Hi All,
I want to have installed in my basement an additional zone of hot water baseboard heat. The basement has a concrete slab floor. A plumbing contractor told me the level of the copper pipe used to connect the baseboard should remain mostly level, and is suggesting in one instance channeling into the concrete floor to continue the loop, as opposed to going up, over and down an obstacle with the pipe. He said this will prevent excess air in the pipe and avoid the constant need to bleed the pipes. I'm not keen on the idea of laying copper pipe into concrete. Is keeping the pipe level really a big concern in this kind of application. Thanks for advise in advance.
