Water heater not making hot water


1) Electric water heater can be repaired, no need for new one.
Copy following links:
http://waterheatertimer.org/images/Water-heater-ther-ele-600.jpg
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html#veryhot

2) Ordinary homeowner can turn 6-year electric tank into a lifetime tank.
http://waterheatertimer.org/How-to-maintain-water-heater.html

3) If you replace heater, then buy inexpensive tank-type from local box store, and use coupon or offer 10% off. Read the product manual.
Avoid tankless at all costs unless you are rich.
No need to buy expensive water heater on the promise of thicker insulation or higher energy factor, or 'lifetime elements' or 'advanced technology', any other slicker promotion aimed at folks with the promise of a golden rainbow of money-saving-bliss if only you would spend more money. All costs are energy. Expensive water heaters do not pay back, and 1 repair will dissolve all anticipated savings. And expensive heaters can never be maintained to last as long as ordinary tank-type electric.

Is the Whirlpool Electric Water Heater Model # EE3J50RD045V energy star rated


You want to know if this heater has Energy Star label.
I don't know.
Call Whirlpool 1-877-817-6750

Energy Star is a label that means nothing to you.
Manufacturers use energy-star label to promote a product as a money-saver.
They can put an Energy Star label on a giant 10,000 square foot house, and you know that cannot be the truth that a large house saves energy vrs a smaller house.

Energy factor, (energy factor/ not energy star) on the other hand, is a comparison measure how efficient the water heater uses energy to heat a gallon of water, when water heater is absolutely new.
EE3J50RD045V has energy factor of .59, which is completely typical and ordinary for electric water heaters.

The EE3j 50 gallon is an ordinary electric water heater, with ordinary average .59 energy factor rating, so electricity to operate this water heater is same as any other typical 50 gallon electric water heater: it will cost $35-45 a month depending on incoming water temperature, hot water use, thermostatic setting, electricity pricing, and whether you operate heater at peak pricing, etc.
http://waterheatertimer.org/9-ways-to-save-with-water-heater.html
http://waterheatertimer.org/How-much-does-it-cost-to-run-water-heater.html

The most important measure of water heater cost does not have anything to do with Energy-star or energy-factor.
The most important measure is total cost of owning and operating the water heater.
So if you spend $100 more to purchase electric water heater with slightly higher energy factor, then it will not pay you back. The difference will be $2 to $4 per year.
All costs are energy.
The total cost of operating water heater includes purchase price, installation cost, cost of repairs, cost of parts, whether you can fix it yourself, expected life of water heater, and replacement cost.
Every water heater has expected lifespan, and will not have resale value except current price of scrap.

Electric water heaters cost more to operate per month than same-size gas water heater.
Gas water heater might cost less over the life of water heater, but gas water heaters are increasingly expensive to repair, and increasingly more complicated, and cost more up-front to buy.

Electric water heaters cost less to buy, are easy to install yourself, are fully repairable by homeowner using generic off-the-shelf parts, and can be made to last many years by keeping tank clean and replacing anode rod every 2 years.
You can make ordinary 6-year electric water heater from box store last almost indefinitely.
Avoid electric water water heater that has electronic controls.

How can I find out what the Energy Rating is on my Reliance 501 w/h?


Reliance is AO Smith company.
http://www.reliancewaterheaters.com/prod/gas.html
http://waterheatertimer.org/Water-heater-manufacturers.html

1) Reliance does not post the 501 manual any more and I've written and asked for that manual, and they sent generic manual. Model 501 is both gas and electric.

2) That tells me the old energy factor is probably lower than .54 approximately, but it will be even less because energy factors are for new water heaters in perfect operating order under ideal conditions.

3) Energy factor is a measure of how efficiently the water heater turns energy BTUs into hot water.
Gas water heaters have higher energy factor because gas burner has more BTU punch than electric element, and can heat water faster.

4) However, energy factor is not measure of actual cost. It is merely a way to compare giant water heaters with smaller heaters, and gas with electric, without considering cost of heater, installation cost, repair costs, parts costs, life expectation of unit, disposal/recycling cost, or replacement cost.

