SOURCE: I am trying to drain my electric water heater:

Hi Karen, think of the water heater as a straw....if the straw has liquid in it and you put your finger on the top, the liquid doesn't come out. If you open up the relief valve, air will allow it to flow freely. The relief valve has a metal lever on it, usually on the top of the water heater (if electric).

SOURCE: I just installed a marathon

The top element should be heating if there is 240 volts across the element terminals. I take it that the top element is the booster element. The thermostat for the top element is normally a 2 pole thermostat which switches the neutral to the bottom thermostat once it reaches temperature. Once this occurs then the bottom element will start to heat. The top element will only come on when you use all the hot water. Is this supply on the off-peak rate? When testing always check the voltage across the element terminals.

Need a wiring diagram for rheem electric water 50 gallon 2007 model


1) Copy following links for standard wiring that applies to all brands electric water heater: wire colors vary, and do not matter.
You probably have ordinary residential non-simultaneous water heater.
http://waterheatertimer.org/How-to-wire-water-heater-thermostats.html
http://waterheatertimer.org/images/WH-w-combined2-1000.jpg

2) Look at tank label.
Typical label will show number of elements (upper and lower)
And give wattage for each element.
http://waterheatertimer.org/Figure-Volts-Amps-Watts-for-water-heater.html#label
http://waterheatertimer.org/images/Whirlpool-energy-smart-watt-rating-IMG_2600.jpg
Notice also total connected watts.
If total connected watts is same as individual upper or lower element watts, then you have ordinary residential non-simultaneous tank.

Can I install 4500 wt elements in a marathon MR50238? The tank specs are the same as MR 50245.


1) Product warranty will be voided if you install 4500 watt elements in year-2008 model MR50238 3800 watt marathon tank.
Older 3800 watt element models have been discontinued.

2) Copy following links for Marathon resources:
http://waterheatertimer.org/Review-Rheem-Marathon-water-heater.html
http://waterheatertimer.org/How-to-replace-water-heater-element.html

3) Product warranty is voided if element wattage exceeds label on side of unit.

4) Marathon has a problem with elements burning out frequently.
To solve this problem, they suggest installing element with lower wattage, such as the 3800 watt.
Upper 3800 SP610130
Lower 3800 SP210197

How to wire a rheem 40 gal electric hotwater heater with a yellow,blue, and Black wires


Jan 2013
1) Water heaters can be wired many different ways.
Copy following link For ordinary household 240Volt water heater, the heater is wired for non-simultaneous operation:
http://waterheatertimer.org/images/WH-w-combined2-1000.jpg
Copy following link For other wiring diagrams, including off-peak, simultaneous, redundant, etc
http://waterheatertimer.org/How-to-wire-water-heater-thermostats.html

2) Make sure water heater circuit breaker and wire size matches watt rating that shows on end of each element.
http://waterheatertimer.org/Color-codewire.html

3) Non simultaneous means only 1 element is ON at a time.
So either upper element is ON, or lower element is ON, or both elements are OFF.
Both elements are never ON at same time.
So non-simultaneous water heater with two 4500 watt elements has total connected watt rating of 4500 watts. Because only 1 element can be ON at a time.
Use 30 amp breaker and 10 gauge wire.

Need to increase the recovery rate of Rheem 82SV30-2 elect water heater. Has 4500w upper and 3380w lower elements. Was told by County Health Dept that it was possible to wire both elements together for...


Basic information: Typical electric water heater operates in non-simultaneous fashion where either the upper element is ON, or the lower element is ON, or both elements are OFF, but both elements are never ON at same time.

Easiest way to increase recovery. If you have 10 gauge wire and 30 amp breaker, then install two 5500 watt elements. This will not work if you have smaller 12 gauge wire and 20 amp breaker.
Watt rating appears on side of each element.
http://waterheatertimer.org/How-to-replace-water-heater-element.html

Change wiring.
If you run two separate 10 gauge wires to water heater, with each wire on a separate 30 amp breaker, then you can 'wire both elements together' to operate in simultaneous fashion. The elements are each wired independently of each other, but they can both turn ON at same time, and this action avoids heating lag if you also install larger 5500 watt elements.
Simultaneous water heaters can be ordered from manufacturer, and this is common with 80 gallon models where tank must keep up with larger demand.

How do I wire around upper heating element until I can get an other one to replace it?


Question posted under marathon electric water heater.
Marathon is 240Volt dual element non-simultaneous water heater.
Non-simultaneous means that upper part of tank has to reach temperature before power is sent to lower thermostat and element. So if upper element is bad, then water heater has no hot water.
http://waterheatertimer.org/Replace-anode-rod.html#audibleBW

1) You need to by-pass upper element without by-passing upper thermostat.
2) You should never by-pass upper thermostat because it has ECO-reset protection.
http://waterheatertimer.org/How-water-heater-thermostats-work.html

3) Open following link for image of wiring:
http://waterheatertimer.org/images/Marathon-wiring-700.jpg
4) Take photo of your wiring in case color code is different on your specific model

5) Look at upper thermostat.
Remove yellow wire from terminal 2 on upper thermostat, and cap off temporarily.
Remove red wire from terminal 4 on upper thermostat, and move it to terminal 2 on upper thermostat.
6) For more effective operation, look at lower thermostat.
Remove black wire from lower thermostat terminal 1 and move wire to terminal 2 on lower thermostat.

