortable with that then I advise calling the electrician and letting him do the job.
All right. So open access panel. Keep all connections intact. Resume the supply from the breaker. Get your multimeter, set it to voltage, and check the supply at the element. Is it 240 volt? If it is then the feed is good. Otherwise, theres the voltage drop at the feed of your home and you should call an electrician. Have you noticed your other electric appliance like dryer, electric oven not working? These are telltale signs of feed problem.
Pilot Light Replacement Or Lighting Cost
Water heater pilot light replacement costs $50 to $200. The pilot light produces a flame to ignite the gas burner. Plumbers charge$45 to $150 per hour to reignite the pilot light, and the task typically takes 1 hour or less.
If the pilot light doesn’t ignite, the problem may be due to a faulty thermocouple or gas control valve.

Electrical Testing Of The Elements
A bad element typically fails one or more tests with a continuity tester. Unplug the water heater, or turn off power to it at the homes main electrical panel before testing. Double-check that the power is off with a noncontact circuit tester. Remove the wires leading to each element, then test for continuity across the to terminals. If the testers light does not illuminate, the element is bad and youll have to replace it. You can also test for a short-circuited element by touching a probe to the terminal, and the other to the metal water heater tank jacket. If the light comes on, replace the element.
What Causes A Heating Element To Burn Out
Only electric water heaters rely on heating elements to warm up the water in the tank. A gas-powered unit has a burner at its base. If your water heater is electric, the element will come into direct contact with the water, which means items in the water could be causing the issue. However, the wiring to your electric water heater could also be to blame.
Heavy gauge wires provide electricity to the components of your unit, so a poor connection between the wires and the water heater could result in the element giving out. A wire that has slipped out of place or becomes damaged may also be problematic, and its important to get this issue checked out by a plumber as soon as possible. A hot wire could create a safety hazard, especially if it grounds through the metal tank.
Since an electric water heater is connected to an outlet in your home, a sudden surge of power can also cause damage to the heating element. Power surges can occur during electrical storms or if the power company suddenly experiences a surge on the other end. Every electrical water heater has a voltage rating, so exceeding that rating can burn out the heating element.
A water heater element doesnt work unless its fully submerged in water. If it did operate without any water in the tank, it could produce enough heat to burn out its core in a short period of time. The element must have water to transfer the heat in order to prevent significant damage.
