Selection Points: For underfloor heating systems, prioritize 316 stainless steel; 304 is an option if budget is limited.
The number of branches must match actual needs to avoid uneven water distribution due to insufficient branches.
Installation Specifications: A pressure gauge and air vent must be installed to ensure system stability.
A straight pipe section of at least 30cm must be maintained between the main pipe and the manifold inlet (according to the "Technical Specification for Radiant Heating and Cooling" JGJ 142).
