Question about Rheem 40 GAL ELEC TALL Water Heater 6YR SC 82VH402

Water heater does not produce as much hot water as it use to. Could it be, that one of the heating coils is out. If so is ther a reset switch? Before I have someone check the coils.

Ordinary tank-type electric water heaters are fully repairable by homeowner.

A) Rheem electric water heater website:
http://www.rheem.com/products/tank_water_heaters/electric_water_heaters/
Find age of Rheem: look 3rd and 4th digit of serial number, for example 06 is 2006

B) Water heater has some hot water.
That says certain things: upper element is working, water heater electricity is working, reset button is not tripped, and heater is not experiencing run-away overheating event.
http://waterheatertimer.org/How-it-works.html

C) That leaves 4 suspects.

1) TP valve is running hot water out of tank, or leaking faucet is running hot water out of tank.
Check for leaks

2) Lower element is burned out.
Test lower element using inexpensive multi-meter from Home Depot.
http://waterheatertimer.org/How-to-test-water-heater-element.html
Replace element with same wattage shown on label, and clean out sediment:

2) Upper or lower thermostat is bad.
Replace both thermostats for about $25.

3) Burned or shorted wire located between upper and lower sections of tank.
Turn off power. Open covers on side of tank. Remove insulation. Inspect parts for signs of high heat and burning. Especially check lower element. Tighten any loose wires. Replace part that shows signs of burning.
Put insulation and cover back over thermostats so cooler outside temperature doesn't cause thermostat to misread tank temperature.

You water heater most likely has a shorted heating coil, don't run it like this, call a service technician.

I have a power star ae115 electric tankless water heater. It has performed flawlessly for approximately 5 years. A couple weeks ago it stopped producing HOT water but is still heating to Luke warm. The "...


5 years is about the lifespan for tankless.
You might have shorted element. That would explain cooler water and tripping reset.
Test element: power is off, disconnect wires from element; ohms = voltage squared divided by watt rating of element

Very minimal hot water being produced from my water heater


1) Clean air intake, and do required yearly maintenance.

2) Gas control valve thermostat could be going bad, causing disruption of gas to pilot, and uneven heating of water.

3) Without knowing brand and model number that shows on label on side of tank, it is difficult to add specifics.

My Rheemglass Fury is not putting out much hot water


I believe that there are 2 separate electric heating coils in this unit (unless you are talking about the GAS unit). One of the coils either has a wire broken or the element needs to be replaced!

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.

Recently purchassed system from you plumber installed it and we asked specifically not to set it on child settings.....we have not had one HOT shower since. how do we go about resetting the hot water...


These Tankless water heaters attempt to heat water as it quickly travels through a short series of heated copper pipes. A high volume of water at an accelerated speed has little time to heat up as it passes through its heating source. You can turn up the temperature (which you undoubtably tried) and turn the water volume all the way down. These settings will produce the hottest temperature capable of the unit - given the entry temperature of your water source.
Most underground water enters at app 52 degrees - and becomes even colder due to ambient temperatures. Difficult to raise this temperature 60-70 degrees in a few seconds of heating.
I've routed a series of copper pipes adjesent to the home heating system in an attempt to pre-heat incomming water. It's only a few degrees warmer, but results a 20- 30 degree hotter delivery.
I have installed some top end units that simply delivers Hot water without compermise.
