Sizing a boiler for this house means accounting for a long, unbroken demand on the burner, the heat exchanger, and the ignition system. Homes in Monmouth County, NJ run heat about seven months a year, from October through April. A contractor quoting a replacement here has to get the load calculation right before anything else, because a unit that runs undersized through a season this length cycles harder and more often than the equipment was rated to handle. The burner and heat exchanger carry that strain directly. A sloppy install does not stay hidden long.
Ductwork laid down for an earlier generation of heating does not automatically carry a modern boiler's distribution demands. A contractor pricing a new installation has to trace what is actually in the walls and determine whether it can do the job asked of it now, before the equipment selection means anything. Half the homes in Monmouth County, New Jersey were built in 1975 or earlier (2020-2024 ACS 5-year). That history is why the duct assessment comes first and the unit spec comes after.
What Gets Installed With a New Boiler
The boiler itself sits in a mechanical room, basement, or utility closet and is the unit that heats the water. From there, supply pipes carry hot water to radiators, baseboard units, or radiant floor loops throughout the house, each of which releases heat into the room where it stands.
An expansion tank, typically mounted near the boiler, absorbs pressure changes as water heats and cools. A circulator pump moves the water through the loop, and a zone valve or thermostat controls which areas of the house call for heat and when.
The drawing shows a representative layout, and a licensed contractor determines exactly which components apply to your home.

Severe Weather Events in Monmouth County
