Welcome! Here are the website rules, as well as some tips for using this forum.
I've been reading on primary and secondary piping systems from Dan's book. As I start to put the puzzle together I was wondering if you could possiably make a recomendation on where I could purchase the controls needed for these type of systems. I live in Nassau and I'm not sure my supply House would be able to sell me the proper controls.
Thanking you in advance,
PS, also enjoyed your book on Quick and Basic Hydronic Controls, thanks
