1 Answer

My electric bill is high $240 plus per month I have a gas stove, gas dryer,gas hot water heater and energy saver florescent bulbs throughout. Only two of us home. My A/C is set at 78 degrees. Could my A/C and heat strip possibly be running at the same time and if so how can I tell.The central A/C-heat is the only appliance we have on 240 volt. Is there a way to disconnect the heat strip for the summer?

Yes the heat could be running at the same time the cooling is on.
Take a Amp meter and read your amp draw on the air handler wiring while running.Any reading above 2.5 amps should be checked out.that is 2 point 5.

Why is my hot water heater is using too much power?


It almost sounds as if someone is hooked into your electrical system check for outside cables or extensions cords going into a window or even at the fuse box

Water Heaters go Tankless


You may or may not have heard about these cool little devices by now, but if not, here is the low down.

Tankless water heaters are used all across Europe and come in several varieties.

1. Natural gas fired on demand Tankless
2. Oil Fired Tankless
3. Electrical Tankless

The most prevalent among these is the gas fired version.

In America, these energy savers are just starting to gain a foothold.
Leaders in the field are Titan, Bosch, Rinnai, and Noritz to name a few.

The real benefit to Tankless over Standard water heaters is that you never waste energy heating water that sits in a tank cooling until you use it.
If you have a 20 to 80 gallon water in your home, it will run night and day at odd internals maintaining it's own heat.

What this means to you is that in a typical day, whether you use hot water that day or not, is that your water heater will cycle many times to maintain it's heat whether the hot water is used or not.

Some people try to drive this wasted energy use down by wrapping their water heater with thermal blankets, or by insulating the water heater closet itself, which has only proven to be partially effective.

Also bear in mind that these Tankless water heaters are quite small compared to the Tank version, some are as small as 18 by 12 inches.
This means that your old water heater closet can now be used to store your valuables without fear of starting a fire.

A further waste of energy occurs when the exhaust heat is funneled to the outside when it could have been diverted to a heat exchanger or other energy conservation device.

Tankless water heaters perform far better in energy use than the old school, Tank type water heater by simply heating water exactly when it is needed, then shutting down when the hot water tap is turned off.
What this means for you, the consumer is that you will have hot water any time you need it, and the water will remain hot as long as the hot water tap is opened.

There are virtually no cold water periods for a tankless water heater.
You have an endless stream of hot water, without wasting a single BTU of heat, kilowatt of electricity, or ounce of natural gas.

The real surprise here is that nobody really knows just how much their utility bill is being affected by that Tank style water heater until the first utility bill arrives. The savings are immediate and significant, both in terms of less energy consumption and Dollars saved.

Let me drive that point home in real life terms.
You definitely will NOT use MORE energy after your install.
You will most Certainly use less!

There are several typical applications for Tankless systems in any common home.

1. Low Volume On Demand heaters can be installed under the sink.
2. High Volume Tankless Whole House heaters supply the entire home.
3. On demand Budget Tankless heaters can be located at the sink coupled with whole house heaters for faster hot water delivery to eliminate cold spots. These are the most popular for the beginner Tankless solutions.
Your cold water pipe is split from the cold water valve itself to the Tankless heater under the sink as well as the cold water tap. The hot water outlet is then connected to the Tankless water heater under the sink to provide instant hot water, eliminating the need for a hot water tap from the main hot water supply. This results in even less energy waste since the smaller Tankless heater uses less energy than a whole house Tankless unit.
4. On demand Tankless heaters use virtually no energy to heat unused water. When the hot water tap is off, the Tankless unit is off.

The price point for these Tankless models is fairly competitive against a standard water heater, but can sometimes be more expensive depending on the model and water volume you require. What matters most though is that these Tankless versions begin paying for themselves the day they are installed.

My final word on this is simple.
Most other countries in the world have been using tankless water heaters for a very long time due to natural gas and oil prices. Their adoption of these devices is a necessity rather than a purchase of convenience.
In terms of technology, America falls close to last place in this field, as well as many other areas where energy consumption is a factor.

When you purchase a Tankless water heater, you not only save money, but you also help the environment by wasting less energy to heat the same amount of water you consume on a per use basis. You will also use somewhat less water since you no longer have to wait for that cold water to leave the tap so the hot water will finally flow.

The choice is yours.
Choose wisely!

