A contractor quoting a boiler installation in Clark County has to account for what this area puts systems through before they settle on equipment size or configuration. 132 severe weather events were recorded in Clark County, Indiana between 2015 and 2024. At that rate, severe weather is a standing condition here, and a boiler sized against catalog defaults rather than local load will run harder and recover more slowly than one spec'd for what the climate actually delivers. A contractor who treats sizing as a generic calculation will leave a homeowner with a system that meets code but not the house.
Ductwork and electrical service sized for an earlier generation of equipment are what a contractor walks into in much of Clark County. Half the homes in Clark County, Indiana were built in 1982 or earlier (2020-2024 ACS 5-year). That gap between what the house was built to carry and what a new boiler draws is where an installation job either stays straightforward or expands. A contractor will check what is already in the walls and ceilings before committing to a scope, because the existing runs may need modification to move air or water the way the new unit requires.
What a New Boiler Installation Covers
The boiler itself sits in a mechanical room, basement, or utility space and is the unit that heats water for the whole system. A contractor mounts it against a wall or floor depending on the model, then connects it to the gas line, the flue, and the supply and return piping that run through the house.
The radiators or hydronic baseboards are the pieces a homeowner sees in each room, and each one receives hot water from that piping and gives off heat to the space around it. An expansion tank, typically hung near the boiler, absorbs pressure changes in the water as it heats and cools, and a circulator pump keeps water moving through the loop.
The drawing here shows a representative layout, and a licensed contractor determines exactly what applies to this house and its existing setup.

Clark County's weather puts real demands on heating equipment over its working life. A boiler sized and installed for local conditions holds up better than one spec'd without that context.
