Space heaters are a popular way to heat small spaces or supplement your central heating system. They are moderately cheap, simple to use, and come in various designs. But, if a space heater is not used correctly, it may create a risk of fire. To prevent electric circuits from being overloaded and triggering fires, understanding the number of amps used by a space heater is crucial.

**How Many Amps Does a Space Heater Use?**

Depending on the wattage of the space heater, it may use a certain amount of current. The 12.5 amp current can be generated by the typical 1,500-watt space heater. You will **draw around 16.6 amps** of current with a 2,000-watt space heater.

However, most household electrical circuits must be rated up to a maximum of 15 Amps. This means that you should not operate more than two 1,500-watt space heaters on the same circuit. If you need to operate more than two space heaters, you should plug them into different circuits.

Here is a table showing the approximate amperage draw of different wattage space heaters:

Watts | Voltage | Amps |

500 watt | 120 | 4.16 |

1000 watt | 120 | 8.33 |

1500 watt | 240 | 12.5 |

2000 watt | 240 | 8.33 |

2500 watt | 240 | 10.41 |

3000 watt | 240 | 12.5 |

**How Many Watts Does a Space Heater Use?**

We hope you now have a good understanding of how many amps a space heater uses. Now, let us see how many watts a space heater uses. The number of watts that a space heater uses depends on the model and the manufacturer’s specifications. But, generally, **1,000 and 2,000 watts** are used to heat the majority of space heaters. For example, a typical 1,500-watt space heater will use 1.5 kilowatts of electricity per hour.

It is important to note that the wattage of a space heater is not the same as the amount of heat it produces. Several factors, including the type of heating equipment, room size, and wall insulation are responsible for determining how much heat is generated by a space heater.

**How Many Amps Does a Space Heater Use on Low Power?**

To choose the right space heater for your needs, you should consider the size of the room you need to heat, the amount of heat you need, and the energy efficiency of the heater. It is important to note that the **amperage draw of a space heater can vary depending on the temperature setting**. The higher the temperature setting, the more amps the space heater will use.

The number of amps a space heater uses on low power depends on the model and the manufacturer’s specifications. The majority of space heaters will use more than 10 amps. A typical 1,500-watt space heater will use about **8.3 amps on low**.

**How Many Amps Does a 750-Watt Heater Draw?**

The space heater draws about** 6 amps** of current when running at maximum heat and around 3 amps at an eco or mid-level setting (if your space heater uses one). A 750-watt heater draws 6.25 amps of current. This is calculated using the following formula:

Amps = Watts / Volts |

So, to calculate the amps drawn by a 750-watt heater and assuming a standard voltage of 120 volts for most household appliances in the United States, we would do the following:

Amps = 750 watts / 120 volts = 6.25 amps |

**How Many Amps Does an Electric Water Heater Use?**

The electrical water heater normally has a standard output of **18.8 Amps** with 240 volts and 4500 watts. For every homeowner, knowing the amount of amps needed for water heaters is essential information. It can be a difficult decision to choose a water heater with all the options at your disposal. However, a lot of factors determine the exact amount of electricity an electric heater uses. They are

- Energy efficiency
- Capacity
- Heater type
- Fuel type

However, it takes around 120 Amps to run an on-demand heater which is far more powerful than a conventional unit that only requires 30 Amps for operation.

Space heaters can be a great way to stay warm and comfortable in the winter, but it is important to use them safely. To avoid overloading circuits and causing a fire, always check the amperage rating of a space heater before using it, and do not operate more than two 1,500-watt space heaters on the same circuit.
