manifold Termojet with valves for 10 outlets, stainless steel

The Termojet TJ-R-W manifold with 10 outlets — a distribution unit for underfloor heating systems in large buildings with ball shut-off valves on each of the ten circuits. Stainless steel AISI 304, wall thickness 1,6 mm, DN40 profile. Main connection — G 1", circuits — G 3/4" Eurocone. Unit length — 580 mm. The solution for systems requiring the ability to isolate each zone without the need for precise hydraulic balancing.

Technical Specifications

Operating Principle

The TJ-R-W-10 manifold receives the heat carrier through the G 1" inlet and directs it through 10 independent underfloor heating circuits. The ball valve on each outlet opens or closes with a 90° handle rotation. This allows complete isolation of any circuit — for example, closing the zone in an empty room or disconnecting a damaged loop for repair without stopping the rest of the system. On the return manifold — M30×1.5 sockets for actuators: connection of room thermostats and zone temperature control is available without replacing the manifold.

Where It Is Used

• Large house with uniform layout. 10 rooms with approximately equal area and loop lengths — the system operates without the need for precise balancing. Shut-off valves allow zone control.
• Commercial premises. Offices, shops — where the ability to quickly shut off a section without stopping the facility is important.
• Cost-effective project for a large house. Stainless steel AISI 304 is identical to the flow meter version, but at a lower price — when balancing is achieved at the design level with equal loop lengths.
• System with a heat pump. Low-temperature heat carrier 35–45°C, 10 circuits load the pump evenly — stable and efficient operation.

Advantages

• Stainless steel AISI 304 — the same material as in the premium series with flow meters. Corrosion resistance, durability, glycol compatibility.
• 10 shut-off valves — independent control of each circuit, repair without draining the system.
• G 3/4" Eurocone — direct connection of PE-RT 16×2 pipe without adapters.
• M30×1.5 sockets on the return manifold — compatibility with mass-market actuators.
• Lower price than the flow meter version — sensible savings for systems with equal circuits.

Underfloor Heating and Heat Pump

Ten underfloor heating circuits — the optimal load for a heat pump operating at 35–40°C. The stainless steel AISI 304 of the TJ-R-W-10 manifold is resistant to glycol heat carriers and long-term operation in low-temperature systems. To maximize pump COP, complement the system with a mixing unit for the manifold. Learn more at Termojet heat pumps.

Frequently Asked Questions

Ball valve version or flow meter version — which to choose for 10 circuits?
If the loops are of different lengths or the rooms have different heat loads — choose the 10-outlet manifold with flow meters: precise balancing will ensure uniform heating of the entire house. The manifold with ball valves is suitable when all loops are approximately equal or the project involves uniform zones.

Which cabinet suits a 10-outlet manifold?
Manifold cabinet No. 03 for 8–10 outlets, 715×575×110 mm — the optimal choice. The full range of cabinets and manifolds is available in the Termojet underfloor heating system catalogue.
