Another quick update: The system is up and running, and working well for the past 5 weeks or so. We've had one unusually cold period (28F for a few hours one night), at which the system had a little trouble keeping interior temperatures at the target 71 degrees, but I'm confident that problem will disappear once I've got insulation between my floor joists - as it stands, I've definitely got a higher R value on top of my heating loops than below, which of course can't be good.
Other than that, the heat is very comfortable and the natural gas usage seems to be only about half what it was with the forced air, based on preliminary usage data from PG&E. I'm looking forward to getting the crawlspace insulated to bring the system up to its true potential
