There is a heat register in there, too.
What temperature is yours running at? Do you keep it on all the time?
My concern is that I can only feel a tiny bit of warmth and it never shuts off, keeps running and seems to top out at 17.5 degrees.

Depending on the thermostat, some floor heating systems have max temp limits that are low (like 20 degrees, not 17) as they can be installed directly over wood subfloors. That said, 17 is extremely low so probably not cutoff related.
Couple thoughts:
- How have you confirmed it is running all the time when it holds at 17.5? Possibility it isn't running all the time?
- If it is indeed running all the time and capping out at 17.5, its either woefully undersized or indeed heating the slab and earth below it. A thermal break (like subfloor panels or the insulated tile membranes like insulated-Ditra) is probably what should have been installed ideally, but it could just be a case that the slab/earth is still acting like a heat sink and eventually it will get to a saturation point. Hopefully then some more of the heat will remain in the tile/room.
