It calculates how much wood would be needed to ENTIRELY heat your home for a whole winter! It even calculates how long it would take for the JUCA to PAY FOR ITSELF! (It estimates how much you are likely to save in conventional heating fuel, and it knows the total installed cost of the JUCA installation which it recommends.)
All of the information it generates is UNIQUE for YOUR INSTALLATION! Where else could you get all this personalized info? A competing dealer or salesperson is not likely to have the engineering background to do a Heat Loss Analysis for your house! Cool, huh?!
