Furnace vs Boiler in Elkhart County, Indiana
When a furnace makes sense
If your house already has ductwork, a furnace is the straightforward choice. Most homes in this region are set up this way, so you are not paying to add what you already have. It runs on gas like the boiler, and with eight months of heating season and nights averaging 20°F, you want equipment that matches what is already in your walls.
When a boiler makes sense
A boiler makes sense if your home heats through radiators or in-floor pipes rather than ducts. It costs about 5% less to run than a furnace at Indiana gas prices, which adds up over eight months of heating season and the cold nights here. If your house was never set up for ductwork, a boiler works with what you have instead of asking you to install something new.
