I must assume that the element has burned out. When the element over fires and burns out, the metal becomes annealed. This means that it is soft. Just pull very firmly while working it back and forth until it bends enough to allow removal.

Hot water recover time


No.
Fold-back elements are low-watt-density, so element does not burn out as easily since heating is spread across more surface area. But recovery remains 16 gallon per hour.
20 amp breaker and 12 gauge wire: max 3800 watts
30 amp breaker and 10 gauge wire: max 5800 watt.
4500 watt element heats 20 gallons per hour.

Instead of changing elements: Set thermostats higher so more cold is added to hot water, and then you have more hot water available inside tank.

We just recently replaced both heating elements in our water heater. Now the water is just barely getting warm and not hot. What's wrong??


Electric water heater if fully repairable by homeowner:

A] First of all, we know your upper element is working because you have some hot water:
http://waterheatertimer.org/How-it-works.html
That says tank is not overheating.
It says tank is getting 240Volts.
It we know water heater is 240Volts because you have 2 elements.
And it says reset button is not tripped.

B] That leaves 4 suspects:
Suspect 1) Bad Upper thermostat or Bad Lower thermostat: solution replace both thermostats for about 25$. Steps shown in link below.
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html
Suspect 2) Burned out Lower element: solution take out element, clean sediment out of tank, put in new element. Steps shown in link below
http://waterheatertimer.org/How-to-clean-sediment-out-of-electric-water-heater.html
Suspect 3) Loose wire or connection: solution open covers and remove insulation and look for signs of burning and high heat. Tighten all screws very tight. Replace burned part. Put insulation and covers back over thermostat so thermostat not exposed to cool air which will cause thermostat to misread tank temperature.

C] Before replacing anything, you can test water heater parts and determine exact cause of problem. Testing requires $5 multimeter from Lowes or Home Depot:
Install battery in multimeter.
When test calls for testing voltage, rotate multimeter dial to 240 or 250 or 277 Volts.
When test calls for testing continuity, rotate multimeter dial to ohms (upside down horseshoe symbol is ohms)
http://waterheatertimer.org/How-to-troubleshoot-electric-water-heater.html
After doing 30 minutes of testing, you will be expert in water heaters.

D] You replaced elements for a reason
.
Did you test elements before replacing?
Was tank producing some hot water before you replaced elements?
If tank producing some hot water, then lower element was bad, and upper element was good.

And when you replaced lower element, did you also clean sediment out of tank?

If sediment builds up inside tank, it will reach lower element and burn out the element.
That could have been original problem, and it could be same problem again.
Restore full efficiency to tank by cleaning out sediment and replacing lower element.

What is the energy factor for the mod.82V80-2? I have two seperate 30amp circuits, one for the top element and one for the bottom element, if that changes anything.


http://www.rheem.com/product.aspx?id=09DF2BDD-5E11-4D32-B574-84ACFB8A4619
http://globalimageserver.com/fetchDocument.aspx?id=052c9e32-ce37-48d7-8990-9e430f23fef3

82V80-2 Energy factor is .86 according to water heater industry self-regulated standards.

Rheem pdf says these water heaters are wired for non-simultaneous operation.
Except special order water heaters.
Non-simultaneous operation uses single 240V circuit as described below.
If your water heater is wired for simultaneous operation, and each element is on a separate circuit, that makes your water heater special order. I would guess the reason is for higher first-hour delivery, which implies rapid heating and would likely affect energy factor.
You might want to get serial number off model and call Rheem for specs on that special order.

Your water heater energy factor may be the same because 'energy efficiency is based on the amount of hot water produced per unit of fuel consumed over a typical day.' This means an aircraft carrier can be considered highly efficient despite overall cost. And naturally the guys making the aircraft carrier are also doing the rating.
http://www.energysavers.gov/your_home/water_heating/index.cfm/mytopic=13000

Non simultaneous operation means the upper thermostat controls heating functions.
240V goes to upper thermostat first.
When water inside tank is cold, thermostat reads temperature through tank wall.
Upper thermostat turns on upper element until top 2/3 of tank reaches thermostat set point.
Once set point is reached, upper thermostat turns off upper element and sends power to lower thermostat and lower element.
Lower thermostat reads temperature through tank wall, and turns on lower element until bottom 1/3 of tank reaches thermostat set point.
As water cools inside tank, lower thermostat is first to respond since hot water rises.
Lower thermostat turns on lower element until tank again reaches set point.
When hot water faucet is turned on, hot water exits top of tank.
At same time, cold water enters bottom of tank through the dip tube.
The heating cycle repeats.
At all times, the electricity flows through upper thermostat. And upper thermostat is powered by one 240V circuit.

With simultaneous operation, the upper and lower thermostats work in same manner.
Except thermostats are wired separately.
Lower thermostat does not wait for upper part of tank to be heated first.
Lower thermostat turns on whenever lower part of tank cools.
The advantage is more hot water available rapidly when demand is high. This is called first hour recovery.