Brand new water heater is not heating up. checked the upper heat element and got 240 volts reading, the bottom one is not reading any voltage. Please help


1) If upper element is receiving 240V, then water heater should have some hot water.
If upper element is burned out, then tank will have no hot water, but element will still test for 240V
http://waterheatertimer.org/How-to-test-water-heater-element.html
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html

2) Keep in mind that upper element heats top part of tank first.
Only when top part of tank reaches thermostatic temperature will power be sent to lower thermostat and element. This is called non-simultaneous operation.
http://waterheatertimer.org/How-it-works.html

3) Non-simultaneous operation is necessary for most water heater installations because both elements are not ON at same time. Either upper element is ON or lower element is ON or both are off.
Each element is typically 4500 watts, which is 18.75 amps.
If both elements were ON at same time, it would consume 37.5 amps, so circuit breaker would have to be 40 or 50 amp with 8 or 6 gauge wire.

Whirlpool E1F50RD045V 50 gal elec. , top element is on bottom element is not getting 208 v, removed both legs from bottom stat has120v on each side not getting 208 from top , is their a relay not closing...


Sounds like you might have a thermostat problem, or burned out lower element
Lower thermostat and both elements will test for 120V at all times because upper thermostat only cuts off one leg of 240V circuit, and other leg is hot all the time.

http://waterheatertimer.org/How-to-wire-water-heater-thermostats.html
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html

Yes, the elements alternate being turned ON.
This is called non-simultaneous operation.
Look at label on side of tank: Each element has rating of 4500Watts, but tank rating is also 4500Watts > that shows that both elements are not ON at same time.
This is standard wiring for water heaters.
http://waterheatertimer.org/How-it-works.html

Water heaters can we wired differently, for example converted to simultaneous operation where upper thermostat and lower thermostat are no longer wired together, so upper and lower parts of tank are independent.
Lower thermostat is replaced with ECO protected thermostat identical to upper thermostat.
Another 240V circuit breaker is added to breaker panel, and that 240V line runs directly to lower thermostat. So upper and lower thermostats are each on separate 240V line.
The advantage of simultaneous is faster recovery of hot water, but downside is probably higher electric bill. Simultaneous wiring is usually reserved for larger tanks like 80 gallons, where elements can fall behind the amount of hot water needed.
Otherwise, ordinary non-simultaneous operation is proven to be satisfactory, if your home has not experienced shortages.

Rheem 40 gal. elct. have 220 at both elements all the time but only one drawing?


Your testing may be off here. Or you might have special order 'simultaneous' wired water heater.

Water heaters with two elements are 240V.
Elements test for 120V at all times, but with ordinary non-simultaneous water heater, only one element at a time has 240. This is called non-simultaneous operation.
Open links below for understanding of water heater operation.
http://waterheatertimer.org/How-it-works.html
http://waterheatertimer.org/How-water-heater-thermostats-work.html
http://waterheatertimer.org/B220C.html

If both elements were drawing 240 at one time, then upper thermostat is bad, or else your water heater is wired for simultaneous operation, and one of the elements is burned out.
http://waterheatertimer.org/How-to-test-water-heater-element.html
Your tank might be wired for simultaneous operation, if water heater was special order from Rheem, or if somebody changed wiring and set lower thermostat-and-element on a separate circuit breaker.

If you have simultaneous operation, then you would have 2 circuit breakers and 2 wires going to water heater or one 50 amp breaker with 8 gauge wire to heater. If this is the case, then both elements could test for 240V and one of the elements is bad, and thermostats are ok.

If you have ordinary Rheem water heater, then it is wired for non-simultaneous operation where only one element is ON at a time. This is called non-simultaneous operation and you can check because water heater has one circuit breaker rated for 20 or 30 amps.

Rheem elements are 4500Watts.
If both elements were ON at same time, that would be 9000Watts, which would trip typical water heater 20-30 amp circuit breaker.
9000Watts divided by 240 volts = 37.5 amps
So if upper thermostat is bad, and it is turning on both elements so they both test for 240, then thermostat is bad, but also one of the elements has to be bad.
Or test is inaccurate.
Interesting puzzle.

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.

My electric 58 gal whirlpool water heater runs out of water faster then normal. I took my amp probe and had current draw on lower element but not on upper then turned thermostat up heared relay click then...


http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html

You have a 240V electric water heater because you have an upper and lower element

The upper thermostat works in the manner you have discovered
.
In residential electric water heaters, the upper element is ON or the lower element is ON, or both elements are OFF.
This is called non-simultaneous operation.
Non-simultaneous operation means the elements are never turned ON at the same time.

Because water heater thermostats only turn off one leg of the 240V circuit, the upper and lower elements will always have power on the two screws, but not across the two screws.
This power is 120V and the circuit is not complete so the element will not heat.
So if you test any element, it will always show at least 120V
Only when the thermostat clicks ON is the 240V circuit completed, and the element turns ON.

Identify the problem:
1) The shortage of hot water is caused by a bad upper or lower thermostat or a bad lower element.
We know the upper element is working because you have some hot water. If the upper element was burned out, you would have no hot water because the upper thermostat would never click over and send power to lower part of water heater.

2) It sounds like your upper thermostat is clicking on and off, so I would test the lower element.
