Furnace vs Boiler in Pueblo County, Colorado
When a furnace makes sense
If your house already has ductwork, a furnace is the straightforward choice. Most homes in this region were built with ducts in place, and a furnace uses them to heat every room. With eight months of heating ahead of you and nights averaging 19°F, you want a system that matches what your house was already set up for.
When a boiler makes sense
A boiler makes sense if your home heats through radiators or in-floor pipes instead of ducts. It runs about 5% cheaper than a furnace at Colorado prices, which adds up over an eight-month heating season. Where it doesn't fit is a house with ductwork already in the walls and floors, since that setup was built around a furnace, not the pipes a boiler needs.
