Fuel usage calculator
Â* Anybody know of a calculator to guesstimate how much wood I'll need
for winter ? Will have to have an "average degree-days sort of input ... I can find tables of average BTU's per unit for most species of wood - I burn red and white oak almost exclusively . Â* -- Â* Snag |

Many variables, of course. These days I find it easier to write a check than split and haul in wood. I do miss using the stove to cook on at times, or getting the fire go down enough to open the doors and grill a steak. |

Is that similar to a gallon of owl? ヽ(ヅ)ノ [8~{} Uncle Curious Monster |

I would ask a few wood-burning neighbours before trusting a guess-work calculator. John T. * New construction , insulated R-11 walls and R-17 ceilings . All double glazed windows and doors . Crawl space insulated with 1" foam as skirting - to be covered with stone later, leaving foam panels in place . I didn't make it super air tight simply because we need some air infiltration for combustion air . But it's not drafty , no big cracks or anything . * I did find some info online , like in our cold zone I should need 3 million BTU's/month as a base figure for a 1500 sf house . I have 3 cords of red/white oak out there , at around 24m BTU's per and 50% efficiency that's enough wood for a whole 12 months . I have my doubts ... I figure that's some kind of average .We like to keep it around 74° , we're sheltered by deciduous woods and down in a holler , and my neighbors were no help , they don't so much stockpile as cut as needed - standing dead if they got it , green if not . They're idiots . I miscalculated last year after increasing the size of the house , I think I actually burned about 2 cords . I'm not planning on getting caught short again . Been cutting all summer in the hope that I can get ahead of things again - and plan on cutting all winter , got a bunch of dead/dying/diseased and leaners marked with orange paint so I can find 'em later . I prefer cutting in winter , no ticks ... * Snag This site agrees that your oak is 24 million btu per cord - but warns that your cord might be only 70 - 90 cubic feet of actual wood - not the full 128 cubic feet - depending on stacking. http://firewoodresource.com/firewood-btu-ratings/ Where did you get the 3 million per month ? ... perhaps closer to 30 million ? in Jan. & Feb, ? dunno.

Â* -- Â* Snag there are new homes being built today that use almost no heat. like a 600 watt hairdryer heats the entire home all winter.. super indsulated r60 cielings and walls, triple insulated windows etc......... when considering the costs of super insulation its not a deal breaker because the energy costs are so low. there are companies building brand new homes of poured concrete, rebar reinforced. a foot thick high strength concrete with storm shutters can ride out a harvey sized storm as long as you are high enough elevation wise |
