Difference Between Forced-Air Heating and Hydronic Heating
Forced air systems use convection to heat your home: your furnace draws in air, heats it up and then circulates it through your home. Hydronic heating systems use heat radiation to heat your home. Heat radiates out from the radiators in your rooms or from the pipes in the floor. Thus, hydronic heating systems actually heat the objects in the room instead of heating the air.
How Efficient is a Hydronic Heating System?
Hydronic heating systems do offer homeowners some energy advantages over forced-air systems. One of the main advantages is that radiant heat is easier to retain in a space than convective heat. This allows hydronic heating systems to use less energy to keep your home warm. Also, many hydronic heating systems feature zone control. This allows you to only heat the rooms in your home that you’re using instead of wasting energy heating other, unoccupied rooms.
