size of heater in wheelhouse

11 posts in this topic

I just bought a 6.5 x 14 ft ice castle fish house with 3 ft v-front. I got the house wrapped, so I plan on insulating with

R-13 batt insultion in the walls and roof. The floor at this time will be un-insulated, however, in the future I plan on getting it sprayed.

my question is, how large a heater do i need to heat this house? Would 20000btu be sufficient. I would like to get a small enough heater so I don't have to use 100lb tanks.

usually 1000 btu's per foot is a good estimate i would recommend using the foam insulation instead of batt insulation

I was just looking at a replacement heater for my fish house and it was a 15,000 btu and said it was good for a 369 sq Ft house, that works for my little 6 x 8 wheelhouse call it a 7 ft ceiling. Check out the spec sheet of the heater you're looking at. You're looking at approximately 546 sq Ft. 20k might not be enough with the floor not insulated, but I can't see it being beyond tolerance if you wear sweatshirts instead of tee -shirts. It might be just right once you insulate the floor. Don't go ventless on this size house, if you plan on sleeping in it. Direct Vent is the safest way to go.

tb2- are the ratings in square feet or cubic feet. You are stating capabilities of the heater in square feet but figuring the size of your house at cubic feet. Huge difference. I have heated a 12x14 tent in 0 degree weather with a 30,000 btu heater. I heat my portable fishouse approximately 6x6 or larger with a Mr. Heater 14,000 btu in below 0 windy weather on medium. I would suspect the 1000 btu per foot of length to be a good rule. Not to be nit picky but this is a major difference

My wheeel house is 6 1/2' x 12'. I have a 15,000 BTU direct vent heater and it is plenty for a hou8se this size. I run a couple of computer fans near the ceiling to circulate the heat. It is insulated with 1 1/2" foam sheets. Once I get the interior warmed up I have no problem with it getting cold and can fish in a T Shirt.

20,000 btu will be big enough. I have a 20btu in my 16X8 and heats it just fine. Also dont put to much into square footage equations. alot of it has to do with how tite the house is and if you bank it good when fishing. You could have a 40,000 btu furnace but if you have cold air blowing in a fish hole or through a wall it wont be big enough

I have a 15,000 btu in my 8'x16' fishouse with an 8' cieling height and this heater will cook us right out wen turned up. I keep it pretty low to keep from getting to warm. Like said, banking is a big factor, keeping the air flow from coming in under the house. Also my floor is not insulated and I used R-13 bats in the walls and roof.

My house is 6x14 with a v front I had a 9000 btu vent less and now I have a 18,000 vented. Both heated great. I never been cold with ether one and my floor isn't insulated ether. Just keep in mind if you go vented you will need more btu's then if you went non vented because a non vented is 99.9% efficient and a vented is less.

input btu x efficiency = output btu

    • It is summer bacon season, plus they have gotten trendy on their own.  
    • Fletcher must really like these guys that are small and quick.  I don't understand why they are trying so hard to keep the team intact.  They haven't made it past the 2nd round for the 5-6 years.  We've had this discussion before, but at what point do you say this just isn't working as is?   They have to move good players to get good players.  
    • I look at it like cast iron....numerous cookings give 'em a perfect seasoning. Gotta leave some residue on IMO.
    • No butcher buddy? They can order one for ya....be advised they have taken a huge leap in prices. Ask a butcher about that. Mine (who's also a good friend) said it's the highest he's ever seen 'em at right now.
    • jhust find a locker plant that smokes their own bellies and buy one from them.
    • I have seen it in Costco quite often.  Didn't look last time.    Or call around, often the meat markets will special order if desired.   Seems it was in the 3 buck a pound area if I remember right.     I don't know how far from a Costco you are, but they are a good place to buy meat.   Sams Club might work also. 
    • Pretty hard to tell. Is this on a TWSP, County or State road? You will need to get a permit from them and build it to their standards if approved. Will you need a culvert? Probably will unless you locate it at a highpoint. Will you have to remove any trees? How much fill is needed? is the ditch deep or shallow? How long do you want it? Hopefully you are not impacting any wetlands... It use to be simple, but now it is much more complicated. Could get spendy...
    • Since my smoker is new for now I throw them in the big wash sinks in the basement with some Dawn and hot water to soak. Then rinse them with more hot water. I'm sure in time once they get more "purplefloyd seasoned". I'll rub them a bit with a grill brush and hit them with a garden hose! 
    • Hello from the NW Angle of Lake of the Woods!

      Here in Minnesota, water temps are in the low to mid 60’s and the Walleyes keep rollin’ in! Wind blown shorelines are giving up walleyes via leeches and crank-baits right along the weed line. Crawlers on a gold and/or orange spinner are producing fish out of the mud between 22 and 26 feet. Jigging has been tough this week with the strong winds, but the Mayflies have finally tapered off!!
       
      Up on the Canadian side, bottom bouncing has been filling the live wells outside of monument bay between 24-28 feet.  Jigging near Skeet and Kennedy Islands have seen nice sized walleye and numerous perch. Great smallmouth action can currently be had in Tranquil channel and the mouth of Johnston passage. Muskie fishing is still sporadic with high 40” class fish being caught from shallow bottom bays or just outside of them. 

      Fish of the Week:
      49" and 46" Muskie
      40" Pike
      At least 10 Walleye over 25" 

      We hope to see you soon! Sunset Lodge
    • Anyone know where I can find it?  Checked a couple grocery stores and even a butcher and nobody has it?  Also what's a decent price if I do find any?
