It uses 1150 watts, or 10 amps.
1300/1500 watts
To answer this question the wattage of the block heater must be stated. Amps = Watts/Volts.
I ASSUME the block heater in a 2006 Ford Freestar would use ( 600 watts ) like my Ford Explorer 4.0 liter V6 engine does
1150 watt, 10A
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.
for a large one it is 4,000 watts and for a smaller one it is 1,000 watts
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.
First you need to find out how many amps the heater draws. Then use this formula: Volts (220) X Amps = Watts Then take: Watts x 3.41214 = Btu/hr
The conversion factor of 1 BTU = 0.293 watts. So, 60,000 * 0.293 watts = 17,580 watts. 17580 watts are required to run a craftsman 60,000 btu propane forced air heater.
Ford OEM block heaters are all 600watt (5.3 amp x 115 volt). aftermarket heaters are available up to 1000watt. (1 kilowatt).
The answer is simple. The block heater is probably in the 500 - 800 watt range. If it came on new car, your dealer should be able to tell you what wattage it is. KAT'S is known brand and can be purchace at http://www.partsamerica.com/BrandCategories.aspx?MfrCode=FIV stores The 15 amp curcuit you are plugging block heater into has nothing to do with the wattage of the heater. It is only a curcuit breaker that trips if more the 1800 watt is applied to it.
To answer this question the voltage of the immersion heater is needed. I = W/E.
