Check the appliance's specifications on the strip, tag or plate that is usually fixed either on the back or somewhere on the frame. On there you will find its required operating voltage and wattage that it draws.
If your home has 240 volt line voltage just divide the watts by the volts for the answer.
Example: a 2400 watt water heater for a 240 volt line using the formula watts / volts = amps would give you 10 amps. For a 120 volt appliance it would be 20 amps.

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
How do you check to see which element is bad in a hot water heater with an ohms meter?
To test and replace a heating element: # Turn off power at the Electrical Service Panel and post a sign warning others not to turn it on. # Remove the access panel on the electric water heater. # Disconnect one of the element wires and set a multimeter to RX1000 (resistance times 1,000). Touch one probe to an element mounting bolt and the other to each element terminal screw, in turn. If the tester displays anything but infinity (open circuit), replace the element. # If necessary, set the multimeter to RX1 and touch the probes to the terminal screws. If there is any resistance reading at all (closed circuit), then the element is good. If not, replace it. Both upper and lower elements are tested in the same manner. # To remove the element, first drain the heater. # Disconnect the remaining element wire. Remove the mounting bolts holding the element in place. Remove the element. # Replace the heating element with one of the same model, shape, and rating. Make sure you also replace any installation gaskets.
Can I use 240 volt heater elements in a 120 volt hot water heater?
No. For an example using a 3500 watt element. The amperage through the element will be I = W/E, 3500/120 = 29 amps. The resistance of this 3500 watt element will be R = E/I, 120/29 = 4.13 ohms. Now using the 200 volts and finding the amperage I = E/R, 200/4.13 = 48 amps. The new wattage of the element has become W = A x V, 48 x 200 = 9600 watts. The element will not stand the increase in amperage and will burn open. To operate on 200 volts and still have a 3500 element in the tank you will have to find an element with a resistance of 12 ohms. I = W/E, 3500/200 = 17 amps. R = E/I = 200/17 = 12 ohms. This is a resistance three times more than the 120 volt element to achieve the 3500 watt rating.
Ways you turn natural gas into enery you can use?
Burn it to produce electicity, or burn it in a water heater for central heating, or burn it in a stove or open fire in a home
When checking an electric heating element you read voltage but no amperage What can you determine about the heating element?
the element has a open in it !
2002 transit wont start heater plug light flashing?
Piston heater element open.
What does it mean when it says heater circuit is high?
The circuit is open. Wires could be disconnected/damaged or the heater element is burned out.
What causes a block heater open circuit?
The heating element probably burned out causing the open circuit. The element needs to be submerged in coolant completely, all the time that it is plugged in.

How do you know if your hot water heater valve is open?
You know it by touching and feeling the pipes on the hot water side; if they are hot, there is water running through the pipes and obviously the heater valve is open on hot side.
You Have 94 Caprice Classic Da Heat Won't get hot It will get a lil warm but that it's you Put a heater element in it so what's da problem?
By heater element I am assuming you mean a heater core. If that is the case then you have one of two problems. Either the thermostat is stuck open and needs replacing or the heater temperature control valve is defective.
Can you fill a children's pool using a hot water heater?
Yes! Connect a garden hose to the output valve of the water heater and open the water heater valve to put hot water into the kiddie pool. This is the fastest way to warm a children's pool.
How to Keep Your Water Heater Clean?
By Andreina Urdaneta A clean water heater will heat and maintain water better and last longer. Once a year, flush your water heater, and in extreme hard water areas, at least twice a year. If you feel up to the challenge, here are some tips to help you in a basic cleaning. 1 Turn the water heater and the cold water supply to the water heater off. 2 Hook a high-quality garden hose to the drain valve, and place the other end in an area where hot water will not cause damage. 5. Open the drain valve. 6. Disconnect the cold water pipe on the top of the water heater. This step will let air into the water heater so it will drain. When the water heater is empty, close the drain. 8. Pour tile cleaner into the cold water, leave for a couple of hours and drain the detergent out of the tank. 10. Reconnect the cold water supply to the water heater. Open the cold water valve and let the water heater flush for a couple minutes. 12. Close the drain valve and open the hot water faucet nearest to the tank, and let the water heater fill. 13. When water starts to come out of that faucet, reopen the drain and let the water heater continue to rinse. After all the air is out of the water heater, turn it back on. Take care of your water heater, and it will take care of you. If you keep ignoring the task, your water heater may just leave you in the cold.
Why wont the seat heaters stay on in 2005 Chevy silverado?
you need to check the resistance of the seat heater elment. each seat has an upper and lower element. your probably going to find an open heater element ckt. gm master tech
If you open hot water valve on the hot water heater what would happen?
The hot water valve should always be open, so the hot water can exit the heater into the system. If your actually meaning opening the drain valve on the bottom of theater, the water in the heater will drain, starting with the hot water stored there, and then the cold water that is entering the tank to replace it will simplt flow out the bottom before being heated. Dpending on where the heater is located will denepnd on how much of a mess the ensuing flood will be.
Will the water drain out of an electric water heater if no water is going in?
yes, but you have to open the relief valve or one of the water connections to allow air to enter the water heater otherwise it will become air-locked and not drain very well.
Can you clean or repair your hot water heater that is leaking from the bottom?
No. Once a water heater tank leaks there is no fixing it. Just replacing the water heater. And it should probably done as soon as possible, since the potential for a bigger leak to open is very possible.
