Good day. I would be interested to know which types of circulation pipe systems exist in apartment buildings. As far as I have already informed myself here, in the new construction of an apartment building (3 floors), a circulation pipe system must be installed. However, is there a "simple, cost-effective" variant and a "comfortable" variant? What is the difference? Are there regulations regarding which system must be installed? Thank you very much.
