How An Indirect Water Heater Adds Convenience
by Korbin Newlyn
plug itWhen the cold winter months come around there is nothing more frustrating than running out of hot water. This is where an indirect water heater is most of effective. It is effective because it relies on the heating system throughout the house. Because of this it is obvious that this type of device is best utilized in climates where it is cold for extended periods of time of the year where the heating system is used on a regular basis.
How an Indirect Water Heater Functions
Hot water that comes from the house boiler is collected in a tank that is insulated which maintains its circulation until it is needed. In this fashion the household ends up saving money as the boiler does not require it to be turned on and off as frequently as it normally would. They also come with an assortment of power controls which means additional savings can be added.
Companies Manufacturing and Supplying Indirect Water Heaters
The Coliex system is an excellent selection if you wish to heat a very large amount of water at once or you require large volumes of hot water. These tanks are constructed of stainless steel which means they are highly efficient at storing hot water and holding in the heat. They're also very well built to withstand any type of accidental damage that may happen.
Amtrol is an additional manufacturing company that focuses on indirect water heater's. They have an assortment of systems and models that will suit each person's needs.

Tankless Water Heaters - Some Like It Hot : Water Boiler store
Tankless Water Heaters - Some Like It Hot!
by Ivan Cuxeva Jr
plug itTankless water heaters have pros and cons, just like everything else. They can supply an endless supply of hot water, and can save energy.
However, they are limited in the amount of hot water that can be produced at one time and they are more expensive to purchase than a conventional storage type water heater.
They also make it take longer for you to get your hot water, since they don't start heating the water until you turn on the faucet. This problem can be solved by using a demand hot water pump, which in combination with the tankless heater can get your hot water to you at less than half the time it would take running the faucet full blast, and the pump doesn't run water down the drain, so you save not only time, but water as well.
The tankless water heaters also cause an increase in water wastage since you have to let the water run longer to get your hot water. This problem is also solved when using the demand pump.
Tankless water heaters come in a variety of sizes for different applications, such as a whole-house tankless water heater, a source for a remote bathroom or hot tub, or as a boiler to provide hot water for a home heating system.
Tankless hot water heaters are available in propane (LP), natural gas, or electric models.
Tankless water heaters can also be used as a booster for dishwashers, washing machines, and as a backup for solar or wood-fired domestic systems. You may install one centrally, or you can install one at the point of use, depending on the amount of hot water required. For example, you can use a small electric unit as a booster for a remote bathroom or laundry, or in the kitchen for cooking and instant coffee etc.
Gas units with a standing (constantly burning) pilot light, however, offset some of the savings achieved by the elimination of tank standby losses with the energy consumed by the pilot light.
Moreover, much of the heat produced by the pilot light of a tank-type model heats the water in the tank, heat that is just lost with the instantaneous units.
An alternative to the standing pilot light is an intermittent ignition device. This resembles the spark ignition device on some gas kitchen ranges and ovens. You should check with the manufacturer for models that have this feature.
Small units are usually installed in a closet or underneath a sink, and are usually electric due to the difficulties involved with installing a flue. If the unit is gas, a flue and gas piping will need to be installed, which can cost a significant amount of money. If electric you will probably need 220 volt service run to the location where the unit will be installed, which can also be some what expensive.
Gas-fired models typically have a higher gallons-per-minute output than electric models. The largest gas models, which may provide all the needs of an entire household, are usually installed centrally. The flue required will be larger than that of a gas tank type model.
As with many tank type models, even the largest whole house models may not be able to supply enough for large simultaneous, multiple uses (i.e., showers and laundry).

Is it Important to Use Boiler Water Treatment Chemicals? : Water Boiler store
Is it Important to Use Boiler Water Treatment Chemicals?
by Rob Parker
plug itIndustries in which boilers are used to treat water that is used in production, or as an after product before disposal may question whether or not the use of treatment chemicals is necessary. After all, shouldn’t pure boiling be enough to rid the water of any major solids or pollutants that may be held in suspension?
The answer to this question is no. Even in cases where the influent water is of high quality, such as that drawn from a deep well, it is likely to be “hard†water, in need of chemical treatment. Additional chemicals, of course, will be needed depending on the quality grade of the water used in your industry, and its source. There are several reasons why using these chemicals is important:
Particles in solution may prove abrasive in your systems. No matter how small particles in suspended water are, they have the potential to create some major hazards when run through pipes and equipment. Just think about the damage salt water does in a single summer to boat engines and so on; not only through abrasion but also through corrosion, when salt drops out of suspension and erodes the inner workings of the machine. Any kind of solid can cause the same type of damage to valuable machinery and pipe work in industries, and boiling won’t always remove all particles. In many cases, chemicals are needed to “bond†out the suspended particles.
Contaminated water may lead to contaminated product. Chemical treatment is just another barrier to help avoid any danger of contaminated water. Think of a boiler system as a double wall against water contamination; the first wall is the heated water itself, with the additional defence provided by the chemicals used in the boiler.
When it comes right down to it, the use of boiler water treatment chemicals is good for your company’s bottom line. It prevents the degradation of important machinery and piping as well as providing additional protection against contamination.
Chemicals for treating boiler water are available for any problems that you may encounter from your source, from antifoaming agents to scale and corrosion preventatives and anti-bio fouling solutions. Find out which risks come from your influent source and then make sure risks are addressed through the use of the right treatment chemicals.

