I'm going to be installing cast iron radiators in an addition we're building. 5 rooms in all. Hot water heating, and I'd like to zone the new rooms and the rest of the existing house. How big should I drill holes to run the 3/4" copper tubing? Can anyone recommend a good book on the subject of zoning? Any other advice would be welcome as well, thank you!!
