2006 end of the year, China started to “storage-type
Water Heater
Limit value of energy efficiency and energy efficiency rating “standard-setting work, and endorsed by the National Development and Reform Commission (NDRC), United Nations Development Programme (UNDP), Global Environment Facility (GEF) co-sponsored by the China End Use Energy Efficiency Project (EUEEP) support. June 2007, the National Standardization Management Committee formally approved the “storage-type electric water heater efficiency limit value and energy efficiency rating” project; the end of 2007, after the standard preparation group effort, “storage-type electric water heater efficiency limit value and energy efficiency rating” completion of the development and approval; April 1, 2008, GB21519-2008 “storage-type electric water heater energy efficiency and energy efficiency level limit values”, and is planned for November 1, 2008 into effect. The scope and parameters of energy efficiency evaluation At present, people use the water heater to the main storage-type electric water heater, or thermal, heat pump water heaters are also momentum of rapid development, such as temperature and electric water heater is energy-saving, compact, saving time by industry and other factors concern. In view of the hot type, pump type electric water heater with a storage-type water heater works with assessment targets and big difference, experts and businesses agreed to propose three types of heaters on the development of energy efficiency standards. Therefore, GB21519-2008 “storage-type electric water heater energy efficiency and energy efficiency level limit value” shall be applicable to storage-type electric water heaters and other auxiliary energy use electric water heater. The use of electric water heaters as a supplementary energy sources, such as auxiliary heating with electricity
Solar water heaters
Does not apply to this standard. The standard edition, has specified “no thermal insulation to the water heater does not apply to this standard” (IEC60379 similar description), but considering there are still some production in China in the electric water heater and the shell without any insulation between the products, if there is no insulation to the water heater does not apply to this standard, the standard will not cover this part of the water heater, thus making it a part of the non-mainstream products have storage-type water heater less than control, may cause some negative effects, so the deletion of the Draft for Approval of “no insulation to the water heater does not apply to this standard”, so long as to reach the technical requirements, whether the installation of insulation, What materials, want to add thickness from companies themselves. And storage-type electric water heater energy efficiency-related technical indicators are: the inherent energy loss of 24 hours (24 hours inherent energy factor), the rate of hot water, heating efficiency. In addition, the energy consumption of storage-type electric water heater and use habits of a great relationship, so some energy-saving control technology developed by energy-saving control device for saving energy also play an important positive role, such as high insulation technology, intelligent reservation technology, the temperature insulation technology, layered heating technology, night electrical technology, variable capacity technologies. Most countries with 24-hour energy loss inherent to assessing storage-type electric water heater energy efficiency, energy consumption in Australia in addition to the inherent 24 hours, while also assessing water output rate; the United States is a set of 6 water discharge standard simulation program for evaluation of electricity consumed by storage-type electric water heater efficiency. Energy consumption test methods from the point of view, most of the energy loss inherent in the national 24-hour test method and IEC60379 “Performance measurement of water heater,” similar to the temperature varied, the location of test points are not the same. United States, more unique test method can simulate the use of state power consumption, but the measurement of complex, time-consuming, expensive tests. Through the international standards of research, discussion, and the storage-type electric water heater energy efficiency of the verification test to determine China’s “storage-type electric water heater limit value of energy efficiency and energy efficiency rating” assessment of energy efficiency indicators: 24 hours inherent to coefficient and hot water consumption rate. Energy efficiency test methods Order to maintain and GB/T20289-2006 “storage-type electric water heater,” coherence, energy efficiency standards inherent in the 24-hour energy consumption test methods, hot water output rate of the same test methods as far as possible with GB/T20289-2006, but because GB/T20289-2006 product testing coverage area is limited, and some local representation is not very clear, easily lead to misunderstanding, so in GB/T20289-2006 energy efficiency standards on the basis of improved test methods, including the following points.
If you’ve seen claims that some device is going to slash your electricity bill by 10% to 25%, you may be in for a disappointment. The fact is, these Electric Energy Saving Devices, while they cut measured electricity consumption for some older electrical motors, barely put a dent in most people’s electricity bill.
These devices are usually called Electric Energy Saving Device, power factor correctors, or power saving devices. They contain a capacitor, which is an electrical device that stores electrical energy for short periods between two conductors.
