Yes the type of boiler gasifier or regular style will dictate the wood usage in the same situation.
I hope to keep a record of what my stove uses this year unlike last year.

i burn between 8 and 12 full cords every year...nothing but dead elm and what ever i pick up off the forest floor getting to them elms. i think i could cut that down some with kickory and ash and oak but i refuse to cut live trees. i know the ash will die soon enough now that we have ash borer in the county

I think I was in the 6 cord neighborhood last winter. My measurement of wood piles was not exact, at least they were exact as i could tell after a 6- pack from the shop ;D

There is a guy near here that burns a whole cord per day all winter. I am not sure what he is heating. I think he has the largest Empyre boiler made and loads it with a skidloader.

Don't know how I missed that model. (7260). That is a monster. Almost 800 gallons of water? 4x more than our 5036. It likes comparing a poodle and St Bernard. Glad I don't have to feed the St Bernard!

It would help a lot to know what kind of boiler you have.  There are huge differences between brands and the efficiency of different models. 

I rarely measure my wood in cords, however I know thats more common in the north, around here we go by the truck load lol. 

Last year I heated 22-2300 sq ft on 9 full truck loads of wood and about 1500 lb of coal.  Coal was experimental.

I just got my CB 6048 running a week ago.  Seems to be doing a really good job so far, but it is not cold yet.  I will be heating about 2500sqft of house plus my DHW, 1000sqft of house to 88F, as well as the 25K gal pool inside it.  I think the pool water uses about 500K BTUs/day based off the propane heater usage last year.

I plan to run the furnace from Oct thru April/May to support the pool water/room mainly.  By then it should be warm enough to use solar supplemented with a little propane/electric.

Any idea on how much wood that would take?  I was thinking 10 cords, or about a cord a month.  Pipes are all insulated and my climate is fair.  It rarely gets below 0F, typically hangs in aroung the 20s for the winter season.

rough guess for thee pool... 1 cord of oak has about 20,000,000 usable btu in it. If we make a guess that your stove is 75% efficient then we can make a judgment call that you can reap 15,000,000 btu from that cord. based on your 500,000 perday pool usage that would be in the area of 30 days per cord for the pool

of course this is just an average from what you say last years usage in propane was, it will go up and down depending on the weather and the type of wood used. also i am guessing at the efficency of your OWB but i thinnk i am in the ball park.. a cb dealer here could maybe be more accurate on your efficiency

an above ground pool will heat easier as it loses heat slower than an inground pool and it takes on heat faster than an in ground pool.

also if you use a solar blanket it will make a huge difference

if the user is correct on the btu they used to heat the pool last year than the btu's will be comparable that i stated. there are charts on the web that will tell you how many useable btu's are in a cord of certain types of wood at the "dry' stage and also if the stove is not a gasifier than the efficiency of the stove could be mush lower than the average i used. it has been said that our old type OWB may be as low as 55% efficient

i know my uncle used to have a pool with a gas heater and he said in the spring it would cost him 3 to4 dollars a day to heat it. i am not sure how many btu that was.

what do you count as a rick? i have read  4x16x8 and i have read 4x24x8 and i have read 4x16x6

you can call it want you want but i think in the usa and canada wood is to be sold compared to a cord stacked 4x4x8 or an equivlent in cubic feet 128

i know here in canada a lot of wood is sold by the "face" cord = 1/3 cord =4'x8'x16" but what ever it is sold as it should easily be able to be compared to a 4x4x8 cord so you know if you are getting ripped or not.

Around here a rick is a face cord 4X8 by about 16 but I cut mine a little longer, about 20 inches.
