Sizing a boiler for a Kane County home is not a spec-sheet exercise. 298 severe weather events were recorded in Kane County, Illinois between 2015 and 2024. At that rate, severe weather is part of the baseline a contractor prices against, not an edge case. A system that is under-built for this area will run harder and cycle more than one installed with the local load in mind, and the difference shows up in early heat exchanger wear and pressure relief failures. A contractor quoting installation here sets the capacity and the installation standard around weather that arrives regularly, because the cost of getting that wrong falls on the equipment first.
Ductwork laid down for equipment sold generations ago was not engineered for what a modern boiler installation asks of it. Half the homes in Kane County, Illinois were built in 1985 or earlier (2020-2024 ACS 5-year). A contractor quoting a new boiler here has to assess whether those existing runs can carry the new system's output, and in much of this county's housing stock the answer changes the scope and the price before the unit itself is ever selected.
What a New Boiler Installation Covers
The boiler itself sits in the basement or a utility space and is the heart of the system. A contractor mounts the unit, connects it to the gas or oil supply, and ties it into the home's existing piping. The expansion tank, which absorbs pressure changes in the water as it heats, gets mounted close by.
From the boiler, supply pipes run through the walls and floors to the heat emitters, whether those are radiators, baseboard units, or radiant floor loops. A circulator pump, usually bolted directly to the boiler or on a nearby pipe, moves hot water through the loop. The thermostat goes on a main living-area wall and tells the system when to fire.
The drawing shows a typical boiler layout, and a licensed contractor determines exactly what applies to your house.

Licensing and Legal Requirements in Kane County, Illinois
Illinois leaves HVAC licensing to the municipality: state law lets the corporate authorities of each city or village examine, license and regulate heating, air conditioning and refrigeration contractors, and caps the licence fee they may charge at $50 — so who licenses you depends on the town you work in.
Severe Weather Events in Kane County
Boiler systems in Kane County work against whatever the climate delivers, and that load varies year to year. How hard the weather presses on a building shapes what a correctly sized, properly installed boiler needs to handle.
