What do you get when you take PSG's largest furnace and make it even smarter by giving it a new electronic platform to facilitate the inter-system connections? The redesigned PSG Max Caddy EPA Wood Furnace! The new streamlined electronic platform makes for easy communication between different systems, heat pumps, air conditioners, humidifiers etc. by using standard industry symbols and practices. Easily identifiable input and output ports and blower assembly (with prewired main board) means installation and hookup is a breeze. Adding another layer to the ingenuity, PSG has added a touchscreen LCD control module for straightforward, uncomplicated input output control. 

The integrated control PC board and RTD probe automatically verifies the furnace blower is operating at it's optimum speed, maintaining the plenum at the perfect temperature. Using the built-in heat exchanger, the Max Caddy ensures heat is transferred quickly and efficiently through the smoke ducts in the furnace instead of losing potency through the chimney. The result? An exceptionally comfortable and energy efficient furnace that creates not only 80% less emissions, protecting the environment, but also saves up to 30% on firewood, which transfers into pocket book savings for you. 

The Max Caddy EPA Furnace can be installed four different ways: Wood only unit, Wood and Electric unit, Wood and Oil unit, or Wood, Oil, and Electric unit for a triple combo to allow you to heat your home using what works best for you. Rest assured that with PSG's Max Caddy series, you will always have an alternative source of heat, creating both comfort and safety for you and your family.
