what is the recommended temperature setting for a tankless water heater
For a tankless heater, this means that there is a smaller draw of hot water at 125 degrees and a larger draw of cold water. Since the draw of hot water is reduced, the amount of gas to heat the smaller flow is also reduced.For washing dishes or laundry, the higher temperature will cost you more money as the temperature may not be offset with cold water.ince the draw of hot water is reduced, the amount of gas to heat the smaller flow is also reduced.

cost of an immersion heater per hour
A typical electric immersion heater for you hot water tank is 3kW (Kilowatt). With a typical daytime electric tarriff of 15p per kWh (kilowatt hour), it costs 45p per hour to heat your hot water with an immersion. Heating with gas will be significantly cheaper.Gas is currently 5p per kWh and assuming you have an old inefficient boiler running at 80% efficiency, it will be costing you 7p per kWh.ssuming you are paying 15p per kwh this equates to 15p per day or £54 per year. If the immersion is on just before you need the hot water rather than heating up hours before then the standing losses will be reduced. A simple way to save £54 is turn the immersion on 2 hour before you need the hot water.
If you leave your immersion always switched on, think about when you use hot water. If you have a well insultated cylinder it will lose about 1 kwh per day. That is it loses the heat equivalent to a 1 kw heater being on for 1 hour. Assuming you are paying 15p per kwh this equates to 15p per day or £54 per year.If the immersion is on just before you need the hot water rather than heating up hours before then the standing losses will be reduced.A simple way to save £54 is turn the immersion on 2 hour before you need the hot water.ssuming you are paying 15p per kwh this equates to 15p per day or £54 per year.

how hot does taco pump motor get
Taco pumps maximum temperature is 240 F Taco 00 series cartridge circulators are designed to run at temperatures up to 240 degrees F continuously. That is one of the most frequently asked questions for Taco. The motor is cooled by the water being pumped (in most cases the water is 180 degrees) so the pump skin temperature can far exceed 200 degrees. This is normal, and not a detriment to the pump. If you have any additional questions about the Taco 007, please call me direct.
• engine-driven fuel pump • fuel control unit (FCU) • torque limiter • flow divider and dump valve • fuel manifold and nozzles. The engine's boost pump draws fuel from its nacelle tank and provides it under pressure to the oil-to-fuel heater where it is heated by warm engine oil. As fuel temperature increases toward 70°F (21°C), the heater's bypass valve admits less oil into the heater. Once fuel temperature reaches 90°F (32°C), the bypass valve closes completely. Fuel flows from the heater to the engine-driven fuel pump. Before entering the pump, fuel flows through a strainer. If the strainer clogs, a bypass valve routes fuel around the strainer. The pump pressurizes the fuel to approximately 800 PSI before it flows through a filter. Like the strainer, the filter also has a bypass valve. A transmitter between the fuel control unit and

how long does a hot water tank last
Step 6 Check the tank's age Check the age of your hot water tank. Most hot water tanks are warrantied for 5 to 10 years. While many last for years beyond the warranty’s expiration, if you notice inadequacies in your tank’s performance and the tank is beyond its warranty date, it’s probably time to get a new one.
Tankless water heaters also tend to last longer than the tank variety. They can last as long as 20 years, where tank style water heaters have a life of closer to 12 years. The drawback of a tankless water heater is that it can only heat so much water at any given time.

Depending on amount of water used before and age of heater. This depends on age and how many gallons it is heating. If it is new & just filled or you ran out of hot water, About an hour. 3kW electric on a 50 gal tank (US) = 10,236 BtuH on 400 lb water. Since 1 BtuH = 1 lb water/1 degree F/Hr then 10,236 BtuH will heat 400 lb by about 25 deg F. in one hour. If you fill the tank completely with cold water at 40 deg F and want it at 140 deg F, then it will take about 4 Hr. Same tank on natural gas at 50,000 BtuH will take about 45 min.

