    Too many variables.

    I wouldn't use it.

    Confused

    There is no magic formula for all installations. There are way too many variables involved. If you have used load calcs in the past, I would suggest doing so in the future.

    You stand across the street and put your hand in front of the house. The number of fingers it takes to cover the house is the number of burners the furnace needs.

    You said that way has worked well for you.
    I guess that means you have never been undersized.
    But, how do you know your not oversized by 30, or 40%?

    Hmm The Easy Way

    Just ask your supply house guy "Hey I got a 2000 Sq Ft house. What size do I need?" And they will hook up!
    Yes sir! its on the truck.

    Also works for boilers, 1 section for each finger.

    If he was doing my house I would have a finger for him.
    Karst means cave. So, I search for caves.
