Manifold Termojet in thermal insulation 2 + 1 up Mini M22U125(150)

Manifold K22V.125(150) Mini — a compact Termojet distribution unit in thermal insulation for small boiler rooms: two main upward outlets for pump groups and one side outlet G½″, boiler and circuit connection — 1″. Power up to 25 kW at ΔT=10 °C and up to 50 kW at ΔT=20 °C — ideal for a boiler serving a house of up to 200 m².

The Mini manifold is structurally a dual header of minimum dimensions: the supply and return lines in one housing, two main outlets with a centre-to-centre distance of 125 mm for Termojet pump groups and one additional G½″ outlet. The outlets face upward — convenient when pump groups and pipework runs pass above the manifold. Wall-mounting brackets are included.

Typical scenarios for Mini 2+1: two main circuits (underfloor heating and radiators) plus one small outlet for a DHW boiler or sensor. Does not take up much wall space in the boiler room, which is important in built-in boiler rooms and utility rooms. Mounted on the outlets are the pump group NG-46 with thermostatic valve (underfloor heating) or the direct NG-47 without mixer (radiators, DHW). If hydraulic separation is required — paired with a hydraulic separator or as a manifold with a built-in separator, consider the KGS22V.125(150) Mini with hydraulic separator.

Advantages of Termojet K22V Mini:

• compact form factor — fits even in a small built-in boiler room;
• 125 mm standard — full compatibility with Termojet 1″ pump groups without adapters;
• thermal insulation jacket and brackets included — installation at no extra cost;
• Ukrainian manufacturing, affordable price, official manufacturer's warranty.

Technical specifications: outlets — 2+1 upward, boiler and circuit connection — 1″, additional connection — G½″, maximum power 25 kW at ΔT=10 °C and 50 kW at ΔT=20 °C, maximum flow rate 2.1 m³/h, centre-to-centre distance — 125 mm. Other configurations — in the Termojet distribution manifold catalogue.

Frequently asked questions

What is the difference between Mini and the standard manifold K22V.125(200)?
A smaller housing volume and lower maximum flow rate: Gmax here is 2.1 m³/h versus 7.2 m³/h in the standard model. Mini is suitable for systems with small pump groups and boilers up to 50 kW; for more powerful systems, choose the standard K22V.125(200).

Is a hydraulic separator needed with the Mini manifold?
If both circuits have their own pumps — yes, a hydraulic separator is required. If you want to save space, consider the KGS22V.125(150) Mini with a built-in separator.
