Key Factors in Choosing the Best Energy Efficient Space Heater
When selecting the most energy efficient space heater for your home, it’s important to consider a range of features that impact performance, safety, and overall cost-effectiveness. Here’s what to look for:
Performance & Efficiency
Room size and wattage: Match the heater’s wattage to the room size. As a rule of thumb, you’ll need about 10 watts per square foot. A 750-watt unit may be enough for small bedrooms, while larger living spaces may need up to 1,500 watts.
Type of heating technology: Different types of space heaters offer unique benefits. Convection heaters are great for full-room warmth, infrared heaters provide instant, targeted heat, and oil-filled models maintain steady warmth with lower energy draw over time.
Energy-saving features: Look for adjustable thermostats, multiple heat settings, and programmable timers to reduce energy usage while maintaining comfort.
Safety First
Built-in safety protections: Choose models with tip-over shutoff, overheat protection, and cool-touch exteriors. These are essential for homes with pets, children, or older adults.
Certified safety standards: Confirm your heater has certifications from UL, ETL, or CSA to ensure it’s been tested for electrical and fire safety.
Comfort & Convenience
Noise level: Some people prefer silent operation, especially in bedrooms or home offices. Oil-filled and infrared heaters tend to be quieter than ceramic models with fans.
Portability and controls: If you plan to move your heater around, lightweight designs with handles or wheels are a plus. Remote controls and digital displays add to ease of use.
Aesthetic and brand reputation: Choose a style that fits your room’s decor and buy from a trusted brand with a solid warranty. This adds peace of mind and product longevity.
How Space Heaters Work
When you’re choosing the most energy-efficient space heater, it helps to understand the technology behind how these devices generate and distribute heat. The two most common types of heating methods are convection and infrared – each offering unique benefits depending on your home and comfort needs.
Convection Heating
Convection space heaters work by warming the air around them using an internal heating element. A fan then circulates that warm air throughout the room, creating even heat distribution. Some models, such as oil-filled radiators, use convection heating without a fan. Instead, the heated oil inside the fins radiates warmth gradually, making them ideal for maintaining consistent temperature over time with less noise.
These heaters are great for closed, insulated spaces where keeping a steady ambient temperature is the goal. While they may take longer to warm up, they’re effective for heating entire rooms when used properly.
Infrared Heating
Infrared heaters function more like the sun, radiating heat that warms people and objects directly rather than heating the surrounding air. This makes them a great option for targeted, instant warmth – particularly useful in drafty or poorly insulated areas.
Because they don’t rely on air circulation, infrared heaters are quieter than many fan-forced models and are less likely to dry out the air. If you’re looking to heat a specific spot, like your work desk or favorite reading chair, an infrared heater is one of the most energy-efficient choices available.
Choosing the Right Energy Efficient Space Heater for Your Home
Selecting the best energy-efficient space heater comes down to matching the right model to your space and your home’s characteristics. In the Bay Area, where charming older homes often come with cold drafts, these factors matter even more.
Match Heater Wattage to Room Size
Heater wattage directly impacts both performance and energy use. As a general guideline:
- Small rooms (up to 150 sq. ft.) – Opt for a 750-watt heater
- Medium rooms (150-300 sq. ft.) – Use a 1,000-watt model
- Larger rooms (300+ sq. ft.) – A 1,500-watt heater is typically required
Choosing a heater that’s too powerful for the space wastes energy, while an underpowered unit will struggle to maintain warmth. Look for models with adjustable wattage or thermostats for added flexibility.
Consider Your Home’s Insulation
Even the most energy-efficient space heater will have to work harder if your home is poorly insulated. Drafty windows, unsealed doors, and thin walls can lead to rapid heat loss. Before relying solely on your space heater, take some time to seal gaps and improve insulation.
In multi-room homes, HVAC zoning systems offer another energy-saving option by directing heat exactly where you need it. They allow you to maintain comfort across different areas without overworking a single appliance.
By carefully considering your room size, insulation quality, and heating technology, you can choose the most cost-effective and comfortable space heater for your home – and keep those chilly Bay Area nights at bay.
Types of Energy Efficient Space Heaters
⚠️ While space heaters can provide quick warmth in specific situations, Bellows Plumbing, Heating, Cooling & Electrical recommends installing a professionally designed heating system for the safest, most energy-efficient long-term solution. Central systems offer better comfort control, lower operating costs, and peace of mind – especially in older homes with outdated wiring or insulation.
We touched upon some space heater basics, but let’s explore a few of the common types available in more detail. These factors might help narrow your search for the best energy-efficient space heaters for your specific needs.
1. Ceramic Heaters
Ceramic heaters are among the most popular. They use a ceramic heating element to heat up quickly, and they often have built-in fans to spread the warmth. They’re generally lightweight and portable, making them a convenient choice for supplemental heating in many rooms.
The Kismile Small Space Heater for Indoor Use is a great example of one with these features. Look for features like tip-over safety switches, overheat protection, and cool-touch exteriors when considering the best energy-efficient space heaters in this category.
2. Infrared Heaters
Infrared heaters are known for their quiet operation and for providing a gentle, radiant warmth that some find more comfortable than the forced hot air of ceramic heaters. These types of heaters work particularly well for people who experience dry skin during colder months because they don’t dry out the air as much as convection heaters.
A great example of an infrared heater is the Duraflame 3D Infrared Electric Fireplace Stove.
3. Oil-Filled Heaters
Oil-filled heaters use oil that’s heated by electricity to create comfortable, radiant heat. Once the oil is heated, these can continue to provide warmth for a while, even after you turn them off, so they use less electricity overall.
This can be a good option for longer-term use, especially in smaller rooms where you want to maintain a consistent temperature.
