Electronic etankless Water Heater: Design and developed for homers, apartment and anywere hot water is needed. Electronic etankless Water Heater: New Titan-SCR4 Developed for larger home applications and for northern climate In this day and age of $3.00 gallon gas, electrical companies raising rates, oil line disruption and global instability, energy costs are unpredictable. The United States, working with the DOE is trying to get s to save on their electrical use both for their own good and for the good of planet earth. Tank water heaters are constantly using electricity even if you are not needing that hot water. It would be like running a stove all day because you are going to cook, or leaving your TV on until you are ready to watch it. No one would do this, but millions of home owners let their water tank run all day without even thinking about it and wonder why they have a $500 or higher electric bill. Because of this inefficient process, a 60-gallon tank only has 40 gallons of useable hot water. The other 20 gallons are lost as cold water is added to the tank during the usage process. In addition, a conventional tank heater is constantly radiating heat (loss), which also contributes to the re-heating rate and energy consumption of the tank. This type of heat loss is often referred to as "stand-by" heat loss. Amazingly, by eliminating stand-by heat loss alone, energy consumption can be reduced from 20 to 30%! Hot Water Energy Conservation Heating water in a conventional hot water tank accounts for up to 25% of the average household energy use. A leak of one drip per second can cost you $1.00 per month, 2 drips $2.00 and so on. Installing aerators in faucets and low flow shower heads can save a significant amount of hot water. But that conventional water heater continues to turn on and off day and night, heating and reheating the same water. On Demand Water Heaters One way to significantly save on domestic hot water bills is to use a hot water on demand water heater. A conventional hot water system heats water in a tank to a specified temperature. As heat is lost from the tank, the water is reheated until it reaches the specified temperature again. For most of the day and night the water in the tank is not used, but it loses heat continually. Hot water on demand water heaters eliminate this inefficient, costly problem by heating water only as hot water is needed – hot water on demand. Bacterial Respiratory Disease Health Advisory One significant health advisory is a bacterial respiratory disease similar to pneumonia called “Legionelia pneumophila” or more commonly “Legionnaire’s Disease.” Thousands of cases of Legionnaire's disease occur in the U.S. each year. Most often striking smokers, the elderly, and those with chronic respiratory problems or compromised immune systems and 15% of the annual cases are fatal. Causes A 1984 study (Ciesieki et al) reported that the bacterial cause of Legionnaire's disease (Legionelia pneumophila) is capable of colonizing in hot water systems maintained at 115° or lower. Many consumers, in an effort to lower their utility bills are lowering the regulated temperature of their hot-water tank, not realizing they are in effect running a greater risk to their health and the health of their family. The 1995 ASHRAE ( Society of Heating, Refrigerating and Air Conditioning Engineers) Applications Handbook notes that "segments of service water systems in which the water stagnates (e.g. certain sections of storage-type water heaters) provide ideal breeding locations for Legionelia pneumophila bacteria.” For all these reasons it must make sense by now to switch to a etankless water heater and it makes even more sense to purchase the industry standard and technology-setting Titan Electronic etankless Water Heater. What are the required amperage and voltage and maximum Kilowatts? Is it single phase or three phrase? Single Is it UL approved? Yes, compliance # 499 Does it meet ANSI standards? Yes, ANZI-Z, 10.03. What is the warranty? Ten years on casing; One Year on components. What is the expected life of the unit? Approximately 15-20 years Is it safe for children? Yes, infinitely safer than conventional hot water tank systems. There is no tank with pressure to create potential explosion, no flames, and it will not engage from leaking faucets.

TITAN Electronic etankless Water Heater is the answer. Here are some before and after pictures so you can see for yourself the space saving you can get. How etankless Water Heater work Demand (etankless or Instantaneous) Water Heaters Demand (etankless or instantaneous) water heaters provide hot water only as it is needed. They don't produce the standby energy losses associated with storage water heaters, which can save you money. Here you'll find basic information about how they work, whether a demand water heater might be right for your home, and what criteria to use when selecting the right model. How They Work Demand water heaters heat water directly without the use of a storage tank. Therefore, they avoid the standby heat losses associated with storage water heaters. When a hot water tap is turned on, cold water travels through a pipe into the unit. Either a gas burner or an electric element heats the water. As a result, water heaters deliver a constant supply of hot water. You don't need to wait for a storage tank to fill up with enough hot water. However, a demand water heater's output limits the flow rate. Typically, demand water heaters provide hot water at a rate of 2–5 gallons (7.6–15.2 liters) per minute. Gas-fired demand water heaters produce higher flow rates than electric ones. Sometimes, however, even the largest, gas-fired model cannot supply enough hot water for simultaneous, multiple uses in large households. For example, taking a shower and running the dishwasher at the same time can stretch a demand water heater to its limit. To overcome this problem, you can install two or more demand water heaters, connected in parallel for simultaneous demands of hot water. You can also install separate demand water heaters for appliances—such as a clothes washer or dishwasher—that use a lot of hot water in your home.