how much energy an ice absorb
1 The process involves the ice melting to water, the water heating from 0 °C to 100 °C, then the water boiling to steam. The energy absorbed will be the heat of fusion + the change in temperature of the liquid + the heat of vaporization, qfusion + qheating + qvaporization.
The specific enthalpy of fusion of water is 333.55 kJ/kg at 0 °C, i.e. melting ice absorbs the same energy as ice warming from -160 degrees Celsius up to its melting point. Similarly the heat needed to melt ice at 0°C, would heat the same amount of water by about 80°C.

what is a steam oven
Steam ovens boil water from an inbuilt reservoir to create a cloud of steam within the oven chamber. This moist heating method is the reason why steam cooking offers significant benefits.
A steam engine is a machine that burns coal to release the heat energy it contains—so it's an example of what we call a heat engine. It's a bit like a giant kettle sitting on top of a coal fire. The heat from the fire boils the water in the kettle and turns it into steam.

how tankless water heaters work
To accomplish the job, your boiler has a tankless water heater. In this system, a coil of pipe is connected at one end to the cold water supply, and at the other to your hot-water delivery piping. As the boiler heats the water that warms your home, that water heats the coil, creating hot water at your taps.
What They Do. Tankless water heaters provide hot water where you need it -- such as the kitchen sink -- by heating the water quickly when the faucet is turned on. This can save on water costs if you typically have to run water for some time to get it heated.

how water brings pressure down
In contrast, the more water you drink, the more fluid your kidneys excrete as urine, explains physician Julian Whitaker. Because there's less need to conserve water, your small blood vessels open up, and blood pressure goes down.
What happens then is water displacement. The sandy partials that collect on the bottom of the tank displaces the water ever so slightly. This results in hot spots on the bottom of the tank. When this occurs the flames overheat the tank and begin to break down the steel.

how many btus to raise water temp
You will still require 8.34 BTU to raise the temperature of a gallon of water one degree F. 1 I say approximately because the weight of water varies slightly with its temperature. 2 Water is at its densest at 4 degrees Celsius (39 degrees F). 3 A gallon of water at temperatures above and below that value will weigh less.
BTU = British Thermal Unit. A BTU is the amount of energy required to raise one pound of water one degree fahrenheit. On burners it refers to a rating and the number is a calculated value. The manufacturer determines what their rating is. Some burners are rated by the manufacturer to go to 23K BTUs.

You can enhance the efficiency and prolong the life of your water heater by flushing it out. This is especially important if you do not have a water filter on the incoming line of your water supply to your house.
Remove the blockage by flushing the heater core with fresh water from a garden hose. Answer You can flush the heater core by removing the inlet and outlet hose connections and then using a garden hose to back-flush the core.nother more effective method involves flushing the entire cooling system, which is probably a good idea if the core is stopped up. Look for a flush kit that installs into the heater lines (Prestone makes a decent kit). Drain the cooling system, then attach a garden hose to the T installed in the heater line.

why is refrigerator water hot
Water tank/reservoir is inside the fresh food section ( behind the lower crsipers ) and should be the same temp as inside ( water line does come out of the cabinet, runs underneath the refrigerator and up the freezer door to the dispensor so the first little bit of water is always warm(er) than the rest ).
Therefore, you want your refrigerator to be cold, but not so cold that it freezes things. The preferred temperature is somewhere between 35 and 38 degrees F (1.7 to 3.3 degrees C).Anything higher and foods will spoil too quickly (it also presents food poisoning problems, as described in several of the links below).If you have read How Food Preservation Works, then you know that the purpose of a refrigerator is to slow down the growth of bacteria.

how to measure btu on a hot water storage tank
It takes one Btu per pound of water to raise the temperature by one degree Fahrenheit. The standard size of American hot water heaters is 40 gallons, and each gallon of water weighs 8.33 pounds. Calculate the Btu. If you have a 40-gallon water heater, that is 40 multiplied by 8.33, or 333.2 pounds of water. So you need 333.2 Btu to raise the water 1 degree Fahrenheit. However, most areas need more than one degree of heat added to the water to make it warm enough for showering or washing clothes or dishes.
The water heater is rated at 11,000 to 199,000 Btu/hour gas input, has a maximum hot water delivery (at a 45°F temperature rise) of 8.4 gpm, and has a minimum flow rate of 0.26 gpm. There are two primary types of water heaters: storage and tankless.n the case of electric storage tank water heaters the wall loss is less than 10% of total water heater energy use. Conventional gas fired storage water heaters DO have very high standby losses, but that has little to do with tank wall insulation but LOTS to do with convective loss up the central flue.

