So in-floor is water pipes? I thought it was done by electrical wires. But if pipes are how we'd warm our driveway (if we had one; apartment scum here with a basement garage) then I guess pipes are good inside too.
Do we worry about earthquakes? Would we be better off with radiant in-ceiling heat instead for that?
My farfar was a cabinet maker, my dad was a woodworker, floor layer, tiler, etc, but I'm a nerd and have none of those artisanal skills. This is interesting as heck and it's a connection to my vestigial roots.
