1300/1500 watts
A typical block heater for a car engine would be around 400-1500 watts, depending on the size and efficiency of the heater. This kind of heater is used to keep the engine warm in cold weather for easier start-ups.
I ASSUME the block heater in a 2006 Ford Freestar would use ( 600 watts ) like my Ford Explorer 4.0 liter V6 engine does
It uses 1150 watts, or 10 amps.
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.
To answer this question the wattage of the block heater must be stated. Amps = Watts/Volts.
The engine Tanis heaters typically consume around 300-700 watts of power, depending on the size and model of the heater.
If the engine is out it's easy. Unfortunately they put so many pieces below the block heater of that model it's almost impossible to change with engine in car.
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.
for a large one it is 4,000 watts and for a smaller one it is 1,000 watts
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
For a 1000 BTU heater, the power consumption would be approximately 293 watts. This is because 1 watt is equivalent to 3.41 BTUs.
