Homeowners in New York City often choose gas heating because it is typically more efficient and less expensive per unit of heat than electric systems. Natural gas furnaces, boilers, and water heaters deliver steady warmth and reliable performance during the colder months.
Yet, despite using a fuel that costs less than electricity, many households still experience significant increases in their overall energy bills during the winter. If gas is supposed to be cheaper, why do our gas bills tend to be more expensive?
Why Winter Energy Costs Rise
It’s not the gas, necessarily. It’s the usage. There are several factors that contribute to higher gas and energy bills during colder months, even when gas itself is the more economical energy source.
- Greater Temperature Difference – In the winter, heating systems must work much harder to maintain indoor comfort. A boiler may need to raise the indoor temperature from 40°F to 70°F, compared to an air conditioner that only needs to lower the temperature by about 10°F in the summer. That extended operating time increases fuel consumption.
- Increased Time Indoors – Colder weather keeps people inside, and that means more consistent heating use throughout the day and night. In addition, water use for showers, dishwashing, and laundry often rises in the winter, increasing the demand on your water heater and plumbing system.
- Heat Loss from Inefficient Fixtures – Older plumbing systems and fixtures can contribute to heat loss, especially if hot water lines are uninsulated or if the boiler and pipes are located in unheated basements. This wasted heat forces the system to work harder and use more gas to maintain water temperature.
- Tiered Gas Rate Structure – In New York City, utility providers such as Con Edison use a tiered rate structure for natural gas. The initial amount of gas you use is billed at a lower rate, while any usage above that threshold is charged at a higher rate. As your heating needs increase during the winter, the cost per unit of gas may also increase.
- Loss Through the Building Envelope – Drafty windows, uninsulated walls, and gaps around plumbing penetrations allow warm air to escape and cold air to enter. This increases both heating demand and overall energy use.
In some of these cases, you may need to hire a contractor to improve the energy efficiency of your home. But in most situations, the issue is not the gas – it is the way that homeowners have to use their system to keep their home warm.
Signs of Energy Inefficiency in Your Heating and Plumbing Systems
If your gas bills seem unusually high, the cause may go beyond seasonal usage. Common plumbing-related factors include:
- Aging or inefficient boilers and water heaters
- Leaking valves or poorly insulated hot water pipes
- Improperly sized or poorly maintained heating systems
- Air trapped in radiators or hydronic lines, reducing heat transfer
- Lack of thermostatic controls or zoning
A licensed master plumber can evaluate these systems, identify where energy is being lost, and recommend targeted improvements.
How to Improve Efficiency and Comfort
Improving your building’s efficiency doesn’t necessarily mean replacing major systems right away. Simple upgrades can make a noticeable difference:
- Insulating exposed hot water pipes to retain heat longer
- Flushing boilers and checking circulation for optimal performance
- Installing programmable thermostats or zoning valves to reduce unnecessary heating
- Replacing outdated fixtures with modern, water-saving, and energy-efficient alternatives
- Addressing air leaks around plumbing openings, vents, and chases
When plumbing and heating systems work efficiently, they maintain warmth more effectively, reduce waste, and help stabilize monthly gas bills even during peak winter demand.
