What will happen if the heating element is near at the top of the kettle?
In that case, it would be less efficient. Hot water rises to the top, mixing the water (if the heating element is at the bottom). When it is at the top, the water won't mix as well, and more heat would be wasted.
Why is your hot water all of a sudden very hot?
If water heater is electric, usually bottom element is going bad. Replace ASAP.
Where does the air flow into an electric heater?
From the bottom, unless there's a fan ... in which case it flows in from behind the fan.
How does a convector heater work?
Inside an electric convector heater there is a large heating element similar to - but bigger than - one of the elements inside a bread toaster.When the electricity is switched on the element gets hot and heats up the air that is all around it.Because hot air is lighter than cold air, the hot air rises up and comes out, into the room, through the grilles at the top of the heater. Cold air from the room moves in through the grilles at the bottom of the heater to take the place of the hot air, and this process continues for as long as the heater is switched on.Any movement of air in that way - cold air taking the place of hot air moving up - is called "convection", which is why the appliance is called a convection heater.Electric fan heaters work in a different way: they have a powerful electric fan inside, which sucks in cold air from the room. The fan then blows the air through an electrically heated element and that hot air then comes out of the fan heater into the room.
How do you calculate neutrons for elements in the periodic table?
them mass number of an element is the total amount of nuetrons and protons in the element , and the atomic number is the amount of protons ( and electrons) in the element simply subtract the atomic number from the mass number and you'll have the number of neutrons in the element hope this helped x
Where are electric immersion heaters positioned in a hot water tank?
There should be two heating elements, one towards the top and one at the bottom. Front side with a cover plate over them.
How does car seat heating work?
Car seat heating works by using electrical heating elements. They are positioned in the bottom and back of the seat and receive power directly from the vehicle.
Why is the element at the bottom in a electric kettle?
It is not an element... for hard water usually a build up calcium compounds.
Where is the heating element on a maytag Neptune dryer?
The heating element is on the bottom in the back, if you pull the front base panel off, you can look back and see the element against the back of the dryer. You can undo two screws and pull the element out. "MAKE SURE TO UNPLUG THE DRYER FIRST SO YOU DO NOT GET SHOCKED" Jeremy
How does a hot water heater work?
answer 2 Assume an electric hot water cylinder. The cold water is introduced at the bottom of the cylinder, for upon heating, the hot water will rise to the top. If you put cold water in at the top, this would cool the hot water you had just paid for! The hot water will be taken from the top, for that is where it will be.In an electric cylinder, there will be an electric heating element about 150 mm from the bottom of the cylinder.[There will always be dirt and crud in the water supply, and some of this will settle at the bottom of the cylinder. Having the element above this will avoid the crud being disturbed each time the element is turned on.]In the electrical circuit to the heating element, there will be a thermostat, to set the highest temperature to which the water will go. This is vital for safety, as water too hot can cause scolding.In addition, the electrical supply authority may only allow you to heat your hot water for certain hours of the day, hours when the demand otherwise is least.A cylindrical shape is chosen, for engineering strength. This will be thermally insulated, otherwise you will lose too much heat.

When you put 3 cookie sheets in an oven why doesn't the bottom sheet burn?
The bottom sheet does not burn because one would be careful not to position the bottom rack too close to the heating element.
What is a heating mantle and how do you use it?
A heating mantle is the best way to heat a liquid in a round bottom flask. The heating mantle can be either rigid or soft, but heats the flask by heating an electric coil which surrounds the round bottom flask. Heating mantles come in different sizes to best match the size of the found bottom flask for a snug fit around the entire bottom of the flask. They are commonly used in distillations and other heated reactions.A heating mantle if much better than a hot plate because the heating mantle makes contact with the entire bottom surface of a round bottom flask. It is also much better than a Bunsen burner for heating flammable liquids.See the Related Questions and Web Links to the left for more information.
Is an electrical rice cooker an appliances that makes use of electrical heating?
Yes, there is a small electrical element in the bottom of the unit that heats up the water to cook the rice. Look for a nameplate on the bottom or on the side. There is should tell you what the wattage of the element is.
Electric water heater you have a electric water heater that for some reason keeps failing to heat water It has a new element thermostat and breaker what else could it be?
Try checking the heating element itself. Do this by removing it and using an ohm meter to check it for an "open" circuit condition. If the ohm meter reads infinite, then it is likely bad. If the water heater is only slow to heat, a very likely possibility is that you have an excess amount of sediment in the bottom of the tank, insulating the heating element from the water. Back flushing the tank will solve this problem. For more tips, check out the following web site: www.waterheaterrescue.com
Why would condensation build up in an electric water heater and trip the breaker in a garage in Florida and you shut off the water heater frequently because it's a 2nd home?
If your having condensation at the bottom of the unit it could be that the bottom element has gone bad and when the cold water comes in and hits the warm tank it is condensating. Also if heating element has gone bad that could be a definite cause for the breaker to keep tripping.
Why are heating elements of toasters made of alloy instead of iron?
1). You want the resistance of the heating element to be somewhat more than the resistance of a pure iron one. 2). When the heating element heats up to glowing, you don't want it to melt and fall to the bottom of the toaster in a blob. So you need a substance with a melting temperature higher than that of pure iron.
