In your situation in Newfoundland a PSG Caddy will likely be the easiest to find as well as a dealer network, qualified installer, service tech etc. All of which are important for a heating unit that you may have a 20 - 30 year relationship with. The wood consumption in your above post is excessive to say the least unless you are heating 10k sq ft or more & poorly insulated at that. Seems we have very few happy owners of combo units, likely due to both designs being compromised. Myself I would have a dedicated wood unit & a separate unit for backup fossil. Buy the best quality that my budget could afford in both cases.
