Introduction: Why More Connecticut Homeowners Are Converting from Oil to Gas
For decades, Connecticut homes have relied on oil furnaces and boilers to keep warm during the state’s long, snowy winters. While oil heating systems have been the norm, rising fuel costs, environmental concerns, and the availability of natural gas have led many homeowners to consider switching.
That’s where oil-to-gas conversion comes in. This process replaces an existing oil-fired heating system with a natural gas system, offering homeowners cleaner energy, greater efficiency, and long-term cost savings.
At Energy Unlimited, we’ve helped countless Connecticut families make this transition. In this guide, we’ll walk you through the benefits, the process, the costs, and the incentives available for oil-to-gas conversion—so you can decide if it’s the right step for your home.
Why Consider Oil-to-Gas Conversion?
Cost Savings Over Time
Heating oil prices have been historically volatile, rising significantly during winter months when demand is highest. By contrast, natural gas tends to be more stable and affordable.
-
Average fuel costs: On average, natural gas costs 30–40% less than heating oil in Connecticut.
-
Efficiency gains: New gas furnaces and boilers often operate at 90–98% efficiency, compared to older oil systems that may only run at 60–70%.
Over a decade, these savings can add up to thousands of dollars.
Cleaner and Greener Energy
Natural gas is one of the cleanest-burning fossil fuels. Compared to oil, it produces:
-
30% less carbon dioxide emissions
-
80% less sulfur dioxide and nitrogen oxides, which contribute to smog and acid rain
-
No soot or ash buildup in the heating system
By converting, you’re not only improving your home’s comfort but also helping reduce your household’s carbon footprint.
Convenience and Reliability
Oil systems require homeowners to monitor fuel levels and schedule deliveries. Running out of oil in the middle of a cold snap is inconvenient—and potentially dangerous.
With natural gas:
-
You’ll have a continuous, reliable fuel supply via underground pipelines.
-
There’s no need for bulky storage tanks.
-
Maintenance is easier because gas burns cleaner, leaving fewer residues in the furnace or boiler.
Increased Home Value
Buyers often view natural gas heating as a desirable feature due to its efficiency and lower operating costs. Converting to gas can make your home more appealing on the market.
The Oil-to-Gas Conversion Process
If you’re considering making the switch, here’s what to expect when working with Energy Unlimited:
Initial Consultation and Home Assessment
We begin with a comprehensive evaluation of your current heating system, fuel usage, and home layout. We’ll also confirm whether natural gas service is available in your area—most Connecticut communities have expanding access.
Equipment Recommendations
Based on your home’s size and heating needs, we’ll recommend the right high-efficiency gas furnace, boiler, or heat pump hybrid system. Our goal is to size the system properly—too small and it won’t keep up in the cold, too large and you’ll waste energy.
Permits and Approvals
Converting to gas requires local permits and safety inspections. Our team handles the paperwork and coordinates with your town and the utility provider to ensure a smooth transition.
Tank Removal (if applicable)
If you have an old oil tank, we’ll arrange for its safe removal. Above-ground tanks are typically easier to dispose of, while underground tanks may require environmental testing.
Installation of Gas Lines and New Equipment
We’ll install the necessary gas piping, connect your home to the utility line, and set up your new furnace or boiler. Our technicians ensure everything meets Connecticut safety and efficiency codes.
System Startup and Final Testing
Once installed, we’ll run your system, calibrate it for peak performance, and walk you through the operation and maintenance steps.
Ongoing Maintenance and Support
Energy Unlimited offers maintenance agreements to keep your new gas system running at top efficiency year after year.
Costs of Oil-to-Gas Conversion in Connecticut
The cost of converting depends on several factors:
-
Proximity to the gas line: Homes located close to an existing gas main pay significantly less than homes that need extended piping.
-
Type of system installed: Furnaces and boilers vary in price, with high-efficiency units costing more upfront but saving more in the long run.
-
Tank removal: Removing an old oil tank can add anywhere from $1,000 to $3,000 depending on complexity.
On average, Connecticut homeowners can expect an oil-to-gas conversion to cost between $6,000 and $12,000, depending on the scope of the project.
While this may seem like a big investment, most families find that the long-term fuel savings, combined with rebates and incentives, make the conversion worthwhile.
Common Questions About Oil-to-Gas Conversion
How long does the conversion process take?
Most conversions take 3–5 days once permits and utility connections are secured.
What happens to my old oil tank?
We’ll coordinate safe removal and disposal. If the tank is underground, environmental testing may be required to ensure no soil contamination.
Is natural gas really safer than oil?
Yes—while no fuel source is risk-free, natural gas systems have modern safety features, and you won’t need to worry about leaks, spills, or fuel deliveries.
Can I convert if my neighborhood doesn’t have a gas line?
In some cases, yes. Extensions may be possible, but costs increase. If natural gas isn’t available, we may recommend a high-efficiency propane system or ductless heat pump as an alternative.
Maintenance Tips for Your New Gas System
After converting, routine maintenance is key to keeping your system efficient:
-
Change filters every 1–3 months
-
Schedule annual professional tune-ups
-
Keep vents and registers clear of dust and obstructions
-
Install a carbon monoxide detector as an added safety precaution
