Takes about a minute. No obligation.
A boiler being quoted for Orange County has to be sized and installed to carry a full, long workload without shortcuts. Homes in Orange County, VT run heat about nine months a year, from September through May. The burner fires and the heat exchanger expands and contracts through all of that, and a unit that leaves the job undersized or with a poorly seated combustion assembly will show stress fractures and ignition faults well before a better-installed system would. Contractors sizing a replacement here treat flue sealing and expansion clearances as load-bearing decisions, not finishing details.
Ductwork and distribution built for equipment that has long since been pulled out defines what a contractor is actually working inside on a boiler job here. Half the homes in Orange County, Vermont were built in 1978 or earlier (2020-2024 ACS 5-year). That age of housing stock tends to have distribution runs configured around whatever heated the house originally, and a new boiler has to connect to what is there. If the existing layout carries the new unit's output to every room, the install moves cleanly. If it does not, re-routing is the job before the job, and that is what shapes the quote.
What a Boiler Installation Puts in Your Home
The boiler itself sits in the basement or mechanical room and is the unit a contractor replaces or sets in place when the system is new. Paired with it is the expansion tank, which mounts nearby and absorbs pressure shifts in the water as it heats.
Radiators or baseboard convectors occupy the living spaces, each one connected to the boiler by supply and return pipes that run through the walls and floors. A circulator pump, mounted at the boiler, moves the heated water through those pipes and back again.
The drawing beside this text shows a typical layout, and a licensed contractor determines which components and configurations apply to your specific home.

Licensing and Legal Requirements in Orange County, Vermont
Vermont splits the trade across two specialty licences and a contractor may hold one without the other: field A1 covers automatic gas or oil heating including geo-thermal and ground source heat pumps, and field C3 covers refrigeration or air conditioning including air-to-air heat pumps.
Vermont reaches HVAC work through its electricians’ licence rather than an HVAC licence, and the requirement stops at the front door of a house: anyone performing electrical work in Vermont must be licensed as an electrician unless the work is in a residential building containing two or fewer dwelling units.
