Furnace vs Boiler in Naugatuck Valley Planning Region, Connecticut
When a furnace makes sense
If your house already has ducts, a furnace is the straightforward choice. It runs on natural gas and pushes heat through the ductwork you already have, and with winter nights here averaging 22°F, you want a system that can recover fast on the coldest stretches. The same ducts can carry air conditioning too, which a boiler can't do.
When a boiler makes sense
If your home heats with radiators or in-floor pipes instead of ducts, a boiler is the natural fit, since it delivers heat through that piping rather than blowing air. It runs about 5% cheaper to operate here than a furnace, which adds up over the roughly 8 months a year this region needs heat. It won't do anything for cooling, so you'd still need a separate way to handle summer.
