How Long Does a Boiler Last in New York?
April 14, 2020
On average, boilers usually last about 15-30 years.
However, the exact length of your boiler’s life depends on a variety of factors, like:
The type of boiler you have
Whether or not the boiler was installed properly
How often you’ve maintained your boiler
In this article, we’ll go into more detail about each of these factors and how they can impact the lifespan of your boiler in New York.

Factor #1: The type of boiler you have
Hot Water vs. Steam Boiler
In the NYC area, homeowners typically either have a hot water (hydronic) or a steam boiler.
Usually, water/hydronic boilers have a greater lifespan compared to steam boilers:
The average lifespan of a water/hydronic boiler: 30+ years
The average lifespan of a cast iron steam boilers: 20-25+ years
The average lifespan of a high-efficiency condensing hydronic boiler: 15-20 years
Steam boilers typically have a shorter lifespan because they have a greater tendency to develop leaks. Leaks that occur from components such as piping, valves and radiators quite often go unnoticed. The result is excess wear and tear on the boiler due to a constant loss of steam and the introduction of replacement water into the system. This contributes to a shortening of the boiler’s lifespan.
High Efficiency vs. Standard Efficiency Boiler
Keep in mind that if you have a gas boiler at home, its lifespan will vary depending on whether it’s a condensing/high efficiency boiler or non-condensing boiler.
While condensing boilers are more efficient than non-condensing boilers, condensing boilers have a slightly shorter lifespan than non-condensing boilers.
Condensing boilers are constructed to hold onto flue gases longer to capture more heat; however, these flue gases are extremely acidic, which can cause a boiler’s components to wear out sooner, curbing its lifespan.
Factor #2: Whether your boiler was installed properly
It’s estimated that over 85% of boilers in the U.S. are sized improperly. So what does this mean for you? Well, if your boiler is improperly sized for your home, it won’t last as long as it’s designed to.
If your boiler is too big, it will heat your home quickly and then shut off. This constant ON and OFF pattern can wear out the motors and other integral parts in the boiler.
If your boiler is too small, it will run continuously. This round-the-clock action puts unnecessary strain on a boiler’s motor and other important components.
So, how should your boiler be sized?
Boilers are sized according to the amount of heat they put off per hour (measured in BTUs). The higher the BTU output (more heat a boiler creates per hour), the “larger” the boiler is.
When your boiler was initially installed, a “radiator survey” or a “heat loss calculation” should have been performed in order to properly determine the size of boiler your home needs. This test entails looking at various factors like the square footage of your home, the number of windows and doors, the amount and quality of insulation, etc. However, if a proper test wasn’t performed, you could easily have a system that’s too big or small.
Here’s how to determine whether your boiler is oversized or undersized:
Signs your boiler is oversized:
Boiler short cycles (turns on then quickly turns off)
Frequent leaks in the boiler system
Hot and cold spots throughout the home
Signs your boiler is undersized:
Home never gets to desired temperatures on particularly cold days
Boiler runs non-stop on cold days
Factor #3: How often your boiler has been maintained
At the least, you should have your boiler maintained annually. If you’re not servicing your boiler at least once every year, you’re probably spending more than you should on fuel costs and potentially taking years off your boiler’s life.
According to Energy Star, regular maintenance will help you avoid problems and repairs that could cause a premature system failure in the future.
When a quality professional performs boiler maintenance, they should:
Check the gas connections for proper operation and pressure
Check and clean the burner combustion
Lubricate all moving parts (for decreased energy usage)
Tighten all electrical connections
Check controls for proper and efficient operation
Check chimney draft
Checking these kinds of components will prevent your boiler from running inefficiently or incorrectly, which can help you avoid large issues and extend the life of your system.
