Efficiency is the key to direct transmission:

In the last 20 years the understanding of the users of temperature control units and the handling of the units, as well as the water quality used, has changed significantly. With this understanding, higher quality stainless steel materials and innovative design solutions such as solid state relays, multiple safety circuitry and guided flow, the failure rate of direct heat transfer when using heater cartridges has been reduced to a minimum.

Due to the significantly improved heat transfer and thus higher efficiency compared to indirect heating, this method is still the preferred method at gwk.

In this context, the efficiency and reliability speaks a clear language.
