Subject: thermic bypass and other questions

Are thermic bypass valves always included in boilers systems manifolds or just when using condensing cast iron boilers? Hi, I am designing a 5 zone system w/3zone infloor, fan watercoil, indirect DHW, on a new Buderus 125kbtu boiler w/ Logistics control brain. Am gettin conflicting advice on whether to use mixing valves to each infloor zone, whether to use individual circs or 1 main circ & 1 circ plus individual zone valves and just how to prioritize the DHW. Any input to shed more lite on the subject? Plus it all needs to come together on the wall like a work of art(demanding client even painted the wall for mounting all the manifold systems) STormin
