HERZ stainless steel manifolds are designed for use in underfloor, wall, and ceiling heating and cooling systems. They are used in combination with HERZ shut-off or ball valves for optimal system performance. The compact design allows easy installation in distribution cabinets or directly on the wall. Integrated air vent and drain valves enable quick venting and system drainage.

The manifolds are compatible with other HERZ components, allowing flexible system planning. Various models are available with different numbers of heating circuits. High-quality materials ensure long service life and resistance to corrosion.

Declaration of conformity - SLO, ENG, DEU

Material:
The manifolds are made of high-quality stainless steel X5 CrNi 18-10, ensuring excellent corrosion resistance and long service life. Other components, such as shut-off and thermostatic valves, are made of brass according to EN 12164.

Operating Conditions:

Maximum operating pressure (without flow meter): 10 bar
Test pressure: 10 bar at 20 °C
Maximum allowable temperature (without flow meter): 110 °C
Minimum operating temperature: 2 °C

Medium:
The manifolds are suitable for use with heating water in compliance with ÖNORM H5195 and VDI 2035 standards. The use of ethylene or propylene glycol in a 25–50 % mixing ratio is allowed, following the manufacturer’s recommendations. EPDM seals are not resistant to mineral oils, so their use in such systems is limited.

Connections:

Manifold inlet: internal thread G1˝ (ISO 228-1)
Heating circuit outlets: external thread G3/4˝ with cone sealing
Number of heating circuits: from 2 to 12 (up to 16, depending on the model)

Integrated Components:

Shut-off valves on the supply side (depending on the model)
Thermostatic valves on the return side (depending on the model)
Air vent valves for air removal from the system
Drain valves G1/2˝ for system drainage
Mounting brackets for wall or distribution cabinet installation

Compatibility:
The manifolds are compatible with all HERZ components, including HERZ PIPEFIX adapters, shut-off, and ball valves. We recommend using HERZ shut-off valves for optimal system performance.

HERZ floor heating manifolds allow quick and easy installation in a distribution cabinet or directly on the wall. The integrated brackets ensure stable attachment and flexible mounting positioning.

All connection threads must be sealed with appropriate seals to prevent leaks. When connecting pipes, the use of HERZ PIPEFIX adapters is recommended for easy installation. After installation, it is necessary to check the proper operation of all valves and air vents. Maintenance includes regular inspection of valve functionality and removal of any impurities.
