Sizing a boiler correctly for this house matters more than it might seem at first. Homes in Lauderdale County, MS run heat about five months a year, from November through March. The burner and heat exchanger cycle through that whole stretch, and a unit that was undersized at installation runs harder and longer than it was built to. A contractor quoting a replacement here will establish the heat load of the house before specifying equipment, because a boiler that is right for the load wears at the rate it was designed for.
Ductwork laid down for one kind of system and then handed through successive owners to another is what a contractor sizing a boiler replacement actually has to work with here. Half the homes in Lauderdale County, Mississippi were built in 1979 or earlier (2020-2024 ACS 5-year). That matters for installation because the runs, connections, and returns in a house of that vintage were not planned around what a modern boiler asks of them. A contractor who finds the existing ductwork undersized for the new unit's distribution requirements has to price that correction into the job before the equipment itself becomes the focus.
What a Boiler Installation Covers
The boiler itself sits in a mechanical room, basement, or utility closet and is the unit that heats water for the whole system. The circulator pump mounts directly to the boiler or nearby pipework and moves that heated water through the house. The expansion tank, also close to the boiler, absorbs pressure changes as the water heats and cools.
Radiators, baseboard units, or radiant floor loops are the delivery points where heat actually enters each room. The thermostat goes on an interior wall and tells the system when to fire. Shutoff valves, fill valves, and a pressure relief valve are fitted at the boiler to give a contractor control over the water supply and system pressure.
The drawing shows a typical boiler layout, and a licensed contractor determines exactly what applies to your home.

Severe Weather Events in Lauderdale County
Boiler systems take on a heavier load when the local climate runs to weather extremes, and equipment sized and installed for that reality lasts differently than equipment that ignores it. Lauderdale County's conditions make this a local question, which is why contractors here account for it.
