Tankless Water Heaters

In the past 10 years, tankless water heaters become more common in the United State. In

order to understand why the tankless water heaters become more prevalent, it is important to

understand the disadvantages for the tank- type water heaters. These traditional heater systems

have a large tank that will be holding approximately 40- 80 gallons of water and continuously

keep heating the water in 120 to 140 degree Fahrenheit. The energy used to keep the water in a

certain of temperature even when the owner is not using is called the standby heat loss. Installing

a tank-type water heaters will not taking away the usable area, but also increasing your utilities

bills.

Instead of heating the water 24 hours, tankless water heaters generate hot water when you

need to use it, and that can help minimize the utilities bills, as well as the environmental impact.

Tankless systems are using natural gas, propane or electric to operate the system, and the system

will generate heat by using an extremely powerful heat exchanger. The heat exchanger will

activated once there are incoming flow water and will transfer the heat that has generated by the

burner to the water that is coming out from the faucet. In this way, when the owner turn on the

hot water tap, the supply water will be circulate through the activated exchanger by the copper

coil, which will able to provide hot water as an output. Tankless water heaters have two

assortments, these are include the “point of use heaters” and “whole house heaters”. Comparing

these two tankless system, the “point of use heater” is a smaller system and will only able to

support two outlets in a role. On the other hand, “whole house heater” is a larger system and

more costly, however it can support more outlet at one time. Depends on the usage of hot water

and the owner’s demand of hot water usage, known as the hot water flow rate, and decide which

tankless system will suit the best.

Some advantages for the tankless heaters is increasing the energy efficiency, usable area,

longer lifespan, and environmental friendly etc. Nevertheless, there are some disadvantages that

the owner should consider before switching the system. Since the tankless system do not have

the storage tank to store the hot water in certain temperature, this system is incapable to support

the owner to do multiple activities that is require hot water at once; yet, there are one thing that

can be affirm is using a tankless water heater will never run out of hot water. Another

disadvantages are the additional cost, the cheapest traditional tank-type heaters in the market is

around $300- $400, but for a tankless heater starting price is around $1000, rely on the option of

consumer needs. The initial price is about 3 times more expensive comparing to the traditional

heater. Lastly, tankless system require instantaneous energy support to generate hot water. Tank- type system generally use about 30,000 to 50,000 BTU of energy to operate, perhaps tankless

system require 150,000 to 200,000 BTU of energy to generate the same amount of water and

temperature. Thus, after all of these disadvantages, the tankless system is still one of the best

way to eliminate the wastage for the energy loss and global friendly for the long term usage.

Assess The Impact Of Nonrenewable Energy And Environmental Effects On Carbon Footprint

...of renewable energy sources, such as the most commonly used “green” source known as solar energy. The three main reasons for the use of carbon emissions is for the heating of the air in a home, the heating of water used within the home, and the electricity. A space heater is a heater that heats a space directly, and is unlike a central heating furnace or boiler which heats the house through ducts and pipes. Solar space heaters can be up to 25 or more times more cost effective than regular space heaters. One can earn their money back for these low cost solar heating systems in as little as one year. Water heating systems provide enough hot water for ones usage in their home. There are multiple types of water heaters. They include conventional storage water heaters, which offers a storage tank of hot water. A tankless or demand-type water heater heats the water directly and doesn’t use a storage tank. Heat pump water heaters move heat from one place to another instead of generating heat directly for providing hot water. Tankless coil and indirect water heaters use a home’s space heating system to heat water (Krigger, J.; Dorsi, C.,2004). Another option for a water heater, which is more energy efficient, is a solar water heater that uses the sun’s heat to provide hot water. The third type of energy usage is through solar photovoltaic modules, mostly commonly referred to as solar panels. These modules capture the sun's energy using photovoltaic cells. These cells don't need direct...

