Heating your home is an important consideration, and choosing the right type of heater can have a significant impact on your comfort level and energy bills. Two of the most common types of heating systems are electric and gas heaters. While both types of heaters have their pros and cons, understanding their differences can help you make an informed decision about which one is right for your home.
In this blog post, we’ll take a closer look at electric heaters and gas heaters, as well as their advantages and disadvantages. We’ll also compare the two types of heaters based on factors such as energy efficiency, operating cost, safety features, and more.

Electric Heaters

Electric heaters work by converting electricity into heat. They are available in various types, including convection heaters, storage heaters, and heat pumps. Let’s take a closer look at the advantages and disadvantages of electric heaters.
Advantages of Electric Heaters
- Safety: Electric heaters do not produce any flames or emit any harmful fumes, making them a safe option for households with young children or pets. They also do not require any combustible fuel, reducing the risk of gas leaks or explosions.
- Cost-effectiveness: Electric heaters are generally less expensive to purchase and install compared to gas heaters. They also require less maintenance, as there are no moving parts that can wear out or break down.
- No risk of gas leaks: As mentioned earlier, electric heaters do not require any combustible fuel, meaning there is no risk of gas leaks or carbon monoxide poisoning.
Disadvantages of Electric Heaters
- Higher operating cost: Electric heaters have a higher operating cost compared to gas heaters, as electricity is generally more expensive than natural gas.
- Slower to heat up: Electric heaters can take longer to heat up a room or space, especially larger areas. This means that they may not be as effective in colder climates or during periods of extreme cold.
Types of Electric Heaters
- Convection heaters: These heaters work by heating up the air around them and circulating it throughout the room.
- Storage heaters: These heaters use an insulated tank to store heat during off-peak hours, and release it as needed throughout the day.
- Heat pumps: These heaters use electricity to extract heat from the air or ground outside and transfer it inside the house.
Gas Heaters

Gas heaters, on the other hand, use natural gas or propane to produce heat. They are available in various types, including instantaneous gas heaters, gas furnaces, and gas water heaters. Let’s take a closer look at the advantages and disadvantages of gas heaters.
Advantages of Gas Heaters
- More energy-efficient: Gas heaters are generally more energy-efficient compared to electric heaters, meaning they use less energy to produce the same amount of heat.
- Lower operating cost: Natural gas is generally less expensive than electricity, meaning that gas heaters have a lower operating cost compared to electric heaters.
- Faster to heat up: Gas heaters can heat up a room or space faster compared to electric heaters, making them a good option for colder climates or during periods of extreme cold.
Disadvantages of Gas Heaters
- Risk of gas leaks and carbon monoxide poisoning: Gas heaters produce flames and emit fumes, meaning that there is a risk of gas leaks or carbon monoxide poisoning if they are not installed or maintained properly.
- Higher installation cost: Gas heaters generally have a higher installation cost compared to electric heaters, as they require a gas line and a separate heating appliance.
Types of Gas Heaters
- Instantaneous gas heaters: These heaters heat up water on demand, providing a continuous supply of hot water.
- Gas furnaces: These heaters use natural gas to heat air, which is then distributed throughout the house through a duct system.
- Gas water heaters: These heaters use natural gas or propane to heat up a tank of water, which is then stored and supplied as needed.
Gas Heater vs Electric Heater
Now that we’ve taken a closer look at electric heat, and gas heaters, let’s compare the two based on various factors.
- Energy efficiency: As mentioned earlier, gas heaters are generally more energy-efficient compared to electric heaters, meaning they use less energy to produce the same amount of heat.
- Operating cost: Natural gas is generally less expensive than electricity, meaning that gas heaters have a lower operating cost compared to electric heaters.
- Safety features: Electric heaters are generally safer compared to gas heaters, as they do not produce any flames or emit any harmful fumes. Gas heaters, on the other hand, have a risk of gas leaks or carbon monoxide poisoning if they are not installed or maintained properly.
- Installation cost: Gas heaters generally have a higher installation cost compared to electric heaters, as they require a gas line and a separate heating appliance.
- Heating capacity: Gas heaters can heat up a room or space faster compared to electric heaters, making them a good option for colder climates or during periods of extreme cold.
- Maintenance: Electric heaters generally require less maintenance compared to gas heaters, as there are no moving parts that can wear out or break down.
- Availability: Electric heaters are generally more widely available compared to gas heaters, especially in areas where natural gas is not available.
Which One is Right for You?
Choosing between an electric heater and a gas heater ultimately depends on your specific needs and circumstances. If you prioritize safety, cost-effectiveness, and ease of installation, an electric heater may be the right choice for you. On the other hand, if you prioritize energy efficiency, faster heating, and lower operating costs, a gas heater may be the better option.
Regardless of which type of water heater you choose, it’s important to ensure that it is installed and maintained properly to ensure optimal performance and safety. If you’re unsure about which type of heater is right for your home, consult with a professional heating contractor for expert advice and recommendations.
