Attaching walls to floor with in-floor hot water heating tubes

Our basement has in-floor hot water heating tubes, so we don't want to drive nails into the concrete. How should we attach the soleplate of our walls? Adhesive?

Also, does anyone know about the heating effectiveness when putting floor coverings (carpet, etc) over the concrete floor with heating tubes?

There are devices that can be used to detect running water. Perhaps see if a local plumber can map out the area or using a stethescope, you may be able to figure it out for yourself, but a miscalculation can cause a real nightmare. If you are just framing around the walls, you can leave the bottom plate unattached to the slab and install cleats on the block or pourd wall near the bottom of the studs to anchor the walls to the floor by attaching the studs to the cleats, either 2x4's flat agaisnt the wall or stimpson ties. For walls that go across the floor, have it mapped out or use the stethescope approach. Less scientific would be if the heating has not been run for a while, turn it on and feel fro temperature variations. Heat wil rise up through the slab quicker than it will migrate horizontally through the slab. If the heat has been running for a while, it will probably take a while for such a thermal mass to cool off.

Most houses around here that utilize radiant floor heat in a slab the tubes are at least 2" below the concrete surface, so we have always just set our hammer drill to bore a hole 1" deep and get the appropriate length Tapcon screws to secure the bottom plate to the slab. Here we must have it secured every 24" so by the time you get a run of a wall with screws protruding into the slab 1" deep there is no way that wall will ever shift/move.

Turn up the heat and mop the floor. The areas that dry first are where the heating lines are. Before the surrounding areas dry mark the dry ones with chalk. You can nail between the heat lines. If you plan on installing floorcovering mark it with permanent marker.

In floor heating systems work well with carpet and give an unexpected warmth to a ceramic tile floor.
