LINEAR ANALYSE DISTRICT HEATING

DIGITAL TOOLS FOR THE HEAT TRANSITION: PLANNING DISTRICT HEAT NETWORKS WITH LINEAR.

Municipal heat planning is becoming increasingly important. Efficient, cost-effective, and sustainable district heating networks play a key role in this – but they present planners with complex challenges. With LINEAR, you have access to a software solution that integrates every step of the planning process: from the initial design to the final implementation phase.

Municipal heating planning will generate a multitude of new projects in the coming years. Those who enter the district heating planning sector now will secure full order books and a clear competitive advantage.

If you are interested, we look forward to hearing from you.

 

 

 

 

 

 

 

 

 

 

HOLISTIC PLANNING
Planning district heating networks is a complex process. Until now, planners have often had to rely on various standalone solutions that cover only specific aspects.

With LINEAR, you now have access to the first end-to-end software solution that integrates every step from the initial sketch to the final, implementation-ready design. Developed in collaboration with REHAU, we draw on extensive project experience.

PRECISE HYDRAULIC CALCULATIONS
Large, branched networks with various consumers and heat sources place enormous demands on hydraulic calculations.

With LINEAR, you can view, calculate, and optimize even complex networks holistically – in accordance with recognized principles such as Kirchhoff’s laws and relevant standards. This provides planning reliability and expands your options.

MATERIAL CALCULATION AND OPTIMIZATION
Long pipe runs, expensive materials, and high installation costs create an economic challenge that consumes significant resources.

With LINEAR, you can optimize your networks so that material usage and installation costs are precisely balanced. Every dimension saved represents a significant cost reduction while conserving resources.

DEVELOPED IN COLLABORATION WITH

The software is designed for the technical planning of municipal district heating networks—specifically for the phase in which a network concept is transformed into a calculable, implementation-ready CAD model. A key benefit is the combination of CAD-based modeling and reliable network calculations based on proven rules and planning logic, which were incorporated into the development through the collaboration between LINEAR and REHAU. This creates a seamless workflow from route planning to material determination and the generation of construction-ready plans. REHAU contributes, in particular, the perspective gained from real-world projects as well as its system and material expertise in polymer-based local heating systems – with the goal of ensuring that calculations and implementation align consistently within the model.

REHAU Pipe Systems for Municipal (District) Heating Networks

To accelerate network expansion, REHAU has developed the universal district heating pipe RAUVIPEX. The versatile RAUVIPEX is suitable for connecting heat pumps to individual buildings, but is particularly well-suited for heat transport within a heating network. It can be installed quickly and flexibly, is available in a wide range of sizes (d20 to d140), and offers long-term reliability. The pipe is also suitable for cooling applications and can therefore be used as an all-rounder in many projects. 

RAUVIPEX is also an ideal complement to the established RAUTHERMEX composite pipe system, which was designed for use in local and district heating networks with the highest thermal insulation requirements. The special polyurethane foam insulation in RAUTHERMEX reduces heat loss to a minimum and is additionally available with increased insulation thicknesses (Plus dimensions). 

At the heart of both pipe systems are durable PE-Xa medium pipes. The pipes are connected using the sliding sleeve press system without O-rings and without welded seams.

CLIP-FLEX Sleeve with Integrated Sealing System 

The REHAU CLIP-FLEX coupling is the strong connecting element at pipe joints and branches and ensures professional retrofit insulation. The coupling is universal, flexible, and proven to be leak-tight. The product is available in T, I, and L versions and fits all REHAU local heating pipes with diameters ranging from 90 to 250 mm.
