Furnace vs Boiler in Montgomery County, Tennessee
When a furnace makes sense
If your home already has ductwork in place, a furnace is the simpler system to install and service, with no circulator pump or radiators to maintain. Winter nights here average 30°F, and forced air heats a room faster than water moving through pipes and radiators. With heat needed about 7 months a year, that quicker response matters on the coldest nights.
When a boiler makes sense
If your home already has radiators or in-floor piping instead of ducts, a boiler makes more sense than adding ductwork just to run a furnace. It costs about 5% less to run than a furnace at Tennessee gas prices, which adds up over 7 months of heating a year. Radiant heat also runs quieter than forced air, since there is no blower cycling on and off.
