It depends on a lot of factors, however, a 1500 watt heater should draw 12.5 amps at 120v. If you want to use it for 6 hours, a minimum would be 75.
However that being said, batteries work non linearly, so you need to take into account the scale on which the battery is being measured. It's like a car. your best horsepower is what they use for their rating, however, that's the peak performance of the vehicle at a set number of RPM's, and will make the mpg suffer.
Another factor you may want to consider is that most 120v things which are designed to operate in a home with a 120v receptacle, operate on AC and a battery operates on DC.

How much amperage do headlights draw?
Depends on the wattage of the bulb. Formula is Power (watts) = Voltage * Current (A). Therefore for a 55w bulb, in a 12V car, bulb draws 4.6Amps.
Why do we use thicker wires for heaters than for lamps?
Heaters draw a lot more amperage. As your amperage increases, so does resistance to the flow of the current. Too much resistance, and your wire overheats, melts the casing, and can potentially catch fire.
How much does it cost to operate a 1500 watt heater for one hour at 9.1 cents a kwh?
a 1500 w heater consumes 1.5 kW, and used for 1 hour it uses 1.5 kWh of energy, which costs 1.5 x 9.1 cents, that is 13.65 cents.
How much per day will a 1500 watt heater cost you to run if im charged 111748 kwh?
What it costs me to run a heater does not depend on how much you are charged, but a 1500 watt heater would use 1500 watt-hours or 1.5 kWh for every hour it is run. Run for 24 hours it would use 36 kWh, also known as 36 units.
You were given aload 2500 watts how much it draw amps?
To calculate the amperage draw, you need to know the voltage of the circuit where the 2500 watts appliance will be used. You can use the formula: Amps = Watts / Volts. For example, if it is a 120V circuit, the amperage draw would be 2500 watts / 120 volts = 20.83 amps.

You need to mention the voltage and wattage of the device to get the right answer
Why does the heater blower switch get hot?
As heater motors age, they tend to draw more amps than they should. Yours is probably drawing too much amperage causing the switch to heat up. Remedy is to replace the heater motor and possibly the switch as the terminals get hot and oxidize.

4.12A. V=IR
Why does the lower three heater speeds on a 1999 Malibu not work?
The blower motor resistor is defective. They go bad when the blower motor pulls to much amperage.
