Inching closer and closer to going tankless. Have a quote for a Rennai with recirc from a local company where all they do is tankless with Rennai and Navian. Quote is to use cold water line for the return.
I Have a plumber coming out for separate work. Should I have him run a dedicated recirc line with Pex (rest of the house is copper. It I think pex will be easier to run) if I can pull this off with minimal drywall repair? Or just use the cold water return? I don’t want to contaminate my cold water lines with luke warm legionella or something similar if that can happen. But if that is not a concern, warm water for a few seconds until it goes cold is better than cold water for a few minutes before it gets hot.