Bosch 125fx heater barely heats water


1) Recommend replacing tankless with ordinary tank-type gas water heater.
http://waterheatertimer.org/How-to-install-gas-water-heater.html
http://hometips.me/Mar/Which-is-best-gas-water-heater.pdf

2) Tankless cannot be exposed to more than 11 grains hardness in water or unit will fail within 2-5 years. Water softener is required.
http://hometips.me/Tls/Battelle_Water-softening-research.pdf

3) Descaling tankless water heater each year will not restore functionality, or restore efficiency of tankless, nor restore full efficiency to tank-type gas water heater.

4) Bradford White side-by-side testing research comparing their tankless with their tank-type shows that tankless will save $1-8 per month on energy bill vrs ordianry tank-type ....but conclude that tankless 'fall far short of payback' due to maintenance, repair, installation and replacement costs.
Study compared full cost, and not just monthly energy bill, since All costs are energy.

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.

I want to reduce my bail of electric every month


To reduce your electricity bill please do the following:
1. Make sure that you use only and only those lights you want at a time.
2. Use low rating electrical gadgets like bulbs - 18 to 20 watts(energy savers), kettle/cookers/hot plates - 500 to 1500watts, flat irons - 800 to 1000watts, etc
3.When you are boiling on a cooker, when some food boils - you can turn the rating lower using the knob. Don't keep the knob high all through boiling.

If this solution is helpful, please rate me accordingly. thanks

I have this timer hooked up onto my water heater in the garage . I have instant hot water at all times . My gas bill is 5 times higher than my neighbors . Is this what is causing it ? If I unplug it where...


I think you have a grundfos recirculation pump.
This is not a water heater timer.
For illustration of grundfos system, open link below.
http://waterheatertimer.org/Water-heater-recirculation-system.html
Recirculation system is electric, but it also causes gas water heater to run more.
Unplug grundfos for a couple months to see if gas bill goes down. Your system will revert to regular water heater.

Many things can cause high gas bill. Make inventory of gas-consuming appliances: dryer, oven, stove, heater, water heater. Then inventory how often these appliances are used. Each appliance has a label with BTU listed. Add up BTUs of all appliances and compare with BTUs shown on gas bill. Call gas company about how to cut back.
Gas water heaters can become inefficient. So can any gas appliance. Look at flame inside water heater when it turns on. If flame is yellow instead of clear blue, that indicates the water heater is inefficient, and burner needs to be cleaned, or heater needs replacement or maintenance.
Call plumber for assessment and then post a question on the Tank to double check anything plumber says:
http://www.thetankatwaterheaterrescue.com/forums/forum3/

More information about circulation system:
Notice that illustrations show a pump located under the sink.
It sounds like you have same pump located at water heater.
Both types are same thing.
The purpose is to circulate hot water to your faucet so you don't have to wait for hot water when turning faucet ON. Instead, you have to wait for cold water.

The timer located on grundfos dial determines when pump turns ON.
Link above has illustration showing how to set timer pins using your thumb or ink pin or nail file (women know nail files, so I'm relating here).
To set timer, rotate dial until current time lines up with mark. The dial rotates as time passes and has to be reset after power outage.
If dial does not rotate, then timer is broken, but it sounds like pump is still working, and running full time which is wasteful.
Next, move the pins to set on-off times. Move pins inward, the pump is ON. Pins outward, pump is off.

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.

How do you reduce an electric bill in a all electric house?


The biggest wasters of electrical energy are Heat and A/c, water heaters,dryers and ranges. The more you insulate the less you have to cool or heat. If you live in a warm climate, consider installing an attic fan that runs on a thermostat or timer. During the summer allow it to run, during winter turn it off. Ceiling fans in rooms that are occupied create the illusion of being cooler, allowing the thermostat to be turned up.I'm not sure of the exact numbers but any thermostat setting on your a/c below 78 is more inefficient so try kicking the a/c up and the heat down. I'm a Florida boy so I can't tell you much about baseboard heaters. I know that anything that heats things up cost a lot in energy.

Consider installing a hot water heater timer. Commonly called a "Little Grey Box". Whenever your water heater is not actually being used it is still heating the water. A big waster. Once installed set the timer to cycle the water heater off during times when you commonly don't use it. Overnight,when your at work etc....

Somewhat antiquated, but a clothesline always uses 100% less energy than a clothes dryer. :) Short of this, try to fill the dryer all the way and make sure your dryer vent and lint trap are clear.

Microwaves draw 1/3 the energy of a range and run for 1/10 of the time. Microwave as many things as you can. In our house we have started microwaving canned veggies and boxed side dishes and such.

These are the big ones I've done at my house. A lot of the other things seemed to be more work than they are worth. Some actually end up costing you more if you don't own the house for decades.

There are many sites you can visit such as your local power company and possibly your local government pages.

Good luck. I'm in the same boat with the high power bill.
