Surge Protector Safety: Can You Use One With a Space Heater?


Understanding The Basics Of Space Heaters And Surge Protectors

Are you wondering if it is safe to use a surge protector with a space heater? Well, the answer is not as straightforward as you might think. Space heaters are a common source of home heating that can provide warmth and comfort during the colder months.

However, they can also pose a potential fire hazard if not used safely. That’s where surge protectors come into play. In this blog post, we will cover the basics of space heaters and surge protectors, including the different types of space heaters available in the market, risks and hazards associated with space heaters, and an introduction to surge protectors and how they work.

Different Types Of Space Heaters Available In The Market

There are several different types of space heaters available in the market, each with its unique features and benefits. Understanding the differences between these types can help you make an informed decision when choosing the best option for your needs.

Here are the most popular types of space heaters:

  • Electric space heaters: These are the most common type of space heaters, and they come in different sizes and styles. They use electricity to generate heat and are portable, making them easy to move around the house.
  • Propane heaters: These are often used in outdoor spaces, like patios or garages, and can run on propane gas. They generate heat quickly and are easily portable.
  • Kerosene heaters: These heaters use kerosene as fuel and are suitable for both indoor and outdoor spaces. They are portable, but they require proper ventilation as they emit harmful gases.

Risks And Hazards Associated With Space Heaters

Space heaters can be a potential fire hazard if not used correctly. Here are some of the risks and hazards you should be aware of:

  • Fire hazard: Space heaters can cause fires if they are placed too close to combustible materials like curtains, rugs, or carpets.
  • Carbon monoxide poisoning: If a space heater is not adequately ventilated, it can produce carbon monoxide (co), a toxic gas that can cause severe health problems, including death.
  • Electric shock: Faulty wiring or defects in the space heater can cause electric shock, which can be fatal.

Introduction To Surge Protectors And How They Work

A surge protector is a device that protects electronic devices from voltage spikes. It provides a barrier of protection between your electronics and the electrical source, preventing voltage spikes from causing damage. Here’s how it works:

  • The surge protector detects voltage spikes and diverts excess voltage to the grounding wire, protecting the connected devices from damage.
  • It also provides protection against power surges, which can occur when there is a sudden increase in the amount of electricity in the power grid.

Using a surge protector with a space heater can offer protection against electrical hazards and prevent fires. However, it’s essential to use the correct type of surge protector and never overload the circuit. Keep the above safety tips in mind while using a space heater, and you’ll be able to enjoy its warmth and comfort safely.

Analyzing The Compatibility Of Surge Protectors And Space Heaters

Space heaters provide warmth and comfort during cold seasons, but they also consume a lot of electricity. And this may lead to electrical surges that can damage your space heater or other appliances. A surge protector is an excellent device designed to prevent electrical surges from damaging your appliances.

But can you use a surge protector with a space heater? In this post, we will examine the compatibility of surge protectors and space heaters and provide factors to consider when choosing a surge protector for your space heater.

Understanding The Electrical Load Of Space Heaters

Space heaters are powerful electrical appliances that consume a lot of electricity. Before using a surge protector with a space heater, it’s vital to understand the electrical load of your space heater. The electrical load is measured in watts and refers to the amount of power your space heater needs to operate smoothly.

Here are some factors that may affect the electrical load of your space heater:

  • Power settings: Most space heaters have different power settings. The higher the power setting, the more electricity your heater will consume.
  • Thermostat settings: Turning the thermostat up means the space heater will work harder to reach the desired temperature.
  • Room size: A larger room may require a more powerful space heater that consumes more electricity.

Evaluating The Electrical Capacity Of Surge Protectors

Surge protectors come in different electrical capacities that are measured in joules. The higher the joule rating, the more electrical energy the surge protector can withstand. When choosing a surge protector for your space heater, ensure that the electrical capacity of the surge protector is higher than the electrical load of your space heater.

Here are some factors to keep in mind:

  • Never overload a surge protector: Overloading a surge protector can lead to electrical fires or damage to your appliances.
  • Check the electrical load of your space heater: Ensure that the watts rating of your space heater is below the joules rating of your surge protector.
  • Choose a surge protector with a high joule rating: For space heaters, it’s best to choose a surge protector with a joule rating of at least 2000.

Factors To Consider When Choosing A Surge Protector For A Space Heater

Choosing the right surge protector for your space heater can be challenging, but it’s crucial to safeguard your appliance against electrical surges. Below are some factors to consider when selecting a surge protector for your space heater:

  • Type of surge protector: There are different types of surge protectors, including basic, standard, and premium models. Choose a surge protector that meets your protection needs and budget.
  • Number of outlets: Ensure that the surge protector has enough outlets to accommodate your space heater and other electrical devices.
  • Cord length: Choose a surge protector with a long cord that can reach your electrical outlet comfortably.
  • Ul rating: Look for a surge protector that has a ul (underwriters laboratories) rating, which means it has undergone rigorous testing and meets safety standards.

Finally, note that a surge protector is not a substitute for responsible use of electrical appliances like space heaters. Always read the instructions, follow safety guidelines, avoid overloading your surge protector, and never leave your space heater unattended. With a proper surge protector in place, you can enjoy the warmth and comfort of your space heater without worrying about electrical surges damaging your appliance.


Summing up, using a surge protector with a space heater is a debatable topic with no clear-cut answer. While some believe it’s a safe option, others argue that it increases the risk of a fire hazard. It’s important to note that both devices use a significant amount of power, and if not handled properly, there’s a possibility of electrical overload and overheating.

It’s, therefore, crucial to follow the safety instructions and precautions provided in the user manual of both devices. Additionally, using heavy-duty extension cords can be a reliable alternative to a surge protector, as they’re designed to handle the power of high wattage appliances.

Ultimately, it’s up to the individual to weigh the risks and make an informed decision on whether to use a surge protector with a space heater or not.
