The manifold is coupled with flow and return thermometers. An automatic air release and drain valve is included on the manifold. A clamp set is included. This underfloor heating manifold set is made of 304 stainless steel. Thanks to flowmeters and valve groups, the water flow of each line can be adjusted separately, thus ensuring a more balanced and efficient heat distribution in the system. Underfloor heating manifold sets can be produced in different combinations from 2 outlets to 15 outlets. Manifolds with mini valves are also manufactured. What is a manifold? What is its purpose? It distributes and collects water coming from a main line to multiple pipes. We can call it the distribution center of underfloor heating. The manifold consists of two main parts: Upper and Lower Manifold. Upper Manifold; This is the supply line. Hot water comes out from here. It distributes it separately to each room. It has flow rate adjustment indicators (flowmeters). Lower Manifold; This is the return line. The cooled water comes here. The boiler rotates to be reheated. It has valves or thermostatic control elements. This is a clamp set that connects the upper and lower collectors.
