I have a separate zone in my attic that was installed for future use on my hydronic system. Two 3/4" copper pipes, 1 send & 1 return connected together.
The future is now and I have opted for a Turbonics recessed heater (basically a toe kick in a cabinet). I have a couple of questions
Do I still need a mono flow tee on the return even though I have separate pipes going in and out? If I don't can I add an additional unit further down stream later without a mono flow tee on the return ?
