Sizing a boiler for a house in Dillon County starts with knowing how much real work it will actually do. Homes in Dillon County, SC run heat about five months a year, from November through March. The burner and heat exchanger cycle on and off through every one of those months, and the stress that accumulates on those components is a direct product of that cycling, not of anything else. A unit that a contractor installs without a proper load calculation for this house runs either too hard or too short, and either way the ignition system and the heat exchanger pay for it ahead of schedule.
Ductwork laid for an earlier generation of equipment does not always match what a modern boiler needs to move heat through a house. A contractor here has to establish whether what is already in the walls will carry the new system before any other number on a quote means anything. Half the homes in Dillon County, South Carolina were built in 1984 or earlier (2020-2024 ACS 5-year). That puts the existing duct configuration at the center of an installation assessment in this county, and a homeowner pricing a new boiler is really pricing the ductwork first.
What a Boiler Installation Covers
The boiler itself sits in the basement or utility room and is the unit that heats water and sends it out through the home. A contractor mounts it against a wall and connects it to the fuel supply, the flue, and the piping that feeds the rest of the system. That unit is the core of everything a new installation sets in place.
From the boiler, copper or PEX piping runs through the house to the radiators or radiant panels that sit in each room or beneath the floor. A circulator pump, mounted close to the boiler, moves the heated water through those pipes. An expansion tank and pressure relief valve sit nearby as well, each serving a protective role in keeping the system at safe operating pressure.
The drawing shows a typical layout, and a licensed contractor determines exactly what the installation requires in this house.

Severe Weather Events in Dillon County
Weather puts real stress on heating equipment, and how hard a boiler works over its life is shaped by the local climate more than any spec sheet. What happens in Dillon County with storms and temperature swings is the load a contractor installs for.
