I replaced a 55 year old gravity fed boiler. The new boiler works well but I am wondering if I repipe the lines to each radiator if it will help. I have a 2 pipe system, with 12 radiators on 3 runs. I connected the boiler to the existing pipes, which are 2.5" and 3" pipes. If I change the pipes to a smaller size, will the cost be made up in smaller fuel bills and better heat control?