You’ll read sales pages for these devices that refer to improving the power factor of inductive loads. The idea is that voltage on an alternating current line fluctuates in wave form between positive and negative, sixty times a second. A capacitor can improve the power factor (the proportion of current in the wave form that the motor actually uses) so that more of the energy you draw from the grid actually gets used to do useful work, and less gets wasted because it wasn’t needed at that precise instant. (It can be saved in the capacitor and released some tiny increment of time later. )
Devices marketed as Electric Energy Saving Device or power saving capacitors are real, working devices, but claims that they might cut your power bill are misleading. The sellers usually hint at gains of 10-25% but actually guarantee nothing, and in reality your savings may only be 1-5%, not nearly enough to cover the expense of installing one of these units.
There are two main types of electrical loads: resistive loads, such as lights, or anything producing heat; and inductive loads (such as an electrical motor, or anything involving electromagnetism). Unfortunately, these devices only work on inductive loads – typically electric motors – and only those that don’t already have a capacitor built into them. And if you do a load estimate for your house just by scanning all the devices you use and guessing at their wattage and hours of use per day, you’ll soon discover that inductive loads make up a fairly small proportion of your overall load – perhaps 25% or less. (You don’t run your washing machine more than a few hours a week, but some lights are on 12 hours a day or more. ) So the savings you’re being promised will only apply to that small percentage of your total electrical bill.
Manufacturers have been adding capacitors to anything with an electric motor for a number of years, because it’s one easy and inexpensive way to increase energy efficiency of those motors, thereby making the price to efficiency ratio more appealing to consumers. If you own an ENERGY STAR appliance containing an electric motor, chances are it already has a capacitor and you won’t save any electricity on that device with one of these power saving units.
The sales pages for these power saving devices usually hint at potential savings but they don’t actually guarantee any particular level of savings. You’ll see claims of a range: a drop of 10 to 25% in your electrical bills. But if you look closely, you’ll see there’s no guarantee of that. Even assuming you did see a gain of 10 or 25%, how would you know whether the gain came from that or from something else?
Look for the testimonials provided on these sites. Do customers claim to have cut power use consistently month after month while using these devices? Or is there just a claim that power use dropped by X% after the first month? Here’s an interesting scenario: say one hundred people buy such a device and install it in their home.
Since everyone’s power use fluctuates month by month, even if the capacitor does no good at all, some people are bound to see a drop in power use from one month to the next, while others will see an increase. Those who see an increase in power consumption may ask for a refund for their Electric Energy Saving Device. Those who see a small gain will be moderately happy, or at least won’t complain, while the small number who, for reasons unrelated to their energy saving capacitor, see major gains, will write a glowing testimonial. The testimonial gets published, and the person who asked for the refund gets their money back but doesn’t get anything published about how badly the system ‘appeared’ to work for them. (We’re assuming, of course, that the published testimonials aren’t fabricated. )
Another point in favor of this scenario (namely, where the small percentage who miraculously cut energy costs while using such a device, are the ones whose testimonials get published) is the fact that often people create the result they want to see. For example, it is well established that one of the best ways to get people to cut their electricity usage is to get them to measure their electricity usage. That’s exactly what helped my family cut our electricity usage by 50% or more: measuring our usage with an electrical power monitor (a much cheaper device, by the way, that will save you far more electricity than a power factor corrector) allowed us to see where we were wasting electricity, and we easily cut most of that waste. If you install one of these so called power saving devices expecting it will save you energy, chances are, you’ll start measuring your electricity use on a more regular basis (even just by looking at the outdoor power meter). And chances are reasonably good that your increased awareness of your electricity use will cause you or your cohabitants to be more careful about turning off lights and avoiding other big energy using activities.
Some Electric Energy Saving Device even come with a money back guarantee. That’s great, but again, think of the hundred-customer scenario.
If by fluke (or because they’re more carefully monitoring their energy use, and therefore they subconsciously cut out waste) some people see their energy use drop, they’ll keep the device, and the seller keeps the money. Others who don’t see a gain may decide not to bother asking for the refund (some people feel embarrassed when they’ve been duped) while others will get their money back. Considering that these devices are very cheap to manufacturer, a seller can profit handsomely on a $300 to $700 device even if 90% of the devices are returned. (And of course the returned devices may be redeployed to others. )
As far as testimonials go, look closely at the context. One website included a testimonial from a company that ran several large water pumps. Of course, these pumps are probably inductive motors that do not have their own built in capacitor, so significant savings should be expected.