Water temperature from 105F to 120F is adequate for all practical purposes With more than two decades of great success and customer satisfaction with our Titan-ETH, Titan-ATC, Titan-SCR, and Titan-SCR2, we decided it was time to increase the Titan family of etankless water heaters. Many things have changed in the last 20 years; most notably, in the past most houses had a bathroom with a standard shower and a sink. Today many homeowners and builders are upgrading the bathrooms with new things like body sprayers and multiple showerheads. Also additions like whirlpool tubs have become standard in new constructions as opposed to an expensive remodeling a few years ago. That is the main reason for the need for a bigger capacity etankless water heater development, another reason for a bigger unit is the cold temperatures in northern states where a higher rise in temperature is needed to heat the water instantly. We spent a lot of time talking with our distributors, installers, and customers directly, getting their feedback of what they were looking for. After two years of development and testing, we are proud to say that have achieved a state of the art heater and the newest member of the Niagara Industries family the TITAN-SCR4. Available in three models, the new TITAN-SCR4 comes in 18 KW, 19 KW, and 21 KW; which is ideal for a wide range of applications including residential and some commercial applications.

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 specialized pump, which in combination with the etankless unit can get your hot water to you at less than half the time it would take running the faucet full blast. The etankless 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 specialized pumping system. Water conservation is an important advantage to the pumping system. One such system is the Chilipepper hot water pump. With it you get both water conservation and convenience benefits of faster hot water, and, an un-limited amount of hot water. etankless hot water heaters save energy and thus money. Water heating accounts for 20% or more of an average household’s annual energy expenditures. The yearly operating costs for conventional gas or electric storage tank water heaters average $200 or $450, respectively. Storage tank-type water heaters raise and maintain the water temperature to the temperature setting on the tank (usually between 120° -140° F (49° -60° C). Even if no hot water is drawn from the tank (and cold water enters the tank), the heater will operate periodically to maintain the water temperature. This is due to "standby losses": the heat conducted and radiated from the walls of the tank—and in gas-fired water heaters—through the flue pipe. These standby losses represent 10% to 20% of a household’s annual water heating costs. etankless units are common in Japan and Europe. They began appearing in the United States about 30 years ago. Unlike "conventional" storage tank water heaters, etankless water heaters heat water only as it is used, or on demand. A etankless hot water heater has a heating device that is activated by the flow of water when a hot water valve is opened. Once activated, the heater delivers a constant supply of hot water. The output, however, limits the rate of the heated water flow. Selecting a etankless Water Heater Select a based on the maximum amount of hot water to meet your peak demand. Use the following assumptions on water flow for various appliances to find the size of unit that is right for your purposes: Faucets: 0.75 gallons (2.84 liters) to 2.5 gallons (9.46 liters) per minute. Low-flow showerheads: 1.2 gallons (4.54 liters) to 2 gallons (7.57 liters) per minute. Older standard shower heads: 2.5 gallons (9.46 liters) to 3.5 gallons (13.25 liters) per minute. Clothes washers and dishwashers: 1 gallon (3.79 liters) to 2 gallons (7.57 liters) per minute. Unless you know otherwise, assume that the incoming potable water temperature is 50° F (10° C). You will want your water heated to 120° F (49° C) for most uses, or 140° F (60° C) for dishwashers without internal heaters. To determine how much of a temperature rise your need, subtract the incoming water temperature from the desired output temperature. In this example, the needed rise is 70° F (39° C). List the number of hot water devices you expect to have open at any one time, and add up their flow rates. This is the desired flow rate for the water heater. Select a manufacturer that makes such a unit. Most etankless hot water heaters are rated for a variety of inlet water temperatures. Choose the model that is closest to your needs. As an example, assume the following conditions: One hot water faucet open with a flow rate of 0.75 gallons (2.84 liters) per minute. One person bathing using a shower head with a flow rate of 2.5 gallons (9.46 liters) per minute. Add the two flow rates together. If the inlet water temperature is 50° F (10° C), the needed flow rate through the heater would need to be no greater than 3.25 gallons (12.3 liters) per minute. Faster flow rates or cooler inlet temperatures will reduce the water temperature at the most distant faucet. Using low-flow showerheads and water-conserving faucets are a good idea. Some types are thermostatically controlled. They can vary their output temperature according to the water flow rate and the inlet water temperature. This is useful when using a solar water heater for preheating the inlet water. If, using the above example, you connect this same etankless water heater to the outlet of a solar system, it only has to raise the water temperature a few degrees more, if at all, depending on the amount of solar gain that day. Gas and electric models. etankless Water Heater Enjoy endless showers, save space, energy, money. What is a etankless water heater? Conventional water heaters heat water slowly and constantly throughout the day and store the heated water in a large tank so there is hot water available when you need it. Unfortunately, even with the best insulated tanks, much of the energy it uses to heat the water is slowly lost throughout the day. etankless water heaters, which are also commonly referred to as "instant" or "on demand" water heaters, heat the water only as it is being used. When you turn on a hot water faucet, the heater activates and stays on until the water is turned off. etankless water heaters not only save energy, but they never run out of hot water. The best etankless water heaters on the market feature sensors and a microprocessor that ensure a precise output water temperature is maintained regardless of changes in water flow rate, pressure, and incoming water temperature. While the original etankless water