Ground collector, do you have to change the liquid/hoses?

Hello,

we will then contact an external TGA planner, I'm curious to see what comes of it.

Thank you very much for the information, it was really helpful.

Regards, Andre

Hello,

...we will then turn to an external MEP planner, I'm curious to see what comes out of it.

That will certainly not cause any harm overall, but will be economically helpful!
The planner should have experience with small units (e.g. FFH), be independent, and preferably have construction-related training (e.g. civil engineering)!
Overall, certainly not as convenient as falling for a general contractor/general supplier offer, but very effective in terms of economic efficiency!

Best regards
