L=(S/N+Lk×2)×1.1cap L equals open paren cap S / cap N plus cap L k cross 2 close paren cross 1.1 : Room area ( m2m squared N : Laying step (usually 0.1m to 0.2m). Lk : Distance from the manifold to the room entry. 1.1 : A 10% safety margin for bends. On average, expect to use 5–7 meters of pipe per 1 m2m squared of area.

If you prefer to calculate without specialized software, use the standard formula for pipe length ( L=(S/N+Lk×2)×1
