4 Hevacomp Alternatives in 2026

Numerous design and calculation programs offer engineers compliance, efficiency and collaboration.

Among these is Bentley System’s Hevacomp, which allows users to design system layouts and receive results through automated calculations.

Hevacomp’s modelling software simplifies processes to unlock a range of desirable benefits, including:

• Efficiency: The software handles tedious work like measuring lines and counting fixtures
• Extensive results: Hevacomp provides accurate flow rate calculations, pipe sizes, velocities, and pressures for engineers

 

Despite Hevacomp’s great features, users have noted some deficiencies, such as:

• The tool is slow to input the relevant data
• Requiring workarounds for flow rate calculations where there are below 300LU
• A lack of updates means the usefulness of the software is diminishing
• Hevacomp’s pricing targets primarily medium-sized and enterprise businesses

 

Due to the deficiencies noted above, Bentley Systems discontinued Hevacomp on 1st January, 2026, and replaced it with OpenBuildings.

The good news is that other solutions are available, whether you’re looking for a tool that’s easy to use, offers value for money, or has a good user rating.

Today we will examine the best Hevacomp alternatives currently available to engineers. So, let’s get started.

#1 h2x

h2x was created by engineers that were frustrated with tedious, inefficient design processes, and inadequate software solutions.

The software provides benefits throughout every project design phase, with efficiency gains compounding from as early as Stage 2.

Beyond efficiency advantages of the software, their main goal is to empower engineers to create high-quality designs.

A global user base relies on the CIBSE verified design software.

The h2x workflow consists of the following:

• Step 1: Upload the PDF floor plan
• Step 2: Set your calculation parameters
• Step 3: Draw the system layout
• Step 4: Review the automated calculation results
• Step 5: Download the calculations, bill of materials, and export the design to AutoCAD or Revit

 

Why Engineers Choose h2x

There is a wide range of benefits that users enjoy with h2x; these include, but are not limited to, the following:

• Increased productivity: h2x makes it possible to complete designs and calculations in a fraction of the time compared to alternative solutions
• Accuracy: The software highlights issues during the design process to prevent errors, while verified CIBSE calculations give users confidence that their results are correct
• Autodesk compatibility: Once their designs are complete, users can seamlessly export their designs from h2x into Revit and AutoCAD
• Intuitive user interface: Learning how to use the software is quick and easy, so users can get up and running without requiring rigorous and time-consuming training
• Instant redesigns: h2x allows users to easily make changes to their designs and calculations as the project stages evolve and the building layout changes
• Easy deployment: Teams can access h2x’s cloud-based software from anywhere: the office, home, or on-site
• Customer support: Rated 4.9/5 for customer support, the global team is always available and ready to assist in whatever way they can
• Software updates: h2x’s development team makes improvements to the software every week, meaning the product is constantly improving

 

“h2x is the complete software package that is a breath of fresh air compared to alternative hydraulic calculation software on the market. The usability of the system was effortless compared to its competitors in the UK.”

– Daniel, Director of Design 24 Consulting

#2 MagiCAD

MagiCAD is a Revit plug-in used by architects, engineers, and other professionals to create accurate, detailed drawings. The tool offers a wide range of features that allow you to create complex drawings.

The solution includes several BIM tools such as Dynamic Simulation, Electrical Designer, and Mechanical Designer. Dynamic Simulation allows users to create building simulations based on UK building regulations, while streamlining is possible via a single standard building model.

MagiCAD also provides users with the following:

• An extensive library of manufacturer content: You can select the products you need, like valves, radiators, and diffusers, from Europe’s largest library of manufacturer-verified BIM objects.
• Localised standards for integrated engineering calculations: MagiCAD models its BIM objects from physical products to a high level of detail, with the manufacturers’ correct dimensions and technical information.
• Plugins and selection tools: MagiCAD provides a wide range of plugins for directly connecting manufacturers’ product selection, configuration and sizing software into MagiCAD.

 

#3 Stabicad

Stabicad is another Revit plug-in that allows engineers and contractors to increase efficiency while designing complex systems. Industry experts have also verified the tool’s advanced calculation capabilities to ensure accuracy.

Whether you’re working on HVAC systems, electrical networks, or other complex projects, Stabicad is known for its robustness and compliance with crucial industry standards.

Stabicad offers several key benefits:

• Design accuracy: Stabicad’s suite of calculations complies with the IET Wiring Regulations and CIBSE’s SVA. Stabicad lets you produce accurate calculations directly in the 3D model.
• Detail: Change design components from generic to detailed and back again, allowing you to design to the level of detail that suits your project.
• Custom workflows: Trimble Connect lets you easily auto-sync your new and existing projects to the cloud with just a few clicks.

 

#4 Cadline

Part of the VinZero Group, Cadline Ltd provides technology and services to improve business performance and support customers in project design, analysis and collaboration. Their software solutions are built to help users design everything from the 2D schematic to the most complex 3D building.

Coordination and analysis tools help keep designs on track throughout the process. Users can then manage designs and project data with extended teams using data management and cloud-based collaboration platforms.

In addition to that, users can also benefit from Cadline’s:

• Support 360: A dedicated support team takes unlimited calls via phone, email or online, allowing you to focus on what you do best — your projects.
• Training: Cadline offer dedicated training teams with core teaching skills and industry experience to help maximise the business’s software investment.
