where we are headed we will need someheat in this boat! Hello I'm Patrick and I'm Rebecca on the Valiant 40 BrickHouse and we're gonna show you how we stay warm or get hot on this sailboat “Brick House”.
Letme show you on the paper chart why we need all this heat.
we get these chartsfrom Bluewater Books and Charts in Fort Lauderdale Florida.
And so we're overhere in the Cape Town South Africa, we go up to St Helena and follow the Atlantic winds right ondown the coast to Uruguay and then down on south where we will be down here inSouth America is another thousand miles south of where we are now so if we thinkit's getting a little chilly in the evening it's going to be cold down here.
We need to pack on the heat.

only the nameis warm so let me show you now just what we did to install the Kubik Cubic mini whichI'm sure we're gonna get a lot of good use out of this wood burning stove! Come on in and I'll show you what wehave to make heat in this boat when it gets chilly.
we'll come back to that wood stovein just a minute – that is the main idea of this whole video so we have thislittle space heater but that doesn't work unless we're on shore power underneath this chart table see we havean engine or bus heater that would be very similar to a car heater.
There is a radiator here afan here to blow air out this is the water hoses coming off of the dieselengine these hoses also heat our fresh water in our newly installed water tankthe water tank was made by Torrid Marine nice stainless steel tank we'll get intothat video at a future date but these go all the way back to the engine room andon this side of the heater we have these two vents so we can direct the air thehot air back and the hot air forward just like in a car and up here on thewall a two-speed switch high and low but of course that operates off the engineand we have to have the engine heated up and operating for that to work we'veused it it really works great.
Another heating option is this pressure kerosenelantern it puts out a lot of light and a lot of heat and of course a bit ofcarbon monoxide so that's only like a supplementary backup thing we'll have acarbon monoxide detector in the boat in the ceiling in several locations verysoon but the main idea here is our new cubic mini grizzly wood-burning stovethe biggest one we could fit in here here the whole thing heats up verynicely and there is a fan right here on top that when this heats up it makes thefan spin and blows the air the hot air around this fan is made by Caframomodel 810 eco fan and we got that from Amazon there will be a link in the videodescription but we already have some wood in herenice hah? so this is what we did to install our cubic mini grizzly wood stove.
So Rebecca this custom wood stove mount that we had made here in South Africa.
Why don't youtell us about it and why we made it here rather than ordering from Cubic Mini Woodstoves?Well to be honest it was kind of a mistake.
I was carrying the wood stoveand the flue pipes in my suitcase to come back here to South Africa fromRhode Island I wanted to keep the weight down I wanted to keep the bulk downand the more frugal part of me thought maybe I could just go and have itlocally made and save money problem was is that it's tough to design their exactsystem I thought I could look online on the Cubic Mini website and get the specs.
Cubic Mini Woodstoves was great andthey tried to work with me even though I didn't buy it from them to get the specsright and the gauge right and the and the measurements right.
but though I wishwe had just bought it and I wish I had just found some space for it in myluggage.
