Energy Efficient Tankless Hot Water Heater

If you are buying a new water heater, this is the right time to switch to a tankless hot water heating system. As you probably know, a tankless hot water heating system will save you money going forward. According to estimates, you can save around 20% to 30% from your water-heating bill. The main argument against tankless water heaters is that they are costly compared to conventional tank water heater

It is true that the initial investment on a tankless water heater is higher than a tank water heater. However, it is also to be understood that the subsequent monthly energy bills will be on a lower side than earlier. In fact, tankless water heaters, at an average, will last five to ten years longer than traditional water heaters.

This ensures that you will continue to save on lower energy bills for a long period, suggesting that your initial investment will be repaid fully in due course. In addition, you should also consider that a storage tank heater would need to be replaced again in about ten years, and you are avoiding that possibility too by switching to a tankless water heater, which has a longer lifetime.

Tankless water heaters are more energy efficient with zero standby heat loss compared to traditional water heaters. They only need enough power to heat the amount of water necessary at any given moment. Also, they never run out of water. Because of their smaller size, particularly electric tankless water heaters, they can be installed anywhere you like. If installed near the outlet, you can save the time lag as well. Since electric models do not produce greenhouse gases, they are also environment friendly.

Another criticism is that, with tankless water heaters, your hot water output is divided among all your household fixtures. True, that can not be seen as a drawback , instead it is an added advantage that the a whole house tankless water heating system can solve all your household hot water requirements. Moreover, most of them come with a remote control system. Further, since it is a tankless, you do not have to bother with tank leakage, flooding and related problems.

In addition, most tankless water heater models are eligible for a federal tax rebate of $300. Seriously, put some thought into these points and take a wise investment decision on a tankless water heater.

Buying Whole House Tankless Water Heaters

As the name suggests, the whole house tankless water heater is designed to serve the hot water requirement of a whole house providing unlimited hot water at different number of fixtures at a time. For example, a single unit can give hot water at two showers or kitchen sink or lavatory or dishwater at the same time. This is a great attraction for large families. The other alternative is the single –point of use units, mostly used by small families.

The main advantage house owners see in a whole house tankless water heater obviously is the low energy cost to run them. One way it saves energy is by saving the standby cost necessary for heating the storage tanks in traditional water heaters. In the case of tankless water heaters, be it whole-house unit or single –point of use unit, there is no storage tank and therefore no standby cost.

Similarly, both the types function by the same principle. That is, the units heat the cold water, as it enters by a heating element or the heat exchanger. When water enters, the flow of water activates the heat exchanger and when the flow stops the heat exchanger gets deactivated.

So, the tankless water heater operates of its own, heating water as and when needed only. This is unlike a traditional water heater where heating water is a continuous process and therefore more expensive.

The heating exchanger in a tankless water heater can be electric resistance heating coils or gas fired burners. Usually in whole house tankless water heaters, heating exchangers are gas fired burners as they have more heating capacity and therefore more cost efficient than electric resistance heating coils .

Although the whole house tankless water heater is a big advantage to large families, it has certain weaknesses as well. As the number of fixtures is more in the case of whole house tankless water heaters, there is a great impact on the overall flow rate. Because, the volume of water required to heat is large in whole house units.

The flow rate is also influenced by the temperature of the cold water entering the unit and exiting the unit. All this necessitates the use of more than one whole house unit in very large families. As whole house tankless water heaters are costlier than single-point of use tankless water heaters, this force large families opting for whole house tankless water heaters to shell out large amounts for their water heating needs.

Energy Efficient Water Heaters


In this article I will cover energy efficient water heaters
Energy efficiency is a hot topic right now and new technologies are being introduced everyday. We recommend that you do not wait until you need a new water heater to do your research.

You may find yourself buying what ever is available, instead of what is best! This is not a good plan since your hot water heater is the biggest waste of your energy costs. So do your research now, and double check it just when you are ready to purchase.

Consumers have a tendency to purchase their heater based on size. Actually the First Hour Rating (FHR) is more important to consider.

The FHR represents the amount of hot water that the unit will deliver during a busy hour. Estimate your family’s usage during the peak hour usage and find a unit with a FHR that will cover it.

The most energy efficient water heaters are generally gas fired. Electric resistance is an expensive way to generate heat and not as environmentally friendly. Before you make the final decision, check with your utility company to see if they have any incentives that may make electricity more attractive.

Besides the standard gas and electric energy efficient water heaters there is the indirect water heater. This type is only for consumers who have a boiler. It uses your boiler as its heat source. This type of system eliminates a lot of the heat loss through the flue, as associated with the gas fired heaters.

The next type is a heat pump water heater or desuperheater.  With this type the electric is used to move the heat from one place to another instead of actually creating it. The heat source comes from the heat in the outside air or the area where the unit is located. This type is not very common and harder to find.

