SOURCE: WATER IS NOT HOT

Check the thermastat, located in removable panel. warning dont set above 120- 130. If not the case it could be a bad heating coil. Easy to change in electric just googl a how to sitr. If your not Real Handy with Your Handa I would recomend calling a plumber to check heating element, Could be cheaper to replace

SOURCE: takes too long for hot water.

You need a recirculating line. You will have to hire a plumber to run a water line from the farthest fixture or to the fixture you are concerned about on the hot side and return it back to the water heater. this will cause hot water to constantly run throught the hot water line (via the recirculating line) and when you want to draw water from the fixture, you will already have hot water right at the line.
I know this works with standard tank water heaters, but it is a lil trickier with rinnai units(but very possible) if your plumber pleads the 5th and tries to sell you another unit call the Rinnai manufacturerand ask them how.

SOURCE: Our electric water heater doesn't work.

make sure it is wired correctly, check circuit breaker, check breaker built on to element. If all fails, and it is determined your not getting power to it, you may need a electrician. Be careful. good luck.

You have clog in the water line.
Since all hot water pipes are involved, clog is probably near water heater.

Buy pressure gauge at hardware store that threads onto hose connection.
Brady BTG 100 at Amazon
Picture of gauge

Check outdoor pressure for baseline pressure in your home.
Turn off electricity to hot water heater for an hour or two so there is not scalding water.
Open drain valve on water heater to see if water heater is clogged with sediment.
http://waterheatertimer.org/Water-heater-will-not-drain.html

Put pressure gauge on drain valve and compare with outside pressure.
Open hot water spigot on bathtub and see if tank pressure drops ... if tank pressure drops significantly with bathtub spigot on, then clog is on incoming cold water before tank, and could be on outgoing hot water pipes too.
If tank pressure stays about the same, then clog is on outgoing hot water pipes.

Clog can be sediment caught in cold water shut off valve located above tank. Open and close valve and test pressure again. Take apart incoming cold water pipes above tank and check for sediment. Replace valve. Look at condition of cold water nipple on top of tank.

Sediment caught at hot water elbow near tank.
Sediment can fill up old pipes. Take apart hot water pipes above water heater and see condition.
Look at condition of hot water nipple on top of tank.
You may have to take apart pipes up to first or second elbow.

Pipes can decay at joint where copper pipe connects to galvanized pipe. Check for copper to galvanized connections on cold or hot pipes and replace section of galvanized pipe. Copper pipe will probably be good, the galvanized pipe will deteriorate. Replace copper-to-galvanized joint with 3/4" non-conducting union from hardware store

Why does the water suddenly runs COLD after many minutes of running hot?


Unless you are using a tankless hot water heater, there is a limited amount of hot water available in the tank. Electric and gas water tanks need time to recover after use, and if you are using heavily, it can exhaust the available supply. That said, there are a couple reasons why you may have less hot water than seems normal. In both electric and gas water heaters, silt can form in the bottom of the tank. This will build up over time and displace water. It also reduces the heating efficiency of gas units. There is a drain valve on the bottom of water heater tanks to allow for purging of this silt periodically, but few ever do it. You could also have, in the case of an electric hot water heater, a bad element or thermostat. Most electric heaters have an upper and lower element and thermostat. If one fails the other will still work, but the water takes longer to get hot and will deplete faster.

I have water in the junction box on top of my hot water heater and into the electrical conduit leading to the hot water heater.


I do not see your earlier post with photo.

The problem could be the conduit.....
-disconnect the conduit and wires from water heater
-run wire into a junction box set lower than top of water heater... -then run another #10 wire from the junction box up to water heater...
-So if water is coming from conduit, it will accumulate into junction box and not in the water heater wiring cavity.

Next thing....
... a water softener can cause rusted tank.
-Softened water adversely affects anode rod...
-causing anode rod to deplete faster...
-once anode rod is gone, then tank begins to rust.
-Here are details for checking anode rod each 2-3 years:

Runs out of hot water fast


Test elements, and if elements are good, replace both thermostats.
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html

Rheem does not post service manuals.
If this is 3-phase balanced water heater, then information above is altered.
Otherwise parts are generic and testing steps are same

Can I run the hot water heater with a generator


Yes.
Ordinary electric water heater can run on any voltage from any direction (excluding volt/amp ratings below what can heat element coil).

Voltages include single-phase, split phase, and 3-phase residential/commercial voltages with either 50 or 60 Hz.
http://waterheatertimer.org/How-to-wire-water-heater-for-120-Volt.html
http://waterheatertimer.org/How-to-wire-water-heater-thermostats.html#3-phase

Install line fuse.
30 amp fuse would be required to prevent wires from overheating, and eliminate fire hazard.

This information does NOT apply to energy-smart electric water heater with box on top of heater, or newer energy smart with electronics, or to hybrid water heaters, or heat pump water heaters with delicate electronic circuitry.

Why it works like this:
Ordinary electric water heater thermostats are mechanical bi-metal switches and respond to tank temperature, and are not operated by electricity.
Ordinary generic elecrtic water heater thermostats switch electricity on-off using mechanical bi-metal switch.
Heat elements are simple coil of thermal wire that gets hot when voltage is applied.
The element will get hot when power is applied.

No heat the water.


Suddenly no hot water: Red reset button tripped, circuit breaker tripped, bad upper element, bad thermostat, loose wire, TP valve is running hot water out of tank, leaking faucet is running hot water out of tank.

1) Check for leaks.
2) Check circuit breaker.
3) Open top cover on water heater and push in red reset button.
If reset is popped out and will not reset, replace thermostat:
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html
4) Test upper element:
http://waterheatertimer.org/How-to-test-water-heater-element.html
5) Loose wire

The hot water is no longer very hot, just nice and warm. What caused this? I have an electric water heater.


Listed below are suspects in order of ease.

1) Check that hot water is not running out of TP valve and down into a drain.
This will cause water heater to run all the time but not be able to keep up.

2) Test elements before replacing anything:
http://waterheatertimer.org/How-to-test-water-heater-element.html
http://waterheatertimer.org/How-to-replace-element.html

3) Test electricity to water heater:
http://waterheatertimer.org/Test-electricity-to-water-heater.html

4) Replace both thermostats.
