Recent increases in energy costs have led to increased interest for cost saving appliances. New 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 efficiency 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.
Energy Saving Water Heaters
It is a fact well-proven that water heaters are one of the best users of energy in a household. Whether you are out looking for a water heater, or are looking for a new one to replace your old unit, make sure you consider the energy consumption of water heaters and how this affects your bills. Aside from choosing a water heater that does not consume too much energy, you can also save energy once you install any kind of water heater you chose.
First of all, if your water heater is old enough, you should start thinking about replacing it. Don't wait until it breaks down. This will put you in a rushed and pressured situation where you have to choose a water heater in such a short time. This is not good, since choosing a water heater should take time. Also, in case you have some problems with your old water heater, you can take that into consideration when you choose a replacement. Then, when you're out shopping for a water heater, don't go right ahead and buy the cheapest one you can find. The initial price you pay for a water heater is not what matters. The operating costs are more important. Think long-term, not short-term.
Also, once you bring home that water heater, don't go and install it just like that. There are still plenty you can do to save energy, such as placing insulating jackets around the tank and the pipes. This will help save energy and costs by reducing the amount of heat that gets lost through the walls of the tank and the pipes as the water is stored there. Insulating jackets are way cheaper, considering that using them can reduce your energy consumption by up to 40%.
Here's another tip, and one that you won't instantly think about when your attention is all on your water heater. Well, you must be forgetting that your water heater works directly with your shower equipment. The amount of water that comes out of your shower heads affect your water heater's energy consumption. Aside from insulating your water heater, you also have to make some revisions with your shower equipment. Consider installing shower restrictors that can limit the amount of water that gets through your shower head. The less water you consume, the less heating the water heater needs to do. And this equates, of course, to lower energy consumption and, yes, less expenses that you need to pay.
Now you're ready to go on and install your water heater. Once it's up and running, however, you should still exert some effort to save energy. There are two surefire ways to do so. First, lower the water heater temperature while you're using one. This can help save some energy. However, the best thing you can do is still to conserve water as much as you can. When you conserve water, you can never go wrong.
Of course, there are a lot more you can do. However, the tips enumerated above are the easiest and cheapest ways to save energy when you're using water heaters. After all, in the effort to save on energy consumption of your water heater, you should not waste your own energy on difficult methods and techniques when you can save a lot of energy using the hassle-free tips above.
