During the cold winter months, space heaters present a practical and budget-friendly option to keep your home cozy. Available in various sizes and designs, you can find heaters suitable for everything from compact office spaces to large living areas. However, it’s crucial to exercise caution, as improper use of space heaters can lead to fire hazards and accidents.
Before purchasing a space heater, it’s important to consider several factors. From examining safety features and selecting the appropriate size to correct placement and avoiding the use of smart plugs, here’s all you need to know to safely enjoy the benefits of these devices.
Look for Essential Safety Features
The tip-over switch stands out as a key safety feature in any space heater. If a unit is accidentally toppled, this feature will automatically shut it off, significantly reducing the risk of fire. Nowadays, most contemporary heaters come equipped with this switch, but if you’re looking at older models, confirm that it includes this essential feature. Heaters lacking a tip-over switch can pose serious fire risks if knocked over.
It’s also wise to look for products with third-party safety certifications, such as those from Underwriters Laboratories (UL) or Intertek Group (ETL). These certifications indicate that the device has undergone rigorous testing to meet high safety standards, allowing you to use them with peace of mind.
Determine the Right Size and Type

Whether you’re trying to warm up an expansive studio or a small office, you’ll find space heaters specifically designed for various room sizes. Always check the manufacturer’s specifications regarding the size of the room the heater is intended for, ensuring it meets your requirements. Don’t simply choose one based on online reviews—it may not be suitable for your specific space.
Also, consider the type of heater. Some models focus on directional heat and quickly blow out warm air like a fan, while others, such as radiant heaters, gradually warm the entire area. Radiant heaters are often preferred for larger spaces and prolonged heating, whereas directional units typically heat up more rapidly.
Avoid Using Extension Cords
Space heaters draw considerable power, so they should always be plugged directly into a wall outlet. Most models are not designed to operate with extension cords, and doing so can lead to electrical problems or damage. Be sure to consult the instruction manual regarding this guideline. If you need the heater to be positioned far from an outlet, opt for models that come with long power cords.
Do Not Use Smart Plugs

While some heaters may work with smart plugs, it’s generally not advisable to mix the two due to the fire hazards involved. Accidental activation of a heater left unattended can lead to serious risks. If you opt to combine a smart plug with a space heater, ensure you monitor both the heater and your mobile app closely for safety.
Unplug When Not in Use
It’s especially important to unplug space heaters when they are not in operation, especially in homes with children or pets. You want to prevent anyone from accidentally turning the heater on or tripping over its cord. Unplugging offers a straightforward solution to avoiding unsupervised accidents; once the heater is disconnected, the risk of incidents effectively diminishes.
Choose a Safe Location
It’s crucial to keep space heaters away from flammable materials or furniture. Even non-flammable items can be damaged or warped by the intense heat that heaters emit. Temperatures next to the heater can exceed 100 degrees Fahrenheit, so it’s vital to place the unit in an area out of reach of children and pets. Regularly inspect the surroundings to ensure nothing has accidentally been placed too close to the heater’s heat output.
