Check what the "AMPERAGE" (Amps) is stamped on the info tag on your present heater --- If the number is the same or lower you shold be able to use the same wiring -- If the amperage is lower all you'll to do is lower the amp size of the fuse / braker

Reliant 40 gallon tall electric water heater replaced both thermostats upper and lower elements flushed tank hot water very hot temp turned down lowest possible keeps tripping reset button what else could...


Problem has to be bad element or bad thermostat.

Test elements for short to ground through metal tank wall:

Make sure factory-installed insulation and cover are re-installed over new thermostats so they do not misread tank temperature.
If problem does not show with elements, then replace thermostats again.

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.

Not enough hot water,running out before I'm finished showering.


Hello,

Hot water heaters are a touchy thing. There performance depends on your demand. If you are using an energy saving shower head I would expect you to have enough hot water for easily a couple of showers. But, if your using the "power flush" type shower heads that use 3.5 gpm or more, the 40 gallon heater is not enough. Also, consider type of water your heating. Is it well water or municipal. Unsoftened well (this includes some municipal well supplies too) water causes hardness ions to cake the heater element making them less efficient. If you have the low flow shower, it is likely you have an element burt out. They can simply be replaced and picked up at any big box store for less than $20 dollars. Each element can be tested in place with a continuity tester. If your not sure how to test, but would be willing to replace the elements - replace both of them. You will have to shut off power to heater and drain tank completely before removing elements. Replace elements with same wattage or higher. Most have two 2250 watt elements for a total of 4500 watts. you can easily install two 3000 watt elements and have a quicker recovery rate and more hot water than ever. Good luck.

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

Can i use the timer for a water headter to trun on and off


Paragon 8145-20 is a 240V defrost timer
It is probably not best choice for water heater timer
Timer initiates defrost cycles each 4 hours.

A water heater timer should have more scheduling options.
-For example estimates show average run-time for water heater is 3 hours per day, depending on incoming water temperature, thermostat setting, and number of gallons used.
-To save money using water heater timer, you have to schedule times carefully so water heater runs less than 3 hours per day.
-Now your average electric water heater heats about 20 gallons per hour.
-Average shower uses 4-9 gallons hot water, so water heater needs to run 15-30 minutes (15 summer, 30 winter)
-Average bath uses 12-15 gallons hot water so water heater runs 45-60 minutes
-But lets say you run water heater for 1 hour and make 20 gallons of hot water. Then you take a shower, expecting hot water to remain in tank.
-Here's the problem ... cold water entered the tank to replace the shower water ... and the new cold water is cooling the rest of the tank.
-So a timer means scheduling hot water to match shower and bath events. For example taking shower and bath in immediate succession.
-Or set the timer for each individual hot water event ... for example set timer for 1/2 hour for shower, and later timer turns on 1 hour for bath, or 1-1/2 hr for 2 baths, etc
-> The flexible programming described above is not a characteristic of defrost timers.
I suggest Intermatic WH-31 240V or Intermatic T-104 240V or GE 15207. These are mechanical repeat-24 hour timers with manual override where each day has same schedule.
Digital programmable timers like Intermatic EH40 offer 7-day, 40 event programming. Weekends and weekdays can be different.
To see several box-type timers:

My Reliance 606 40 gallon water heater only heats up enough hot water to fill a bathtub. We've drained it, the pilot light is fine, it heats up the water really hot, but it just doesn't seem to be able to...


How big is your bathtub? Is your water heater set on the hottest setting? What is the temperature of the hot water at the tap?

Keep in mind that hot water can cause severe burns. Children and those with diminished mental capacity can be seriously harmed by hot water.

The "40 Gallon" rating on the water heater is usually the amount of hot water the unit can produce in one hour. So the tank, and the amount of immediately available hot water, might be smaller than 40 gallons.

My bathtub is 2 feet wide by 1 foot deep and 4 feet long. This is 8 cubic feet or almost 60 gallons. So a 40 gallons of water at 120 degrees, mixed with 20 gallons of cold water (60 degrees), fills the tub with 100 degree water. My January cold water is 42 degrees, so it will take 40 gallons at 129 degrees to fill the tub. If the tub is cold to start it will take even hotter water.

So the water heater might be just fine.

Possible solutions:
1. turn the temperature up on your water heater- or the temperature control could be malfunctioning and not getting the water hot enough.
2. insulate your hot water pipes so that the water loses less heat on the way to the tub.
3. bigger water heater.
4. smaller bathtub, or less full bathtub.
