You spoke, they listened, introducing the newly redesigned Caddy Alterna II Pellet Furnace! Answering the call of homeowners looking for the comfort of a wood-heating system without the inconvenience, and tested to the highest standards set by the EPA and CSA B415.1-10. The Caddy Alterna II is available in both pellet unit or a pellet/electric combination unit to fulfill everyone's needs, pleasing even the most discerning folk looking for an Eco-friendly, efficient heating solution. 

Thanks to it's 240 lbs hopper capacity, the Caddy Alterna II provides great heating autonomy, and by adding the optional electrical system, it can continue to operate once the pellets have run out. To top that tidbit off, PSG has made certain components maintenance free meaning no need to adjust, calibrate, or oil, and a self-diagnostics electronic interface prevents unnecessary service calls. And of course you can't forget the the self-cleaning bottom feeder that keeps the burn pot free of deposits.

With an all stainless steel combustion chamber and burn pot, the heart of your Caddy Alterna II is guaranteed to last.
