Emphasis is not only put on efficiency, but also on operational reliability:

The burner will automatically switch off, should the maximum admissible thermal oil outlet
   temperature or the maximum admissible flue-gas temperature after the heater be exceeded

In order to protect the thermal oil, the burner capacity is reduced during cold start until the
   minimum temperature is exceeded. Following that, capacity output of the burner is increased
   until reaching the setpoint value

The burner shuts down immediately if the pump stops running

To avoid over heating and thus damaging of the thermal oil, a minimum volume of the oil
   must always flow through the heater. A flow control device approved for this type of installation
   controls the minimum oil flow through every single pipe coil

The filling level of the thermal oil in the expansion tank is monitored by a type examination
   tested float switch. If the filling level is too low, the plant will switch off

If the plant is shut down, the circulation pump is operated for a certain period of time to
   carry away heat that may have accumulated

In order to achieve high safety standards, INTEC thermal oil systems comply with the regulations of the German Industrial Norm DIN 4754.
