Termojet Distribution Manifolds: From Selection to Installation

A distribution manifold (header) is the component that splits the coolant flow between several independent circuits: radiator, underfloor heating, domestic hot water cylinder. The [pump group](/catalog/nasosni-hrupy) of each circuit connects to the manifold. **Termojet Manifold Variants** The product code indicates the number and direction of branches. For example: - **К22В.125(200)** — 2 circuits, branches upward; **К22Н** — downward; **К22ВН** — up and down. - **К32, К42, К52, К62, К82** — 3, 4, 5, 6, and 8 circuits respectively. - Sizes 125(200) and 150(300) — for different capacities and pipe diameters. When choosing a manifold, count the number of circuits plus allowance for future expansion. **Manifolds with Hydraulic Separator (КГС)** The [КГС](/catalog/kolektory-z-hidrostrilkoyu) series combines a distribution manifold and a hydraulic separator in a single body. This is the most compact solution for a multi-circuit boiler room: it both distributes flow and decouples the circuits from the boiler. Fewer connections means less space required and fewer potential leak points. **BOX Modules** For typical residential buildings there are ready-made [Termojet BOX2 and BOX3](/catalog/termojet-box) modules — a hydraulic separator and manifold for 2 or 3 circuits in a single insulated housing. Connect the boiler and the circuits — the boiler room is ready. **Materials** Steel with thermal insulation — standard for most systems. For underfloor heating, [stainless steel manifolds](/catalog/kolektory-pidloha) with a flow meter on each branch are also used. **Installation** - The manifold is mounted on brackets, horizontally or vertically. - An automatic air vent should ideally be provided on each branch. - Upstream of the manifold in the circuit — a hydraulic separator or КГС, to decouple the circuits from the boiler. A correctly selected manifold is the prerequisite for even heat distribution throughout the building without imbalances between circuits.
