Hydraulic balancing for underfloor heating

Hydraulic balancing of the underfloor heating system ensures that all rooms in the building are evenly supplied with heat. Especially in multi-family houses, hydraulic balancing is an economic and ecological necessity that is also required in relevant DIN standards and regulations.

More even and faster heating, noticeable energy savings, the avoidance of flow noise at the manifold, and greater comfort through optimum heat dissipation are the best arguments for hydraulic balancing to be carried out professionally.

x-net A/E valve for underfloor heating manifold

Kermi x-net A/E valve for underfloor heating manifold

The Kermi x-net A/E valve designed to be connected to the x-net manifold helps you precisely and quickly perform hydraulic balancing for different applications.

Application

The x-net A/E valve for underfloor heating manifolds is used as a line regulator valve for precise and quick hydraulic balancing of heating systems by manually setting the maximum flow rate per x-net manifold. The adjustment range is 4–36 l/min.

Highly  recommended

for the following application

  • Hydraulic balancing of manifolds  with each other in a line
  • Reduction of flow noises  from manifold

for building projects

  • Multi-family house  New-build
  • Multi-family house Refurbishment

x-net heat flowmeter installation sets AB-PM horizontal and vertical

Kermi x-net heat flowmeter installation set AB-PM 5/4" horizontal

The x-net heat flowmeter installation set AB-PM for installation directly before the manifold allows quick, uncomplicated installation for volume flow limitation, independently of the differential pressure.

Application

The x-net heat flowmeter installation sets AB-PM horizontal and vertical in the respective standard sizes DN 20 and DN 25 are designed for use in heating applications in residential buildings. The integrated automatic combination valve is a differential pressure regulator with flow limitation, offering the three functions of differential pressure control, flow limitation, and control valve with linear characteristic in one valve housing. The existing fitting pieces with an installation length of 110 mm (version DN 20) and 110 mm or 130 mm (version DN 25) make sure it is easy to install heat flowmeters.

Highly  recommended

for the following application

  • Hydraulic balancing of manifolds  with each other in a line
  • For the installation of a commercially available  heat flowmeter
  • Reduction of flow noises  from manifold

for building projects

  • Multi-family house  New-build
  • Multi-family house Refurbishment

x-net manifold D

Kermi x-net manifold 5/4" D

The x-net manifold D is a specially designed, new x-net heating circuit manifold. An automatic flow controller is already integrated as standard for each heating circuit in the return line.

Application

The x-net manifold D with the automatic flow regulators integrated in the return line for each heating circuit keeps the set flow rates constant, regardless of pressure fluctuations in the pipe system. The range of adjustment per heating circuit is 30–300 l/h.

Highly recommended

for the following application

  • Hydraulic balancing of heating circuits with each other at underfloor heating manifold

for building projects

  • Multi-family house Refurbishment
  • 1–2 family house Refurbishment

x-net overflow device

Kermi x-net overflow device

The x-net overflow device is mounted as bypass section at the end of the manifold to reduce flow noise and to ensure a minimum flow rate.

Application

To avoid/reduce annoying flow noises from the x-net underfloor heating manifolds if the circulation pump is overloaded by closed actuators and to ensure a minimum flow rate through the manifold.

Highly recommended

for the following application

  • Reduction of flow noises from manifold

for building projects

  • Multi-family house Refurbishment
  • 1–2 family house Refurbishment
