manifold Termojet with flow meters for 5 outlets, stainless steel

The Termojet 5-outlet manifold with flow meters is the central distribution unit of an underfloor heating system for houses and apartments with five independent circuits. Stainless steel AISI 304, built-in flow meters 0–5 l/min on each circuit and standard connections G 1" / G 3/4" Eurocone provide precise hydraulic balancing without additional tools. Compatible with a heat pump: low-temperature mode 30–45°C is fully within the manifold's operating range.

Technical Specifications

Operating Principle and Balancing

The manifold distributes the heat carrier simultaneously across five underfloor circuits. Each loop has its own length — and therefore its own hydraulic resistance: a longer loop passes less heat carrier without balancing. The flow meter with a transparent cap and float indicator allows visual monitoring of flow on each circuit in l/min and adjustment of the return manifold valve to the required value. The result is uniform floor heating in every room without overheated or cold zones.

Application Scenarios

• A house with 5 rooms (different areas, different loop lengths). Flow meters allow each circuit to be balanced individually — this cannot be achieved with shut-off valves without measurement.
• An apartment with underfloor heating in the bathroom, kitchen and three rooms. The compact length of 330 mm fits a standard cabinet No. 01.
• Zone control. M30×1,5 actuator sockets allow an actuator to be installed on each circuit and implement per-circuit control from room thermostats.
• Heat pump system. A low supply temperature of 35–40°C is the standard operating mode for the manifold.

Advantages

• Stainless steel AISI 304 — does not corrode even when using glycol heat carrier; durability on par with leading European manifolds.
• Flow meters 0–5 l/min on each circuit — precise flow-based balancing, as in premium series.
• M30×1,5 sockets — industry standard: compatible with mass-market actuators without adapters.
• G 3/4" Eurocone (DIN EN 16313) — connection of PE-RT 16×2 pipe via a standard fitting Eurocone 16×2 without special tools.
• Complete set — valves with thermometers, air vents and drain valves are already included.

Underfloor Heating and Heat Pump

An air-to-water heat pump achieves COP 4–5 at a heat carrier temperature of 35–40°C. Underfloor heating is the only heating system that effectively uses this low-temperature mode: radiators require 55–70°C and reduce COP by 30–50%. The Termojet 5-outlet manifold is designed to operate in this mode with a twofold safety margin on pressure and temperature. More about integrated solutions — on the Termojet heat pumps website.

Frequently Asked Questions

What is the difference between a manifold with flow meters and one with valves?
A manifold with valves only allows a circuit to be closed or fully opened. The 5-outlet manifold with valves is suitable for simple systems with equal loops. A flow meter shows the actual flow in l/min and allows precise balancing of each loop regardless of its length — this is a fundamental difference in houses with rooms of different sizes.

Which cabinet is suitable for a 5-outlet manifold?
We recommend manifold cabinet No. 01 (435×575×110 mm) for recessed installation. If installation of a mixing unit for the manifold is planned — choose cabinet No. 02 with greater width or install the unit separately.
