Are space heaters an effective and cost-efficient alternative for heating your home? This article examines the pros and cons of using space heaters, how to calculate savings, tips for energy efficiency, and examples of real-life cost savings.


If you live in a part of the world that experiences extreme cold weather, the heating bills can be a significant expense in your budget. Space heaters are becoming increasingly popular as a cost-effective alternative to traditional central heating systems. In this article, we will explore the pros and cons of using space heaters, how to calculate savings, tips for energy efficiency, and examples of real-life cost savings.

The Pros and Cons of Using Space Heaters to Save Money on Heating Bills

Pros of Using Space Heaters

One of the most significant benefits of space heaters is their potential to reduce energy costs. Here are several other advantages to consider:

Lower energy cost

Space heaters are known to be highly energy-efficient, which makes them an ideal solution for individuals or families who want to cut down on their heating expenses. Unlike central heating systems, which heat the entire home, space heaters direct the heat where it’s needed. It means you can save on energy bills by heating only the rooms you use, instead of the entire house.

They do not require installation costs

Another benefit of space heaters is that they do not require professional installation. Unlike central heating systems or other heating arrangements, space heaters are plug-and-play devices that require no installation costs, making them an affordable heating alternative.

Can heat a room quickly

The high heat output of space heaters, combined with their portability, allows them to heat up a room quickly, which is helpful if you have guests arriving on short notice or need to warm up a room before using it.

Cons of Using Space Heaters

While space heaters offer benefits in terms of energy efficiency and cost savings, they do come with some disadvantages:

Fire hazards

Space heaters run on electricity, and like any electrical device, there is a risk of fire hazards if they are not used properly. It is essential to keep them away from flammable materials, make sure they have proper ventilation and are always switched off when not in use.

Risk of carbon monoxide poisoning

Space heaters emit some carbon monoxide, which is dangerous at high concentrations. To avoid this risk, make sure that your space heater has a good ventilation system, and never leave it running overnight or in closed rooms.

Blow fuses

Space heaters draw a lot of power, and if they’re used on the same circuit as other high power-drawing devices, they can cause the circuit breaker to trip frequently, which could be an inconvenience.

How to Calculate the Savings of Using a Space Heater Compared to Central Heating

Basic Calculation for Electricity Usage

The calculation for energy usage of a space heater is straightforward. First, you need to find out the wattage of your space heater. Most space heaters come with a label indicating the wattage. Then refer to your electricity bill and find out your electricity rate. The formula for calculating how much energy your space heater uses is as follows:

Wattage x hours used x electricity rate = cost per day

For example, if you use a 1000-watt space heater for five hours a day, and your electricity rate is $0.12 per kilowatt-hour, the calculation would be: 1000 x 5 x 0.12 = $0.6

Comparison of Space Heating Versus Central Heating

Comparing the cost-effectiveness of space heaters to central heating depends on several factors, including the size of your home, your electricity rate, and the type of space heater you use. If you heat only the rooms that you’re using, space heaters usually prove to be more cost-effective than central heating systems. However, large, drafty homes with high heating needs may find central heating more efficient.

Tips to Maximize Energy Efficiency When Using a Space Heater for Savings

Keeping the temperature constant

Many space heaters come with adjustable thermostats, which can help control energy consumption and maintain a constant temperature. Set the thermostat at the lowest comfortable level to reduce energy consumption.

Ensuring proper placement

Effective use of space heaters will require proper placement. Keep the device away from flammable materials and adequate clearance to prevent potential fire hazards. Also, avoid placing them on the floor or carpet or near curtains. Place the space heater on a hard surface away from foot traffic to avoid risk and reduce contact with children and pets.

Monitoring usage

When using space heaters, keep an eye on their usage, especially when you’re not in the room. Don’t leave them on overnight or when you’re not at home – this will not only increase your energy consumption but also a risk to your safety.


Proper maintenance can ensure that a space heater remains energy-efficient, with maximum savings potential. Regularly adding oil to oil-filled space heaters, cleaning or changing air filters, and ensuring that the heating component is free of dust can help increase the lifespan of your space heater and improve its efficiency.

Comparing Different Types of Space Heaters and Their Cost-Effectiveness for Saving Money

Infrared heaters

Infrared heaters use radiation, which heats objects in the room without heating the air around them, making them energy-efficient. They are usually not suitable for large rooms or areas with drafts.

Ceramic heaters

Ceramic heaters use electricity to heat up a ceramic element, which then radiates heat throughout the room. They are affordable and effective in small to medium-sized rooms.

Oil-filled heaters

Oil-filled heaters use oil for heating and do not require electricity to operate, making them energy-efficient and affordable. They are safe, efficient, and suitable for larger rooms.

Comparing the Efficiency of Different Types of Heaters

The efficiency of space heaters depends on various factors, from the size of the room to the type of the heater. Oil-filled heaters are considered more energy-efficient than ceramic heaters due to their closed, seamless structure. Infrared heaters are energy-efficient but not practical in larger spaces. However, ceramic heaters are best suited for small to medium spaces and are affordable and easy to maintain.

Real-Life Examples: How People Have Successfully Saved Money Using Space Heaters Instead of Traditional Heating Methods

Personal accounts of saving money with space heaters

Many people have shared personal accounts of cost savings after switching to space heaters. One of them recounts using a space heater to heat only the room they spend most of their time in, letting them lower the overall thermostat by ten degrees, which resulted in a considerable cutback on their energy bill.

Examples of savings in different types of homes

Family A with a large drafty log cabin observed that switching to oil-filled heaters significantly reduced their heating bills. They were able to bring the monthly electricity bill down to $250 compared to over $400 during the winter months.

Family B with a small apartment replaced their old radiator with a ceramic heater. They saved 30% on their heating bill each month, which is a significant saving that added up over time.


Space heaters are definitely an effective way to save on heating bills, provided you use them wisely and responsibly. While there are some risks associated with space heaters, particularly with fire hazards, carbon monoxide poisoning, and tripping the circuit, these can be avoided with proper use and maintenance. With different types of space heaters available, you can likely find the one that makes the most sense for you and your home.

Before purchasing, read reviews, compare costs, and reexamine the elements of your home and requirements. Ultimately, with a little knowledge and some planning, you will be able to make an informed decision about whether space heaters are the right choice for you and your family.

Our advice: always remember to balance cost savings with safety and comfort.
