Manifold Termojet with valves for 5 outlets, stainless steel

Termojet 5-outlet manifold with ball valves — a solution for underfloor heating systems where the primary task is to reliably open or shut off each floor circuit individually. Stainless steel AISI 304 body (wall thickness 1.6 mm), shut-off valves on each of the five outlets, main connection G 1", outlets — G 3/4" Eurocone, spacing 50 mm. Manifold length — 330 mm. Maximum pressure 10 bar, maximum temperature 110°C.

Technical Specifications

Operating Principle

The manifold distributes heat transfer fluid from the main pipe across five independent floor loops. The ball valve on each circuit allows you to quickly open or fully shut off any loop — for example, during repairs in a separate room or to isolate a rarely used zone. The M30×1.5 sockets in the body allow thermal actuators to be installed at any time for zone automatic control without replacing the manifold.

Application Scenarios

• Apartment or small house with loops of equal length. When the difference between circuits is minimal — shut-off valves are sufficient, hydraulic balancing is not critical.
• Budget system for future expansion. The manifold with valves is less expensive; M30×1.5 actuators and flow meters can be added later without replacing the main unit.
• Heat pump system with equal circuits. When designing loops of equal length and equal room area, balancing is not required — the valves provide all necessary control.
• Emergency zone isolation. A leak or repair in one room — the valve is closed in a second, the rest of the system continues to operate.

Advantages

• Stainless steel AISI 304 — the same material as in the premium series; no corrosion or deposits even after 10–15 years of operation.
• Ball valves — full opening or closing with a quarter-turn of the handle; reliable sealing without leaks.
• M30×1.5 — industry standard: thermal actuators for zone automatic control can easily be added in the future.
• G 3/4" Eurocone — connection of PE-RT 16×2 pipe via Eurocone 16×2 fitting; no soldering or welding.
• Affordable price — savings compared to the flow meter version; suitable where precise balancing is not required.

Underfloor Heating and Heat Pump

The heat pump provides heat transfer fluid at 35–45°C — well within the manifold's operating range (max. 110°C). When designing loops of equal length for a heat pump, the 5-outlet manifold with valves is a sufficient solution without additional balancing. If loops have different lengths — consider the 5-outlet manifold with flow meters for precise balancing. Learn more about heating systems with a heat pump on the Termojet heat pumps website.

Frequently Asked Questions

When to choose a manifold with valves and when — with flow meters?
A manifold with valves is suitable for systems with equal loops (length difference up to 10–15%) or when only the ability to isolate a zone is needed. The 5-outlet manifold with flow meters is necessary where loops have different lengths — it allows measuring and adjusting the flow rate on each circuit. If in doubt — choose the flow meter version: the price difference is small, and balancing is greatly simplified.

Can thermal actuators be added to the valve manifold?
Yes. M30×1.5 sockets are present in the manifold body — standard thermal actuators are installed on them without any modifications. A mixing unit with a bypass valve is also required to protect the pump when actuators are closed.
