Zone Valve Placement Guidelines
I am adding zone valves to my forced HW heating system. The existing piping layout is great - it splits immediately after the boiler, with one loop to the living areas and one to the bedrooms.
Question is, what is the best location for the zone valves - in the supply or return lines? Which location reduces the risk of water hammer and other noises? And, if on the supply line, should they be placed as far away from the boiler as possible, or closer to the boiler? Any guidelines would be helpful.

The circulator is on the return, and the expansion tank is on the supply. Then, the 1 1/4" supply splits into two 1" branches.
