: What is the formula to determine the correct amount of radiation for each room? Whats the best type of radiation; whats a good boiler? : Any advice for installing the system myself would be appreciated. there is no real formula you need to have someone do a heat/loss caculation done on entire house consisting of square footage window sizes and type of, single pane, thermopane . wall thickness and type of insulation. attic insulation. and the mean ambiant temp. of your area. all this is required to size everything baseboard and boiler. remember once it,s installed it,s nice to have it all work properly and comfortable for years to come. if not sure of what to do have a pro. look at it.(sorry im to far away) good luck stay warm.
