Jotul F118 CB Application

[Underblog]

I am looking to install an (broken link removed to http://www.jotul.com/en-US/wwwjotulus/Main-menu/Products/Wood/Wood-stoves/Jotul-F-118-CB-Black-Bear/) in a 900 sq ft cabin (600 sq ft plus 300 sq ft loft), using it for sole source of heat three seasons. Is the size adequate to my needs? The cabin is fairly recent construction and we are outfitting it with closed-cell insulation.

I thank you all in advance for your assistance

Will you be heating the place from dead cold? If so, how fast do you want it to be warm? What R value will you be insulating to?

For the most part, we will be using the cabin from April or may through October. However, we would like to visit occasionally when the frozen lake makes the cabin accessible in winter. It gets seriously cold up there (this week it was 25F below 0), so I would like to have stove capacity be sufficient for that application.

The R-value of the closed cell is not appreciably different than the rolled stuff, but I hear it minimizes drafts. Basically we plan on insulating the walls and roof and floor to whatever the construction allows.

I reckon that speed to warm is not too terribly important, since the difference between the inside and outside temps will be so great.

should be fine or go with f3cb but bigger of fire window. but blk bear is a kick as stove.

I'm thinkin that stove will handle the -25 °F , but I wouldn't
try to bring it up to operating temp from that low. It would seem
to me that that bad boy would crack from that big a change
in temp in a short period of time, & it's kinda pointless to have
a break in fire when you need it to crank. Just my $.02...
Maybe others who HAVE done this successfully will chime in.

I have a similar situation in NY with a cabin on a lake. I've found that warming it up from cold in a decent amount of time takes a lot more energy than one would rationally believe. I've used over 100btu/sq ft to raise it 2 degrees an hour in strong wind.

Before spending a large amount of money to see if a stove is large enough, try running a kero heater or two in it to see how fast that temperature rises to the point you feel comfortable. A little bit of information on how the structure reacts to heat will help you make better choices.

I think I would put in a bare simple steel stove like the Drolet Escape 1800,True North TN19 or Englander 13NC.

I broke in the stove while up there -- that Black Bear really gets things toasty when you get the temps up to 400F. I cannot imagine how hot the place would get when the stove reaches the recommended 500-600 degree range. One suggestion I received when up there is to use a small space heater to pre-warm the wood stove before making a fire in it, to prevent the stove from heating up too rapidly.