You also won’t get the blast of hot air that some other best energy-efficient space heaters provide, but it takes them a while to fully warm up a space. They also have that old-fashioned radiator feel.
Some even have a timer feature, making them great for bedrooms as you can set them to automatically shut off a few hours after you’ve gone to sleep.
The Real Cost of Using the Best Energy Efficient Space Heaters in the Bay Area
While the Bay Area may not have the nation’s highest energy rates, electricity costs can still add up-especially during colder months. That’s why choosing the best energy efficient space heaters is key to staying warm without inflating your utility bill.
Look for features that help control energy usage, such as adjustable thermostats, programmable timers, and multiple heat settings. These functions allow you to customize warmth to your comfort level while minimizing unnecessary energy draw.
Wattage and Why It Matters
A space heater’s wattage rating directly impacts how much energy it uses and how effectively it can heat a room. Most standard models come in 750 to 1,500 watts. Lower-wattage heaters are great for smaller rooms or personal spaces, while higher-wattage options better suit open living areas.
Fortunately, even the most powerful energy-efficient space heaters are compatible with common 120-volt home outlets, making them accessible for most households.
To maximize efficiency, run your heater only when needed-such as to give a room an initial boost of warmth-and then rely on thermal curtains, layered clothing, or insulated blankets to retain heat. This approach lets you enjoy the comfort of extra warmth without constantly drawing power.
Essential Safety Features of Space Heaters
While those vintage homes might have a special charm, older wiring can be an issue. Using the best energy-efficient space heaters with built-in safety features is essential for peace of mind, especially for families.
Look for Features Like:
- Tip-Over Switch: These shut the heater off automatically if it’s knocked over, reducing fire risks.
- Overheat Protection: This automatically cuts off the power if the heater gets too hot.
- Cool-Touch Exteriors: Prevents burns if accidentally touched. Perfect for households with small children.
- Safety Certifications: Look for labels indicating the space heater has been tested for safety by a reputable third-party lab. Some examples of these third-party testers are; UL Solutions, ETL (Intertek), or CSA.
A tip for extra caution is to make sure to plug space heaters directly into the wall outlet. Using extension cords increases the risk of overheating. Avoid using these unless absolutely necessary.
Maximizing Energy Savings
Remember, energy efficiency doesn’t just come from choosing the best energy-efficient space heaters. You also have to use them strategically to reduce energy waste and heating costs in the long run. Staying informed about California’s water heater code compliance can also help ensure your heating systems operate safely and efficiently.
A Few Energy-Saving Tips:
- Utilize Programmable Timers: Turn the heater off when you leave the room or use a timer to automatically shut it off at a certain time. Some models even let you schedule temperature changes based on the time of day.
- Dress Warmly: Layer up those clothes. That extra sweater or pair of thermal socks can help your space heater maintain a lower setting without compromising comfort.
- Seal Up Drafts: The Bay Area’s iconic fog rolls in bringing with it chilly air. Properly sealing windows and doors minimizes heat loss and helps your heater maintain your ideal temperature without working harder than it needs to.
- Use Curtains Strategically: Open curtains during the day to let in natural warmth from the sun, and close them at night to prevent heat from escaping through windows.
- Heat Only the Space You’re Using: Don’t waste energy heating rooms that are unoccupied. Close doors to unused areas and focus on zone heating the spaces you spend the most time in.
By combining smart usage habits with the right heater settings, you can significantly lower your energy bills while staying comfortable during cooler months.

Frequently Asked Questions About Energy Efficient Space Heaters
What type of space heater is most energy efficient?
Both infrared and oil-filled heaters have the potential to be highly energy-efficient because they provide radiant heat rather than forced hot air. However, what is “best” for your situation comes down to room size, features, budget, and preference.
It is also worth considering portable DeLonghi Mica panel heaters for the rooms you use most. Their low wattage and adjustable thermostat make them energy-saving options that also happen to be very stylish.
How do I determine the right wattage for my space heater?
The right wattage depends on the size of your room. As a general rule, you need about 10 watts per square foot of space. For example, a small 100 square foot room would need a 1000-watt heater. However, factors like insulation and ceiling height can affect this, so it’s often best to choose a heater with adjustable power settings.
What’s the difference between convection and infrared space heaters?
Convection heaters warm the air in a room, which then circulates to heat the entire space. They’re great for heating enclosed areas over longer periods. Infrared heaters, on the other hand, directly warm objects and people in their path, providing instant heat. They’re more efficient for spot heating or in poorly insulated spaces.
What space heater is the cheapest to run?
Generally speaking, infrared heaters tend to be more cost-effective than convection models due to radiant heat technology, and how they warm up objects directly. However, the exact answer will be tied to the specifics of the heater model and usage habits.
It is helpful to remember that even the best energy-efficient space heaters still use electricity. Minimizing runtime, lowering wattage when possible, using timers, and taking steps to insulate your home properly, can help keep your heating bills in check, even when choosing less powerful heater models.
Are oil-filled heaters more energy efficient than other types?
Oil-filled heaters can be very energy efficient, especially for long-term use. Once the oil is heated, these heaters can continue to provide warmth even after being turned off, using less electricity overall. They’re particularly efficient in smaller, well-insulated rooms where you want to maintain a consistent temperature.
What is the most energy-efficient heater to buy?
Again, there is no one-size-fits-all “best” answer, especially when thinking about costs. Infrared heaters excel at quickly heating a room without significant air drying. On the other hand, the continuous warmth of an oil-filled model (like an old radiator) might appeal to you.
Or maybe you live in an area prone to power outages and are interested in options powered by natural gas or propane as a backup. Consider all the factors we’ve discussed in addition to what matters to your particular circumstances.
