Furnace vs Boiler in Kent County, Delaware
When a furnace makes sense
If your home already has ductwork, a furnace is the simpler choice, and it's what just under half of homes in this region run. It heats the air fast, which matters on the nights here that drop to 28°F, and the same ducts can carry air conditioning in summer.
When a boiler makes sense
If your home is set up with radiators or in-floor pipes instead of ducts, a boiler is worth a look, and it runs about 5% cheaper to operate here. Boiler heat also holds steadier through the cold nights, since the radiators or floor keep giving off heat after the burner shuts off. It won't do anything for cooling, so you would need a separate system for that.