5) You can improve your true energy factor by buying small cheap heater and maintaining it yourself so it lasts many years beyond manufacturer's warranty.
http://waterheatertimer.org/Replace-anode-rod.html

6) If someone buys a bigger water heater because it has better energy factor, it will not pay back the higher purchase cost. Same size to same size, the difference with higher energy factor is a few dollars per year.
http://waterheatertimer.org/How-to-install-gas-water-heater.html

7) If you have sediment inside of tank, the energy factor is out the window.

Read about energy factor:
http://www.energysavers.gov/your_home/water_heating/index.cfm/mytopic=13000
"...energy efficiency based on the amount of hot water produced per unit of fuel consumed over a typical day. This includes the following:
  • Recovery efficiency - how efficiently the heat from the energy source is transferred to the water
  • Standby losses - the percentage of heat loss per hour from the stored water compared to the heat content of the water (water heaters with storage tanks)
  • Cycling losses - the loss of heat as the water circulates through a water heater tank, and/or inlet and outlet pipes." end quote
Energy factors exist so large appliances can be compared to small appliances.
-This is like comparing aircraft-carriers to small ships.
-The purpose is so large gigantic appliances look like reasonable energy alternatives, when that is not actually true.
-The aircraft carrier could have better efficiency number than smaller ship, and it gives misleading appearance that aircraft-carrier will save the consumer money. Many of the super high-consumption 80 gallon water heaters have higher energy factor, but they consume huge amounts of energy each time operated. Simple Dort series is a better value even with lower efficiency number.
-The efficiency number is only for a new product. There is no measure showing how long that product will maintain the efficiency rating.
-And lastly, the manufacturer is putting energy factor on the product, like writing your own performance review, so who can possibly double-check the energy factor.

What is the energy factor for the mod.82V80-2? I have two seperate 30amp circuits, one for the top element and one for the bottom element, if that changes anything.


http://www.rheem.com/product.aspx?id=09DF2BDD-5E11-4D32-B574-84ACFB8A4619
http://globalimageserver.com/fetchDocument.aspx?id=052c9e32-ce37-48d7-8990-9e430f23fef3

82V80-2 Energy factor is .86 according to water heater industry self-regulated standards.

Rheem pdf says these water heaters are wired for non-simultaneous operation.
Except special order water heaters.
Non-simultaneous operation uses single 240V circuit as described below.
If your water heater is wired for simultaneous operation, and each element is on a separate circuit, that makes your water heater special order. I would guess the reason is for higher first-hour delivery, which implies rapid heating and would likely affect energy factor.
You might want to get serial number off model and call Rheem for specs on that special order.

Your water heater energy factor may be the same because 'energy efficiency is based on the amount of hot water produced per unit of fuel consumed over a typical day.' This means an aircraft carrier can be considered highly efficient despite overall cost. And naturally the guys making the aircraft carrier are also doing the rating.
http://www.energysavers.gov/your_home/water_heating/index.cfm/mytopic=13000

Non simultaneous operation means the upper thermostat controls heating functions.
240V goes to upper thermostat first.
When water inside tank is cold, thermostat reads temperature through tank wall.
Upper thermostat turns on upper element until top 2/3 of tank reaches thermostat set point.
Once set point is reached, upper thermostat turns off upper element and sends power to lower thermostat and lower element.
Lower thermostat reads temperature through tank wall, and turns on lower element until bottom 1/3 of tank reaches thermostat set point.
As water cools inside tank, lower thermostat is first to respond since hot water rises.
Lower thermostat turns on lower element until tank again reaches set point.
When hot water faucet is turned on, hot water exits top of tank.
At same time, cold water enters bottom of tank through the dip tube.
The heating cycle repeats.
At all times, the electricity flows through upper thermostat. And upper thermostat is powered by one 240V circuit.

With simultaneous operation, the upper and lower thermostats work in same manner.
Except thermostats are wired separately.
Lower thermostat does not wait for upper part of tank to be heated first.
Lower thermostat turns on whenever lower part of tank cools.
The advantage is more hot water available rapidly when demand is high. This is called first hour recovery.

One method for reducing electric consumption is to set lower thermostat so it only turns on during certain times of day. For example Whirlpool Energy Smart operates in this manner and shaves a few bucks off the bill each month. This says that simultaneous operation is not an energy saver, unless that circuit controlling lower thermostat is set on a timer.

