When choosing a new heating system for your Denver, CO home, you have the option of gas or electricity as the fuel source. There are pros and cons to both, and we’ll explain them in detail so you can make an educated choice. Rely on our team at Summit Heating, A/C, Plumbing & Electrical if you have any questions during the decision-making process.
Understanding the Denver Climate
Denver has very snowy winters, with dramatic temperature swings and dry air. It’s important that you select the right heating system so you can efficiently keep your residence comfortable. Both gas and electric heating can keep you warm during the coldest months of December, January, and February. However, one option may be more efficient than the other when it comes to initial cost, performance, and ongoing maintenance.
Denver has an altitude of approximately 5,280 feet, which can impact air density and heating efficiency. Winter temperatures can drop into the low 20s (Fahrenheit). It’s necessary to achieve quick heat, especially during cold snaps.
The Basics of Gas and Electric Heating
Gas heating systems use propane or natural gas to generate heat through the process of combustion. This is what boilers, gas furnaces, and even radiant floor heating systems use.
Electric heating converts electrical energy into heat using heat pump technology or resistance. This is used by baseboard heaters, electric furnaces, heat pumps, and ductless mini-split systems.
Comparing the Cost of Gas Versus Electric
The cost of installing an electric heating system is usually more affordable than a gas variety. This is especially true when the work is being completed in a home that doesn’t have gas lines in place.
If you have gas lines in place, it can be wise to use them. Natural gas is usually more affordable than electricity in the Denver area. In 2025, the cost of gas was approximately $1.10 per therm. Electricity averaged between $0.13 and $0.15 per kWh. You can expect to save 30% to 50% when you use a gas heating system compared to an electric one.
The Benefits of Gas Heating
In addition to pricing, gas heating is also very fast and powerful. If the temperature drops quickly, your heating system will be able to keep up easily. Gas heating is also reliable when the power goes out in your home.
A gas furnace has a life expectancy of 15 to 20 years with regular upkeep. This is roughly the same amount of time compared to an electric heating system. However, you may be able to use your gas furnace for a few extra years.
The Benefits of Electric Heating
Electricity has a nearly 100% conversion efficiency rating for heating purposes. This is a very environmentally friendly form of heating, especially if you’re using something like solar panels to generate electricity. This is a safer heating option for your home, too, as it avoids combustion and doesn’t produce carbon monoxide.
If you’re considering using a zoning system in your residence, electricity works well for this purpose. There is a lot of flexibility involved with installing an electric heating system.
Things to Keep in Mind in a Cold Climate
When temperatures drop very low outside, older electric heating systems can struggle. However, there are modern units and cold-climate heat pumps that do a very good job. You can expect a gas heating system to function consistently, even when temperatures are very low.
Gas Heating Safety Considerations
A gas heating system will produce carbon dioxide and nitrogen oxides. You need to ensure your system is running safely by scheduling routine maintenance regularly. You should also maintain carbon monoxide and smoke detectors in your home. Ensure proper ventilation so there is a healthy exchange of air between the inside of your home and the outdoors.
Maintenance and Life Expectancy
You should schedule an annual maintenance and inspection for your heating system, regardless of whether it uses gas or electricity. The inspection process for a gas system includes additional safety considerations. Electric systems are more straightforward. You won’t typically see a difference in cost for routine maintenance.
What Homes Benefit From Gas Heating?
Gas heating is a better option if your home is already set up with gas lines. If you live in a very large home and want to ensure consistent comfort throughout, gas may be the better option. It’s also a better option if budget is a concern and you wish to prioritize low operating costs. Lastly, if you live somewhere that experiences frequent power outages and you don’t have a backup generator, gas is ideal.
What Homes Benefit From Electric Heating?
If you don’t have gas access and you don’t want to outfit your home with gas lines, it’s better to stick with electric heating. This is also an ideal option for small homes or homes with a zoning system in place. If you’re environmentally conscious, electricity is the way to go.
More Smart Heating Options
To complement your gas or electric heating system, there are modern and smart devices and systems to consider. For example, a smart thermostat will work with whichever option for power you choose. You can use this device to receive maintenance alerts, monitor your usage, and schedule temperature adjustments.
If you’re looking for more flexibility than gas or electric can provide alone, consider a dual-fuel system when replacing your current heating setup. This combines electricity and gas heating for better efficiency. Typically, this is a combination of a heat pump and a gas furnace. The heat pump handles mild winter conditions, while the furnace will turn on when it’s extremely cold.
Consider having a home energy audit scheduled to learn more about how your home uses energy. This is an important process that can help you cut back on energy consumption and lower your monthly bills.
Considering Rebates and Incentives
In the Denver area, there are several ways you can save on the investment of a gas or electric furnace. Xcel Energy provides rebates for homeowners who purchase high-efficiency furnaces or heat pumps. The Colorado Energy Office offers discounts to support renewable energy upgrades. There are also federal tax credits available for ENERGY STAR-rated systems.
In the Denver area, we see many homeowners invest in a gas-powered heating system. This is a reliable option that ensures you achieve exceptional comfort throughout the entire winter. However, there’s no denying that electric heating is safe, sustainable, and flexible.
