About several months ago, after hours of research, I decided to install 2 small boilers staged and piped to a primary secondary system. The heat loss was calculated at about 400,000 btu.
Well, I recently picked up a 5 year old Buderus G334X for dirt cheap that I plan on replacing with the 25 year old gas fired Weil-McLain that I have so the 2 boiler idea at this point is trashed.
Although I have this one Buderus G334X, I still like the idea of primary secondary piping, I don't know why. The house has 7 zones piped 2 pipe hot water, one of the zones being the kitchen radiant floor.
Its been a while since I researched the P/S piping, can someone tell me how I can benefit from using the primary secondary system with one boiler and if its even necessary. All comments are appreciated.

I like p/s piping so the boiler sees the same flow all the time. The input does not change on this boiler so why should the flow. When one zone calls the boiler is now oversized and the flow can greatly reduce.

Honestly X-tra boilers will only make companies :PTB: one is plenty

At 400,000 BTU and 7 zones 2 boilers makes excellent sense.
May make boiler companies extra bucks, but it'll keep the gas company / oil company in check.
P/S piping will allow proper operation of the boiler with your different heat emitting zones. It will handle the differing water temp requirements much better than any other piping would.
