MAX Caddy Heating Area:  1,500 - 3,500 sq ft Size: 36 1/4" W X 60 1/8" D X 50 1/2" H Maximum log length: 25" Average particulate emissions rate: 0.753 lb/mmBTU (0.326 g/MJ) Ingenuity 2.0 PSG’s largest furnace is now even smarter, with a new electronic platform that facilitates intersystem connections and makes the Max Caddy a natural choice as a core component of your whole home heating and cooling system.  The power to communicate Max Caddy’s new streamlined electronic platform makes it easy for different systems to talk to each other. Heat pumps, air conditioners, humidifiers—the Max Caddy easily communicates with all of these appliances using standard industry symbols and practices. Easy-to-identify input and output ports and a blower assembly with prewired main board simplify installation and hookup. And PSG’s touchscreen LCD control module makes input and output control a breeze.  A benchmark for efficiency The Max Caddy’s integrated control PC board and RTD probe automatically ensures that the furnace blower is operating at optimum speed, keeping the plenum at just the right temperature. The built-in heat exchanger system ensures that heat is transferred quickly and efficiently via the smoke ducts inside the furnace instead of being lost up the chimney.  The result is superior comfort and energy efficiency, with savings of up to 30% on firewood and reductions in particulate emissions up to 80%. Multi-energy flexibility and peace of mind The Max Caddy can be installed as a wood-only unit, but is also available in wood+electric, wood+oil combo, or even wood+oil+electric triple combo configurations so you can heat your home using multiple energy sources. With Caddy series furnaces, you’ll always have an alternate source of heat to ensure the comfort and safety of your family.
