    Heat can be conducted to the post-heating radiator of DIGIT2 SE VKL in other ways than described above. It is possible to build a separate circuit for the radiator if higher power is desired, or the risk of freezing can be eliminated by using non-freezing heat transfer solution. For more information, see the instructions for VALLOX VKL connections.