Portable Water Distiller : Water Boiler store
Portable Water Distiller
by Joseph Then
plug itA portable water distiller is used to vaporize and condense water. This distiller has a container to hold the water which is to be distilled. The heating element is generally situated below the required water level and spaced from the container’s side. There is also a regulator to maintain the water in the container at the required level. This distiller is equipped with a sensor to sense the air temperature above the water level in the container. There is a button for it to switch off to remove power from the heating element. This would responds to a high temperature reading in the sensor.
This purifying ways can also being done with the help of various filter, water distillers, ionizers and other devices. This portable water distiller is capable of removing the five major categories of water pollution. The portable water distiller is used to remove heavy metals, radioactive contaminants, inorganic salts, bacterial contaminants, and organic contaminants.
Always choose a purification system that is consistent with the lifestyle of your family. This is because home distiller may range up to $300-$700. It is wise to choose wisely because the price is dependent on its size and capability. A portable water distiller is surely a definite step towards health.
To get a completely purified water system that is capable of adequate cell hydration, a water distiller with carbon pre-filtration is the most ideal choice. This is because many water distillers do not require any assembly or installation. In most of these water distillers, just need to fill the boiler with ordinary tap water, plug it into any standard electrical outlet and push the start button to get pure distilled drinking water. It is a very convenient feature as it can automatically stop when the cycle finish.
Every individual have different responses depending on our respective immune system to resist to infections, colds and even chemical contaminants in air or water. Drinking water with impurities may raise the risk of putting your health at risk. This is why portable water distiller is helpful. It helps to clear out water from any impurities that might have harmful effect in the body.
With the availability of small portable water distillers, it is very convenient to bring everywhere you go. There are many kind and type of water distillers and various brands in the market. Spoilt for choice, there are many to choose from and do find the brand and that model that suits your lifestyle.

Human Powered Water Purifier : Water Boiler store
Human Powered Water Purifier
by H2bid.com
plug itDo you have a great idea on how to deliver clean water to disaster victims? If so, the American Society of Mechanical Engineers (ASME) needs your input. ASME recently put together an 'open source' community to design a human-powered water purification system. The goal of the project is straightforward; the team wants to develop a device that provides potable water without relying on an electrical hookup. Such a device has many potential uses ranging from use in the developing world to use after a disaster when utilities and sanitary services have been interrupted.
Great Ideas from Students
The project grew out of a 2007 ASME student competition focused on the design challenges of a human-powered still (boiler) to distill potable water after a hurricane or other natural disaster. The 2007 project asked student teams to design and build a unit that could boil polluted or otherwise undrinkable water then condense the steam to provide drinking water. The competition focused on creating the lightest possible, human-powered boiler and condenser system; ultimately the 2007 competition was so well received that a desire to build a usable system grew from the students' efforts. David Soukup, Managing Director for Centers at ASME said, "This is really a new venture for us. We saw a number of interesting designs [at the 2007 competition] and we wanted to pull the best from them."
Individuals that became finalists during that competition were invited to apply to become part of what is the current design team. Ultimately, ASME selected five student team members and two faculty from the Western Kentucky University who will serve as project managers. The student team consists of William Hagen (University of Miami), José La Verde (Lunds University in Skane, Sweden), Javier Lopez (Simón Bolívar University in Caracas, Venezuela), Zach Pearl (Western Kentucky University), and Ken Ruble (New Mexico State University). Kevin Schmaltz and Robert Choate will serve as the project managers and faculty advisors; both are professors at Western Kentucky University. This group organized and initiated the online, open source community to further refine the team's goals. Soukup said that the team has been holding weekly web conferences where the students share their research and design ideas.
One of the team's important decisions was deciding on the real scope of the project. Soukup told H2Bid that the team's objective is a "compact, easy-to-transport water purifier that would be able to provide a family of four with drinking water for 2 weeks." He went on to say that rather than rely solely on human power to distill water, the team is leaning toward a mostly-human-powered device that takes advantage of solar energy and uses filtration in addition to heating the water.
Online Collaboration Powering the Effort
"One of the trends we see in the engineering field is collaboration, particularly online collaborations. ASME can provide the vehicle to show the value of collaboration for this kind of work," said David Soukup. Interestingly enough, ASME didn't restrict the collaboration on this project to the design team or even to the broader engineering community; instead the collaboration is truly open to all who want to participate. By opening the design guidance to any internet user, the team felt that they would be getting the best input for their design. Some of the early discussion in the online community was focused on fundamental questions such as: What pollutants should be considered? Should the device remove both biological and toxicological pollutants? How clean is 'clean enough'? What sorts of environments will be host to these devices? These types of questions were fundamental in helping the team to refine the scope of the project.
The design team is continuing to use the online community's input to develop and refine their design direction. Taking the community input into account, the design team will design a fully-functional water purification system. Beyond just a concept on paper, the team will assemble and test the device in mid-May at Western Kentucky University. The team hopes to show that the use of community collaboration can result in faster development times and a more complete understanding of potential problems or issues that may affect the success of the design. Additionally, the team hopes to finish with a device that works well in as many situations and environments as are practically possible.
The team has high hopes for where the project might go after the prototype has been built and tested. "We are open to what the next step might be," said Soukup. He went on to add that ASME is eager to hear from the industry about any potential "ideas or opportunities for further collaboration." There is a good chance that the device will be almost immediately useful in a variety of situations around the world. H2Bid will continue to follow the design teams' efforts and will report on the outcome of the project in late May after the testing is complete.
