Choosing A Safe Usage

The quantity of electricity they use is a key component in determining how many space heaters you can safely use. Space heaters take a lot of electricity despite their modest size, frequently equaling that of bigger household appliances like refrigerators.

A typical space heater uses about 1,500 watts of power, which is equal to 12.5 amps. The majority of household circuits have a 15 amp rating, which leaves little room for extra appliances. In light of this, if you have a space heater hooked into a circuit, it should be the only thing using the electricity.

To determine which outlets are connected to particular circuits, it is imperative to inspect your breaker box. By being aware of this information, you can use many space heaters without overloading the circuits.

Can Two Space Heaters Be Plugged Into One Outlet?

While it could be alluring to connect several space heaters to a single outlet, it’s important to take your electrical system’s constraints into account. Due to the fact that many space heaters might demand more current collectively than the circuit can handle, trying to operate multiple heaters from a single outlet may cause breakers to trip.

Additionally, it is unsafe to use extension cords to support additional heaters. Because space heaters require such high electrical loads, extension cords are not made to handle them and can overheat, perhaps starting fires.

Safe Nighttime Operations

As long as they are positioned and used safely, space heaters can run continuously. They must never be used though while you are sleeping. Continuous supervision is required to quickly turn off the space heater in the event of any unanticipated threats.

Space Heater-Specific Breakers

As long as the circuit it is attached to isn’t overloaded, it’s usually not required to use a separate breaker just for a space heater. However, it could be a good idea to consider a dedicated breaker if you want to use space heaters for an extended amount of time or in the same room as other high-amperage equipment.

Space heaters and other large appliances shouldn’t be used on the same circuit because this increases the risk of breaker trips and fires. To avoid overloading the circuits in your room when plugging in space heaters, become familiar with the circuits there.

If your space heater requires more power than your electrical system can provide, or if you plan to use space heaters as your main source of heating, hiring an electrician to add a new circuit to your breaker box is a smart move.

Safety Advice For Space Heaters

Even while they can offer useful extra heat, space heaters can be dangerous if not utilized properly. Take into account the following advice to ensure safety and lower the danger of fires:

  1. Place your space heater on a level, non-carpeted surface by selecting one from the list below. If there is carpeting, place a piece of plywood below to keep the heater from coming into direct contact with the carpet.
  2. Placement is Important: Keep space heaters away from children’s beds and anything that could catch fire, including oily rags or gas cans. Keep children at least five feet from anything that can catch fire, such as bedding and drapes.
  3. Childproof and Pet-proof: Create a secure perimeter around the space heater if you have kids or pets to avoid unintentional contact. To reduce the risk of flames or burns, erect barriers a few feet away from the heater.
  4. When not in use, the space heater should always be unplugged. Instead than pulling on the cord, grab the plug itself to detach it. Never use a space heater with a frayed or damaged cord; instead, check the cord frequently for wear or damage.
  5. Never connect a space heater to a power strip since they are not made to withstand the significant electrical loads that they produce. Utilizing a power strip may result in overheating and possible fire risks.
  6. Never leave a space heater running unattended. Continuous Supervision. Make sure someone is there to keep an eye on the heater to lower the likelihood of mishaps.


Although they can be a useful source of extra heat, space heaters must always be used safely. You can take use of the advantages of space heaters while lowering the hazards involved with their use by following safety precautions, such as appropriate positioning, avoiding overloading circuits, and constant supervision. To use space heaters securely, keep in mind that you must be aware of their electrical needs and take all essential safety measures to avoid mishaps and fires. Keep warm and be careful!
