The Caddy Alterna II pellet furnace in the Caddy series

The Caddy Alterna II pellet furnace answers the needs of homeowners seeking the comfort of a wood-heating system without its inconveniences. Tested to the latest CSA B415.1-10  standards, the Caddy Alterna II pellet or pellet+electric combination furnace will please the most discerning consumers looking for an efficient and eco-friendly heating solution.

Great heating autonomy

The Caddy Alterna II pellet furnace offers great heating autonomy due to its 240 lb (110 kg) hopper capacity. Furthermore, its optional electrical system allows it to continue to operate when the furnace runs out of pellets.

Maintenance-free components that prevent unnecessary service calls

Other important features of the Caddy Alterna II include a self-cleaning bottom feed system that keeps the burn pot free from deposits; maintenance-free components (no need to adjust, calibrate, or oil); and a self-diagnostics electronic interface that prevents unnecessary service calls.

Unmatched reliability

All components entering the manufacture of the Caddy Alterna II are carefully selected and sourced from reputable vendors. With an all-stainless steel combustion chamber and burn pot, the heart of your furnace is guaranteed to last. 

Alternate source of heat

With the Caddy series furnaces, you will never again be dependent on a single source of energy to guarantee the comfort and safety of your family. The Caddy Alterna II allows two different configurations: pellet only or combined pellet+electric.



This wood pellet (Premium grade or better) furnace can be installed as a pellet-only unit.

Pellet Electric


This furnace can be installed as a wood pellet+electric combo unit to avoid interruption of your central heating when you are not available to feed the pellets (Premium grade or better). The addition of an electric element is required for this type of installation.
