1150 watt, 10A
I ASSUME the block heater in a 2006 Ford Freestar would use ( 600 watts ) like my Ford Explorer 4.0 liter V6 engine does
Check the wattage used by the block heater which should be listed on the heater. If it is 2000 watts or less then the generator will run it.
1300/1500 watts
To answer this question the wattage of the block heater must be stated. Amps = Watts/Volts.
It uses 1150 watts, or 10 amps.
I was looking at one of the Ford websites and the drawing shows two engine block heaters ( each one is rated at 1000 watts ) They are located on the passenger side of the engine block , in the front and middle expansion plug ( frost plug ) holes on the 7.3 liter diesel in a 1990 Ford F-250 * the drawing also shows that the heating elements are positioned facing UP
1000 watts
Find the block heater and look for the nameplate on it. It will be in watts. Use the following equation to find the amperage that it draws. Amps = Watts/Volts. The voltage to use for the truck will be 12 volts.
Ford OEM block heaters are all 600watt (5.3 amp x 115 volt). aftermarket heaters are available up to 1000watt. (1 kilowatt).
Watts is the amount of power the heater has and amps would be the draw- if it is a 120 volt heater than the amps would be 12.5 amps and it is instantaneous
A ceramic heater uses the same amount as a regular heater. Most heater use 1500 watts so in one hour a 1500 watt home heater will use 12.5 amp hours.
for a large one it is 4,000 watts and for a smaller one it is 1,000 watts
