General Outdoor Furnace Discussion / Re: It's staying cold!
« on: March 07, 2019, 03:37:30 AM »
Going to get more wood tomorrow . It might just brake 2 nd coldest winter in 20 years time will tell.. but ya wood stuffing at 15 cord about or 54,480 lbs of oak slabs under 20% that's some serious BTUs system working good heating 6600 sqft .. average 473 lbs a day and we had 2 polar vortex out brakes there reason for me running out of wood they double wood consumption. The -33.5 f one in Jan 29th it took 2270 lbs of slabs in 2 days . Shocking wood vanishing.

Here did more math nailed down my average per day 473 lbs a day keeping 6600 sqft at 63f . I did it like 4 different ways. Always came up 473 lbs .. I stuffed in 46,353 lbs so far .. it's like 165,000,000 BTUs to the buildings . I started with 400,000,000 BTUs of wood . Thinking houses take 200,000,000 BTUs . I'm going to run out early ... Yep .
Polar vortex pretty much screwed up my projections .

Great idea . But if it's loosing heat for the 12 hours you use it . Why not just Insul seal it and be done with it . I have 50 feet of Insul seal on one of my zones temp drop is undetectable . And a 130 foot run sprayed in polyurethane 4 inch on 3 side 10 inch on top with pex Al pex .looses about 1.2 degrees after 23 years in heavy clay . Other run I have is 110 feet looses 1.1 degrees after 23 years .. So story is you need 2-4 inch polyurethane and water tight once have that you can bring heat Los to minimum. I tested mine in winter . Not on hot summer day . Cold penetrates a lot better than everyone thinks. 👍😳 It's shocking .
I feel pretty lucky spray in polyurethane still hanging in there after 23 years . Back when I installed spray in polyurethane was cutting edge .

I like how you can really nail down the worst winter . It justifies why certain years took so much wood. Looking like 2018-2019 going to be for sure be in top 5 of last 20 years.

I found a better site weatherdatadepot.com to figure out heating degree days . Yes in ground heat loss is evil . I'm loosing 2.03 degrees in 274 feet in the ground 3 zones. This charts at 63f and just look how nasty 2013 and 2014 was.

Math revisited... Ok Nov 16th 2018 to February 12th 7634.9 degrees days . Total wood burned 43,130 lbs so each degree takes 5.64 lbs of wood . Now I'm burning slabs 14-20% figuring 7100 BTUs per lb . 40,044 BTUs in to boiler per degree . So if I need 9000 degrees for total season. I need 7699.16 pounds yet that's 3.39 bundles now that sound like not enough .. so the issue will always be how many degrees days are there perseason . Kinda like a horoscope reader.

I'm going look in to this closer . Because I think average degrees days for Minnesota has to have one mean swing . Closes weather station that has records for longest time comes to play . I'm right between Duluth and twin cities so I can average between the to. There the ones with oldest records. 8600 degrees days maybe . But that degrees days website pretty awesome. I got a weather station all set up so . Still need boiler data logger yet from RSI I'm getting there . Once I know boiler temp drop with weather temp . I can nail down my pounds of wood per degree right now Math is saying 8-9 pounds per degree .
That one polar vortex day math says 1250 lbs of oak slabs that's pretty dang close .

Yep find your degrees days where you live. And the amount you burned.
So you can find out how many pounds it took for a degree . And also find the average degrees days at your location per season. DNR in Minnesota said 7896 for twin cities average degrees days per season.witch is about 3 degrees warmer then. Me .

That says I need 7.38 bundles yet and I only have 7 left . That's with a DNR average of 7896 heating degrees days .. might have to get couple more bundles or cut up some nasty wet logs . 👍😎😉

I know right down to pound what I burned it's alot . 306,223,000 BTUs thru boiler. So far divide that in 1/2 thats BTUs to the houses. 6600sqft.
Now what's my heating days .. I will get back to ya .

We could start a list of all the problems for each band 😎👍 my first shot would be centeral boiler . They can't seem to deside if stainless steel is good or bad now it's good lol.. they love selling new ones every 7-8 years lol . Everyone is on to them now so now there making stainless.
Or I could just be a confused consumer.😳😉
