Hello ,
Just wondering if I can use re-circulation pump for DHW to get instant how water on Navien like a CH240, it has a re-circulation built in so could I cause damage if I installed one?

Thank You

    When I do recirc on a tankless taco just renamed there circulation pump it's called genie pump. That will get you the best bang for your dollar. Also what I do is add a air eliminater and a potable expansion tank. I would also make the return 1 inch.
