Product Information

Heizkreisverteiler als zentrale Komponente im Flächenheizsystem für gleichmäßige Wärmeverteilung bei Fußbodenheizung

Central component of your surface heating system

The manifold is a central component of modern surface heating systems. By ensuring the even and demand-oriented distribution of heating energy to the individual heating circuits, it forms the heart of many floor, wall, or ceiling heating systems. Thanks to its precise control and regulation technology, the manifold enables an exact adjustment of heating output to the specific room requirements. The combination with modern control components such as actuators and room thermostats allows for zoned control, making individual temperature profiles achievable. Our manifolds are made of high-quality, corrosion-resistant materials and are distinguished by their durability, high operational reliability, and easy installation. Combined with suitable accessories and well-thought-out planning, the manifold represents a powerful, low-maintenance, and future-proof solution for all types of surface heating systems.

Heizkreisverteiler mit integrierten automatischen Entlüftern für effiziente Wärmeverteilung, Betriebssicherheit und moderne Heizsysteme

Well-designed construction, integrated safety

Manifolds with integrated automatic air vents offer a reliable solution for the optimization of system performance and operational safety. The built-in quick air vents continuously remove air from the water circuit, entirely without manual intervention. This effectively prevents the formation of corrosion-promoting oxygen, cavitation in the circulation pump, air pockets in the heating circuits, and pump dry running. The result is even heat distribution throughout the system, which not only increases energy efficiency but also significantly reduces disturbing flow noises. Thanks to their compact and low-maintenance design, these manifolds are ideal for modern heating systems where durability, efficiency, and high comfort are key priorities. Automatic air venting thus makes a crucial contribution to the long-term functional reliability of the entire heating system and is therefore indispensable.

Edelstahl Heizkreisverteiler Komplett-Set vormontiert mit optionalem Zubehör für Fußbodenheizung und Flächenheizung

Complete set with optional accessories

Our manifolds are delivered as a practical complete set and offer a reliable solution for modern surface heating systems. The manifolds are made of high-quality 304 stainless steel, are pre-assembled and ready for installation, making them particularly easy and time-saving to install. For even more flexibility and individual comfort, optional accessories are available. These include actuators, which, in combination with room thermostats, enable precise individual room control and thus contribute to an energy-efficient control of the heating circuits. In addition, compression fittings in dimensions 16 x 2.00 mm and 20 x 2.00 mm are available, ensuring a secure and tight connection of the heating pipes to the manifold. With this complete set and the appropriate accessories, you receive a reliable and well-thought-out solution for both new buildings and renovations.

Do you offer customized plate heat exchangers?

Yes, we offer customized plate heat exchangers designed to meet our customers' specific requirements. If you require customized solutions, please contact us with your requirements and we will be happy to help you find the right heat exchanger for your application.

How do you calculate the average temperature difference?

The mean temperature difference of a plate heat exchanger can be calculated by several methods, depending on the type of heat exchanger and the specific conditions. A common method is the Logarithmic Mean Temperature Difference. Here is how you can calculate it:

Formula for the logarithmic mean temperature difference

LMTD = (ΔT1 - ΔT2) / ln(ΔT1 / ΔT2)

variables

  • LMTD: logarithmic mean temperature difference
  • ΔT1: Temperature difference at one end of the heat exchanger
  • ΔT2: Temperature difference at the other end of the heat exchanger

Example

  • Temperature of the hot liquid at the inlet (Th): 150 °C
  • Temperature of the cold liquid at the inlet (Tc): 30 °C
  • Temperature of the hot liquid at the outlet (Th'): 80 °C
  • Temperature of the cold liquid at the outlet (Tc'): 60 °C
1. Calculation of ΔT1 & ΔT2

ΔT1 = Th - Tc = 150 °C - 30 °C = 120 °C

ΔT2 = Th' - Tc' = 80 °C - 60 °C = 20 °C

2. Calculation of the mean temperature difference

LMTD = (120°C - 20°C) / ln(120°C / 20°C)
LMTD ≈ 55.8 °C

How is the heat flow calculated?

Q = U * A * LMTD

  • Q: heat flow (W)
  • U: total heat transfer coefficient (W/m²·K)
  • A: Heat transfer area (m²)
  • LMTD: logarithmic mean temperature difference (K)

or

Q = ṁ * cp * LMTD

  • Q: heat flow (W)
  • ṁ: mass flow rate (kg/s)
  • cp: specific heat capacity (J/kg·K)
  • LMTD: logarithmic mean temperature difference (K)

How should I connect my heat exchanger?

Direct current and countercurrent principle

The transferable heat energy of a plate heat exchanger is determined not only by the size of the exchange surface and the heat transfer coefficient (k), but is also significantly influenced by the flow directions of the media involved. When both media flow in the plate heat exchanger in the same direction, this is referred to as the cocurrent principle. However, if they flow past each other in opposite directions, this is the countercurrent principle.

The flow direction significantly influences the average temperature difference between the media, which is crucial for heat transfer efficiency. Therefore, we strongly recommend the counterflow principle. Connect the plate heat exchanger according to the diagram attached to the heat exchanger.

You can find more information in our blog.

How do I find the right plate heat exchanger application?

Finding the right plate heat exchanger doesn't have to be complicated. If you have any questions or need support, don't hesitate to contact us. We'll be happy to help you choose the right model for your needs.

Are the plate heat exchangers suitable for drinking water?

Our copper-brazed plate heat exchangers are generally suitable for drinking water. However, please note: Particularly soft water (with very low mineral content) or aggressive water (e.g., with very low pH or high oxygen content) can permanently attack the copper brazing.
