correct sizing methods

There are 3 methods for figuring boiler size. 1st method is the finger method,you stand across the street hold your hand in front of your, face however many fingers it takes to block out the house thats how many sections you need.Now if your still not sure you use the looksalotlike method [no explanation needed].When all else fails you use the swag method which is scientific wild **** guess.Any other methods out there i would enjoy hearing

Another method that Dan mentioned a few years ago in an article is to determine the size of the existing boiler and increase by one size. You'll never get a call back for insufficient heat.

You could just use the same size that the neighbor has.
