== == There is not enough information given to properly answer this question. We need to know the voltage for the heater. We can then apply ohm's law to find the amperage to find wire size. If the circuit is 120 volts then 1500 watts / 120 volts = 12.5 amps. The National Electric Code requires elecric heating circuits to be considered a continuous load so you must increase the required circuit by 25%. In other words 12.5 amps x 125% =15.625 amps. This would require a 20 amp / 120 volt circuit using #12 copper wire. If the heater requires 240 volts the formula for calculation is the same with a circuit requirement of 15 amps / 240 volts using #14 copper conductor.

A standard 15 amp 2 pole circuit breaker using a feeder of #14 AWG will work fine in this scenario. Amps = Watts/Volts = 1500/230 = 6.5 amps.In a home setting up to two 1500 watt heater can be installed on a two pole 15 amp breaker.

use 20 amp single pole and 10 gauge wire that will give you 2200 watts that will be good

Depends on your supply voltage. I = P/V. Find out your supply voltage and divide it into 1500. This will give you your heater's current draw in amps.

You need 12.5 Amps. For a continuous load you want to only have 80% of the current which would be 12 Amps. Best to go with a 20 Amp breaker.

That is a load of 6½ amps. You should use at least 1 mm2 cable and preferably 1.5 mm2 which is the standard cable for a spur with a 13 amps fuse.

AWG 12/2 with ground on a dedicated circuit with a 20 amp breaker. That will safely supply 1920 watts of continuous power.

What size breaker for a 1500 watt 120 volt heater?

To calculate the breaker size for a 1500-watt 120-volt heater, use the formula: Breaker size = Power (Watts) / Volts. In this case, 1500 watts / 120 volts = 12.5 amps. Therefore, you would need a 15-amp breaker for a 1500-watt 120-volt heater to allow for a safety margin.


What is the length of a 1500 watt baseboard heater?

The length of a 1500 watt baseboard heater can vary depending on the model and manufacturer. Typically, a 1500 watt baseboard heater can range from around 48 to 72 inches in length. It's best to check the specifications provided by the manufacturer for the specific heater you are interested in.


What size fuse for a 1500 watt block heater?

For a 1500 watt block heater, you would typically use a 15 amp fuse. This is calculated by dividing the watts (1500) by the voltage (120 in most cases) to get the amperage. In this case, 1500 watts / 120 volts = 12.5 amps, so a 15 amp fuse would be the appropriate size to accommodate any potential spikes in power usage.


Are all 1500 watt heaters equal in btu?

No, not all 1500 watt heaters are equal in BTU. The BTU output of a heater is dependent on factors like the efficiency of the heating element and design of the heater. While a 1500 watt heater will generate around 5118 BTUs, variations in design can lead to differences in heating performance.


What are the BTUs for the Lasko Electric Ceramic 1500 watt Tower Heater with remote control number 751320?

1500 watts is equivalent to 5118 BTU per hour. 1500 watt-hours is equivalent to 5118 BTU.

By radiation.


Can you run one 1500 watt heater on a 125V- 15A 60Hz power strip?

Yes, a 1500 watt heater operating on 120 volts has an amperage of A = W/V. Amps = Watts/Volts = 1500/120 = 12.5 amps. It is not a recommended practice to do so.

Cost of 1500 watt block heater?

Usually much smaller. A normal freeze plug block heater is about fifty bucks.


Can you plug a 1500 watt heater in to a regular apartment outlet?

No, a 1500 watt heater exceeds the typical 120 volt, 15 amp capacity of a regular apartment outlet. It requires a dedicated circuit with a higher amp capacity to safely operate the heater without overloading the circuit and causing a fire hazard.


How many watts does a small ceramic heater use?

A small ceramic heater typically uses between 750 to 1500 watts of power. It's important to note the specific wattage of the heater since it may vary depending on the model and size.