The media are full of news about electric cars. The $100,000 Tesla electric sports car is going to be sold soon, automakers are falling over each other to announce new electric vehicles, and entrepreneurs across the world are jockeying for venture capital.
Petroleum prices have jumped during the last year and everybody is feeling the pain at the pump. Not a single soul is concerned about filling up the batteries of his next electric car with electricity. After all, you just plug the car into the next receptacle and there seem to be no appreciable costs.
Joe owns a Corvette, a high performance car manufactured by General Motors, which according to the car manufacturer drives 25 miles per gallon.
Joe’s monthly commute is 1000 miles, he drives very carefully, and actually achieves 25 MPG on his daily trip going to work and running errands. At $4. 00 per gallon at the pump he is paying $160 for gasoline every month.
Joe is thinking about buying the Tesla, an electric sports car. He tried to find the cost of electricity for driving this car. He could not find any data anywhere. Joe knows that he must explain to his wife why he needs to save energy and money before buying the Tesla, a new, very fast electric sports car.
The Tesla will accelerate faster than his Corvette. There is no doubt that an electric vehicle can have a faster acceleration than a gasoline car. Electric motors and liquid fuel engines are just two different devices converting electric energy or petroleum fuel energy into mechanical energy. Electric motors can generate much higher torque at the wheels at much lower turning speeds.
In comparison, electric motors will have several shortcomings, too. They certainly will emit more pollutants and more carbon dioxide as long as coal is used for producing electric power. Overall energy efficiency of the electric car, from power plant to the road, is still worse than that of a modern automobile propelled by an advanced combustion engine.
The biggest drawback of electric cars is the small number of miles they can drive after a complete recharge. Additionally, the charging of an empty electric battery will take forever, high performance batteries are expensive, and will only have a limited life expectancy.
What about energy costs for driving an electric car compared to a gasoline powered car? Both vehicles will have to store energy. The electric car stores electric energy in its battery, the combustion engine powered car stores energy in the form of gasoline or diesel fuel in its fuel tank.
Now let us take a comparative look at the cost of storing and paying for enough electric energy or liquid fuel energy to drive 100 miles. Let us assume that both cars will have the same power requirements to drive 100 miles. In this respect the match-up between Tesla and Corvette is perfect. But how do we compare prices at the gas station with utility costs at the receptacle?
Energy contained in gasoline can be converted into mechanical energy only at the limited energy conversion efficiency of a typical heat engine. The Corvette engine will have an energy conversion efficiency of about 35%. (Fuel fired engines may eventually reach 50% peak energy conversion efficiency after decades of future advancements). Conversion efficiency of electric power from the receptacle into stored energy first and into mechanical energy later is much higher at about 85%.
The energy content of gasoline is 131 MJ/gallon (megajoule per gallon). For driving 100 miles the Corvette will burn four gallons of gasoline or 524 MJ/100 miles. Only 35% of the energy in gasoline or 183 MJ will be used to propel the Corvette. This is the mechanical energy transmitted to the rear wheels of the Corvette. Virtually the same amount of energy must be transferred to the wheels of the electric car, the Tesla. Both cars are very similar in size and driving characteristics.
However, the Tesla has to take a little more energy from the receptacle because the charging, storing, and discharging of electricity in the battery experiences energy losses. These losses are about 15% of the electric energy taken from the receptacle and will not be available at the wheels. The Tesla owner will, therefore, pay 1. 15 times as much to get the same energy to the wheels as the Corvette or 211 MJ per 100 miles. Electric energy is priced in the form of dollar per kilowatt hour or $/kWh. The average price of electricity in the US is $0. 09/kWh. The factor for converting energy measured in MJ to energy measured in kWh is 0. 2778 kWh/MJ.
To drive 100 miles, the Tesla will consume 58. 6 kWh of electricity at a cost of $5. 28. The Corvette will consume 4 gallons of gasoline at a cost of $16. Now we know that the Tesla will save about $10 per 100 miles or $10,000 over 100,000 miles.
The Tesla will cost $100,000. The Corvette is priced from $50,000 to $75,000. Guess who gets the square deal with the roar of the engine as a free bonus.