What I did was drill holes through this bulkhead and mount thecustom-made mount in this position this is this refrigerator below here and thefreezer is on the other side so we have the bolts securely holding the top inplace I have this wood screw I've measured just how far it can go inwithout penetrating into the ice box where the foam insulation inside of theice box and to make sure that doesn't happen I have to pack out the bolt alittle bit with the three washers so all the pilot holes have been drilled we'reready to put this in and screw it in place with the mounting bracketssecurely fastened with four bolts onto the bulkhead now we just simply hang thecubic mini grizzly onto the two U hangers line those up and just drop them both in andthen at the bottom end there's two more holes to which clips are just insertedand so it's held in place with four points butthose are the tough ones to get to I had to use needle nose pliers to get wayinside to force those clips into their proper holes I wanted everything just ashigh as possible so that underneath we can fit our feetthen we don't ruin this whole bunk for sleeping purposes or for storageunderneath also I had to have this furnace mount over enough so we can open the doorbehind this backrest to get to all of our valuable storage behind it on thisside this cap this teak cap overhangs so on this side I did not want to cut thatcap back for this mounting bracket to fit flush I used a piece of vermiculitethis is five eighths of an inch thick which is about 13 millimeters thick as abacker fireboard and also additional insulation to the wood bulkhead thispart of the insulating mount is actually hollow on the inside so hot air comes upthrough the bottom and out these holes on the top the same hollow panel designused on the backside of the cubic mini is vital to keep any heat buildup fromtransmitting to the wooden bulkhead and we have this one to mount on this sideto help keep all that hot air away from the cushion and our storage area overhere and on this side on the starboard side we just have a little heat deflector wealso do have one of these custom walls that we can put on this side but if weso choose but I think this little deflector is going to be plenty good tokeep heat away from the plywood bulkhead and also allow hot air to come off tothe side and circulate through the cabin this vermiculite is the same materialthat the insulating bricks inside of the stove are made of and it's the samethickness 5/8 of an inch 13 millimeters so it's very easy to cut with a sabersaw or a table saw it's actually pretty soft if I took my hand and rubbed itacross it probably flake off kind of like like styrofoam balls do so as it'sset up here heat will actually come up through this insulated pipe because thisis an outer core it goes up through here and then out through the top so my jobtoday is to figure out where the center is so Ican drill a pilot hole up here and then measure from the outside where I'm goingto cut the circle for the stovepipe to come up and for this cap to mount theflue really needs to be a straight shot straight up no elbows no angles so noneof this will be seen from the inside but this venting plate will so the hole thatI'll be cutting up here later today will be big enough so they'll be comingaround all of these vent holes so air will come up through here andcirculating around in this area to help keep everything cool now the big concernthat I have is just how high should we make this stack actually the higher thestack the better for drawing hot air out of the cubic mini wood stove but we can't go sailing around with a stack that's like you know two feet or a meter off thedeck of the boat we will have a just this end cap which will have a weathercap on it but when we go to use the cubic mini then we'll add this stack andthen use the cap on top of that this cap is that like a wind deflector and ifeverything works properly the wind will actually go through here and help drawhot air out of the stove these parts are all made by Dickinson Marine and weordered them through Fisheries Supply in Seattle Washington.
Fisheries Supply.

that's a misleading name although they sell a lot of fishingequipment and commercial fishing gear they sell a lot of sailboat andpowerboat equipment so what we will be using while we're traveling is just thison the deck will get rid of any stacks again the cap and just put this cap ontop to help keep grain water and sea water out but the problem here is theseare just tack welds around the base and at the seams the same for the cap I canlook inside of here and actually see daylight coming out the bottom where thetack welds are so you can't imagine how tremendous waves can be washing over theboat waves will back up through here and get inside and come through the boatso let me show you what I'm talking about here although this is tack-weldaround this perimeter it there's a lot of little welds on the seam we'll putsome water in here and you can see it just dripping out if water can come outwater will certainly get in so on the inside of the cap here I'll be usinghigh temperature silicone to seal the inside edges on this cap and also waydown inside here I'll be sealing it up very well to make sure that any waterthat splashes around this area does not come back through the seams or the weldshigh temperature silicone is incredible stuff that has a very high temperaturerating although when we put this cap back on all of this should be prettywell cooled off but I don't want to take any chances of any mistakes so we'll beusing the good stuff on this cubic mini wood stove installation.