heaters were primarily used for point-of-use applications only, modern high-output etankless water heaters are suitable for whole house use as well as a wide range of commercial applications. Since etankless water heaters eliminate the standby energy loss from the storage tank, they can your water heating costs by up to 50%. Furthermore, they have much longer warranties, take up less space, and, of course, they never run out of hot water! Learn More: The etankless water heater concept and benefits. How does an electric etankless water heater work? When a hot water faucet is turned on, a flow sensor in the heater detects that the water is moving and turns on a bank of heating elements. The water passes over the heating elements, usually in series, and exits the heater at the desired temperature. Since etankless water heaters do the entire job of a conventional tank-type water heater in just seconds, they require very high powered heating elements. In more sophisticated units, a collection of sensors and a microprocessor will control the output water temperature to ensure that a precise output temperature is maintain during operation. When the water is turned off, the unit turns off completely and consumes absolutely no power again until a hot water faucet is turned on. While the basic premise is the same, the performance difference between a lower quality unit and the best units on the market is dramatic. Selection of a model appropriate to your application is very important. As noted above, not all etankless water heaters are created equally. Careful selection of both brand and model is important to ensure that the heater will meet the requirements of your application. The most important distinction between models on the market today is if they use power-modulation technology (sometimes referred to as flow modulation) and thermostatic controls. These technologies are necessary to ensure that the output water temperature of the heater remains constant despite changes to the incoming water temperature, pressure, or flow rate. Without this technology, the water temperature can fluctuate significantly especially when a second faucet is turned on when the unit is running, a toilet is flushed causing the pressure to drop, or if you get your water from a well (the water pressure in your expansion tank changes). Without this technology, it can also be impossible to properly regulate temperature to a safe, usable temperature when trying to find a power setting that accommodates both your low flow rate and high flow rate faucets. Unfortunately, many manufacturers advertise that they use this more advanced technology, but in reality, they do not, or if they do, they use a rather crude form of the technology. The good news, is that a small number of units on the market have the necessary flow-based power modulation and thermostatic control technology to maintain a precise output water temperature in all situation. Learn More: Compare etankless water heater technologies Why should you choose an etankless? First and foremost, the etankless water heater features the most advanced microprocessor-controlled power-modulating (based on flow rate, pressure, and incoming water temperature) and thermostatic temperature control technology on the market today. No matter what the conditions: well water or city water, high flow rates or low flow rates, hard water or soft water, warm climate or cold, you can expect the etankless water heater to maintain a precise output water temperature. Better yet, using a simple, convenient digital temperature selector, you can set the temperature at a level that you find most comfortable. The etankless water heater is built to last. Made in the USA with quality components - you won't find a cheap plastic case and plastic heat exchanger in an etankless! The etankless features a sturdy aluminum case, attractively finished in a white enamel paint, and copper heating tubes in the heat exchanger. The manufacturer is so confident in its design that it offers a lifetime 100% parts replacement warranty which is unmatched in the industry. Learn More: See inside an etankless water heater and learn how it works What else should you know about selecting an on demand water heater? Selecting the right instantaneous water heater for your needs is a function of the technology as discussed above, the maximum flow rate of water you will demand, and your incoming water temperature. Applications which require higher flow rates and/or that are in areas of colder incoming water temperature (northerly regions), will require a more powerful model. Learn More: Get a recommendation from our etankless water heater model selector | etankless water heater models / specifications Since on demand water heaters have to apply a massive amount of heating power to the water instantly, they have very large heating elements. Correspondingly, they require a larger electrical service than most conventional heaters, so it is important to make sure that your home has sufficient electrical service to supply its needs. Learn More: Confirm electrical requirements The first inclination of many homeowners is to purchase a gas etankless water heater if they have had a conventional gas tank-type water heater in the past, or if they are building a new home, since the common belief is that gas is cheaper. When it comes to etankless water heaters, this is often not true, especially when all the costs are taken into account. Electric etankless water heaters cost only a few dollars per month more than a gas etankless heater to operate based on today's energy prices, they last longer, have better warranties, are more thermal efficient (98%+ vs. 80-85%), take up less space, require less maintenance, and cost dramatically less to buy and install, as compared to a gas etankless water heater. Gas etankless heaters are extremely expensive to install due to the onerous venting, fresh air supply, and gas line requirements, not to mention their higher original product cost. As well, it important to remember that etankless water heaters can last well over 20 years - since natural gas prices are rising at a much higher rate than electricity prices, it is widely expected that a etankless electric heater will actually be cheaper to operate than a comparable gas unit in just a few short years. etankless water heater models and specifications electric etankless water heaters are the most sophisticated thermostatically-controlled on demand, instantaneous water heaters available on the market today. offers 7 models ranging from 11 to 27 KW in power, to meet a wide range of point-of-use and whole house, as well as commercial applications.