what causes a water heater to stop working
A heater can stop working for a number of reasons, including: •A low antifreeze/water level in the radiator due to a leak in the cooling system. •A bad thermostat that isn’t allowing the engine to properly warm up. •A blower fan that isn’t working properly.
Like most parts, water heater elements have a finite working life. Continual cycling to satisfy hot water demand eventually wears out the element. Mineral deposits in the water hasten an element’s demise. The heating cycle causes dissolved minerals to solidify. They can coat an element, acting like a jacket of insulative material. In some cases, mineral sediment collects at the bottom of the water heater tank, encasing the lower element. Forced to work harder, the element eventually fails.

what is the boiling temperature of water
The boiling point of water is 100°C, 212°F or 373.15 Kelvin under standard conditions at sea level (at one atmosphere of pressure). The boiling point of water and any other substance depends on the atmospheric pressure, which changes with elevation. At higher altitudes, the pressure is lower, and so water boils at a lower temperature. If the barometric pressure is not at the standard value, the boiling point will be different. For example, water boils at 72 degrees Celsius on Mount Everest. Under a partial vacuum water boils at room temperature.
The boiling point of water is always 100 C (212 F). The differences in the boiling point of water depends on the: altitude, extra ingredients in the water (salt, sugar, alcohol), and water hardness (due to the mineral contents). LdatM · 7 years ago.

This conversion of liquid water to water vapor (steam) is what you see when you're looking at a pot of boiling water. As we all know, for pure water at standard pressure (the air pressure that exists at sea level), the temperature at which this occurs is 212°F (100°C).

Solar Geyser Direct relies on warm water rising, a phenomenon known as natural convection, to circulate water through the flat plate collector and to the tank.
A typical geyser timer installation takes about 20-30 minutes and our installers will test the timer to ensure that you have hot water from your geyser before they leave. With more than 200 successful installations already done and with the Annual Electricity Price increases on their way, there is a solution.aximise your geyser efficiency by adding a geyser blanket. This combination of the geyser timer installation and the geyser blanket has proved itself the most effective way of cutting down the energy use on your geyser.

hot steam temperature
steam condensing rate is known. In the application section of this Handbook, there are several references to the use of the steam table. Total Heat of Steam (Column 6). The sum of the Heat of the Liquid (Column 4) and Latent Heat (Column 5) in Btu. It is the total heat in steam above 32°F. Specific Volume of Liquid (Column 7). The volume per unit of mass in cubic feet per pound. Specific Volume of Steam (Column 8). The volume per unit of mass in cubic feet per pound.
However, if heat is added to the saturated steam (shown. in Image 2), the steam’s temperature rises—and in the case. of this illustration, superheats the temperature of the steam. from 212°F to 232°F. The amount of superheat in a vapor is determined by sub-. tracting the saturation temperature from the actual vapor.

what do you look for to see if your water heater needs to be replaced
You will know when to replace your water heater when you find it has rust and corrosion, it produces cold or luke-warm water, it is older than 10 years, you are constantly finding leaks, or you are not able to drain water through the valve. Look for these signs when determining when your water heater needs to be replaced: Rust and Corrosion: This is the most important factor to identify as the rust will cause the tank to be weak and eventually burst to cause a flood in your home. One of the most common ways to find rust is to see it in your tap water. You can also find it by the pressure relief and temperature valve or the water inlet and outlet connections. If you have not noticed a leak yet, be sure to inspect all around the ...
If water is leaking from hot or cold water lines your water heater should be okay. If the water heater is dry on the top, check the hose bib (place where hose can be hooked up) at the bottom side of water heater. If the hose bib is dry the water heater needs replaced. Before turning water off to a gas water heater.

