Did You Know?

1. Did you know that the average American household needs a generator with a capacity of at least 15 kilowatts (kW) to power electric heat?
2. On average, a 1,500-square-foot home in the United States requires a generator with a capacity of around 20 kW to effectively run an electric heating system.
3. Electric heat systems typically consume more energy than other heating methods, such as gas or oil, making it essential to choose an appropriately sized generator to meet the increased power demand.
4. In colder climates where heating demands are higher, it’s not uncommon for households to require a generator with a capacity of 25-30 kW or even more to run their electric heat systems efficiently.
5. If you have additional power-consuming equipment, such as electric water heaters or space heaters, it’s crucial to factor in their power requirements when determining the appropriate generator size for running electric heat.

Factors Affecting Generator Size For Electric Heat

Running an electric heater requires a generator that can provide adequate power to meet the heating needs of the space. The size of the generator needed can vary depending on several factors. These factors include the square footage of the area to be heated and the wattage requirements of the space heater.

Space heater coverage capabilities range from 25 to 400 square feet, with wattage needs ranging from 250 to 4000 watts. It is important to consider the size of the space when choosing a generator. For example, a 2000 watt generator is sufficient to run a space heater for a 200 square foot area. On the other hand, a 1000 watt generator can easily provide power for a space heater in a 100 square foot area.

Another factor to consider is the specific type of space heater being used. Different types of space heaters have different wattage needs. For example, infrared heaters typically have a low wattage of around 1500 watts and can run well with an inverter generator. Fan heaters, on the other hand, usually have a high wattage of around 2000 watts and can also run well with an inverter generator. Oil-filled radiators have a high wattage of around 2500 watts and may require a portable generator to power them. Ceramic heaters usually have a low wattage of around 1500 watts and can run efficiently with an inverter generator.

Safety Tips For Using Generators With Electric Heat

When using a generator to power electric heat, it is crucial to prioritize safety. Here are some important safety tips to follow:

  • Place the generator outdoors and away from open windows, vents, or doors. This is to prevent carbon monoxide buildup indoors, which can be extremely dangerous.

  • Maintain a safe distance from the generator while it is running. Generators produce heat and can cause burns if touched.

  • Never run the generator while sleeping or leave it unattended. It is important to monitor the generator to ensure its proper functioning and to address any issues in a timely manner.

  • Be prepared to shut off power at the main breaker if the generator starts to smoke, spark, or emit a smell of fire. This is a precautionary measure to minimize the risk of fire or other hazards.

  • Store fuel tanks outdoors to prevent leaks or spills. It is important to handle fuel safely to avoid any accidents or contamination.

Following these safety tips will help ensure a safe and efficient use of generators to power electric heat.
