Help with Vitodens piping

Unknown
Unknown
in THE MAIN WALL
This drawing is based upon Viessmann’s suggested layout for the Vitodens. I’ve made only minor adjustments. I’m looking for any defects in this rather simple design. The drawing is unfinished and I would like your input as to how I may improve and simplify the near boiler piping.

I’m unsure if the Spirovent should be placed where I currently have it located. The Vitodens has it’s own air eliminator.

Please share your thoughts

    why 4 high temp pumps? you can only set the curve for 1 high temp pump so usually I size for 1 pump, sized for the entire zone. Additional pumps(ie: HX;HW Air Coil,etc) can be used, and controlled by a separate relay(s), but proper design may eliminate the additional pumps. Also, no need for a Spirovent after the LLH, as long as yuou have puirge valves.
