Description
Underfloor Heating Manifold – Precise Control for Even Heat
Our stainless steel underfloor heating manifold ensures optimal heat distribution in every room. With 2 heating circuits, adjustable flow meters and automatic air vents it enables self-adjusting, energy-efficient heating systems – ideal for residential and commercial applications.
Your Benefits at a Glance
- Precise flow control: Flow meters display the water volume in each heating circuit, easily adjustable with the bleeder key.
- Automatic air venting: Removes air from the pipes, prevents noise, air locks and corrosion.
- Safety mechanisms: Protection against overheating, condensation and overpressure.
- High-quality materials: Manifold bars made of stainless steel WSt-Nr. 1.4301, durable and corrosion-resistant.
- Easy installation: Includes sound-damped mounts, ball valves and Eurocone connections.
- Energy-efficient & maintenance-friendly: Optimized return temperature, system diagnostics and flushing function.

Frequently Asked Questions (FAQ)
What is the purpose of the flow meter?
It shows the water volume per heating circuit so that all rooms become evenly warm.
Why automatic air vents?
Air in the pipes causes cold heating circuits, noise and corrosion. Automatic vents ensure trouble-free operation.
How is the volumetric flow adjusted?
With the bleeder key on the return valve or directly on the flow meter. Target values can be adjusted, typically 2 L/min if unknown.
Safety and maintenance functions:
- System drainage during heating breaks or repairs
- Flushing and diagnosis of deposits
- Temperature monitoring for early fault detection