I wouldn't use just regular silicone onthis so that's my project today let's get started I'll figure out where thehole is drilled up and start cutting a big hole in the top of the boat okay soI want to project up here figure out where I'm gonna be making these holesyou know you always hate putting holes in your boat and then thinking you'reruining the cosmetics and everything else but let's see what can I do here okay soto get a projection up I'm gonna take this “beware of the dog” sign which weonly have a cat on this boat but you know grandiose ideas and I'm gonna rollit up here okay that gives me this insideprojection actually let me bring this back down I sure would like to avoidthat trim strip and bring everything this way how about if you took the widthstrip down put it on there and then put the wood strip over it because it's notdoing it over the holes it's a good idea okay that's what we'll do then yeah Ithink it looks good all the way around okay and I'll see if I can just makesome marks around this outside perimeter and then find a center point from that so whenever we take things apart I havea dedicated jar for any screws that come out certainly helps for a reassemblylater on trying to find parts as long as I can find the jar okay so from the aftend of this window to let's see where's that center point right here that'sabout 29 inches 74 74 zero millimeters you'll see where we come up outside bring it about right here okay I'm goingto shiftthis off this way just a little bit so this venting plate the edge ofthe bit will wind up halfway on to the trim strip that goes here these holes will be just on the outside of that trim stripthen we need to mark the inside of this hole here Rebecca I can drill up throughit the diameter of this drill bit doesn'tmatter you have our center hole right here putthe ring over it get the dirt out of the way and Mark it out we have a three inchdiameter flue so I am making a five inch diameter hole there needs to be at leastone inch clearance all the way around the flue as it comes up through the deckdrill some more relief holes here for when we cut I don't want to have tostart cutting here all the way out to the end and then make a circle right outhere on the circle okay what I'm gonna do is drill two moreholes side by side to make sure they're wide enough for the saber saw blade tofit into so I can go ahead and cut the circle rather than going to the storesyou get supplies sometimes it's faster and easier just to pull what I need outof the dumpster and the drop cloth covers everything forgood measure I'm using an Allen wrench in theelectric drill to knock the balsa coring out of the way and then we'll go backand refill the void with thickened epoxy resin do you see that green bonding wirein the bottom right of the hole that got nicked by the saber saw but we don't usethat bonding wire anyway so we got lucky on that one this is epoxy resin thickened with Cabosil and I want to cram it just as much as I can back into these voids to makesure everything is filled solid with the epoxy so now I set the rubber seal inplace and then the deck fitting on top of that and drilled pilot holes downthrough each of the mounting holes in the deck fitting I wanted to makeabsolutely sure that these screws were going into solid epoxy resin and notinto any kind of a void or missed balsa coring a bit of drum sanding willsmoothen out the epoxy resin and get it ready for the next step of laying insome fiberglass cloth I want to put this plastic up in here hoping this slot justto make sure that no resin drips down past there and causes a problem insideof the cabin here or on our ceiling okay that's looking pretty good from below two layers of lightweight boat clothwill be extra insurance to make sure that no water can get past the rubberseal or even the high temperature silicone I'll be sealing this whole areawith I'm gonna pull this tape up before this epoxy resin sets up completely Idon't want to glue all of this to the surface and then have to scrape and chipit out so this is still a little soft well it'll it is soft and while theresin is still soft this is a good time to make sure that the rubber sealingring can fit over it that vertical fiberglass flange it's going to actuallybe able to extend a little further back up in to this cone area so I'm going tonot cut it flush with the ceiling gasket but raise it up just an eighth of aninch but there was enough room I could have raised it up a half or eventhree quarters of an inch would have been better surprisingly the epoxy didit here pretty darn well to this old plastic sheeting but the dremel tool wasa good tool to cut it all out with are you thinking what I'm thinking I'vewatched a lot of Cubic Mini installations on YouTube and I hadn'tseen anybody else install a metal heat shield up in the ceiling area and onlyafter we completed this wood stove installation did we contact cubic mini and went over thedetails and they said yes we should install a piece of metal like infive-inch diameter flue cut to the proper size in this area as an extraheat shield copper or aluminum won't work they transmit too much heat so ithas to be stainless steel I'm not going to rip out the whole deckand do it all over I will be able to cut the piece to the height that I need andthen cut it lengthwise slip it over the existing pipe and up into this void areato help give the protection that Cubic Mini would like to see and let'sconnect some pipes so this one will go on top of here andthis one it's going to fit this will go inside the inner pipe and this will gooutside the outer pipe but before we do anything else we need to take the little Cubic Mini wood stove outside and start a fire in the box just as hot as we can and let that go foranywhere between one and three hours to help cure the paint and reduce any kindof odor or smoking after we do install it in the boat permanently so with theburn complete now we can set up the pipes to go up through the ceiling andjoin up with the Dickinson deck fitting and determine just where to cut one of thepipes to make it all fit and go ahead and complete the installation okay sothis is goin.
