Design a 3 story apt building
So I am involved in designing the heating system for a 3 story, 31 apts, a couple other random heating spots in the building, so maybe 40 zones or so. Not a big dealt but was curious what some of you do? They want zone valves for each apt, each apt will have about 16' of baseboard, and I imagine a 3/4" balance setter. The building is roughly 68 x 32, and my plan was to break my header up so each floor would have its own pump, so 4 zones total (basement, first, second, third, hot water) on the header. This would mean smaller pumps and a little simpler to control and troubleshoot. Thoughts?
Also, I finally broke down and bought Siegenthalers design program, I am just waiting for it to get emailed to me, so I can figure up a bit more precisely what the sizing demands will be.
