About Wood furnaces - Southern Ohio Wood Boilers

The cadillac of furnaces is now better than ever and you should know that the advanced combustion tetchnology and state of the art design have earned the Caddy furnace a reputation due to the cleanest and the most efficient furnace that they ever produced by PSG. Today with the electronic components and controls of the newly redesigned Caddy have been reduced to just 3 components for greater ease of use and efficiency:

– An integrated PC board and RTD probe to control blower speeds and plenum temperatures, optimizing home comfort and furnace performance.

– A blower assembly equipped with a prewired main power board for plug and play convenience upon installation.

-A touchscreen LCD control module to make input and output control a breeze.


The secret behind the Caddy’s outstanding performance is its built-in heat exchanger system, which ensures that heat is transferred quickly and efficiently via the smoke ducts inside the furnace instead of being lost up the chimney.  It uses up to 30% less firewood and reduces particulate emissions by as much as 80%. That’s great news for your heating bill—and the environment!

Alternate source of heat

With Caddy series furnaces, you’ll always have an alternate source of heat to ensure the comfort and safety of your family. The Caddy comes in four different configurations: wood-only, wood+electric combo, wood+oil combo, and wood add-on furnace.