This Dickinson deck cap is going to sit right flush right down on top of thefiberglass top this will be projecting up into it and I want it to come up thiswill be going down over this inner pipe for this application the deck fitting ismade wrong it does not fit inside of the pipe where it should it will only fit inthat slot between the inner and outer pipe but the tack welds are in the wayso it just won't fit on this end so I've got to cut this this pipe coming upthrough the deck in an area that's just a proper height and I want this thoughthe inner pipe to project up in here 1 and 1/2 inches past the deck it'll comeup right about here I don't want to cram it up all the way to the top and whatI'm going to do is take this rubber sealing ring out of here this is 1 in1/2 so I'm just going to take this and mark it at 1 on 1/2 inches all theway around running a line of tape around to match up all of these marks will makeit a lot easier and much more precise for making the cut with an angle grinderwith a metal cutting blade in it this is far easier than using a Sabresaw you know when this pipe goes togetherthis one goes actually inside here that seems a little counterintuitive becauselike you think smoke would then be able to come out and around but there is aflange that the pipe rests on inside of the stove creosote that builds up in thestack well then as it drips back down which are gonna it's going to happenwith any wood-burning stove that creosote will drip down into the stoveand then get reburn if creosote dripped down the outside you would have a tremendousmess dripping down around the top of the stove and this insulator part of coursegoes on the outside this insulator pipes help to keep the gasses inside of theflue pipe hot for proper venting but this outside pipe will also get very hotto the touch so it shouldn't be touched when there is a good fire going insideof the Cubic Mini wood stove now it's time to put it all togetherI would never rely on just a gasket to seal on a sailboat installation likethis so I'll use a liberal amount of high temperature silicone to help outbefore inserting the inner pipe the one that carries all the hot gases out ofthe Cubic Mini wood burning stove into the deck fitting.
I smeared the joining surfaces with hightemperature silicone now on the outer flange and everything else I'll also usethe high temperature silicone to help seal the entire join and make sure it'swaterproof a good dab of silicone will go on all the screw holes to help sealthe screw heads silicone will be used to seal up some of these joins that arejust tack welded or overlapped to help make sure no water can get in mineral spirits and paper towels does avery good job of cleaning up the excess before silicone has a chance to dry wellwe're here let me show you one mistake that I made this Coach roof has a slightslope off to the port side for drainage when I installed a deck flange I justscrewed everything down evenly and I didn't compensate for this slope I couldhave just tightened down the inside uphill screws and left the downhill sidescrews a little bit loose and let the silicone sealant make up for that slopeor I could have made something out of plastic and a wedge to help make thislevel why that's a problem it now this pipe comes down inside at an angle Ididn't think it was going to be that much of a problem I thought it wouldjust twist and you know so find it sits vertical but it didn't so it's a bit ofa tight squeeze inside I can make everything go together pretty nicely butit's just not a natural fit I have to force it it would have been better tocompensate for this deck slope we have a couple snags here everything is set upand we can pull the a grain cap off this will fit very nicely on top but thething is I just don't like how low it is to the boat if we have fire in thefirebox smoke is coming out here I want this higher up to have better dispersionof the smoke away from the boat so in order to do that we have an extra stackpipe here it'll fit in very nicely you will almost nice things rather loose butthe problem is this will not fit in the top it will not fit inside of the fluepipe like it should so but it will fit improperly on theoutside of the flue pipe on this end so I'm thinking what to do I'm gonna justcut the top off here and get rid of this crimped area so we'll have that'llactually also eliminate the welds holding this double walled pipe together but that's fine all right so what I did I took that angle grinder to cut thisflanged in because it's welded tack welded in one section