One can practice both safety and economy by keeping water temperature at doctor approved levels. Very hot water temperature can cause burns with great rapidity, and as such, care in setting your hot water heater is required. Setting the hot water temperature lower also means a savings in energy bills for heating the home's water in many cases. However, a lower temperature does mean you will run out of hot water more quickly.Most experts recommend that hot water temperature should not exceed 125° F (51.66° C). A water temperature exceeding this poses serious risk of bad burns, particularly to children. In fact even at 125° F, if the child puts his or her hand in the water continuously for two minutes he or she may get second or third degree burns.Some pediatricians instead suggest setting the hot water temperature at 120° F (48.88° C). With this water temperature, a child would have to run water over the same place for ten minutes prior to receiving a severe burn.Temperatures higher than 125° F can burn a child, or an adult quite severely, and quite quickly.
De watertemperatuurgegevens zijn 10-minuutgemiddelden van de gemeten temperatuur, uitgedrukt in graden Celsius. Bij sommige meetlocaties op de kaart staat de diepte van het meetinstrument aangegeven. Bijvoorbeeld 'Krimpen IJssel NAP -4.0m'. Dit betekent dat het meetinstrument 4 meter onder NAP is opgesteld. Meer informatie. Water Temperature Table of the Southern Pacific Coast IMPORTANT NOTICES: The table below shows the near real-time and average water temperatures in degrees Fahrenheit (°F).
For example, it is estimated that it takes only two seconds of exposure to water at 150° F (65.55° C) and only six seconds of exposure to water at 140° F (60° C) to cause a very bad burn to a child. Some are concerned that lowering the water temperature will result in soap working improperly in dishwashers or washing machines. Actually most soap and detergent is meant to work at between 120° to 125° F.
Thus soap is actually designed for this temperature.Others are concerned that lowering water temperature might lead to greater chances of passing illness between family members. Actually, the best method for preventing illnesses is handwashing with warm, not hot, soapy water.
120° F water is quite hot enough to wash most germs away. It will not always work, since some germs are airborne and one contracts them through exposure or inhalation of the infected droplets of someone else, as after a sneeze.In terms of cost saving, dropping the water temperature setting by ten degrees typically saves approximately 4% on one’s cost to heat water each year. This can make a profound difference if dropping the water temperature from 150° to 120° F, saving essentially 12% a year. Every water heater is preset in America to 120F by the manufactures, but some states like Wisconsin require the water heater temp to be at least 125F. I set mine at 125F, which is the recommended setting for my REEM water heater. It all depends though, on the size of your water heater and the number of machines using your water heater, as well.
I find setting it below 115F is way too low, because by the time the water reaches my shower on the other side of the house, it's already cooled off a good 10 or more degrees. And if the dishwasher or washing machine are running, it cools the water temp even more to the point where. I think the hot water temperature problem at a large institution is more of a heat recovery situation than a thermostat setting problem. If I only have a hot water tank that holds 200 gallons, for example, there's every chance the fifth or sixth bather is going to get nothing but cold water. The tank hasn't had time to heat the incoming water, and it wouldn't matter if I set the thermostat to 120 degrees or an insane 200 degrees- there's only a finite amount of water that a traditional hot water tank can process.My suggestion for hotels with numerous guest rooms and a limited hot water supply would be to install individual hot-water-on-demand units in.
It might be a significant investment up front, and maintenance on those kind of units can be more expensive than traditional hot water tanks, but at least customer no. 7 won't have to suffer because customers one through six beat him or her to the shower in the morning.It may not be the best solution for a private home (just invest in a larger traditional tank), but in a situation where customer satisfaction is a high priority, modern heat-on-demand units set at a child-safe temperature could prevent further problems with room refunds and angry phone calls to the front desk. #7 5 and 3 are missing the point. You can shower with anti-bacterial soap. But what about the walls and tub bottom? Are they sanitized before you enter to shower? Same with the bathroom floor and everything else in your home and all homes, so don't feel i disrespected either of you.

