cd is, of course, absolutely correct. When I was helping my brother-in-law build his home, we installed in-floor radiant heating in his basement and the two floors of the house. It's very efficient and super comfortable. The furnace itself is about the size of an average suitcase and hangs on a basement wall. But since he has the three floors separated by thermostatically controlled zones, there is an eight feet wide section of wall which is nothing but copper manifolds, zone valves and a colorful arrangement of tubing.
Other beautiful things about radiant heating is the lack of floor registers, baseboards and cold air returns which tend to dictate the positioning of furniture since they shouldn't be blocked.
What Greenie said is the biggest issue. You wouldn't want to frame up a new wall after installing the radiant tubing. My brother-in-law messed up and started using nails in his hardwood flooring gun which were going straight through the subfloor and endangering the tubes. Luckily, he discovered it before he hit anything and switched out the nails. Ooopsy.
