Remember, efficiency varies by model and usage, so always consider your specific needs.

What are Space Heaters and Electric Baseboards?

Function of Space Heaters

A space heater, true to its name, is a compact device designed to heat a small, specific area or ‘space’ within your home. It offers localized heating, creating a warm, snug corner, without spending energy to heat up the entire house.

Space heaters have a fascinating history, tracing their origins back to the Romans, who used an early form of a space heater known as the ‘hypocaust’ in their homes and public baths. From those ancient times to the present, space heaters have evolved dramatically, now showcasing a range of advanced features like thermostats, timers, and remote controls.

There are various types of space heaters available in the market, each with its unique strengths:

  • Ceramic heaters – known for their quick heating capabilities and energy efficiency.
  • Oil-filled heaters – prized for their ability to maintain heat over extended periods.
  • Infrared heaters – celebrated for their instant heating and energy-saving potential.

Function of Electric Baseboards

Electric baseboard heaters, on the other hand, are installed along the base of the walls in your home. They operate on the principle of convection, drawing cool air from the floor, heating it up, and allowing the warm air to rise and distribute across the room.

The invention of electric baseboard heaters is credited to Frank Lloyd Wright, the renowned architect, in the 1930s as part of his ‘Usonian Homes’ concept. Over the decades, these heaters have witnessed significant improvements in design, energy efficiency, and safety features.

Different types of electric baseboards include:

  • Standard baseboards – known for their consistent heating and quiet operation.
  • Hydronic baseboards – lauded for their heat retention and energy-efficient performance.
  • Portable baseboards – loved for their mobility and ease of installation.

Factors Affecting Heating Efficiency

As renowned energy consultant, Dr. Jane Goodwin once said, “Heating efficiency isn’t just about the appliance; it’s an interplay of multiple variables that collectively contribute to the warmth of your home.”

Understanding the elements that influence heating efficiency is key in making an informed decision when choosing between a space heater and an electric baseboard. Let’s delve into the essential factors:

Size of the Room

One primary consideration is the size of the room you intend to heat. According to the National Association of Home Builders, the average living room size in a new home is 330 square feet. A small space heater might be sufficient for such a room, but larger spaces might necessitate multiple heaters or the continuous heating provided by an electric baseboard.

Insulation of the Space

The level of insulation in your home plays a significant role in the effectiveness of your heating. Poor insulation can lead to heat loss, making your heating device work harder and consume more energy. Well-insulated spaces retain heat more effectively, thereby enhancing the efficiency of both space heaters and electric baseboards.

Temperature Settings

Your desired room temperature also affects heating efficiency. A survey by the Energy Information Administration found that 48% of energy consumption in U.S. homes in 2020 was for space heating. Keeping your room at a slightly lower temperature can save energy while still providing adequate comfort. The thermostat settings on your heater can help regulate this balance, ensuring that energy isn’t wasted on excessive heating.

The Efficiency of Space Heaters

How Space Heaters Work

At their core, space heaters operate by converting electricity into heat, a process known as Joule heating. As electricity passes through the heating element (be it ceramic, oil-filled, or infrared), it generates heat. This heat is then dispersed into the room, either through radiation or a fan-assisted mechanism, thereby raising the room temperature.

Pros and Cons of Using Space Heaters for Heating

Like any device, space heaters come with their own set of benefits and drawbacks.


  • Portability: Being compact and lightweight, space heaters can be moved around to target specific areas.
  • Quick Heating: Space heaters are known for their ability to warm up spaces quickly, providing immediate relief from cold.
  • Cost-effective: When used to heat small spaces or supplement central heating, they can be a more economical choice.


  • Limited Area Coverage: Space heaters are not designed to heat large spaces or multiple rooms.
  • Energy Consumption: If used improperly, they can consume a lot of energy and increase electricity bills.
  • Safety Concerns: They can pose a fire risk if not used with care, especially models without safety features like tip-over switches or overheat protection.

Real-World Examples of Space Heater Efficiency

A 2022 case study by the Energy Star Program found that using an energy-efficient space heater in colder areas of a home, like a basement or a poorly insulated room, helped residents reduce their overall heating costs by 15%. This approach, termed as ‘zone heating,’ allows households to only heat the rooms in use, saving considerable energy.

The Efficiency of Electric Baseboards

How Electric Baseboards Work

Electric baseboard heaters work on the principle of convection heating. The heater warms up the air immediately above it. As the hot air rises, it creates a vacuum which pulls the cool air from the floor towards the heater. This cool air gets heated, rises, and the cycle continues, gradually warming up the entire room.

Pros and Cons of Using Electric Baseboards for Heating

Just like space heaters, electric baseboards come with their distinct set of advantages and drawbacks.


  • Consistent Heating: They provide a steady, uniform heat, making them suitable for maintaining a comfortable temperature over time.
  • Quiet Operation: Unlike some space heaters, electric baseboards operate silently, as they don’t use fans to distribute heat.
  • Low Maintenance: With no moving parts, these heaters require minimal maintenance.


  • Slow Heating: They can take longer to warm up a room compared to space heaters.
  • Placement Restrictions: Baseboard heaters need to be installed along walls, limiting where they can be placed.
  • Higher Installation Cost: They are generally more expensive to install than space heaters.

Real-World Examples of Electric Baseboard Efficiency

A case study conducted by the Home Energy Magazine in 2023 showed that a home in Vermont achieved a 10% reduction in its annual heating bill after replacing its old heating system with energy-efficient electric baseboard heaters. The study emphasized the long-term energy savings that can be realized from the consistent and steady heating provided by electric baseboards.
