Energy Star Now Rates Water Heaters
In an attempt to address this significant percentage of energy consumption, DOE has developed ENERGY STAR criteria for water heaters, the last major residential appliance that the program has not addressed. According to DOE projections, Americans are expected to save approximately $780 million in utility costs while avoiding 4.2 million tons of carbon dioxide emissions by the end of the fifth year in effect.
Five categories of residential water heaters will be eligible for Energy Star labeling - high-performance gas storage, whole-home gas tankless, advanced drop-in or integrated heat pump, solar and gas condensing. The new Energy Star criteria go into effect in 2009.
"The Energy Star program empowers consumers to make smart energy choices that will save money and energy, and reduce our carbon footprint," said DOE Assistant Secretary for Energy Efficiency and Renewable Energy Andy Krassner. "Expansion of the Energy Star program to include water heaters will give Americans yet another way to more efficiently use energy in their homes and, in the interest of increasing energy security and addressing climate change, help further the President's goal of fundamentally changing the way this nation uses power."
By leveraging the established value of the Energy Star program, DOE hopes that manufacturers will focus on developing more efficient technologies and that consumers will recognize that Energy Star water heaters will deliver similar or better performance than conventional models while using less energy and saving money. According to an April 2008 report released by the Environmental Protection Agency (EPA), the Energy Star label favorably influences more than 70 percent of households, up from about 50 percent in 2003.
More than 9,000 organizations have joined Energy Star as partners committed to improving the energy efficiency of products, homes and businesses. The Energy Star label now appears on more than 40 kinds of consumer products. A.O. Smith, industry leader for more than 70 years, has engineered a full line of Energy Star water heaters to meet the hot-water needs of households while benefiting budgets and the environment.

Build solar water heaters
Solar water heaters are the most scientific as well as developed way to heat water. The electric water heaters are outdated and the solar water heaters will soon be taking their places, no doubt. And why not? A solar water heater helps us not only in reducing our electricity bill, but at the same time, it helps us in giving our part to save our environment and surrounding.
Types of solar water heater
Solar water heaters are of generally two main types, classified on the basis of their making status. They are
1. Ready solar water heaters : these are those kinds of solar water heater that are already manufactured and just need to be installed.
2. Build solar water heater :these are those kinds of solar water heaters that are made at home or anywhere by any individual following a particular guide or manual.
Build solar water heater
By making your solar water heater, you are able to reduce the electricity bills. And at the same time, the investment also decreases compared to the readymade solar water heaters. It is very easy to build solar water heater. All it needs and requires are few things from the hardware store, few project schematics and that’s all. Only by assembling these things, you can make your own solar heater. The time required depends on how big solar water heater are you making. Bigger the heater, more it is going to take time.
Build solar water heater for home
There are few options provided while making a solar water heater. Either it is made for use at home or at some other place.
If it is made for home, then all you need to do is to set up a solar panel at your house. This is to be set where it can receive maximum sunlight. And then this solar panel is connected to the existing heating system. Also a high capacity battery can be installed for the back up purposes. It can help you when the sun is not out. If you don’t have a heating system, then you should go for a ‘real time solar water heater’. It heats the water without storing it.

On-Demand Water Heating from Efficent Tankless Water Heaters
With the rising energy costs there has been an increase in interest for energy saving appliances. Efficent "tankless" water heaters have become very popular for their capability to heat hot water on demand, with no storage tank required. Instead of holding water in a traditional water tank, they circulate the cold water through a series of electrically heated coils that warm the water as it moves pass this heat source. This newer process of warming water requires more expensive equipment than the conventional water heater, but this money is regained in the long term with energy efficiency savings. The energy savings is mainly gained from no longer needing to heat an entire tank of water.
Since the tankless water heaters do not store hot water but rather constantly heat water as it is demanded, they do not run out of hot water. There is one exception, to this "endless" supply of heated water. The flow rate is limited. In other words if you simultaneously use more water than the flow of the water heater (i.e. 3 people showering at one time) you will receive unheated water.
Since conventional water heater stores the water together in a large tank it is able to provide water at a set temperature. Tankless water heaters differ in this aspect since they are dependent upon the incoming water temperature and the flow rate. The incoming water temperature can vary greatly from summer to winter. The capacity of a tankless water heater is generally measured by how many temperature degrees it can increase water temperature by gallons per minute (gpm). Most tankless water heaters are powered by gas to better handle the heat output and response time required. These gas powered water heaters require proper venting, normally more venting than the older, conventional water heaters required. If you are replacing a conventional electric water heater tank, you may want to add a power vent in the side of the wall. This would be the less costly alternative if there is no existing roof vent. Some of the smaller and more portable single-fixture units are powered electrically.
