Thanks for the clarification craig.Webmaster said:Here is what you do with those multipliers....
that figure x the number of BTUs in the UNIT on the compare page =1 million BTU of heat input.
So the value for Gas, which is 10 is multiplied by THERM (the unit on the calc page) to equal 1 million BTU
The value for Pellets, .062, must be multiplied against the BTU in a TON of Pellets (again the unit on the calc page) to equal one million BTU. So if a ton has 2000 (lb) times 8,000 BTU/LB that is 16,000,000 BTU x .062 which equals a million BTU.
So, in this way, those figures can be checked for accuracy against what one thinks the fuel value should be.
So those are my fuel BTU assumptions.....
The chart allows for the user to adjust effic. and price, so those are variables, but the BTU values are hard-coded in.
I came up with those #s too on page 7, just using my bassakwards way of doing things.
That 5600 BTU I went back and checked I figured that at 70% oops..
Where were you 4 pages ago.....
But in my checking I think that my conclusion on this whole thing was that the #s should be alittle bit lower for hardwood.....
After all is the calculator for people looking to get off of fossil fuels or for the hardcore wood guy's that know that orange ossage is about 30mil BTU's
Be right back with an edit....
