In floor radiant electric is going to be expensive to run. Delivery fees for electricity in the boonies are higher as well, so that makes it even harder to swallow.
Like you I use an outdoor wood furnace. Hot water radiant heat is pretty hard to beat.
You might want to check out Northern Stoker wood furnaces, out of Sunderland. He has an auto feed option for pellets, sawdust etc.
We have a propane furnace for backup. When it fires up I can practically see the dollar signs spinning in my head.
