In response to Re: hot water gravity recirculation
Where you run it to is less important than how you run it, and how the existing piping is arranged. Unless the piping has a constant upward slope away from the water heater, (i.e., no drops to get under beams), and the pipe back to the water heater can be installed with a continuous slope down to the heater, the system will not work.

: I want to install a gravity recirculation system for hot water. What is the best diameter tubing to use? Can I use plastic tubing? Is it likely to be successful running from basement to second floor? Any tips?