Solar water heaters use the sun to heat your water. They are very expensive and hard to calculate the cost because there are so many factors that affect it. These would include the amount of sun, where you live, which way your roof is facing and the amount of hot water that you use. If everything is right though they offer a virtually cost free hot water from a renewable energy. Seems like solar power was hot, then cold and now it seems to be making a comeback. There seem to be many opinions out there for and against solar power. The drawback is that you must have some type of backup system for when there is no sun.

So the bottom line is that this is a very big decision. Make sure that you use every available resource to do your research before you spend your hard earned money. If you make a mistake, you will be paying for it for a long time!

Energy Saving Gas Tankless Water Heater


Storage Tank Water Heater History
The Water heater is one of neglected appliances in homes, usually tucked away in some corner of the garage. We don’t pay much attention to it until it breaks. It has been around in its current form for a long time. It was invented in the 1889 by Edwin Ruud and it hasn’t changed much since then.

It consists of a 40 or more gallon cylindrical container with a gas burner or sometimes an electric element. It heats the water slowly and keeps it hot all the time. Its burner has a pilot light that is burning gas all the time and the main burner comes periodically into action to heat the water again because the water in the container has cooled off.

Well, that goes on day in day out even if the water is never used. That is because the water loses its heat to the surrounding. It is like having a kettle full of water on the cook top all the time.

The newer tank water heaters are better insulated than before to reduce the standby heat loss but never the less they lose heat and the water must be constantly reheated. In today’s times where energy has become expensive and will become even more that is a total waste of energy and money. It burdens the environment even unnecessarily and contributes to earth warming and climate change.

Hot Water Gas Heaters

When people think about a water heater, most imagine a hot water gas heater. But this is only one type of heaters currently available on the market. Modern technology offers other varieties such as solar, electric and instant heaters. How does a gas heater stand against the modern heaters? Are there any serious reasons for you to switch to a different type of heater, or is gas still the best?

Other types of water heaters

Hot water gas heater is not your only option. There are several other heaters, you can use where gas supply is not readily available. For example electric water heater is in high demand and many people prefer electric to gas. However, gas water heaters are still the most popular and majority of people who buy heaters, buy gas water heaters.

Instant hot water heaters

A recent invention is a tankless water heater. This type of heater brings you hot water the moment you turn the tap on. As the name suggests tankless heaters have no storage tank for water, they heat it as you use it. They are also called instant heaters. This is very much appreciated by many people because now they can take bath anytime without having to worry of switching on the geyser 20-30 minutes ahead of time. Also if many people take a shower one after the other, an instant water heater is a great advantage - you will not run out of hot water.

Solar water heaters

Solar water heaters are also a great advance in technology. With light capturing panels installed on your roof, solar heaters use the sun as an energy source. So in theory, solar heater is free all together, apart from the initial installation cost. However, the initial cost is very high. And also if there are several cloudy days, your solar water heater stops working.

And still most people prefer gas water heaters, because it is simple and also economical. It is really much cheaper than any of the electric or solar heaters, including tankless varieties.

Gas water heater disadvantages

There are some drawbacks to gas hot water heaters. First, compared to electric heaters they are slow. Second, you can only use natural gas heater where there is gas supply. But on the bright side, if you want your water cooler, you can turn gas heater down straight away, and get the exact temperature you like.

For example, you can run a dish washer, shower, and more using the same gas tankless hot water heater.  Unlike a traditional hot water heater, you can have a endless supply of hot water for your shower or other hot water appliances.  One of the best things about this is that you do not need to run your gas bill up using energy that you do not need.  Instead, the Bosch Aquastar will only use energy when you are using the hot water in the tank.  Other than that, your water will remain warm, but it will truly warm up when you need it most.  Bosch will supply you a constant supply of hot water and only turn on when you are using it!

While the Bosch Aquastar is a great model for people who need a large solution for their hot water problem.  Takagi gas tankless water heaters are great for people who either want a large or a small tankless hot water heater.  Takagi has been in the business of water heaters since 1952.  That means that they know exactly what you will need to provide hot water for your home.  Takagi tankless water heaters are both large and small enough to work in any home, apartment or condominium.  The Takagi tankless hot water heater also does not cost as much as the Bosch Aquastar models.  You do not need to worry about how much gas you will use, as the Takagi models are very energy efficient, sometimes even more so than the models that Bosch offers.  

Another thing that is important to consider when you are dealing with a tankless water heater is how much water you are using.  The large model of the Bosch Aquastar can provide you with a large quantity of water that is great for taking a shower and running multiple appliances at the same time.  However, if you are living by yourself, or do not need to run many appliances at the same time, the Takagi tankless water heaters can provide you with the hot water that you need in order to take a shower, run your dishwasher or simply wash your hands.
