Furnace vs Boiler in Pierce County, Washington
When a furnace makes sense
If your house already has ductwork, a furnace is the straightforward choice. It runs on natural gas and moves heat through the ducts you already have, with nothing extra to install to get warm air into every room. With ten months of heating a year and winter nights averaging 31°F, you want a system that just runs, and a furnace does that without asking anything new of your house.
When a boiler makes sense
A boiler makes sense if your home is set up with radiators or in-floor pipes instead of ducts. It runs on natural gas too, but it heats water and sends that heat through the pipes already in your walls or floor. Heating with a boiler costs about 5% less here than a furnace, so if your house is already plumbed for one, there is no reason to add ductwork just to switch.