Singing In The Shower Research Paper

...Have you ever noticed the acoustics while you're singing your heart out? They're amazing. You may have thought that was from the water, resonating the sound. But actually, it's not! Sound reflects off of hard surfaces, like the tile and ceramic in your bathroom, and creates a sort of echo. This echo makes your voice sound better because it makes it sound more full. This fullness is what carries your wonderful voice throughout the room, and likely down the hallway as well. At least if you have the type of room mates I have, you know everyone can hear you singing. That's why, when you're singing in the shower, your voice sounds better than if you're singing in your bedroom. Your bedroom has softer furnishings, which don't allow for the sound to resonate as well. My suggestion, if you're going to practice vocal warm ups in the shower, is to install a Rheem Tankless Water Heater. At least that way, you'll never find yourself getting chilly while you're...

The Green Movement

...have been many movements in time but the green movement is the most important movement in time. The green movement is to educate people how to live a life more dependent on natural resources and to seek energy from cleaner sources other then harmful energy choices. There are many long-term effects of going green. For example, improved health, cleaner water, climate change, economic benefits (Duggan 1). There are also negative long-term effects of not going green. For example, natural resources become depleted at an extraordinary rate. If people don’t adopt this movement there might not be any natural resources for the next generation. One of the biggest downfalls of going green is mostly directed towards individuals, businesses and their wallets. Green supplies are generally greater in cost then the traditionally used supplies(Roberts 1). The cost to convert a 2,500 square foot house with green options are energy audit 0-$500 with a one or less year payback, Duct Sealing $1,350 with a 5 to 4 year payback, insulation $2,000-$5,000 with a 5.7 to 14 year payback, Storm Windows $2,500-$4,750 4 to 7 year payback, Tankless Water Heater $1,489 with a 8.5 year payback (1). Even the smallest supplies have a higher cost: Compact Fluorescent light bulbs cost $136 (1) vs. the traditional $40.00 ones. The flip side is that the traditional light does not have a cost payback. One the other hand, there are benefits to the economy. The green movement would create new jobs by requiring new...

By implementing numerous breakthrough technologies into their production systems automakers are continuously working towards a more sustainable and environmentally friendly production process. Throughout our report we highlight major breakthroughs throughout the industry and how they have affected each individual company. By turning their attention to a more lean production process there have been many positive changes to help eliminate waste and reduce the cost of production. These companies are making conscious efforts to not only reduce the amount of waste produced throughout their systems but also how to reuse or recycle the waste that cannot be prevented. For example we talk about how Toyota has developed automated robotics systems to help control the amount of paint that is used during their topcoat operations to prevent the use of excess paint which is normally due to human error, another example is how they are using the paint sludge in the production of other products such as anti-rust paint sprays. We also discuss how the use of returnable metal shipping containers when shipping parts can greatly reduce the amount of wasted packaging materials and wooden creates from going to the landfills every year.

Segmentation

...CHAP TER Market Segmenting, Targeting, and Positioning C O M P E T E N C Y O B J E C T I V E S F O R M A S T E R Y 1. Identify the role of market segmentation in developing a marketing strategy. 2. Identify criteria for market segmentation. 3. Identify common types of positioning strategies. 5 Suppose you’ve created a great new offering you hope will become a hot seller. Before you quit your day job to market it, you’ll need to ask yourself, “Who’s going to buy my product?” and “Will there be enough of these people to make it worth my while?” Certain people will be more interested in what you have to offer than others. Not everyone needs homeowners’ insurance, not everyone needs physical therapy services, and not every organization needs to purchase vertical lathes or CT scanners. Among those that do, some will buy a few, and a few will buy many. In other words, in terms of your potential buyers, not all of them are “created equal.” Some customers are more equal than others, however. A number of people might be interested in your product if it’s priced right. Other people might be interested if they simply are aware of the fact that your product exists. Your goal is to figure out who these people and organizations are. To do this you will need to divide them up into different categories. The process of breaking down all consumers into groups of potential buyers with similar characteristics is called market segmentation. The key question you have to ask yourself when segmenting...
