Why start your Hysopt Designer trial?
See how physics-based HVAC engineering helps you design better-performing systems in less time.
✔ Reduce oversizing
Replace engineering assumptions with physics-based system validation.
✔ Eliminate engineering rework
Update the model once and automatically recalculate the entire HVAC system.
✔ Validate hydraulic performance
Detect conflicts, missing components and design issues before construction.
✔ Design faster with confidence
Start from 160+ proven HVAC system templates instead of a blank page.
Proven results on real HVAC projects
Discover why engineering teams use Hysopt to reduce project risk, improve engineering productivity and deliver HVAC systems that perform as designed.
WHAT HVAC PROFESSIONALS SAY ABOUT HYSOPT
Trusted by engineering teams worldwide
From consultants and contractors to technical directors and building owners, Hysopt helps organisations improve engineering quality, reduce risk and deliver better-performing HVAC systems.
"From insight to supervision with a single Hysopt model. With Hysopt, we identify opportunities to decarbonise the built environment. We then translate those insights into practical solutions during project delivery."
“It’s more trustworthy than Excel — you can easily make mistakes there, while with the software it’s easier to detect faults.”

“I don’t know any software that does what Hysopt does. We just have to be honest — I haven’t come across it.”
“Hysopt already helped us identify pumps that were either too small or oversized — those are mistakes you really want to catch early.”
“Hysopt has been brilliant — perfect for what we needed. It paid for itself with the very first project.”
“We’re not a typical installation company, and that’s exactly why Hysopt helps us make our designs smarter and more efficient.”
“Hysopt helps us work faster and more accurately. It allows us to back our designs with real data, and that’s something our clients value.”
“I see Hysopt as my Swiss army knife — it allows me to gain insight into the dynamic behaviour of a system very quickly and early in a project.”
"What personally convinced me was the ability to compare multiple system concepts side by side and simulate them dynamically using a Digital Twin."
"The added value of Hysopt lies in its ability to optimize all parts of the hydronic systems and provide all insights needed over the full range of operation."
"Thanks to Hysopt, we're now witnessing consistently high-quality designs emerging from the design team, revolutionising our approach to projects and enhancing our reputation."
"The greatest benefit of using Hysopt is its ability to eliminate uncertainties, allowing us to efficiently and effectively identify and address all system issues."
