Look at the "545". The 5 being the first number. The 45 being the second. 5 feet of baseboard. The 45 will tell one to go to the next highest number, which is 6 feet. Again that is the basic formula. Area X btu per hour output of the boiler divided by 3000 ( base number). The base number is always the same. I've used this formula for years and when matched against any other they always come out the same. Thats enough. End of disscussion. LOL