so you come out topieces so now this will fit inside here the cap is not made properly it fits onthe outside it should be going in the inside but we have to live with it so wecould just leave it like that then you are Kubik mini do it suffice on fairlycalm day with the wind not really blowing hard it's a little wobbly butit's really best to have the double pipe on here to help keep this part of theflue hot this helps with the air flow we don't want it cold we lecture so justtake our other section I have cut three slits along the bottom one two and threeso it fits down very nicely over the base here but I can put a hose clamp onhere if I feel like we need to and that'll hold it nice and tight on thetop now this will go back down outside of theproof pipe and the inside of the second wall this fits down inside snug fit andwe're good to go ready for a fire in the wood stove and when we are readyto cross an ocean we'll just use a littleGorilla tape around the seam forextra security so when we decided we needed some serious bits of heat onour sailboat Brick House before we could go to Patagonia or anywhere cold I did athorough research of everything that would work for a 40-foot cruising sail boat and acouple things that were my fundamental requirements were a dry heat right nowwe're using in South Africa a quartz heater and it's making massive amountsof mildew and all the humidity in a living space is part of the air thatgoes into the firebox and out the chimney that air in the living space hasto be replaced somehow and it comes from the dryer outside air so it reduces thehumidity in the living space and this is what happens with a wood stove one andtwo we wanted something that had that used a fuel that would be easily easilygotten while we're in Patagonia where there's not a lot of stores there's nota lot of gas stations there's not a lot of anything there and we might be downthere for six months and we also don't have an abundance of electric power on our sailboat Brick House so we needed something that wouldn't use a lot of electricity andwouldn't have us struggling to replenish that electricity all the time as we staywarm.
installation was also an issue we didn't want a complicated system so thefirst thing we considered because Brick House used to have an Espardiesel heater on the boat which is a diesel powered and electricity powered unit andyou have ducts that go all over the boat so we kind of ruled that out fairlyearly one because everybody that we talked to that had a boat heater like thatloved it but it was broken on every last boat that we asked they loved it but itwas broken right also because of the electricity that it uses it uses a goodamount of electricity every hour that you're running it the second thing thatwe considered was a propane stove you know propane like Dickinson marine kindof thing but the problem that we come back to with that is thatpropane is a very wet heat so you know all of our closets everything inside of allof our bunks everything would be moist and you're not gonna be that warm if youhave a moist heat going on to go around for six months we'd need 12 bottles 12big bottles of propane .
.
.
the kind that you put on your cookers at home and were not storing 12 bottles of propane on the decks of Brick House the other solution was maybe a Dickinson marinediesel heater that has an electric assist on it which that was aconsideration as well except for the biggest unit that they make isn't reallybig enough to heat Brick House, a 40 foot sailboat, so what we ended up with what you know what made the mostsense for us was to get a little wood burning stove so we went with cubic grizzly – a cubic mini grizzly and they're out of Canada but this is a tiny little thingyou know we had to do a lot of comparison between their cub model vstheir grizzly model to see what would heat our both the best.
The grizzly wood stove from Cubic mini covers a square area of up to 400 meters I calculated our squaremeters very roughly and I think we're at around 300 the cub heats about 200square meters so that one I think was gonna be too small and it's only amatter of an inch on each side so we went with the bigger wood stove to make sure willbe plenty warm and also so we could have tiny bit bigger logs and a little bitmore capacity to burn a little bit longer so we decided that wood was themost economical for us and wood would be the most easily foundso we've installed the Cubic Grizzly cubic mini Grizzly it's a cute littlestove it heats very nicely and can't wait to start using it even more!.