One method for reducing electric consumption is to set lower thermostat so it only turns on during certain times of day. For example Whirlpool Energy Smart operates in this manner and shaves a few bucks off the bill each month. This says that simultaneous operation is not an energy saver, unless that circuit controlling lower thermostat is set on a timer.

Sounds like a squirrel inside water heater


Hi,
The noise is inherent in electric hot water heaters. It is the noise that the water makes when it is being heated by electric heating elements. Mineral buildup on the elements can make it worse, so changing the elements can help...but will not totally elimenate the noise. When I install a new tank and turn it on all I have to do is listen to it to see if it is working or not...even brand new will make a sound...it is the sound of hot water... :-)

The water gets too hot and trips the reset on the thermostat.


Two possibilities. 1 failed upper or lower Tstat 2 Shorted element
To test element: disconnect both wires to element terminals. use continuity tester to see if there is continuity through element (one probe on each element terminal) If no continuity element is bad. Then test for continuity between each element terminal and the water heater itself.( one probe on element terminal and one probe grounded on bare metal or inner tank.) If there is continuity from terminal to ground, element is bad and also can cause tank to continue heating even when thermostat shuts off. This is because the thermostat only shuts off one pole of the 220 and a shorted element can continue heating from the 2nd pole.
If both elements test OK and water heater heats the full tank( tank feels hot at bottom element access panel when no hot water for 2 hours) most likely the lower thermostat is bad.

Water Too Hot


needs new thermostat(s) If the whole tank is heating( next time it trips, before using any hot water check the lower tank thru the lower element access(breaker off) If the lower tank is hot-you need a new lower thermostat. if just the upper part of the tank is heating -you need an upper thermostat.

Hot water tank - the hot water shuts off even though there is power to the device


The circuit breaker keeps getting thrown yes? Alright then, you may have a bad element inside the water tank. If you don't know what a circuit breaker is then please call a plumber and do not go near the water heater as it may be a danger to your well being. However, if you do know, then go out there and throw the breaker to the water heater. If you are not sure about this or can not test the voltage at the water heater then do not proceed. However if you are sure, then take off the little covers from the side of the tank and look at the insulation as it may appear moist or wet. There is a heating element inside the tank which can break off, cause electrical shortout and allow water to leak out into the insulation. How to Fix: Shut off the cold water supply at the top of the water heater, then go to the nearest sink and turn on the hot water. There should be no water pressure if you shut the supply valve going into the tank. Now then, leave the hot water turned on at the sink as this will provide a vent for draining the water from your water heater. At the water heater there is a small valve at the bottom which when opened will drain the entire volume of the tank. I suggest that you find and connect a hose to this valve prior to opening it so that the escaping water goes outside rather than on your floor or you could just call servpro and let er rip. Either way, while the tank is draining look on the side of the water heater and find out if it is 240vac or 120vac and write this down. Now look to find the wattage of your heating elements. It might be 1500 watts, 4500 watts or 5500 watts, write down the wattage indicated for the heating element you are about to replace. Write down the brand and the model number along with the voltage and element wattage and go to your local hardware store. Ask one of the older guys (not the kid in electronics) if they would help you select the proper heating element for your make/model and also ask if you need an element wrench to install the heating element which you are purchasing. If the answer is yes, then get that to as you will be needing one very soon. Back home your tank should have drained completely. Now on the face of the old element will be two wires; remove them. Take your nifty little element wrench that you just bought and remove the old element. You will probably be amazed to find that the old element is like, in two pieces, and that's because the rest of it has fallen off inside the tank. If you can retrieve the part left in the tank then do so however it will not be a problem if you can not. Disregard the white hard water build up inside of the tank unless you have the time and capacity to dig all of it out through that little hole. Although, you may need to wallow it out a tad so that the new heating element can fit inside. The new one will replace just as the old one was removed and do not over tighten (it just needs to be snug not twisted off). Replace the two wires; either way don't matter. Then shut the drain valve and open up the water supply on top. Your hot water tap in the nearest sink should still be turned on and now you should hear the air escaping from inside the water heater tank as it is being filled with acid. No just kidding, it is filling with cold water. When the tank is full, water will run from the tap and only then may you shut off the tap. Now with the tank full and the new heating element wired up to the thermostat you can throw the circuit breaker back on. Congrats. Within in 30 mins you will either have very hot water or you will hear an explosion louder than anything you have ever heard in your life. As long as you followed the filling the tank till the water runs out your faucet bit, you should be good to go; go take a bath that is.

I installed a now 40 gal. electric water heater, made by Reliance, problem: I have power going to the top thermostat and element, but there is no power going to the bottom element.please help, thanks Mike...


How they work. First you need to know that cold water goes into the tank near the bottom (because of the "dip tube" inside the tank) and hot water is taken out at the top. Also hot water naturally rises.
so... when the tank is full of cold water the top element will come on and heat up the top 1/3 of the water then the bottom element will come on and finish heating the rest of the tank.

so... set them both at the temperature you want the water to be... about 120^F.
