Manifold Termojet in thermal insulation 3 up + 2 down Mini M51U125(80)

Distribution manifold K51V.125(80) Mini — a compact Termojet header with thermal insulation, featuring 3 outlets up + 2 outlets down for boiler rooms in private homes. Rated at 25 kW at ΔT=10 °C and 50 kW at ΔT=20 °C — the typical output of a boiler or heat pump for a house — while providing as many as five distribution circuits.

The operating principle is standard for a distribution manifold: the heat carrier from the heat source (1″ connection) enters the body and is distributed to circuits with 1″ outlets, to which pump groups are attached. The combined outlet arrangement allows the groups to be placed on two tiers, assembling a multi-circuit boiler room in the minimum wall space. Centre-to-centre spacing of the pipe stubs — 125 mm, the Termojet standard; mounting brackets are included.

Application scenarios: a house with underfloor heating, radiators, a DHW boiler and additional consumers such as ventilation; low-temperature systems with a heat pump where several circuits are fed from a single source — see Termojet heat pumps. For the underfloor heating circuit, install the pump group NG-46 L with thermostatic valve 25–55 °C; if hydraulic separation is also required, consider the manifold with hydraulic separator KGS22V.125(150) Mini.

Advantages of the Mini manifold from Termojet:

• five circuits in a compact body — multi-circuit piping of a small boiler room in a single unit;
• outlets on two tiers — short pipe runs and a tidy boiler room;
• 125 mm standard — compatibility with Termojet 1″ pump groups;
• thermal insulation and brackets included, Ukrainian manufacture, warranty.

Technical specifications: outlets — 3 up + 2 down, capacity 25 kW at ΔT=10 °C and 50 kW at ΔT=20 °C, maximum flow rate 5,1 m³/h, boiler connection — 1″, circuit connections — 1″, centre-to-centre spacing — 125 mm.

More powerful manifolds and versions with different outlet arrangements are available in the Termojet distribution manifold catalogue.

Frequently asked questions

How many circuits can be connected to the Mini?
Five: three outlets up and two down, all — 1″ with 125 mm centre-to-centre spacing for pump groups. Total capacity — up to 50 kW at ΔT=20 °C.

Is a hydraulic separator required?
With several pump circuits — yes: install a hydraulic separator upstream of the manifold or choose the KGS Mini series with an already built-in hydraulic separator.
