I am curently a second year student studying computing A level, for my final project i am programming a central heating heat loss calculator which calculates what size radiator you need. I need to find information on how the analouge calculators work and also need to find out out about the maths they use. Any help you can give on this topic will be greatly appreciated.
You will find the information you need under Heat Estimate Calculation at the site http://www.hydronic.net You will find the program you are going to make and the formulas for doing the same.
