I am a new user to Hevacomp, and finding it difficult to understand the hot water sizing program. I have entered all my flow pipes to all my fittings after inserting a system marker which checks out that my system is ok, when i opt to size my pipes, no matter what mains pressure i put in up to the maximum 2000 KN/m2 I always get the same error message "Insufficient Pressure at outlet on Floor 1" and the system will not size. What I am doing wrong?