does water heaters drain thru the pressure valve
Determine whether or not the valve is actually clogged. Turn off the water heater at the breaker panel. Alternatively, turn the gas valve until the valve sits perpendicular along the gas pipe. Attach a drain hose if the drain valve is not within close proximity to a drain. Open the drain valve and begin to drain the tank. Open the pressure-relief valve on top of the water heater. Alternatively, turn on a hot water faucet. This will eliminate the negative pressure in the tank and allow it to drain. If the drain begins to run clean and clear, the problem is solved. If the water still trickles out, the valve is clogged.

can water heater temperature increase electric bill
Increasing your water heater temperature by just 10ºF from 130ºF to 140ºF may increase heat loss resulting in a larger electric bill from $30 to $75 dollars annually. Setting the temperature to 140ºF can also increase demand losses resulting in an annual expense of up to $500 dollars.

The SB800 holds enough power for 3 auto TTL flashes. However final recycling can be 3 seconds once it has used up stored energy after 3 shots. Add the 5th battery with extended compartment or hook up to external power source and fires and recycles faster. Find specifications on Nikon site, or google the specifications of this flash. If you are taking photos at higher iso like 1200 or 1600 iso, it will not use as much flash power.

What is the ratio between muscle and fat among post-pubertal boys?
Another set of significant physical changes during puberty happen in bodily distribution of fat and muscle. This process is different for females and males. Before puberty, there are nearly no sex differences in fat and muscle distribution; during puberty, boys grow muscle much faster than girls, although both sexes experience rapid muscle development. In contrast, though both sexes experience an increase in body fat, the increase is much more significant for girls. Frequently, the increase in fat for girls happens in their years just before puberty. The ratio between muscle and fat among post-pubertal boys is around three to one, while for girls it is about five to four. This may help explain sex differences in athletic performance.
Even though proportionality is confined to the proportional seats to prevent a part from being overrepresented, several restrictions apply in the assignation of the seats; namely, that no party can have more than 63% of all seats, both uninominal and plurinominal. In the 2006 elections leftist PRD got the absolute majority in the direct uninominal elections, securing 34 of the 40 FPP seats. As such, the PRD was not assigned any plurinominal seat to comply with the law that prevents over-representation. The overall composition of the Legislative Assembly is:

how come guys usually have bigger muscles than girls? and why is it so easy for them to gain muscles?
Shortly because male people have more muscular mass and consequentially during the exercise the muscles gain more and quickly

Some women's breasts don't grow until they're much older than the age for "average development"...I was very flat-chested until about 18. Also, weight has something to do with it. If you are very thin, you breasts won't grow b/c you don't have enough body fat, since breasts are fat. As many of us learn as we get older, breasts get larger the more you weigh.

It's from puberty (about 10,11,12 these days-must be the streroids in the meat we eat) through later teens (18,19,20). Then again when she is pregnant. Another time would be during implants.\nAnd usually, it is common for both of them to get bigger at the same time, not just a "chosen" one (as your question suggests)

Is it ok to love someone who is around 20 years older than you? Maybe more maybe less...and well I'm only 14. So if it is what should I do? Should I do anything or just keep my feelings to myself?
wrong,you have so so much more growing to do.
Can I ask why you are worried?\n\nAt 14, your body will store "energy" to grow. This is not to say you should plant on the couch and stuff burgers in your mouth, but do not obsess!\n\nBe active. Dance, aerobics, whatever you enjoy, but don't sweat it. Your body will go through odd spurts to grow. Please don't worry too much about it, but just try to remain healthy.\n\nAFTER your body has reached it growth peak, you need to burn more calories that you intake, to lose weight. If you are truly concerned, see your doctor for advice.\n\nI say this as someone that had to overcome an eating disorder.

my 8 year old is skinny how do i get him to gain weight?
What a coincidence. I was just looking at pictures of my son from age 14, 15,16, 17, 18, and now at 19. He is SOOOOO skinny. I guess I never really noticed. I knew he was thin, I mean he's now 6'4" and weighs 151 pounds. He has not been chubby since he was 3 months old and solely survived on breast milk.\n\nYet he is very healthy, athletic, intelligent and eats like a horse. His sister, who is 16, 5'9", weighs 155 (tell me THAT's not an issue) tells me she knows a lot of skinny guys her age. The doctor tells me he is and always has been healthy, if low weight percentile, and I shouldn't worry.\n\nStill. I worry. Why are we never satisfied? Do you really think you need to worry? B/c if so, get a good diet from your pediatrician, and add pediasure supplements to it. That'll help, at least in the short run. \n\nGood luck.