Caluclation


This requires a little math....

BTU - amount of heat it takes to raise one pound of water 1 degree F.

I gallon of water = about 8.54 pounds

91 gallons of water = about 777 pounds = 777 pounds x 70 degree rise = 54,390 BTU.

1 Therm (what the gas company measuers in) is 100,000 btus

1 therm costs about $.45 (45 cents) depending on where you are

54,390/100,000 x $.45 = about $.25 per hour

This cost can vary somewhat depending on the inlet water temperature, gas cost, and the efficiency of the hot water heater

On-Demand Water Heater


An on-demand, or tankless, water heater is a system for heating water as it passes through the pipes, usually very near the point of use. Traditional tank water heaters bring the water to approximately 140 degrees Fahrenheit (60 C), in order to ensure the water supply lasts long after the heater turns off. Since this is obviously far too hot to be pumped out of a shower of faucet, cold water is added to the mix in the pipes. Coupled with the loss of thermal energy over time, the average tank heater has an efficiency of approximately 80%. On-demand water heaters have a number of advantages over their tank-using counterparts. While tanks often degrade over time and begin leaking, the apparatus used in an on-demand water heater is much less susceptible to the burdens of age, and will often outlive the house they're installed in. The amount of energy used is a fraction of that used in a tank water heater, due to increased efficiency and a much smaller window during which a heating source is in use. While tank hot water heaters can, and often do, run out of hot water after a number of showers, on-demand heaters provide a never-ending supply of hot water, ensuring that warm water is always available when needed. A tankless water heater can cost between $500 and $1500, and they most commonly use either electric or natural gas energy to heat the water. Most mid-sized households report an energy savings of approximately 25-45% for a gas or propane heater, and up to 50% with an electric heater, over using traditional tank heaters. Water is usually set to a maximum temperature of 120 degrees Fahrenheit (49 C), though many heaters allow for custom setting of the maximum temperature via remote control. Outflow rates range from 8-14 gallons (30-53 litres) per minute. Installation for most tankless water heaters is incredibly easy, involving simple plumbing. In the case of electric heaters, all that is required for a fuel source is to plug the heater into an outlet and begin heating your water. Some modern on-demand water heaters can incorporate a solar preheating system. This system uses a traditional solar heating system and tank to bring the water nearer to the desired temperature, saving substantial energy use in the final on-demand heating. A solar preheating system costs between $500 and $800.

How to Replace Water Heater


Before you rush out to buy a new one, you'll want to find out which type of water heater is most efficient. Your decision will be heavily predicated upon whether your home is set up to run an electric or a gas water heater. One general piece of advice is valid regardless: Don't assume you need to buy the same size water heater as you currently own. It is possible that you can install a smaller water heater if, in recent years, you have replaced other household appliances, such as dishwashers and washing machines. Newer products often include power and water saving features, and thus, you might be able to buy a smaller water heater that will cost less money and use less energy. Whether your requirements dictate gas or electric, learning which models are most economical is fairly straightforward. Federal regulations require that water heaters display Energy Guide labels. These labels include the Energy Factor (EF) that measures the overall efficiency of a model; the higher the number, the more efficient it is. The labels also will have a First Hour Rating (FHR) that indicates how many gallons of water that model will produce during a peak usage hour. Additionally, you can get energy savings information and rankings on some of the most popular brands of water heaters through consumer organizations and reports. A word about on-demand water heaters: On-demand water heaters, also called tankless water heaters, or spontaneous water heaters, can be fueled by either gas or electricity. This design is much more efficient than standard models. An on-demand water heater is smaller and does not keep a reservoir of heated water on hand for anticipated use. Instead, as soon as you turn on the faucet, the fuel source fires up and the hot water is delivered. This type of water heater requires some refitting during installation in order to provide powered venting and possibly a larger gas line, so it is best to hire a professional to do the job. On-demand water heaters are especially practical for small apartments or single-person households. Larger households will require multiple units. Once you have installed your new, energy efficient water heater there are even more ways to increase its efficiency. Remember to purchase insulation blankets, lower your thermostat, add an overnight shutoff timer, install heat traps, insulate your pipes, and be diligent about regular maintenance. If you take these steps, you can rest assured that you will have the most efficient type of water heater available.
