http://www.woodheat.com/ - just found this by googling with 'wood heat stoves', never saw it before, never checked the net for wood heat stuff at all ..... but i heat purely with wood, and have for thirty-five years, even when i bought a house with oil back-up once, i just shut it off once the tank ran dry, sold the tanks and stand etc to somebody right away, nobody wanted the ancient furnace so it went for scrap ... no way will i pay for oil when there is wood all around - many years i don't have to fall a green tree, just take windfall from no more than a hundred metre radius from the house [fair bit of root rot in the fir, in some places, so i've been cleaning it up]
Your cost per BTU will be less with wood, even if you have to buy it and pay an exorbitant price, and if you got a deal on the oil ..... even better when you can get the wood yourself, and enjoy the activity .... this sort of pre-supposes that there's wood around you, which is not true for those out on the prairies .... also you have to get as scientific as possible about burning it - thorough seasoning, good dry storage convenient to the stove [but safe!!], well designed stove, religious chimney maintenance, etc ..... but i would consider only wood, for what it's worth ... and if there was no wood around, i'd move -g-
