500W Space Heaters: Are They Worth It?

As winter gets closer and it gets colder, people try to find cheap and good ways to stay warm without turning up the heat. In your home, 500-watt space heaters give heat to small to medium-sized rooms. These small heaters can save energy if used correctly to provide extra heat.

What is a 500 Watt Space Heater?

A 500-watt space heater is a portable electric heater that uses 500 watts of power. The wattage shows how much energy the appliance uses. More watts mean it can heat more. Five hundred-watt heaters are smaller in size and perfect for heating smaller rooms in your home. They can also warm up compact spaces effectively. These smaller heaters can warm up small areas such as offices or bedrooms. Five hundred-watt heaters can raise the temperature of a 10 x 10-foot room by about 10-15 degrees Fahrenheit.

How Do 500 Watt Space Heaters Work?

500-watt space heaters work by converting electricity into heat. We use different technologies to generate and distribute warm air.

Radiant or infrared heaters have metal heating elements that emit infrared heat. This heat directly warms objects in its path. Ceramic heaters use a ceramic heating element and fan to blow warm air throughout the room. Oil-filled heaters circulate oil that retains and emits heat. In all types, a fan or internal convection circulates and spreads the heat evenly around the room.

Benefits of Using a 500 Watt Space Heater

There are several advantages to using these low-wattage heaters:

The 500-watt models are affordable, costing between $25 and $50. They are much cheaper than central heating. The heaters are portable and compact, making them easy to move from room to room. Within minutes of turning them on, you can feel the warmth because they heat up quickly. Most models have adjustable thermostats. You can control the temperature to your comfort level. Safety features like tip-over switches and overheat protection are standard. Using zone heating with a space heater minimizes energy consumption compared to heating your whole house.

Five hundred-watt heaters allow you to lower your central heating costs and still keep warm in the spaces you use the most.

Choosing the Right 500 Watt Space Heater

With so many models on the market, here are key factors to consider when selecting a 500-watt space heater:

Think about your intended use – is it for warming a personal space like an office or heating a whole room? This determines the wattage needed. When choosing a heater, think about the type you need. Radiant or infrared heaters are good for heating small areas. Ceramic and oil-filled models are better for heating larger spaces. Make sure the wattage aligns with the room size you want to heat. Prioritize safety features like tip-over switches, overheat protection, and cool-touch exteriors. Models with adjustable thermostats allow more control over the temperature. If the heater will be near where you sleep or work, check decibel levels for noise. Consider if you need wheels and handles to move it from one room to another.

When choosing a 500-watt space heater, prioritize safety first, then shop for features that align with your specific heating needs

Using Your 500 Watt Space Heater Safely

While convenient, space heaters require some safety precautions. Be sure to read all instructions thoroughly. Give the heater space and place it at least 3 feet away from furniture, curtains, and combustible materials. Keep nearby areas clear, and don't place near high foot traffic paths. Plug directly into the wall outlet, not into an extension cord or power strip. Use on a flat, even, non-flammable floor surface, not on carpets or rugs. Don't leave a heater operating unattended – always turn it off when leaving a room. Built-in or outlet timers allow the heater to turn off on a schedule automatically. Avoid using in bathrooms or other damp, high-moisture areas. Monitor frequently to ensure the heater is not overheating.

Following all safety guidelines is crucial for preventing fires or injuries when using space heaters.

Where to Place 500 Watt Space Heaters

Strategic placement is key for evenly distributing warmth. Great spots to place the heater are close to seating or work areas, in the center of a room, or near cold air returns for extra warmth. Avoid placing near window treatments, furniture, foot traffic paths, or heat-sensitive items. Try different placements to determine what works best for a room.

Using Space Heaters to Lower Energy Bills

One major benefit of space heaters is their potential to reduce central heating costs. Lower your main thermostat 3-5°F when also using a space heater to compensate. Only set the heater thermostat as high as needed for comfort. Turn on 30+ minutes before entering a room. Use zone heating and only heat rooms you occupy—match heater schedules to when you use a particular room. Always turn off and unplug when not needed.

You can stay warm and use less energy by using a lower central thermostat and space heaters strategically.

Maintaining Your Space Heater

To ensure safe and efficient operation, maintain your 500-watt space heater regularly—clean air intake filters as directed. Use compressed air to remove dust buildup on heating elements and vents. Wipe down the exterior with a soft cloth to remove dust. Inspect the power cord for damage before plugging it in. Make sure internal components are dry before turning on. Replace any damaged or faulty parts. Well-maintained heaters will have better safety and performance. Most last 3-5 years with proper care.

Safety Tips

While very useful, space heaters can pose risks if misused. Never leave a heater unattended or near flammable materials. Allow 3 feet of clearance on all sides. Plug directly into the wall with no extension cords. Don't use close water sources. Monitor for signs of overheating, like smoke or odd smells. Store safely when not in use. Always err on caution, and don't take risks with electrical appliances.

Staying Warm This Winter

A 500-watt space heater is one effective way to add heat to specific rooms. To keep warm, try these tips: insulate your home, use rugs, open curtains, heat only used spaces, keep doors open, and wear layers.

During winter, using a space heater and other methods can make your home more comfortable. 500-watt space heaters are small and can help save energy when used with central heating.


What should I consider when choosing a space heater?
