Stop Space Heater Fuse Blowouts: Learn How to Prevent It Today

To prevent a space heater from blowing a fuse, use a dedicated circuit for the heater and avoid using extension cords. Now, space heaters can be a convenient way to keep your room warm, but they can also be dangerous if not used properly.

One common issue that people face when using a space heater is that it keeps blowing a fuse. This can be problematic, especially if you only have a limited number of circuits in your home. Fortunately, there are some simple steps that you can take to prevent your space heater from blowing a fuse.

In this article, we will discuss some of the most effective ways to avoid this common problem. By following these tips, you can enjoy a warm and cozy home without worrying about any electrical issues.

Understanding Space Heaters

Overview Of Space Heaters And Their Types

Space heaters are portable heating devices designed to warm up small areas and rooms. They come in various types, each with their specific benefits and drawbacks. Some of the commonly used types of space heaters include:

  • Ceramic heaters: These heaters contain ceramic heating elements to warm the surrounding air.
  • Radiant heaters: Radiant heaters use infrared radiation to heat objects and people in the room directly.
  • Convection heaters: The heaters warm up the air in the room and circulate it using a fan.
  • Oil-filled heaters: These heaters use an electric heating element to warm up oil inside the heater, which then heats the surrounding air.

How Space Heaters Work

Space heaters consist of heating elements that convert electrical energy into heat. The heating elements can be made of ceramic, metal, or other materials. When electricity flows through these elements, they produce heat that radiates out into the surrounding air.

The heat generated by space heaters is usually directed outwards, either through a fan or other means. The warm air circulates around the room and heats up the objects in its path.

It is essential to note that space heaters consume a lot of electricity; thus, they should be used with caution.

Dangers Of Space Heaters

While space heaters are great for heating small areas, they pose several dangers if not used correctly, including:

  • Fire hazards: Space heaters can cause fires, especially when placed too close to combustible materials such as curtains and furniture.
  • Carbon monoxide poisoning: Space heaters that run on fuel such as kerosene can produce carbon monoxide, a poisonous gas that can be fatal if inhaled.
  • Electric shocks: Faulty wiring or mishandling of space heaters can lead to electric shocks, which can cause severe injuries.

To prevent these dangers, always follow the manufacturer’s instructions and safety guidelines before using your space heater. Additionally, avoid leaving your space heater unattended, and ensure that it is placed on a stable surface, away from children and pets.

Reasons Behind Fuse Blowouts In Space Heaters

Space heaters are handy devices that help maintain the warmth inside your home. However, due to their insufficient wiring, they can often blow out a fuse causing discomfort and inconvenience. Here are the common causes of space heater fuse blowouts, and how you can avoid them.

Common Causes Of Space Heater Fuse Blowouts

A. Overloading The Circuit

  • Using multiple appliances or electronics alongside a space heater, especially on the same circuit, can overload it.
  • The excessive power consumption exceeds the circuit’s capacity, causing the fuse to trip repeatedly.

B. Faulty Wiring

  • Faulty wiring within the space heater can cause an electrical short circuit leading to a blown out fuse.
  • If you see any visible damage to the wires, stop using the space heater immediately, and have it repaired by a professional.

C. Using The Wrong Type Of Fuse

  • Each appliance requires a specific type of fuse designed to handle varying levels of power.
  • Using the wrong fuse can lead to serious electrical damage, and in severe cases, result in electrical fires.

Explanation Of How Blowouts Occur

When an electrical circuit becomes overloaded, the circuit breaker will trip, causing the fuse to blow. A blown-out fuse, also called a “blown fuse,” occurs when too much electrical current flows through the circuit. It cuts off the connection to protect the device from further damage.

Keeping your space heater safe from fuse blowouts involves avoiding overloading circuits, inspecting for electrical shorts, and ensuring you use the right type of fuse. Guarantee the prolonged use of your space heater by following these tips.

Preventing Fuse Blowouts

Space heaters are a great way to keep you warm and cozy during the colder months. However, if you’re not careful, your space heater can blow a fuse, which can be a hassle to fix. In this section, we’ll discuss some tips to prevent your space heater from blowing a fuse.

Maintaining Your Space Heater Properly

Proper maintenance of your space heater is essential to prevent it from blowing a fuse. Here are some tips:

  • Follow the manufacturer’s instructions for maintenance.
  • Check and replace the filters regularly.
  • Lubricate the motor as per the owner’s manual.

Cleaning The Unit Regularly

Dirt and dust accumulation can cause the fuse to blow. Therefore, it’s crucial to keep your space heater clean. Here are some cleaning tips:

  • Dust your space heater regularly.
  • Turn off and unplug the unit before cleaning.
  • Clean the grill with a vacuum or a duster.

Checking For Frayed Wires

Frayed wires can create a short circuit, which can trip the fuse. Therefore, you should regularly check the wires for any damage. Here are some tips:

  • Inspect the wires for any tears, crimps, or cuts.
  • Replace any damaged wires immediately.
  • Keep the wire connections clean.

Proper Storage

Proper storage of your space heater can prolong its lifespan, prevent it from getting damaged, and keep it from tripping the fuse. Here are some tips:

  • Store the unit in a dry and dust-free area.
  • Keep it in its original box or a clean plastic bag.
  • Store the unit away from children or pets.

Tips For Avoiding Overloading The Circuit

Overloading the circuit is a common cause of blowing the fuse. Here are some tips to avoid overloading the circuit:

  • Don’t use too many high-wattage appliances on the same circuit.
  • Unplug any appliances that you’re not using.
  • Use the space heater on a different circuit than other high-wattage appliances.

Using The Right Type Of Fuse

Using the wrong type of fuse can cause the space heater to blow the fuse. Therefore, it’s crucial to use the right type of fuse. Here are some tips:

  • Use the fuse that is recommended by the manufacturer.
  • Check the fuse rating before replacing it.
  • Don’t replace the fuse with a higher or smaller rating.

By following these tips, you can prevent your space heater from blowing a fuse. Regular maintenance, cleaning, checking for frayed wires, proper storage, avoiding overloading the circuit, and using the right type of fuse are essential steps to keep your space heater functioning correctly and efficiently.


By following the simple steps outlined above, you can prevent your space heater from blowing a fuse. Remember to always check the wattage, ensure proper placement and ventilation, use extension cords with caution, and clean the heater regularly. It is important to prioritize safety when using space heaters to avoid potential hazards such as electrical fires.

Investing in a good quality space heater can also go a long way in preventing blown fuses and ensuring efficient heating. So, take the necessary precautions, and enjoy a warm and cozy winter season without any worries. Stay safe, stay warm, and happy heating!
