I have a Kerr TW2000 connected to my oil boiler in an in-series arrangement as shown in the attached diagram. The boilers heat three floors with a combination of cast iron and baseboard heaters. The house is about 2700 sq/ft , counting the basement. I ran this setup last winter and used (estimate) between 10- 11 cord.
I have always read that the parallel piping setup is more efficient in that it doesn't heat the other boiler and you do not lose heat up the chimney. The current in-series setup worked fine last year, my only complaint could be the amount of wood burned. If I were to go through the troubel of re-piping it to a parallel setup, would I potentially burn less wood?
If Yes, what would be the easiest way to change the existng piping, based on the diagram below?
Thanks
