Furnace vs Boiler in Washington County, Rhode Island
When a furnace makes sense
If your house already has ductwork, a furnace makes sense, and just over half the homes in this region are set up that way. It runs on natural gas and heats through the ducts you already have, so there's nothing new to install to carry the warm air. Winter nights here average 24°F and the heat has to run about eight months a year, so you want a system that keeps up with both, and a furnace does that through ducts already in place.
When a boiler makes sense
If your home heats through radiators or in-floor pipes, a boiler is the fit, since that's how it moves heat. It runs on natural gas like a furnace, and boiler heat costs about 5% less here at Rhode Island prices. With winter nights averaging 24°F and heat needed about eight months of the year, that lower running cost adds up over a long heating season.
