I’m using a metal wafer pool heat exchange and a boost pump for pressure on the outgoing side.
I have to admit I haven’t thought out whether this will galvanically disappear the copper.
I’ve also thought out putting a 50’ spool of pex inline, but unsure of pressure loss issues. Or maybe that would be good for the house pipes…
