water leak: turn off all taps and put ear against pipe and listen for water leak... check if water meter advances when all water taps are off.

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.
http://waterheatertimer.org/How-to-replace-water-heater-element.html
http://waterheatertimer.org/Increase-amount-of-hot-water.html
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.

How long will it take Rheem solar hot water to heat up


read manual:
http://www.rheem.com.au/Assets/1294/1/Rheemsolarlolineelectric511series.pdf
Usually electric element heats about 20 gallons per hour.
It appears the element is controlled by thermostat and automatically kicks ON when tank falls below thermostat set point..
This will be handy since element will continually heat the circulating water when outside temperatures turn cool... of course it will also be wasteful if thermostat is set high.

I HAVE A 30 GALLON DUAL ELEMENT WATER HEATER I HAVE 120 VOLTS COMING IN BUT AM ONLY GETTING 60 VOLTS TO BOTTOM THERMOSTAT


jan 2013
Reset circuit breaker.

1) Dual element tanks are 240Volts.
Copy following link for troubleshoot walk-thru
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html#electricity
http://waterheatertimer.org/How-it-works.html

2) Buy cheap multi-meter at hardware, and test for 240Volt across top two screws on upper thermostat.

3) Add a comment for more assistance

Hello - I have a 6-7 yr old Whirlpool EnergySmart 50 gallon 5500 watt water heater. (Two control boards fried and were replaced free). Symptom now is not enough hot water. No 'error codes' are blinking...


1) Residential water heaters are non-simultaneous. Only one element works at a time.
Upper element comes on until top of tank is heated, and then lower element is switched on until lower part of tank is heated. Lower element keeps tank hot during standby hours
http://waterheatertimer.org/How-it-works.html

2) Typical Whirlpool energy smart has 4500Watt elements. Look at label on side of tank
If both elements were ON, that would draw 9000Watts or 37.5 amps, requiring 50 amp breaker and 8 gauge wire. V x A = Watts.
All dual-element tanks are 240V.
Whirlpool energy smart requires 10 gauge wire and 30 amp breaker so electronics are not starved during operation. If your wire or breaker are undersized, that is suspect for repeated failure.
http://waterheatertimer.org/Whirlpool-Energy-Smart-electric.html

3) Typical electric water heater heats 21 gallons per hour. First hour delivery is higher since elements heat water as you use it. Overall however, electric water heater cannot re-heat as fast as gas because gas water heater burner carries more BTU punch per minute than electric element. Gas heats about 41 gallons per minute, with higher first hour delivery.

4) IF YOU HAVE OLDER energy smart and installed newer board, then you could have non-simultaneous operation is reversed so that lower element comes on first.

Contact Whirlpool 1-877-817-6750

5) Another potential problem is that you have sediment inside tank and that is reducing efficiency of lower element.

How do you set tempature to make the water stay hotter longer? I have a Rheem 82v66 2 (65 gal) and cant fill my bath tub with out running out of hot water.


65 gallon water heater should fill more than 1 bathtub since typical bath only uses 12-14 gallons hot water. First hour delivery on your tank should be greater than 60 gallons.
http://waterheatertimer.org/Hot-water-use-chart.html

Since you have such a small amount of hot water, it sounds like bottom element is burned out, or one of the thermostats is bad. There are two thermostats, and two 4500 Watt elements on 65 gallon tank.
If upper element was burned out, or water heater was not getting 240V electricity, then you would have NO hot water. So we know upper element is good and circuit is good.

Ordinary tank-type electric water heater is fully repairable by homeowner and parts are available at hardware or home center.
I suggest taking 30 minutes and doing troubleshoot before replacing any parts.
Buy cheap multimeter from home center.
When testing voltage, rotate multimeter dial to 240-250-277 VAC
When testing elements or continuity, rotate dial to Ohms.

I have a GSW Series 5 water heater (electric). I think the heating elements are bad or going bad. The heater is about 12 years old. Its a 40 gallon heater, and I've noticed the amount of hot water is less...


It may be one of 2 elements not working, a thermostat problem, scale build up in tank, to name a few possibilities. You'll need to shut off power to water heater before doing anything to it, and perform a few tests, and check a few things to determine which one is the cause. After power is off, you remove cover(s) on side of tank and peel back the insulation to get access to element(s). Keep in mind that should you need to change one of the elements, or both (assuming it has 2 otherwise you wouldn't have any hot water at all if only 1 element and not working.) This is where it would be good to have a voltage meter ( or multimeter ) and know how to use it. Is that possible? Before you reply, please shut off power and remove cover(s) to be sure whether single or dual element. If it's single, it may just be thermostat adjustment, or faulty, or scale build up around element. Keep in mind that water to tank will need to be shut off and tank drained down below element before removing/replacing. Get back to me with info on single or dual element. Thanks

Energy smart hot water heater not giving ample amount of hot water both elements ohm at 12.5


element-connection-450.jpg
For images and product information
For manual


You checked ohms, did you check for 240V across lower element when lower element is turned on?

Energy smart electric water heater
has a control box on top of unit. Water heater does not have typical thermostats that can be tested and replaced. Temperature sensors located above each element send information to control box through small black and red wires. Temperature sensor sells for about $40, but there is no test listed that shows how to determine when sensors fail.

Potential problems:
-Temperature sensor is not reading correct temp
-Control box not processing correct temperature information
-Selector on control box set to 2, 3 or 4
-Thermostat temp on control box set lower than 120 degrees F
-Sediment build-up starting to surround lower element so water doesn't circulate (see if drain valve runs full-open

We have a new Rheem 30 gal short water heater. It only seems to put out about 10 gallons of hot water before it starts going cold,any suggestions......


I am assuming that everything was fine and then all of the sudden available hot water usage time dropped.

On a dual heating element hot water heater it can be

1. Internal tank loaded with sediment (drain and purge from lower garden hose fitting)

2. Thermostat or element problem with ONE of the 2 heaters. (Trouble shoot element thermostat)

3. Check Circuit breaker for partial trip of the breaker.
