A standard draw for residential coil heaters is 1,500 watts. Divide the power specified on the label by its operating voltage to obtain the maximum current draw. If you can plug the heater into a regular wall outlet, the specified voltage should be 120 volts. Thus, the current draw for a 1,500-watt heater is **12.5 amps**.

## How many amps does a 1500 watt electric heater use?

A 1500 watt space heater (on high setting) will draw 12.5 Amps. When a few lights or a television are on the same circuit, the 15 Amp limit is quickly reached and the breaker will trip.

## How many amps does a 1000 watt heater use?

I = 1000 Watts/120 Volt = 8.33 Amps We see that a 1000 W device draws twice as many Amps as a 500 W device.

## How many watts does a 1500 watt heater draw?

The 120-volt, 1,500-watt heater offers an easy way to heat a small space. It generates 1,500 watts of electricity per hour and produce 5,100 BTUs of heat. When sizing an electric heater, a rule of thumb suggests the unit needs to consume 10 watts of power per square foot of room area being heated.

## What size breaker do I need for a 1500 watt heater?

A 1500-watt heater on a 120-volt circuit thus needs a breaker of 15.6 amps. Because a 15-amp breaker would be too small, you need a breaker with the next highest rating, which is 20 amps. Include the current draw of any other devices on the circuit when calculating the breaker size.

## Does a 1500w heater need its own circuit?

Space heaters If you find your space heater isn’t running very long before you’re running out to your breaker panel, the likely culprit is an overloaded circuit. You’ll definitely need a dedicated circuit to handle the 1,500 watts necessary to ensure the safe operation of most space heater models.

## What size breaker do I need for a 1000 watt heater?

Since this is a 240 volt heater that produces 1000 watts, the amperage will be equal to 1000 watts divided by 240 volts or 4.167 amps. Since you want the breaker to operate at (say) 80% of peak capacity, the breaker’s rating should be 4.167 amps divided by.

## Does a 1500 watt heater use much power?

Most electric heaters use 1,500 watts, but some are slightly less or slightly more. Since 1,000 watts equals 1 kilowatt, that means your heater uses 1.5 kilowatts of power. However, your electric bill is measured in kilowatt hours, which is the amount of energy used while running a 1-kilowatt appliance for one hour.

## How much does it cost to run a 1500 watt heater for 8 hours?

On average, a 1,500W heater costs around $0.20 per hour to run on high. This adds up to a cost of $1.60 for 8 hours a day, and $48 per month.

## How many watts is 40 amps?

40-amp 240-volt circuit: 40 amps x 240 volts = 9,600 watts.

## How many watts is A 100 amps?

240 volts x 100 amps = 24,000 watts.

## How many watts is 2.4 amps?

The higher power (2.4amps or 2.4A, 12watts or 12W) chargers are often required by modern phones and tablets in order to charge the device. Lesser powered USB chargers (1A or 5W) have been the standard for many years but they are only sufficient for charging smaller mobile devices.
