Note
For a heating water buffer cylinder, heating circuit with mixer, external
heat source (gas/oil/wood), etc., additional supply and control cables
and sensor leads must be factored in.
Check the core cross-section of the power cables and enlarge if
required.
Cable lengths inside the internal/external unit plus wall clearance:
