A long winter here
Boilers in Chester run from October through April, and overnight lows average 27°F in January. That's a lot of hours on the burner and the pump over the course of a winter.

Step 1 of 3: Equipment
Usual wear, not unusual strain
A boiler that's been through enough winters here will eventually show a weak igniter, a failing circulator pump, or a pressure problem. Finding which one it is matters more than how old the system is or how hard last winter was.
Boilers in Chester start their first cold run in October.
A circulator pump or igniter that limped through last April can fail the moment it's asked to run again.

Scale buildup strains the heat exchanger
Water sitting in a boiler leaves mineral scale behind as it heats and cools, and that scale coats the heat exchanger over time. A coated exchanger has to push harder to move heat into the water, and that strain is what eventually cracks it or burns out a nearby component.
The circulator pump and igniter wear out first
Both parts work every time the boiler fires, so they fail before most other components do. A circulator pump that's seized or losing strength means heat isn't moving through the system even though the burner runs fine. A failing igniter means the burner won't light at all, or it lights and then drops out.
A boiler that's making a bad noise or short cycling will keep doing the job, which is exactly the problem. A circulator pump that's starting to seize still turns, just slower, and it'll keep pushing water until it locks up completely and stops moving heat altogether. A cracked heat exchanger will keep heating water while it leaks, and running it longer doesn't seal the crack, it just lets more water find its way out. Low pressure that goes ignored lets the boiler keep firing dry in spots, which is how a heat exchanger gets damaged in the first place. None of these get better on their own. The boiler doesn't know it's hurt, it just keeps running until something stops it.
A boiler that's old but sound is usually worth fixing. A boiler that's young but cracked usually isn't. So the question isn't how many winters it's seen, it's what actually broke. An igniter, a thermocouple, a circulator pump, a pressure switch. These are wear parts, and swapping one out is a routine repair no matter how long the boiler has been running. A cracked heat exchanger or a corroded water jacket is a different kind of problem. That's the core of the boiler failing, not a part bolted onto it, and it usually isn't meant to be replaced on its own. Ask what failed before asking how old the system is. That's what tells you whether it's worth fixing.
