Dear Gilles, I have also experienced this problem. I tried to fix it, but it was a very difficult task if you do not know the source code well. I think the problem is related with the way in which the component solves the internal heater, specifically the way in which it tries to adjust its internal time step. I found many convergence problems at this point.
The only practical solution I can tell you is to move away the sensor from the heater, because if they are closed each other, the component is unable to converge to a solution. Place the heater at the bottom of the tank and the sensor at the top, and run a simulation to see if it works. Choose logical control settings. After that, move the heater closer to the sensor until you find problems again. Regards Fernando Dominguez Univ.
