As the temperature drops, plug-in heaters become a popular choice for homeowners and office workers seeking quick, convenient warmth. These portable devices promise an easy fix for chilly spaces without the need for central heating. However, while plug-in heaters offer undeniable convenience, they also come with significant risks that are often overlooked.
From fire hazards to electrical overloads, plug-in heaters can pose serious threats. Statistics show that space heaters, including plug-in models, are a leading cause of home fires during the colder months. Yet, with the right precautions and a clear understanding of their dangers, you can minimize the risks and enjoy their benefits safely.
In this blog post, we’ll explore the potential dangers of plug-in heaters, common mistakes to avoid, and essential safety tips to keep your home warm and secure this winter. Let’s dive into how you can stay both cozy and safe.
What Are Plug-In Heaters?
Plug-in heaters are small, portable heating devices specifically designed to provide supplemental warmth to localized areas in homes, offices, or other indoor environments. These heaters are often favored for their compact design and practicality, making them a convenient option when central heating is unavailable or insufficient. They are easy to use—simply plug them into a wall outlet, and they provide almost instant warmth. Whether you’re trying to keep a small bedroom cozy or add extra heat to a chilly office corner, plug-in heaters can be a quick fix.
Why Are Plug-In Heaters Dangerous?
While convenient, plug-in heaters can come with some risks, and can cause fires and other damage if you are not careful. Here are some of the more common risks.
Fire Hazards
The most obvious danger of using plug-in heaters is the risk of fire. There are many ways they can cause a fire. The first is if the element or coil used to generate heat reaches high temperatures and comes into contact with nearby objects—generally curtains or furniture. This contact causes these items to catch on fire, leading to potential property damage or even injuries.
The second way is because plug-in heaters require a constant supply of electricity, it increases the likelihood of an electrical malfunction that could spark a fire. Lastly, There is the practice of connecting multiple devices to one outlet can also increase the risk of fires as it leads to overloading the electrical outlets.
Electric Shock or Damage
Plug-in heaters are designed to convert electrical energy into thermal energy, requiring a substantial amount of electrical current to function. As they operate, these heaters pull significant power from an electrical circuit, often drawing between 1,500 and 1,800 watts. This high demand will ultimately put a strain on electrical systems, particularly in older buildings with outdated wiring. The continuous flow of high current leads to overheating of wires, potentially causing damage to electrical outlets, cords, and any connected devices.
The excessive current draw from plug-in heaters increases the risk of electrical shock, more so if the wiring is faulty or the insulation has deteriorated. Loose connections and damaged cords also expose users to live wires, elevating the chance of electric shock. When the electrical system becomes overburdened, it is prone to failures that may lead to short circuits or damaged appliances.
To mitigate these risks, several precautions should be taken when using plug-in heaters. First, ensure the electrical circuit being used can handle the heater’s power consumption without overloading. You’re better off using a dedicated circuit for these appliances. Never use an extension cord, a 2-prong adapter, or a splitter. These devices can overheat under the load of the heater, significantly increasing the risk of a fire.
Regularly inspect the heater’s cords and plugs for noticeable signs of wear or damage and replace them immediately if necessary. Always keep the heater on a flat, stable surface and away from water to prevent accidental contact that can lead to shock.
It’s best to avoid running the heater’s cord under rugs and carpets, where it can overheat or become damaged. You should consider using surge protectors or circuit breakers that can cut off the power supply if an overload is detected. This serves as an extra layer of safety.
Carbon Monoxide Poisoning
Electric plug-in heaters themselves don’t produce carbon monoxide since this gas is primarily a byproduct of burning fuels like gas, oil, and wood. However, improper use of these heaters, especially in combination with other heating appliances, can lead to scenarios where carbon monoxide becomes a concern.
For instance, if an electric heater is used in a poorly ventilated space alongside a fuel-burning appliance, the resulting increase in temperature indirectly causes such appliances to function inefficiently or to malfunction, potentially releasing carbon monoxide into the environment.
Using an electric heater to dry clothes or to warm up spaces with restricted airflow may increase humidity and temperature levels, further complicating ventilation issues. Therefore, maintaining adequate ventilation and following all safety guidelines is crucial when operating any appliance that contributes to the home heating system, as these measures collectively help prevent the buildup and release of toxic carbon monoxide gas.
Burns and Scalding
Direct contact with the surface of a plug-in heater poses a significant risk for burns and scalding because the external surface can reach dangerously high temperatures while the heater is in operation. The outer casing of the heater, particularly the areas close to the heating element, will become hot enough to cause serious skin burns upon contact. It’s doubly concerning in households with pets, children, or elderly individuals who may accidentally touch or fall against the heater, leading to painful injuries.
To avoid these hazards, it’s best to place the heater in a location where accidental contact is unlikely. Position the heater away from high-traffic areas and ensure that it doesn’t obstruct walkways or pathways within a room. It is also advisable to use a heater with safety features, i.e., a tip-over switch or an auto-shutoff mechanism that turns the heater off if it gets knocked over or overheats.
Installing a protective barrier or guard around the heater adds a layer of security by creating a buffer between the hot surface and the surrounding environment. Educating household members, especially children, about the risks of touching the heater reinforces safety.
Supervising children and pets when they’re around the heater further reduces the risk of accidental contact. Creating a safe environment by properly positioning and safeguarding the heater ensures its benefits can be enjoyed without compromising personal safety
Should You use A Plug-in Heaters?
At Gladiator Electric, we don’t recommend you use a plug-in heater. There are just too many risks, and we’ve unfortunately seen the damage when things go wrong. However, we know that some people will likely use them no matter what we tell them so here are some safety guidelines you should follow.
For starters, proper inspection and maintenance are a no-brainer, and the risk of electrical shock and damage can be mitigated with rather straightforward steps such as avoiding overloading circuits, using dedicated circuits, and having functional surge protectors.
Adequate ventilation and following safety guidelines when operating fuel-burning appliances are essential for protecting against carbon monoxide poisoning. Finally, preventing burns and scalding can easily be achieved by placing heaters in safe locations, using protective barriers or guards, and educating household members about safety precautions.
Use a Dedicated Circuit
To prevent overloading your electrical system, it’s essential to plug your heater into a dedicated circuit with no other devices or appliances on the same line. Plugging a heater into a shared circuit can trip breakers, cause overheating, or even lead to electrical fires.
If you’re unsure whether your outlet is on a dedicated circuit, consult an electrician to assess your home’s wiring. A dedicated circuit ensures that your heater gets the power it needs without compromising safety.
Turn It Off When You Leave the Area
It’s tempting to leave the heater running to maintain a cozy space, but unattended heaters are a significant safety hazard. Always turn off your plug-in heater when you leave the room or area, even if it’s just for a short time.
Additionally, many modern heaters come with built-in safety features such as tip-over shutoff and overheat protection. While these features add a layer of safety, they should never replace the precaution of turning the heater off when not in use.