It was not my intention.i was in the appliance repair business for 40 years as a technician and then owner tech. Legionnaires was caused by bacteria in the drain line from a combination of dust water which creates a slime very much like snot.
Pull out the drip tray under your refrigerator and you will see brown stains, maybe water, and sometimes a greenish. This occurs because when your fridge defrosts the water goes down a tube to the drip tray which is then evaporated by the condenser fan, which has dust all over it and sits right next to the condenser coils which removes heat from the refrigerant which draws the heat from the evaporator coil in your freezer. This is the basics of how a refrigerator works.to sum it up, you have a warm condenser coil trying to be cooled by a condenser fan which blows air through your dirty condenser into your kitchen. That's why you feel warmth on you feet, also why your dog and cat love to lie in front of it in the winter. This adds dander to the drip tray to boot.
You have the perfect formula for air borne legionnaires disease.i always tell mothers of toddlers to clean the drip pan at least once a month to prevent diseases from affecting their babies, or at least cut down a dangerous situation. So carry water with you so you needn't use a water fountain, and whatever germs are out there at least you restricted one.

Unless you go visiting and sit in the kitchen. Every person that dies (excepting drive bys and tragedy) dies from (help me with this) pneumonia because the weakened body cannot fight that germ. It's true, all of it is true.
Okay, how'd i do #7? #4 if you let 170 degree water hit a metal pan for a few minutes you could fry an egg.
Set the water 120-130 and add cold water as needed. If you have hard water and your dishwasher leaves spots push the button for high temp. Wash and it will do the trick. 140 and above settings are a waste of oil to me.our heater comes on 30-45 seconds after we turn on hot water and shuts off seconds after we shut water off.
Someone shut the heater off and nobody noticed for almost three days. We had a electric heater (also known as the silent thief) which wasn't bad when energy was cheap. My wonderful plumber advises we set the hot water tank to 130 degrees.
He says that there is always a dip in temperature before the tank thermostat calls for more heating, and if you set at 120 degrees, your tank is cycling below 120, and you risk having bacteria colonize the tanks. Legionella is the big concern here, and note that babies, the elderly, and the immunocompromised (chronically ill, cancer patients) are more vulnerable to Legionella than the rest of us.
If you are concerned about energy costs, you can go to a smaller but more efficient tank system. But don't drop the temp to save money. Too many people seem to be thinking that the ideal water temperature is what you measure as it comes out of the tap before any mixing with cold water. This is wrong.Hot water is meant to be stored at a high enough temperature to kill off legionella (70C or slightly higher). Mixing this hot water with cold (ideally through a thermostatic tap will produce the ideal temperature for a shower or bath, without risk of scalding (set to your choice) and without risk of catching legionnaires disease when taking a shower (most common way - breathing in water vapour / droplets). It need not cost more to store water at this higher temperature, you just need extra tank insulation to the.
The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress.For further definitions, go to. Absolute or dynamic viscosity is used to calculate to determine if a fluid flow is laminar, transient or turbulent.Online Water Viscosity CalculatorThe calculator below can be used to calculate the liquid water dynamic or kinematic viscosity at given temperatures.The output dynamic viscosity is given as cP, mPa.s, Pa.s, N.s/m 2,lb f.s/ft 2 and lb m/(ft.h),while the kinematic viscosity is given as cSt, m 2/s, and ft 2/sNote! Temperature must be within the ranges 0-370 °C, 32-700 °F, 273-645 K and 492-1160 °R to get valid values.Temperature Choose the actual unit of temperature:°C °F K °RSee and - thermodynamic properties.See also other properties of Water at varying temperature and pressure:, and.See also dynamic and kinematic viscosity of, and.The figures and tables below shows how water viscosity changes with temperature (°C and °F) at water saturation pressure (which for practicle use, gives the same result as atmospheric pressure at temperatures.
