When Bergen County winters arrive, having a reliable heating system is not optional. But if you're building a new home, replacing an aging system, or just trying to understand what you have, it helps to know the difference between the two most common heating systems: boilers and furnaces. Both will keep your home warm, but they work differently, have different maintenance needs, and suit different types of homes.
How a Furnace Works
A furnace heats air and distributes it through your home via a network of ducts and vents. When your thermostat calls for heat, the furnace burns fuel (typically natural gas, propane, or oil) to heat a metal heat exchanger, and a blower fan pushes warm air through the ducts. Furnaces are common in newer homes built with central air, since the same duct system can handle both heating and cooling.
Advantages of a Furnace
- Heats your home quickly—warm air reaches rooms fast.
- Compatible with central air conditioning using the same duct system.
- Generally lower upfront installation cost than a boiler.
- Wide range of high-efficiency models (up to 98% AFUE).
Disadvantages of a Furnace
- Forced air can feel dry and may circulate allergens or dust.
- Ductwork requires regular cleaning and can leak, reducing efficiency.
- Uneven heating is more common than with radiant heat.
How a Boiler Works
A boiler heats water—or produces steam—and distributes that heat through radiators, baseboard heaters, or radiant floor tubing. Hot water boilers (hydronic systems) are the most common type in New Jersey homes. Many older Bergen County homes have cast-iron radiators connected to original boiler systems, some of which are still performing admirably decades later.
Advantages of a Boiler
- Provides consistent, even heat—radiant warmth feels more comfortable than blown air.
- No ductwork means no duct cleaning and no allergen distribution.
- Hot water systems are very durable—a well-maintained boiler can last 20–30 years.
- Radiant floor heating is exceptionally comfortable and efficient.
Disadvantages of a Boiler
- Higher upfront cost than a furnace.
- Cannot be used for central air conditioning—you'll need a separate cooling system.
- Slower to respond to thermostat changes than a furnace.
- Risk of frozen pipes in rarely used areas if the system shuts down in winter.
Which Is More Common in North Jersey?
Bergen County and Hudson County have a lot of older housing stock—many homes built from the 1920s through the 1960s were originally heated with boilers and cast-iron radiators. If your home has radiators, you almost certainly have a boiler. Newer homes built after the 1980s tend to have forced-air furnaces with central air.
Which Should You Choose?
The right system depends on your home. If you already have ductwork and want the ability to add central AC, a high-efficiency furnace is a great choice. If you value the even, comfortable warmth of radiant heat and don't mind separate cooling, upgrading your boiler makes sense—especially if you already have radiators.
