Hey DIY comrades, I was encouraged to post this here instead.

As the title suggests, I’m building a garage pad and basement and I am planning to do radiant floor heating so I can transition to geothermal heating in a year or two. However I don’t like the idea of plastic pipes in the system as plastic leeches into water, and especially hot water. Is there a non plastic option? I’ve read it’s possible to do copper but that it has to be sleeved and with the price of copper it’ll be very expensive. Or does it really matter if it’s a closed loop system? What are my options? Thanks guys!
