What’s the real cost of switching from LPG to city gas? Is it worth upgrading your gas range for better compatibility? Let’s dive into the world of city gas and LPG to understand how this choice can affect your household budget and daily convenience.
City gas LPG conversion
Switching from LPG (liquefied petroleum gas) to city gas is becoming more common as urban infrastructure improves. But how exactly does this conversion work, and what should homeowners be aware of?
Understanding the conversion process
When you convert your household from LPG to city gas (usually LNG, liquefied natural gas), the process involves:
-
Replacing or adjusting appliances like gas stoves, boilers, or water heaters to be compatible with city gas.
-
Installing new piping systems that meet municipal gas line standards.
-
Working with licensed professionals—conversion must be done by certified technicians under strict safety regulations.
This isn’t just a plug-and-play operation. LPG burns differently than city gas, which has a lower calorific value. Therefore, the gas injectors and burners must be recalibrated or replaced to handle the different pressure and combustion requirements.
Real-world experience: My own conversion
In my own apartment in Mapo-gu, the conversion process took two days. The technician checked all equipment, changed nozzles on my stove, and coordinated with Samchully (a major city gas provider in Korea) for final inspection. The cost? Around ₩350,000, including labor and materials—but the long-term savings have more than made up for it.
Common concerns during conversion
-
Downtime Most conversions can be completed within 24–48 hours, but you’ll be without gas during this time.
-
Hidden costs Some homeowners discover they need to replace older appliances, especially if they can’t be safely converted.
-
Safety checks Expect multiple inspections before and after the conversion.

City gas LPG fee
Many people believe city gas is always cheaper—but is that really true?
Basic fee structure differences
-
LPG is often sold in cylinders or measured in kg, with delivery fees and bottle rentals included.
-
City gas, on the other hand, is metered and charged monthly based on usage in cubic meters (㎥), with a standing basic fee.
| Category | LPG (Avg. per kg) | City Gas (Avg. per ㎥) |
|---|---|---|
| Residential Use | ₩2,200–2,600 | ₩800–1,000 |
| Heating Use | ₩2,000–2,400 | ₩700–900 |
From this, it’s easy to see city gas is almost 2.5x cheaper per energy unit, especially when used in larger volumes like winter heating.
Case study: A monthly gas bill comparison
When I lived in a one-room studio using LPG, my winter gas bill could reach ₩120,000. After converting to city gas in my new apartment, even with heavier heating, my bills dropped to around ₩55,000—a savings of over 50%.
Fee-related considerations
-
Metering transparency City gas offers better usage tracking, while LPG relies on estimates or irregular bottle changes.
-
Subsidies and discounts Some city gas providers offer low-income family discounts, unavailable for LPG users.
-
Variable pricing LPG prices can fluctuate more sharply due to delivery costs and international oil markets.

Gas Range City Gas LPG
One often-overlooked part of switching gas types is your kitchen appliance the gas range. But using the wrong type can be both dangerous and inefficient.
Compatibility differences
City gas and LPG require different gas pressures and nozzle sizes
-
LPG ranges are built for higher pressure and tighter orifices.
-
City gas ranges have broader nozzles and burn at lower pressures.
If you use an LPG range with city gas, it may not ignite properly or burn inefficiently, leading to soot buildup and carbon monoxide risks.
How to check your gas range type
Look for a metal plate or sticker on the back or underside of your range. It should specify:
-
Type: LPG / LNG (city gas)
-
Rated pressure
-
Nozzle size
Some modern models are dual-compatible, allowing for nozzle change kits. However, older models might require complete replacement.
My own upgrade: From LPG to city gas range
After switching to city gas, I initially tried using my old LPG range. The flames were weak and unstable. I upgraded to a city gas-compatible gas range (₩180,000), which immediately improved heat control and cooking performance.
Safety and energy efficiency tips
-
Install a gas leak detector for peace of mind.
-
Annual maintenance checks are crucial—especially if you’ve converted appliances.
-
Use proper cookware Flat-bottomed pots improve energy transfer, saving both gas and time.

Conclusion
Choosing between LPG and city gas isn’t just about price—it affects your safety, convenience, and long-term energy efficiency. As the quote goes, “The best investment is in the tools of one’s own trade.” Whether it’s upgrading your gas range, reducing your monthly bills, or ensuring safer living conditions, understanding city gas vs. LPG gives you the power to make smarter home energy decisions.
