Furnace vs Boiler in Washington County, Utah
When a furnace makes sense
If your house already has ductwork, a furnace is the straightforward choice. That same ductwork can carry air conditioning too, which matters once temperatures climb in summer. Across this region most homes are already set up this way, so a furnace fits without any change to how heat moves through yours.
When a boiler makes sense
If your home heats through radiators or in-floor pipes instead of ducts, a boiler is the machine built for that. It runs about 5% cheaper here than a furnace, which adds up over the eight months a year this county needs heat. It won't move air for cooling, so you would need a separate way to handle that if you want it, especially with winter nights averaging 28°F here.
