Sizing a boiler for this house starts with knowing how long the burner actually runs. Homes in Orange County, NY run heat about eight months a year, from October through May. A burner that cycles through that span accumulates wear on the ignition system, the heat exchanger, and the controls that a shorter season would leave largely untouched. A contractor quoting a replacement here factors that load into both the equipment specification and the quality of the installation, because a unit that is marginal at the start of the season will not improve as the months pass.
Ductwork in a house this old was laid out for whatever the builder put in originally, and a boiler installation contractor prices the distribution system before the unit itself. Half the homes in Orange County, New York were built in 1975 or earlier (2020-2024 ACS 5-year). Pipes, zones, and radiator loops that predate current equipment may feed a new boiler poorly if they were never configured for it, which is why a contractor opens the mechanical room and traces the existing layout before quoting anything else.
What a Boiler Installation Covers
The boiler itself sits in the basement or a mechanical room and is the heart of the installation. A contractor sets it in place, connects it to the fuel supply, and ties it into the home's existing piping. The expansion tank mounts nearby and keeps pressure in the system stable.
The circulator pump attaches directly to the boiler and moves heated water through the pipes to each zone. Thermostats go on the walls of each zone and tell the system when to call for heat. Zone valves or a manifold, depending on how the house is piped, sit along the supply lines and direct flow to the right rooms.
The drawing beside this text shows a typical layout, and a licensed contractor determines what applies to your specific house.

Boiler systems work hardest when outdoor conditions are at their worst. How often that happens in Orange County shapes what a system needs to handle over its lifetime, which is why local weather history is part of the picture when sizing and installing equipment here.
