For a portable space heater, the safest and most efficient place to put it is on a hard, level floor in an open area away from foot traffic. Always maintain a 3-foot clearance around the heater, keeping it well away from flammable objects like curtains, beds, and furniture.
A well-known way to position heaters is under windows. If you do not have the space for panel heaters, you can also choose wall strip panel heaters, which are lower and longer versions. By placing heaters under the windows, you heat up cold air descending from the window glass, and avoid cold draughts along the floor.
Place the heater on a stable, flat surface such as hardwood, tile, laminate, or vinyl flooring. Avoid carpets, rugs, bedding, or upholstered furniture, which can trap heat and increase fire risk. In carpeted rooms, use a heat-resistant mat beneath the heater for added safety.
Most indoor heaters tend to dry out the air, lowering indoor humidity levels. Dry air can cause irritation to the respiratory tract, leading to symptoms like dry throat, cough, and nasal congestion. For individuals with chronic respiratory diseases like asthma or COPD, low humidity can exacerbate symptoms.
As a rule of thumb, you should allow for 3-feet of clearance in front of the heater and 6 inches to either side and above the heater.
Place space heaters on level, flat surfaces. Never place heaters on cabinets, tables, furniture, or carpet, which can overheat and start a fire. Always unplug and safely store the heater when it is not in use.
It takes time for your home to warm up and cool down. If you're not sure how long it takes, try turning the heating on about 30 minutes before you need it. You should turn it off 30 minutes before you'll stop needing it.
For individuals with COPD, temperatures below freezing (32°F / 0°C) are considered too cold and can trigger severe flare-ups, chest tightness, and shortness of breath. Even temperatures dropping below 40°F (4.4°C) can cause the dry, chilled air to irritate overly sensitive airways.
Room heaters can cause severe health and fire hazards if used improperly. Primary side effects include severe dehydration of the air triggering dry skin, throat irritation, and eye dryness. Additionally, fan heaters can circulate dust, worsening asthma, while faulty or fuel-burning units pose critical risks of fire and carbon monoxide poisoning.
For a bedroom, the safest space heaters feature no glowing elements and include automatic shut-off and tip-over protection. Oil-filled radiators (like those by De'Longhi) and modern ceramic convection heaters with cool-touch housing (such as the Dreo Solaris) are generally considered the safest options for overnight use.
If frayed, worn or damaged, do not use the heater. Never leave a space heater unattended. Turn it off when you're leaving a room or going to sleep, and don't let pets or children play too close to a space heater.
Since the heater warms the air surrounding it, all the hot air will move upwards from that height itself and we will not feel the hot air. Therefore the heaters are placed near the floor such that the hot air rises from the bottom itself and warms the entire room uniformly.
PLACE YOUR HEATER ON A FLAT, LEVEL, FIRM SURFACE.
Never put your heater on your bed, furniture, or in deep carpeting. Those are unstable surfaces that could cause the heater to tip over easily. Keep your heater on flat, hard surfaces like tabletops and hard flooring.
The heater is placed near the floor because the air currents move upwards so the hot air fills up the whole room. Whereas, an air conditioner is placed near the ceiling because the cold breeze tends to settle down. If it is placed near the floor then it will fill just the bottom of the room with cool air.
The ideal thermostat temperature in the winter is 68 degrees Fahrenheit when you're at home.
These heaters are best installed on a clear section of wall where heat can circulate freely around the room. They're often placed on exterior walls or beneath windows, which are common areas for heat loss and draughts. Positioning heaters here can help counteract cold air entering the room and improve overall comfort.
Myth 1: Room heaters cause cold or cough
Truth: Room heaters don't cause illness, but dry air can irritate your throat or skin. Use a humidifier or keep a bowl of water nearby to maintain moisture in the room.
Space heaters are inherently safe when they feature automatic tip-over shutoff, overheat protection, and a cool-to-touch exterior. Top-rated, lab-tested models like the Dreo Solaris 718 (around $50) or an oil-filled radiator like the DeLonghi Comfort Temp (around $100) are widely considered the safest for home use.
Heaters are generally safe, but they can negatively affect your health in three main ways: drying out your air and nasal passages (which makes you more susceptible to viruses), circulating indoor allergens, and causing dangerous carbon monoxide buildup if unvented gas or fuel heaters are used.
Cigarette smoking is the major cause of lung cancer and chronic obstructive pulmonary disease (COPD), which includes chronic bronchitis and emphysema. Cigarette smoke can narrow the air passages and make breathing more difficult.
Strengthening your lungs with COPD means making the muscles that control your breathing more efficient, as damaged lung tissue cannot be repaired. You can significantly improve your endurance and reduce breathlessness through targeted breathing techniques, regular low-impact exercise, and airway-clearing methods.
One of the first and most common signs of Chronic Obstructive Pulmonary Disease (COPD) is a persistent, long-term cough, often referred to as a "smoker's cough".
In most homes, Heating and Cooling (HVAC) systems drive the highest energy costs, accounting for nearly 40% to 50% of your total electricity bill. Following these, the appliances that run up your bill the most include water heaters, refrigerators, and laundry machines.
Heating and energy expert Stephen Hankinson said that one "big energy cost saver" is to make sure you have your heating off when you're not at home. For instance, if you typically arrive home from work at around 6pm on weekdays, you could set your heating to activate just as you walk through the door.
To keep your house warm in winter, prioritize blocking drafts and maximizing natural heat. Seal windows and doors with weatherstripping, use rolled towels or draft stoppers, and insulate glass with shrink film. Let sunlight warm south-facing rooms during the day, and close thermal curtains at night.