Okay so i'm 14 and all of my friends are really skinny and most of them have boyfriends, i've had boyfriends before but not as many as most of my friends and i think it's because i'm not really skinny, what do you think, do you prefer really skinny girls or average girls?
This is tuff. Believe it or not, guys like different things in girls. Some guys like girls that are like sticks, some like girls with some meat on there bones. Some guys like small boobs, some guys like big boobs. The most important thing for you to ALWAYS remember it you need to like yourself. If you don't like yourself it is hard for others to like you. Any guy, and I do mean any, should like you for you. Not because you have big boobs and are a stick. They are not really worthy of you if they don't accept you for whom you are. As far as that goes, you need to accept you for whom you are. Don't worry, you are young. In time you will find the right guy. Don't place a large enfasist on trying to be with a guy now. Hard to accept but you should worry about doing well in school. This way when you are older, you will be smarter and make allot of money and then the guys will flock around because you are not poor. Good luck.
The amount of fat you have is totally dependent on what you eat, how much you eat, and how much exercise you get. There really is now such thing as "baby fat". That's just something people have made up to to give false reassurance to their children, "Oh, that's just baby fat and you'll grow out of it.".\n\nI don't know how old you are, but you are never too young to eat a healthy diet with the amount of calories that will keep you from having to much fat on you. You are not too young to take a brisk walk every day and play in appropriate sports for for your age and health level.\n\nGod bless you and I wish you success in every area of your life.

I'm only thirteen but i think im pretty much done growing. im only 4"9... how can i get taller?
I wouldn't consider it a problem. A lot of guys, including myself, find short girls attractive. Enjoy the attention!
there are a lot of ways to increase metabolism.\n\n1. exercise. exercise increases metabolism because like any activity that requires you to move and exert effort, you are expending energy and thus burning calories.\n\n2. muscle gain. exercising with weights will lead to muscle gain which will in turn lead to a higher metabolism. Your metabolism will increase if you gain muscle because those muscles will require extra energy to stay alive and thus the increase in metabolism.\n\n3. eating eating small meals more frequently as opposed to the big 3 (breakfast, lunch, dinner) also increases metabolism. try to eat a small meal every 3 hours. The reason for this is that your body burns more calories since it is constantly digesting something in your stomach and will raise your metabolism.

Everyone has a different build. It really isn't measured by the school grade you are in. The body weight depends on many factors. Such as if you have small, medium or large bones, how tall you are, how muscular you are. I personally try not to even use the scale. If you are feeling a little too thin or too thick, there are many solutions. Ask your school PE teacher to recommend some good weight management books. And start there. But don't try to put a weight limit on yourself just by the grade you are in. Remember every one is different! Be proud of who you are! :)

average weight gain for toddlers
Birth. The average newborn is 19.5 inches long and weighs 7.25 pounds. Boys have a head circumference of about 13.5 inches and girls measure in at 13.3 inches, according to the National Center for Health Statistics.1 Baby Growth Charts: Calculate Height and Weight.2 Charting Baby's Development.irth. The average newborn is 19.5 inches long and weighs 7.25 pounds. Boys have a head circumference of about 13.5 inches and girls measure in at 13.3 inches, according to the National Center for Health Statistics.
According to Robert Malina, an expert on childhood growth, adolescents gain weight and height in a predictable pattern, with height growth occurring first, followed by weight gain, or what I like to call “filling out.”. The average peak height gain in girls occurs between 11 and 13, and in boys between 13 and 15 years of age. The lean tissue (muscles and bones) weight gain during this time is about 15 pounds for girls and twice that for boys (~30 pounds). Girls gain more fat (~6 pounds) on average than boys (~3 pounds) at this time as well. Given these norms for adolescent growth (and the signs that go along with it), you can begin to see that an important transformation happens in teens, and much of it is to be expected.
