What brand and model is your new water heater? Are you sure you don't have the water inlet and the water outlet reversed?

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.

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.

For residential water heater, 30 amp is best... but must have 10 gauge wire.

If you have 12 gauge wire, then use 20 amp breaker and install 3800 watt elements in place of 4500 watt elements

Can I install a junction box before my water heater junction box?


Junction box is fine.
Must be accessible and not hidden inside wall.
http://waterheatertimer.org/Color-codewire.html
http://waterheatertimer.org/How-to-select-right-wire-nut.html

43 feet is not over 100 feet, so wire size can stay same.
Recommend 30 amp breaker and 10 gauge wire for 4500 watt water heater.
If circuit has 20 amp breaker and 12 gauge wire, recommend 3800 watt elements.

We just installed a hot water heater that's


1) Test elements, and if elements are good, then replace both thermostats.
Takes about 20 minutes. Power is off.
http://waterheatertimer.org/How-to-test-water-heater-element.html
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html

2) Label on side of water heater shows volts and watts.
For 4500 watt elements, you need 30 amp breaker and 10 gauge wire.
Move water heater wires to different same-size breaker.
http://waterheatertimer.org/Color-codewire.html

3) Open the links and do the work, or call plumber to do work, or call manufacturer for warranty coverage.
If your wire and breaker are problematic, then service is not free.

I have a Rheem 82vs50-2. Can this heater's elements be wired continuous for 9.0kw and is there any mfr documention that allows continuous wiring of this heater


You have dual element 240Volt tank-type electric water heater.
You want to change wiring from non-simultaneous to simultaneous.
Copy following link for exact internal wiring diagram, and external wiring change: Remember the wire from breaker box will not support both elements without tripping breaker, so you will need additional 30 amp breaker and 10 gauge wire, or single 50 amp breaker and 6 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.

Copy following link for illustration showing how to rewire for simultaneous operation:

My reliance 501 is leaking at both entry hoses ports and also is very hot to the touch near the electrical connection port on the top of the water heater.


Emergency steps:
Turn electric power off.
Release tank pressure by opening bathtub faucet on hot side.
Turn off water supply to heater.
You can turn water heater ON for short periods (1/2 hour) to make some hot water until repairs are made.

It sounds like runaway heating caused by shorted element, possibly caused by leaking water. But I cannot tell for certain what the problem is. Read following links and/or call plumber.
http://waterheatertimer.org/Leaking-water-heater.html
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html

Over-amping:
Look at watt rating label on side of tank.
For example 4500 watt water heater requires 30 amp breaker and 10 gauge wire.
If you have 20 amp breaker and 12 gauge wire, then change elements to max 3800 watts. Tank will heat more slowly.

You have to fix leaks, and I cannot see that problem. Call plumber or repost question with clear description of leak.

Can i replace 4500watt elements with 5500watt on a 606 model


1) Manufacturer's warranty will be voided, and I've never seen recommendation that suggests better heating or saving money from replacing 4500W with different wattage element.

2) That being said, you have 240V water heater.
4500Watts divided by 240 = 18.75 amps
5500Watts divided by 240 = 23 amps

20 amp circuit breaker with 12 gauge wire is rated for 80% of load = 16amps
30 amp circuit breaker with 10 gauge wire is rated for 80% of load = 24amps.
http://waterheatertimer.org/Figure-Volts-Amps-Watts-for-water-heater.html

3) You can use 5500Watt element if you have 30 amp breaker and 10 gauge wire.

I have a Rheem Model # 82V52-2 and its being supplied by 25 amp breakers. They do not trip out but the 100 amp main gets real hot and trips out and I believe it happens when the water heater is in use- any...


The Rheem water heater uses 4500 Watt elements
Check label on side of any appliance to see electrical rating details
2 element tank with two 4500 watt elements is still a 4500 watt appliance since both elements are never ON at same time.

Volts x amps = watts
amps = watts divided by volts

amps = 4500 divided by 240Volts or 220Volts
amps = 18.75
Your water heater uses 18.75 amps to 20.45 amps

Your 25 amp breaker should only carry 80% of rated value
25 amps x 80% = 20 amps.

So your water heater breaker is correctly sized.
You should have a 10 gauge wire going to this water heater.
12 gauge wire is a bit undersized for 4500 Watt water heater
Feel the water heater wire to see if it is warm.

If the main breaker is getting hot when 20 additional amps are being used by the water heater.
1) The house is using more amps than your 100 amp main can carry
Using the formula, 100 amps x 80% = 80 amps for the main breaker
Add up your total amp draw.
For example if your 3500 watt oven is ON, it draws 16 amps.
If your 5000 Watt electric heater is on, it draws 23 amps.
Your 1500 Watt 120V microwave draws 12.5 amps.
Add these numbers up plus your water heater, and it comes to 71 amps.
71 amps is getting close to the max 80 amp, but it's not over.
Now if you have a pool pump and and hot tub and a table saw going, the main breaker could be overdrawn.

2) To solve the problem short-term, you can put a timer on the water heater and use it only when needed.
http://waterheatertimer.org/Compare-13-electric-water-heater-timers.html

3) The main breaker is bad and needs to be replaced.

Purchased "Reliance Lowboy electric water heater"


The water heater has two 4500 watt elements.
However both elements are not turned-ON at same time
So the water heater is 4500 Watts

Volts x Amps = watts
Amps =watts divided by volts
Amps = 4500 Watts divided by 240 Volts
Amps= 18.75

So that says a 20 amp breaker ... except for the 80% rule
80% rules says for safety, your Amp rating should be multiplied by 80%

20 amp breaker X 80% = 16 amps
20 amp breaker is actually safe for just 16 amps, and your water heater draws 18.75 amps.

The calculation shows you need a 30 Amp breaker.
30 Amp breaker requires 10 gauge wire.
