Are Space Heaters Cheaper Than Gas Heat?

Space heaters can be more cost-effective than gas heat due to their lower initial cost and the ability to heat a specific area. However, it is important to consider the long-term costs, efficiency, and safety features of both options before making a decision.

Are Space Heaters Cheaper Than Gas Heat?


Factors To Consider

Are Space Heaters Cheaper Than Gas Heat?

Space heaters and gas heating systems are two popular options for keeping your home warm during the colder months. But when it comes to deciding which one is cheaper, there are several factors to consider. Let’s take a closer look at each factor to help you determine which option is more cost-effective.

Energy Efficiency

  • Gas heating systems: Gas heaters are generally more energy efficient than space heaters. They are designed to provide heating to the entire home and are capable of maintaining a consistent temperature throughout the space.
  • Space heaters: Space heaters typically have lower energy efficiency compared to gas systems. They are designed to add extra heat to specific areas or rooms rather than heating the entire house.

Initial Cost

  • Gas heating systems: Gas heating systems can be more expensive upfront due to the installation costs. You’ll need to purchase not only the heater but also the necessary ductwork and vents for proper installation.
  • Space heaters: Space heaters are generally more affordable upfront. You can easily find a variety of space heaters at reasonable prices in the market.

Operating Costs

  • Gas heating systems: The cost of operating gas heating systems largely depends on the price of natural gas in your area. Keep in mind that gas heaters distribute heat to the entire home, which can result in higher monthly costs.
  • Space heaters: Space heaters tend to have lower operating costs as they only heat specific areas or rooms. However, if you frequently use space heaters in multiple rooms, the costs may increase.


  • Gas heating systems: Gas heaters typically have a longer lifespan than space heaters. With regular maintenance, a gas heating system can last for 15 to 20 years.
  • Space heaters: Space heaters generally have a shorter lifespan compared to gas heating systems. On average, they can last for 5 to 10 years, depending on usage and maintenance.

Safety Features

  • Gas heating systems: Gas heaters require proper ventilation and regular maintenance to prevent the risk of carbon monoxide buildup. However, modern gas heaters are equipped with safety mechanisms such as carbon monoxide detectors and automatic shutoff features.
  • Space heaters: Space heaters come with built-in safety features like tip-over switches and overheat protection. However, there is still a higher risk of fire or burns if not used properly.

Considering these factors, it is clear that gas heating systems are generally more cost-effective in the long run due to their higher energy efficiency and longer lifespan. However, if you only need to heat specific areas or rooms and are looking for a more affordable upfront option, space heaters can be a suitable choice.

Ultimately, the decision depends on your specific needs, budget, and heating requirements.

Energy Efficiency

Space heaters and gas heat are two popular options for quickly warming up a room or space during the colder months. But when it comes to cost, are space heaters cheaper than gas heat? One key factor to consider is energy efficiency, as it directly affects the operating cost of both types of heating systems.

In this section, we will explore energy efficiency ratings, compare the efficiency of space heaters and gas heat, and examine how different types of space heaters stack up against gas heat.

Understanding Energy Efficiency Ratings

Energy efficiency ratings play a crucial role in determining how efficient a heating system is. They help consumers make informed decisions by providing insights into a unit’s energy consumption and performance. Here are some key points to understand about energy efficiency ratings:

  • Energy efficiency ratings are standardized and often displayed on heating units, allowing consumers to compare different models easily.
  • The most common energy efficiency rating for gas heat is annual fuel utilization efficiency (afue), which measures how efficiently the unit converts fuel into heat over a year.
  • Space heaters typically display the energy efficiency rating as a percentage, which represents the amount of energy converted into heat.
  • Higher energy efficiency ratings indicate more efficient heating systems, resulting in less wasted energy and lower operating costs.

Comparing Space Heaters And Gas Heat Efficiency

Now let’s compare the efficiency of space heaters and gas heat. Here are the key points to consider:

  • Gas heat systems, such as furnaces, can achieve high afue ratings, often ranging from 80% to 98%. This means that a significant portion of the energy derived from the fuel is converted into heat, resulting in efficient heating.
  • Space heaters, on the other hand, vary in efficiency depending on the type and model. Electric space heaters are generally more efficient than fuel-burning ones, with energy efficiency ratings ranging from around 80% to 100%. However, keep in mind that electricity costs are typically higher than gas costs, affecting overall affordability.
  • While gas heat tends to have higher energy efficiency ratings, space heaters offer the advantage of zoning, allowing you to heat specific areas instead of an entire house. This targeted heating can result in energy savings.
  • It’s important to note that the size of the space being heated, insulation, and usage patterns can all influence the overall efficiency of both space heaters and gas heat systems.

How Different Types Of Space Heaters Compare To Gas Heat

Different types of space heaters have varying levels of energy efficiency when compared to gas heat. Here’s a breakdown of how they compare:

  • Electric space heaters: These are generally more energy-efficient than fuel-burning space heaters. They convert almost all the electricity used into heat, resulting in an efficiency rating of around 80% to 100%. However, they can be more expensive to operate due to higher electricity costs.
  • Infrared space heaters: These heaters use infrared radiation to directly warm objects and people in a room. While they may not have an official energy efficiency rating, they are known for providing targeted and efficient heating by minimizing heat loss to the surrounding air.
  • Oil-filled space heaters: These heaters use electricity to heat oil stored inside the unit and radiate heat into the room. They have an energy efficiency rating of approximately 100% since all the electricity consumed is converted into heat. However, they may take longer to reach the desired temperature.
  • Propane and natural gas space heaters: These types of fuel-burning space heaters have lower energy efficiency ratings compared to electric space heaters, typically ranging from 50% to 90%. They require proper ventilation to prevent carbon monoxide buildup but can be cost-effective in areas with lower gas prices.

Understanding the energy efficiency of space heaters and gas heat systems is essential for making an informed decision when it comes to affordability and overall heating effectiveness. By considering energy efficiency ratings and the specific characteristics of different heating options, you can choose the option that best suits your needs, preferences, and budget.
