hi guys, I'm new here and could use a bit of help. I have a secondary residence in the northern part of wisconsin. we primarily heat with a lopi berkshire LP stove, but supplement with a jotul gf200 and our wilkening convective wood fireplace. I'm wanting to be able to do some puttsing around the detached garage during the winter and am looking to purchase some kind of heater for it. the garage is 25x28 with a barn style roof. it is fully insulated and I plan to cut vents in the second story floor so the heat can rise to some degree. this is not something that will be heated 24/7. I am looking for opinions on whether I should simply throw in an LP stove that being the jotul gf300 i have sitting or if i should go with wood as its a bit less expensive to burn? I have a line on 2 smaller jotul combifires both under $400 if i were to go with the combifires what are the pro's and cons as well as dimension differences between the 1B and the #4. both are odd looking , and from what limited info Ive gathered, the 1b is brick lined the 4 is not. HEELP !
